About the Native Instruments B4  
Introduction  
The B4, in perspective...  
Congratulations on your purchase of the Native Instruments B4. The B4  
combines the classic and robust tonewheel organ and rotating speaker sound  
with the convenience of software.  
The original B3 organ set many standards with its beefy sound and unique  
interface. This instrument spans all genres – from R&B to Jazz, House to Gospel  
– and is a valuable tool for any player or producer. The Native Instrument B4  
honors this standard, and provides a software that maintains the classic look,  
lush tone, and famous presets of the original.  
B4 II – 5  
 
Of course, there are a number of advantages the B4 has over the original  
tonewheel organ, including:  
• Reduced size and weight  
• Increased preset storage  
• Velocity sensitivity  
• MIDI automation of all parameters  
• Multiple organ models in one package  
• Integrated reverb  
• A ample selection of cabinet models  
The Native Instruments B4 integrates seamlessly into the computer-based  
virtual studio.  
It is important to note that the B4 is not another sampled organ, but a  
complete software model of the tonal characteristics of the original tonewheel  
and rotating speaker and cabinet system. Effects like harmonic foldback  
(tones repeating in octaves at the high and low extremes of the keyboard) and  
loudness robbing (the same tone triggered with multiple keys “compressing”  
the tone volume) are faithfully reproduced as critical characteristics of the  
instrument. This attention to the details of sound production make the B4 a  
stunningly realistic and useful musical instrument.

Installation under Windows XP  
Software Installation  
Insert the B4 II CD into the CD drive.  
Use the Windows Explorer to view the contents of the CD.  
Start the installation by double-clicking B4 II Setup.exe.  
The setup program will suggest C:\Program Files\Native Instruments\  
Product Name\ as the path for the destination folder. You may also  
choose another folder if you wish.  
Installed Folders, Files, and Links  
The setup program creates a new folder called B4 II\ in the installation directory  
(Program Files\Native Instruments). This folder contains the files required to  
operate the software. If you do not choose a different program group during  
the installation, links to the Product and a ReadMe file are added to the Start  
menu under Programs/Native Instruments.  
VST plug-in Installation  
Insert the Installation CD into the CD drive.  
Use the Windows Explorer to view the contents of the CD. To start,  
double-click the B4 II Setup.exe file.  
When the choice is given by the installer, select VST plug-in from the  
list of components to install.  
You can now choose to automatically search for the VST plug-in folder  
or manually select the VST plug-in folder of your choice. Please select  
the option that best suits your installation requirements.  
Note: If more than one host program for VST 2.0 plug-ins is installed  
on your computer, the installer lets you install to multiple VST-folders  
by shift-clicking them. If you decide to install them at a later date,  
simply copy the “B4 II VST.dll” file into the VST plug-ins folders of  
these programs. Windows: If the VST plug-in files are not visible in  
the Windows Explorer, select the Show All Files option. This option is  
located in the Explorer menu View Folder Options... on the View tab  
below Hidden Files. Optionally, you can set up your programs so that  
they all use the same VST plug-ins folder.

Product Authorization  
Part of the B4 II installation is a Product Authorization which has to be fullfilled  
in order to make permanent use of the software. We recommend that you  
take notice of this chapter first, then proceed with the software installation as  
described in the following chapters and finally return to this chapter.  
What is the Product Authorization?  
The Product Authorization includes a full registration. After having completed  
the authorization, you can make use of all online services related to the  
registered product. On the Native Instruments website you can read online  
tutorials, get technical support, participate in the NI forums and download  
updates.  
B4 II requires the Product Authorization in order to use the software perma-  
nently. You can run B4 II for 30 days without any limitations. As long as the  
software runs unauthorized a message at every program start reminds you  
that the authorization has not been completed yet and indicates how many  
more days the software is running without an authorization.  
The Product Authorization is performed by a small application called  
Registration Tool. The Registration Tool generates a so called System ID  
which serves as request code for receiving an Authorization Key. The System  
ID is based on some hardware components of your computer system, the  
operating system version and the serial number you have entered at the B4  
II installation.  
B4 II – 9  
 
Note: Exchanging your audio card, MIDI interface or external equipment  
will not start the request for a new Authorization Key. Only exchanging a  
basic hardware component in your computer or installing a new operating  
system might produce a new Product Authorization request. In this case  
the Registration Tool will reflect the change by displaying a new System  
ID and you have to repeat the Product Authorization.  
The System ID has to be sent to Native Instruments in order to receive the  
Authorization Key which allows the permanent use of B4 II. Since the Product  
Authorization is part of the license agreement B4 II will stop launching after  
30 days if it was not authorized until then. Of course, it is also possible to  
complete the Product Authorization after 30 days. In this case the software will  
launch again as soon as the Product Authorization has been completed.  
Note: The data transfer at the online Product Authorization is done via  
a secure connection using 128 bit encryption. Native Instruments keeps  
your personal data like email and postal address in confidence. No data  
will be passed to a third party.

Audio Interfaces  
Audio interfaces, which include software routines called drivers, allow B4 II  
(and other programs you have installed, if present) to communicate with your  
computer’s audio hardware. This section describes how to use various audio  
interfaces with B4 II.  
There are two main ways to implement B4 II:  
As a “standalone” device that requires no host software. The application’s  
audio and MIDI connections interact directly with your computer’s audio/MIDI  
hardware interface.  
As a plug-in that works in conjunction with a “host” program, such as  
sequencing or hard disk recording software. In this case, the host program  
interacts directly with the computer’s hardware interface. B4 II connects to the  
host program via “virtual patch cords.” The audio outputs appear as signals  
in the host’s mixer, and the host passes MIDI data to the software.  
We’ll describe each mode in detail, but first let’s look at the various  
interface drivers and plug-in formats used by different operating systems  
and programs.  
Standalone Application  
B4 II works in standalone mode with ASIO, MME, DirectSound, and Core  
Audio. The software/computer combination acts as an instrument, similar to  
a hardware digital synthesizer. The table shows you which drivers are available  
under which Operating System:  
Driver  
ASIO 2.0  
DirectSound  
MME  
Windows  
MacOS X  
Core Audio  
Plug-In  
Used as a plug-in, B4 II is not a standalone program but rather a program  
“module” that can be integrated into a “host” program such as a sequencer.  
plug-in mode allows you to integrate it seamlessly with the sequencer.  
Furthermore, it has many other uses as a plug-in:  
18 – B4 II  
 
• MIDI sequencing of B4 II and audio mix-down of the MIDI tracks within  
a single program  
• Comfortable automation of B4 II parameters in the sequencer  
• Further processing of B4 II signals using additional plug-ins  
• Sample-accurate timing with MIDI controllers (when used as VST 2.0  
plug-in)  
• Restoring of all plug-in settings when the host document (such as a  
song file of the sequencer) is loaded  
• Integration with other instruments into a “virtual studio”  
Some shortcuts / key commands do not work in all sequencers. This is  
due to the fact that the host capture keys for themselves and do not  
pass them on to the plug-in.  
This table provides you with an overview of which interfaces are supported  
by which host programs:  
Plug-in Interface  
VST 2.0 Plug-in  
DXi  
Host-Program  
Cubase, Nuendo  
Sonar  
Windows  
Mac  
Audio Units  
Logic  
Note: Some hosts include “wrappers” that allow running B4 II with  
a choice of plug-in protocols. Try each one, as one may offer better  
performance than another. Example: With Sonar, running B4 II as a  
DXi instrument allows using multiple outputs, while running it as a VST  
instrument provides more automation options  
Interface Details  
The interfaces described below represent different ways B4 II can communicate  
with your sound card. Available interfaces depend on your computer, the  
audio interface (sound card) you’re using, and your computer platform (B4  
II supports Windows XP or MacOS X). Choose the fastest interface protocol  
supported by your interface, which will likely be ASIO with Windows, or Core  
Audio for Mac. For Windows, you can also use DirectSound and Multimedia  
(also called MME), but expect a significant delay (called latency) between the  
time you play a note and the time you hear it.  
ASIO (Audio Streaming Input Output): This cross-platform plug-in protocol  
B4 II – 19  
 
was developed by Steinberg. It is highly recommended for its low latency,  
multi-channel audio card support, and high performance.  
DirectSound: Developed by Microsoft, this is a is a component of DirectX 5.0  
or higher for Windows. How well DirectX works well depends on your sound  
card. If you adjust the interface for an acceptable amount of latency, you  
may hear glitches and clicks in the audio output that can only be fixed if you  
increase latency.  
MME (Multi Media Extension): This is the standard Windows audio driver.  
Most sound cards support this interface and work with it quite well. However,  
MME is even less suitable than DirectSound for real-time applications due to  
its comparatively high latency.  
Core Audio: This audio interface for MacOS X is integrated tightly into the  
operating system, and works with external audio hardware as well as the Mac’s  
integrated audio output.  
Plug-In Details  
VST (Virtual Studio Technology): Like ASIO, this cross-platform plug-in  
technology was developed by Steinberg. It is the most common plug-in format,  
and many programs are optimized to work with VST plug-ins.  
DXi2 (DirectX Instrument 2): Based on Microsoft DirectX technology, this  
plug-in interface for software synthesizers and instruments is designed for low  
latency and high performance on the Windows platform. Cakewalk Sonar and  
Image Line FL Studio are the most well-known hosts that support DXi.  
RTAS (Real Time Audio Suite): This interface protocol from Digidesign allows  
using plug-ins with ProTools (or other Digidesign-compatible software). Unlike  
traditional TDM effects that depend on using Digidesign hardware, RTAS plug-  
ins are “native”. This means the host processor performs all computations  
needed for the plug-in.  
AU (Audio Units): This plug-in format is exclusively for the Macintosh OS X  
platform, and is tied in closely with the operating system.  
More About Latency  
As with any digital device (including hardware signal processors) that convert  
audio to data and back again, a computer adds a certain amount of delay  
(“latency”) when processing audio signals. Fortunately, with today’s computers  
and low-latency sound card drivers, this delay can be so small that you can’t  
hear it (e.g., under 3 milliseconds, which is about the same delay caused by  
moving your head one meter further away from a speaker). However, typical  
20 – B4 II  
 
computers are generally not set up for low latency; attempting to play in real  
time through B4 II will probably be unsatisfying because of the delay.  
Any computer-based audio system has some delay between the audio input  
and output. As a result, if you’re playing a MIDI keyboard through B4 II, you  
may hear an annoying delay between the time you hit a key and hear a sound.  
Even the most powerful computer can only do a certain number of calculations  
per second; generating and processing sounds demands a lot from a computer,  
so it’s important to minimize any computer-based delays.  
Fortunately, three main factors make delays virtually insignificant, assuming  
you have a suitable computer setup (see System Requirements).  
• Today’s multi-GigaHertz computers are so fast they dramatically reduce  
latency.  
• Many sound cards and audio interfaces include drivers optimized for  
low latency.  
• NI’s software has been optimized to function as efficiently as  
possible.  
Use Low-Latency Drivers  
Drivers are pieces of code that handle communications between your computer  
and audio interface, whether built into a computer or attached via USB or  
FireWire. The more efficiently they transfer data between audio interface and  
computer, the lower the latency.  
B4 II works with two low-latency driver types:  
ASIO (Advanced Streaming Input Output). This cross-platform protocol  
was originally developed by Steinberg.  
Core Audio (Mac only). This low-latency protocol was created by Apple  
for the Macintosh, starting with OS X.  
If your audio interface does not support one of these protocols, you will likely  
hear an audible delay if you play through B4 II in real time. Although B4 II can  
work with the DirectSound and MME drivers common in Windows machines,  
you will probably not have a satisfying playing experience.  
How Low Can You Go?  
1.5 ms of latency approaches the theoretical minimum, because it will always  
take some time to convert a keyboard press into MIDI data, than convert B4's  
digital audio out to analog. However, note that ultra-low latency settings (or  
higher sampling rates) make your computer work harder, which may limit the  
B4 II – 21  
 
polyphony or number of effects you can add while still retaining glitch-free  
audio. So, here are some tips on living with latency.  
About Samples and Buffers  
Audio cannot be handled continuously by a computer, but has to wait its turn  
while other operations are being carried out. As a result, sound cards create  
a “buffer,” which can hold a certain number of samples, where data can be  
stored and released as needed to create a smooth flow of data. An analogy  
would be if you had a hose that didn’t deliver water continuously, but in bursts.  
So, you use a holding tank to store the water coming in from the hose, and  
have a valve in the tank that releases a steady amount of water in a smooth,  
continuous flow.  
If the tank (buffer) is large, then you can store more water in case the hose  
goes dry for a bit. But it will take longer to fill the bucket, which is equivalent  
to latency. A smaller tank takes less time to fill, but the hose had better deliver  
water on a pretty continuous basis.  
All ASIO audio interfaces and sound cards include a control panel where you  
can adjust latency. This may be given as the number of samples per buffer,  
as shown in the Terratec EWX control panel:  
For example, the Terratec EWX ASIO control panel lets you choose a particular  
number of samples/buffer. The display then shows the resulting latency. In  
this case, 256 samples/buffer has been selected, giving latency of just under  
6 ms at 44.1 kHz. Setting this to 128 samples/buffer will reduce the latency,  
but may stress out your computer more.  
Some control panels simply show the latency that results from choosing a  
particular setting in milliseconds rather than showing samples/buffer.  
22 – B4 II  
 
In this screen shot, note that Creamware’s ASIO control panel simply lets you  
choose the desired latency; buffers are adjusted “behind the scenes” within  
the Creamware Scope application (in this case, to 128 samples). The Device  
Setup panel in Cubase confirms the latency, which is about 4 ms, but doesn’t  
indicate the buffer size.  
Warning: Different Types Of ASIO  
It’s extremely important to use the ASIO driver written for the card you’re using.  
There are also “generic” ASIO drivers, typically called (for Windows) “ASIO  
DirectX Full Duplex Driver” or “ASIO Multimedia Driver.” They will usually be  
found in a drop-down menu in the host program where you choose the desired  
ASIO driver. If you’re not sure which one to use, try them all, and choose the  
one with the lowest latency. There should be an obvious, dramatic difference  
when you use the correct ASIO driver.  
B4 II – 23  
 
Tips On Minimizing Latency  
Set latency to the highest comfortable value. 256 samples/buffer is  
very responsive yet gives your computer some “breathing room.” 512  
samples may also be acceptable; anything more will create too much  
delay. If you can’t get reliable audio with 512 samples, it’s time for a  
better computer!  
If your ASIO Control Panel shows latency in milliseconds, you’ll find  
that anything over 10 ms or so gives an audible delay. 5 ms is a good  
compromise between speed and minimum stress to your computer.  
Download your sound card’s latest drivers from the manufacturer’s web  
site. This can make a huge difference in performance.  
If you are recording in a host application and using software synthesizers,  
use your program’s “freeze” function (if available) to disconnect some  
synths from the CPU. Or, render a soft synth’s output as a hard disk  
audio track (then remove the soft synth), as audio tracks are less taxing  
on the computer. Hint: If you retain the MIDI track driving the soft synth,  
which places virtually no stress on your CPU, you can always edit the  
part later by re-inserting the soft synth.  
Sometimes there are two latency adjustments: A Control Panel for the  
sound card sets a minimum amount of latency, and the host can increase  
from this value if needed. Or, the host may “lock” to the control panel  
setting.  
24 – B4 II  
 
B4 II as standalone  
When used as a plug-in, the host program has already set up its audio and MIDI  
connections, and B4 II simply “plugs in” to these. However, with standalone  
operation B4 II communicates directly with your audio interface. It’s therefore  
necessary to specify audio and MIDI settings, as well as the preferred driver  
protocol (of course, plug-in format is not an issue).  
Setup for Mac and Windows machines is essentially identical, except where  
indicated. Note that if you change your audio interface, you will almost certainly  
need to re-adjust these settings.  
Call up the Audio + MIDI Settings setup dialog from the Setup menu. You’ll  
see three tabs for Soundcard, Routing (audio output patching), and MIDI.  
Soundcard (Audio Interface)  
Audio + MIDI Settings dialog  
Interface: Choose the fastest interface protocol supported by your interface,  
which will be ASIO or Core Audio. For Windows, you can also use DirectSound  
and Multimedia (also called MME), but expect a significant delay between the  
time you play a note and the time you hear it.  
Windows only: Avoid using any drivers listed as “emulated,” as they  
provide poorer performance than other drivers. For example, although  
DirectSound drivers generally outperform MME drivers, MME drivers  
will outperform emulated DirectSound drivers.  
B4 II – 25  
 
Sample rate: The drop-down menu will display compatible sample rates for  
your audio interface. 44.1kHz is the same sample rate used for CDs, and is  
the most “universal” choice. However, some audio interfaces offer 48kHz and  
96kHz (B4 II accepts up to 96kHz sample rates). These higher rates stress  
your computer more, but offer somewhat better high frequency response. If  
you are using B4 II standalone, choose whichever rate you prefer. When used  
as a plug-in with a host program (e.g., Cubase, Digital Performer, Logic, Sonar,  
etc.), the host will determine the sample rate.  
Output Device: Use ASIO written specifically for your audio interface (not  
“ASIO DirectX” or “ASIO Multimedia,” unless no other choices are available),  
or for the Mac, Core Audio.  
Output Latency: This field displays the output latency. For some drivers you  
can adjust the latency individually using a fader.  
Adjust latency for the fastest possible setting that gives consistent audio  
performance. The CPU may not be able to keep up with fast settings, result-  
ing in possible crackles or pops in the audio. Slower settings will give more  
consistent audio performance, but the amount of delay may be musically  
unsatisfying.  
Experiment with the latency setting until you find the best compromise be-  
tween consistent audio performance and fast response. A quick way to adjust  
latency is as follows:  
Select any instrument and play it while moving the Latency slider.  
Move the Latency slider to the left until you start to hear clicks in the audio  
output.  
Now move the slider to the right until the clicks disappear. This is the opti-  
mum setting.

Routing  
Using the drop-down menu, Output 1/2 is assigned to an output from a multi-  
output sound card.  
If your sound card offers multiple outputs, you can choose which ones connect.  
Click on Outputs to select the outputs from drop-down menus.  
Similarly, use input to select the audio input if you wish to use B4 II as an  
effect.  
If you experience a humming or buzzing, maybe even feedback, when  
you start B4 II, it is likely that you have the B4's input set to your  
computer's built-in microphone. Please select another input or disable  
input altogether by choosing "not connected" from the drop-down  
menu.  
B4 II – 27

B4 II as Instrument Plug-in  
Plug-ins come in two forms, virtual instruments and audio effects. Most of  
you will use B4 II as a virtual instrument, but that shouldn't discourage you  
from also using it as an effect. Just plug B4 II into any audio track to use  
the various cabinets and speakers for signal processing. The instructions in  
the following section can be used to get started with B4 II instrument and  
your host.  
VST 2.0 Plug-In  
Using the B4 II in Cubase SX 3  
Launch Cubase, go to the Devices menu option and select the VST  
Instruments menu option or press F11 on your keyboard.  
A window showing the instrument rack appears. Click on an empty slot  
and choose B4 II from the available list of instrument plug-ins.  
The plug-in will now appear in your list and automatically be turned on.  
It will also create a set of audio channels in your VST mixer that will be  
used for mixdown within your project. This will allow you to mix, pan,  
and process B4 II's output just like any other existing audio track in  
your Cubase song.  
Click on the Edit button to call up the B4 II interface. Here you can  
control and edit all the features and functions that B4 II has to offer.  
Now go to the "Project" page and add a MIDI track (if you do not have  
one already created).  
Go to the Output parameter section for this MIDI Track and click on  
the field. This will create a list of available MIDI out ports to assign to  
this MIDI track. Choose B4 II from the list.  
Note: If a product does not appear in the list of available VST instru-  
ments inside Cubase then you may need to enable it manually via the  
Devices/plug-in information window. If the product does not show up  
B4 II – 29  
 
there, then it may not be installed correctly. Please refer to the previous  
section on installing the plug-in for both Windows and Mac platforms  
for more assistance on setting this up.  
After having loaded an Instrument from the library you should be able to trig-  
ger it via MIDI using a keyboard controller. B4 II’s sound will generate through  
the VST mixer and directly to your sound card. If the plug-in does not receive  
MIDI or generate audio, then make sure to check the following areas:  
• Make sure "MIDI thru" is enabled in Cubase.  
• The MIDI channel of your MIDI track must correspond to the receive  
channel of the loaded instrument.  
• Make sure that you have properly configured your sound card for use  
with Cubase.

The B4 User Interface  
The B4 “Manual View”  
You can adjust all of the front panel controls with your mouse. Additionally,  
you can test the current sound by clicking on the keys of either manual or  
the foot pedals.  
The B4 Control Center  
The B4 Control Center is always displayed and contains the interface to guide  
you around your virtual organ. You can quickly select presets with the Preset  
Menu and switch to the different views to accomplish the tasks at hand.  
The View Selection  
Switching around the interface…  
There are five views in the B4. Each displays different types of performance  
and/or programming controls.  
B4 II – 37  
 
The Manual View is an “organ keyboard” view, which includes all three manuals  
(the upper and lower as well as the pedals), the three drawbar sets, the  
expression pedal and the performance switches. This is a good view to use when  
you are doing manual drawbar editing, and want to be able to “manually” strike  
the keys. These editing controls are covered in more detail in the “Creating  
Your Sound” section of the manual.  
The Organ View displays the most important editing controls used for  
programming your B4. It includes many of the program functions from the  
Manual View, but does not display the keyboard manuals or pedals.  
The Organ View has several editing sections, providing control over various  
tonal organ parameters, the modeled tube amp, plus various cabinet model  
and microphone options.  
38 – B4 II  
 
The Expert View displays an additional set of controls for the tonewheel models,  
percussion and vibrato details, reverb, and the rotary effects. The major organ  
controls, like the drawbars, the Rotator controls, and the vibrato/percussion  
buttons are also available in the Expert View.  
These settings are also covered in more detail in the “Creating Your Sound”  
section of the manual.  
The Preset View shows everything you need to organize your organ sound  
library. It also includes a simple midifile player and options for import and  
export of presets.  
B4 II – 39  
 
Last but not least, the Setup View helps you with setting up various MIDI  
channel options and with assigning MIDI controllers to the dials and switches  
of the B4. You will also use it for setting up MIDI channels, keysplits and  
manual transpositions.  
Most of the time you will work with the Manual- and Organ Views, as these  
contain the more performance-oriented controls. The Expert View is geared  
towards in-detail editing.  
The Presets Menu  
Let’s see what’s on the menu…  
The Control Center’s presets menu provides control over the B4 keyboard  
presets. Unlike the original tonewheel organs, the Native Instruments B4  
stores multiple sets of presets for recall.  
The Control Center is always visible, independently from the currently activated  
view.  
Presets can be recalled by entering a number in the Preset Number field on  
the left side.  
By clicking on the preset name you can choose a preset from the drop-down  
list.  
40 – B4 II  
 
Up : Loads the previous preset on the list.  
Down : Loads the next preset on the list.  
Store: Immediately stores the current setting in the current preset and  
overwrites it.  
The Preset View gives you more controls for handling presets and is described  
in the next section of this manual.  
Using Presets  
The B4 puts a broad range of organ sounds at your fingertips, giving you rapid  
access to a library of 120 presets, divided into 10 banks of 12 presets each.  
Individual preset hold the drawbar settings and every other user adjustable  
parameter that defines the instrument´s sound.  
Manual View  
In the Manual View, presets can be selected by hitting one of the “reverse  
image” keys – the keys on the left side of the keyboard that have black naturals  
and white accidentals. Presets selected from the upper manual change the  
settings for the entire instrument. Presets selected from the lower manual  
only change the lower manual and the pedal drawbars. Selecting a preset will  
immediately move the drawbars to the stored setting.  
Note: Unlike the B3, there is no “Cancel” preset. On the B3, the Cancel  
preset allowed direct manipulation of the drawbars to determine the  
sound of the organ. With the B4, the drawbars are always active, they  
reflect the sound of the current preset and are always editable.  
Banks are selected using the Bank Select Control on the “wooden” end block  
of the upper manual. Selecting a new bank will immediately change the  
preset in use, and therefore change the drawbars to match the newly selected  
preset.  
B4 II – 41  
 
Of course, you can also use the preset section displayed in the Control Center  
to change presets or navigate to the Preset View to get a better overview over  
your currently available presets.  
Organ and Expert View  
Use the preset menu/ arrows buttons to change and the Store button to  
overwrite presets.  
Presets can also be selected using MIDI Program Change commands. Program  
numbers determine the bank and program to be selected. For example, Program  
Change numbers 1-12 are in Bank 1, 13-24 are in Bank 2 etc.  
At any point, you can change the current sound of each manual by adjusting  
the manual drawbars. The drawbars are automatically changed when a new  
preset is selected, so they always correspond directly to the current sound.  
Saving Presets  
Programming the B4 can allow you to create new and unique organ sounds.  
As described below, you can use the drawbars to determine the sound played  
with the keyboard manuals. Additionally, the Organ and Expert View settings  
can add realistic detail to the sound. Learning to use these setting is at the  
heart of creating a personal organ/speaker voice.  
Once you’ve created a sound you want to keep, you can save the settings as  
a preset. To save an edited sound as a preset, you need to click on Store in  
the Control Center or use the controls on the Preset View. There you will also  
find the Store To command letting you store presets to new locations in the  
preset memory.  
All parameter settings, except expression pedal (swell), are stored in the given  
memory location.  
42 – B4 II  
 
Exporting Presets  
In sequencers, the preset memory is saved as part of the song that uses the  
B4 plug-in. But you will probably also want to export your presets to a file.  
You can save all 120 presets in memory as an “export” file using the Save  
function on the Preset View. If you only want to export the current sound as  
a single preset, you can use the Save Single function. These files allow you  
to share presets with other B4 users or to store settings for later use.  
If you are running the B4 in standalone mode, the Load and Save functions  
are also available via the File Menu.  
The Preset View  
Organizing the library of organ sounds…  
In the upper part of the Preset View you can see the preset list. Click on a  
preset to load it. With the page buttons below the presets list you can flip  
through all 7 pages containing all 120 presets. The Left button flips one page  
backwards and the Right button flips one page forward.  
You can also use the mouse to drag and drop presets to new locations in the  
list. By doing this the other presets will be shifted to new locations. With this  
function you are not going to overwrite existing presets.  
B4 II – 43  
 
If you want to rename a preset, double click on its name and type in a new  
one.  
To store a preset you should use the Store To command. This important  
command lets you store presets in a location other than your currently selected  
preset. After clicking Store To you select the desired preset slot on the preset  
list and your new sound will get stored. Be careful, though, you will overwrite  
the preset that formerly dwelled in that location  
The B4 also sports a small MIDI file player. You can use it via the following  
controls:  
Audition Buttons: We have prepared some MIDI recordings to help you test  
sounds. Pattern one plays a short jazz pattern, with number two it is blues  
and rock for number three.  
Play: Toggles playback of the currently loaded midifile on and off. This acts  
as a combined play/pause button.  
Stop: Stops playback of the currently loaded midifile.  
Open Midifile: Opens a midifile to be played by your B4 organ.  
The next bunch of buttons deal with managing the preset list and with import  
and export of presets to and from disk.  
44 – B4 II  
 
List Operations  
Store To: After clicking Store To you select the desired preset slot on the preset  
list and your current settings are stored into that preset slot.  
Delete: This command deletes the currently selected preset, leaving an empty  
preset slot.  
Compact List: This command pushes all empty preset slots to the end of the  
list. All presets will get renumbered accordingly.  
Protect!: If toggled on, this option prevents all presets from being overwritten.  
The memory is protected.  
Undo: By clicking Undo the last command in the preset view gets undone.  
You can step back up to 30 commands. When you save the list as a complete  
package, the undo stack gets deleted.  
Redo: By clicking Redo the last command that got undone with the Undo  
function is executed again.  
File Operations  
Load: This command imports all 120 presets from a preset file into the B4’s  
preset memory. This is how you load presets from NI or other B4 users.  
Save: The Save option exports all 120 presets from the B4’s preset memory  
to a preset file.  
Under Windows, the filename extension for a file with 120 presets is b4a.  
Load Single: This command will import a single preset from a preset file. The  
contents of the file are loaded as the current sound setting without affecting  
the preset memories. It is loaded into the preset buffer.  
Save Single: This command exports the current sound setting as a single  
preset to a preset file.  
Under Windows, the filename extension for a file with one preset is b4p.  
B4 II – 45  
 
Keyboard Splits  
Unlike most instruments, the B4 must implement multiple keyboard ranks  
(called manuals in organ parlance). This is accomplished in two ways: either  
by responding to multiple MIDI channels, or by supporting keyboard splits.  
When using multiple MIDI channels (No Keyboard Split), the default response  
to MIDI information is as follows:  
Notes, Controls, and Program Changes received on MIDI channel 1 are used by  
the entire instrument. Program Changes received on channel 1 are equivalent  
to selecting a preset from the upper manual preset keys.  
Notes, Controls, and Program Changes received on MIDI channel 2 are used by  
the lower manual. Program Changes received on channel 2 are the equivalent  
of selecting a preset from the lower manual.  
Notes and Controls received on MIDI channel 3 are used by the bass pedals.  
Program Changes received on channel 3 are treated as if received on channel  
2.  
You can change these default settings by choosing different MIDI channels  
on the Setup View. Please refer to the corresponding section in this manual  
for further information.  
Using this method for handling MIDI data, it is easy to maintain production  
control from your sequencer or multiple MIDI keyboards.  
When using keyboard splits, the MIDI information received on MIDI channel  
1 is sent to the different manuals based on the keyboard split locations. In  
all cases, the upper manual is controlled using the highest MIDI notes, and  
the pedals are controlled with the lowest notes.  
Using the keyboard split mode, it is easy to play all three manuals “live” with  
just one keyboard, allowing a skilled player to simulate the complex manual  
control of a hot B3 player.  
Setting Split Points  
To split the notes received on MIDI Channel 1 between the B4’s upper and  
lower manuals right-click with your mouse on the desired key on the on-screen  
keyboard.  
46 – B4 II  
 
On the resulting menu choose Set Upper Keyboard Split to define the upper  
split point. This key and all above it will play the upper manual from now on.  
The keys below it play the lower manual.  
Similarly, use the menu entry Set Lower Keyboard Split to set the split point  
between the bass pedals and the lower manual.  
When Keysplit is activated, the split points are shown with markers on the  
upper manual in the Keyboards View.  
To delete your keyboard splits, right click again on the upper manual and  
choose No Keyboard Split from the resulting menu.  
B4 II – 47  
 
As an alternative, you can modify the split points on the Setup View.  
Each manual can also be transposed up or down by one octave by right-  
clicking on the respective on-screen keyboard and choosing the appropriate  
transposition settings from the context sensitive menu. This also works for  
the pedals.  
MIDI Response  
The MIDI response of the B4 is similar to any standard MIDI instrument. Once  
you have MIDI reception set correctly, you will find that the B4 will respond  
to the complete range of MIDI notes. As you play “beyond” the range of the  
standard B3’s keyboard range, the notes will “roll over”, or repeat their lower  
values.  
Unlike real tonewheel organs, the B4 will also respond to MIDI Note Velocity  
input. If your keyboard is able to send velocity messages, and if the current  
preset is set to respond to velocity changes (by having the Velocity knob on  
the Organ View turned up), you will find the output levels affected by how  
hard you strike the keys.  
48 – B4 II  
 
The B4 is also able to have all of the on-screen controls manipulated by MIDI  
controller messages. The MIDI controllers used are listed on the Setup View.  
They can be changed to your needs. You can do this either on the Setup View  
(which is described in the next section of this manual) or by right clicking on  
the control and choosing MIDI Learn… from the pop-up menu. Afterwards just  
move the hardware controller you want to assign to that specific B4 control  
and you are done.  
Hint: The B4 can be used with any programmable MIDI controller box.  
The B4 comes with templates (in the form of MIDI Sys-Ex files) for  
various hardware controllers.  
The B4 as an effects unit  
You can route any audio signal through the B4 tone shaping sections. The  
external sound gets in just before the amp section and is mixed with the  
tonewheel signal. This opens up a world of possibilities for shaping external  
sound with the beefy tone engine of B4.  
B4 II – 49  
 
In standalone mode the external signal comes from the audio input of your  
soundcard. Please refer to the Setup View section of this manual for more  
information.  
The FX plugin version of B4 will receive audio input from the host software  
it is running in. Please refer to the respective section of this manual and to  
the documentation of your sequencer or plugin host for information on how  
to route audio into the B4 FX plugin.  
The B4 is not only an organ but a full-fledged simulation of a tube amp and  
rotator rig including a variety of classic cabinets and microphones. Electric  
guitars will feel right at home when plugged into the B4.  
Feel free to experiment and use synthesizers, vocals or whatever audio signal  
you have. You will get a plethora of nice sounds from this approach.  
Setup View  
The technical MIDI side of the B4…  
50 – B4 II  
 
The Setup View is for assigning MIDI controllers, managing controller maps  
and for setting some further details affecting the behaviour of your B4.  
Controller assignment  
On the left you have the Controller Assignment list representing the current  
controller map. The CC column shows the currently set controllers for the B4  
parameters shown in the Name column. Click on the controller number to  
change its value. Press enter to commit the change.  
The MIDI channel for incoming controllers can be defined with the Controller  
Channel dial on the bottom of the Setup View.  
The Mode column sets the behaviour of the B4 parameters that can be operated  
by a switch. If Mode is on, one complete switch/release cycle toggles the  
state of the respective parameter. If Mode is off, the down-state of the switch  
represents one state of the control in your B4 and the up-state represents the  
other. The Mode function is not available for controls that need continuous  
controller input, like dials or drawbars.  
Let’s assume you want to control your rotor brake with a footswitch. With  
toggle active you have to press and release the footswitch to set the control  
into brake mode and press and release again to switch back to run mode.  
In switch mode a down-press switches the brake on and letting go of the  
B4 II – 51  
 
footswitch means run mode. It depends on the parameter to be controlled and  
on your personal taste which Mode setting you should choose. For the rotor  
brake both settings can be useful but you will probably want to use things  
like Percussion on/off with toggle mode.  
Export and import of controller maps is provided via the following  
commands:  
MIDI Learn: With this control you can assign MIDI controllers interactively.  
First you select the parameter to be re-assigned on the controller assignment  
list. Then click MIDI Learn and move the desired knob or fader on your MIDI  
hardware.  
Another way of assigning MIDI controllers to B4 controls is to right-click on  
the B4 parameter on any View and to choose MIDI Learn… from the pop-up  
menu. Then you will have to move the knob or fader on your hardware controller  
and the new assignment is done.  
CC Dump: The current value of all panel controls is sent out as MIDI Controller  
messages. Use this if you have MIDI controller hardware with endless encoders  
displaying the current value of individual controls.  
To round up the controls for MIDI controller management we have:  
Load: This command imports a saved controller map.  
Save: Here you can save the current controller map to disk.  
Be sure to save your customized controller maps so that you can easily restore  
them in case of a system crash. The Load Controller Map / Save Controller Map  
functions are also available via the file menu of the standalone version.  
Under Windows, the filename extension for a controller map is bcm.  
Interfacing  
52 – B4 II  
 
Rig-Kontrol-2 Active: This is for proud owners of the Native Instruments Rig-  
Kontrol 2. Activate this option, if you want to control the B4 with the Rig-  
Kontrol. Please be sure that no Guitar Rig is running when activating Rig-Kontrol  
for the B4. It cannot be used for both at the same time. The default state of  
this control is off. Furthermore you can only use the Rig-Kontrol 2 with your  
B4 in standalone mode.  
Audio Input Active: This control enables/disables the audio input from your  
sound hardware into the B4 standalone version. It is only available for the  
standalone version.  
Audio/MIDI Setup: This brings up the setup window for selecting the audio-  
and MIDI interfaces. Please refer to the respective manual sections in the  
first part of this text for further information. This control is not available in  
the plugin version of B4. The host software takes care of all things audio and  
MIDI for the B4 plugin.  
Controller Options  
Xk3 MIDI Compatibility: Switch on if you want to control the B4 with the  
Hammond Xk3 controller hardware. This piece of kit uses its own protocol to  
communicate with the B4.  
Invert MIDI Drawbars: When using a MIDI controller to control the drawbars,  
this control inverses the effect of pulling/pushing the drawbar.  
CC Dump On Program Change: When this switch is active, every received program  
change sends out the current value of all panel controls as MIDI controller  
messages. You can use this if you have MIDI controller hardware with endless  
encoders displaying the current value of individual controls. The controller  
dump will happen when you switch a preset via the B4 interface and if you  
initiate a program change via your MIDI hardware or sequencer software.  
Drawbar options  
B4 II – 53  
 
2 Pedal Drawbars: When active, the B4 pedals get only two drawbars (16’  
and 51/3’). This does not mean that only two of the normally six drawbars are  
active but that the two drawbars control a mixture of tones. This emulates a  
feature of the original B3.  
Upper Drawbars On Left: When this control is active the upper and lower  
drawbar sections swap their positions in all views.  
Pedal Drawbars In Middle: Activate this if you want the pedal drawbars between  
those for the upper and lower keyboard.  
Percus. Disables 1’ Drawbar: When active and Percussion switched on, the 1’  
drawbars for the lower and upper manuals are deactivated.  
Note: The stock B3 organ has nine contacts for every key, one for  
every drawbar. For the percussion effect one contact has to be used,  
so that one drawbar has to be dismissed. As the Percussion effect is  
only available on the upper manual this control does not apply for the  
lower.  
Manuals setup  
MIDI Channel: Assign individual MIDI channels for the three manuals and  
for the controllers. Click on the value and move the mouse up or down to  
change it. Use this if you are in the luxurious situation of having multiple MIDI  
keyboards for controlling your B4.  
54 – B4 II  
 
Transpose: With the Transpose switches you can transpose each of the three  
manuals one octave up or down. Alternatively, you can switch the octaves of  
the respective manuals by right clicking them in the Manual View and choosing  
the respective option in the pop-up menu.  
Upper/Lower Keysplit: If you want to control multiple B4 manuals with one  
keyboard you can define keysplits. Click into the value field and move the  
mouse up or down to change the note number.  
Upper/Lower Keysplit Learn: This mirrors a command from the context-sensitive  
(right-click) menu of the Manual View. Click the button and press a key on  
your MIDI keyboard to set the splitpoint between pedals and lower manual.  
Upper/Lower Keysplit On/Off: Click to toggle the upper/lower keysplit on and  
off.  
Lower/Pedal Keysplit: If you want to control multiple B4 manuals with one  
keyboard you can define keysplits. Click into the value field and move the  
mouse up or down to change the note number.  
Lower/Pedal Keysplit Learn: This mirrors a command from the context-sensitive  
(right-click) menu of the Manual View. Click the button and press a key on  
your MIDI keyboard to set the splitpoint between lower and upper manual.  
Lower/Pedal Keysplit On/Off: Click to toggle the upper/lower keysplit on and  
off.  
You can also define keysplits in the Manual View. Right-click on the upper  
manual to bring up the menu. Please refer to the corresponding manual section  
for further information.  
Full Screen mode  
If you want to see the B4 without any distractions from underlying windows  
and other OS controls, click the Full Screen button. It is located to the right  
of the Control Center. To leave full screen mode click the button again or press  
the escape key on your computer keyboard.  
B4 II – 55  
 
Creating Your Own Sounds  
Manual View Controls  
The B4 organ in all its glory…  
The B4 provides complete editing functions for all three manuals (upper, lower  
and pedal). This programming is provided by the drawbars and controls on  
the Manual View panel, and the adjustments located on the Organ and Expert  
Views. Using these edit functions, you can create new and exciting sounds to  
accentuate your music. The front panel controls are:  
Vibrato Switches  
The trademark sound produced by the patented Scanner Chorus/Vibrato system  
can be switched on and off for the upper and lower manuals independently.  
The bass pedals use the same setting as the lower manual.  
56 – B4 II  
 
Vibrato Setting  
The Vibrato Setting switch allows for quick changes to the depth of the chorus  
or vibrato effect. The switch has six settings:  
V-1, C-1, V-2, C-2, V-3, C-3.  
These settings determine the depth and mix of the Scanner Chorus/Vibrato  
effect. In fact, changing these switches will change the Depth and Mix settings  
found on the Expert View.  
V stands for Vibrato effect and C is Chorus. The number indicates the depth  
of the effect.  
Pedal Drawbars  
6 Drawbars setup the sound for the bass pedal channel. Anything is possible,  
from pure deep sine bass, to grooving wooden bass tones, to full orchestral  
sound. The drawbars include the 16’, 5 1/3’, 8’, 4’, 2 2/3’ and 2’ settings (in  
other words, just like the first six drawbars from the other manuals). Because  
preset selection will change the drawbars to the new settings, the drawbars  
always represent the current bass pedal sound. If you would like to stay true  
to the original B3 you can go to the Setup View and switch on the 2 Pedal  
Drawbars feature. By doing this, you will have only two drawbars (16’ and  
51/3’) for the pedals.  
Note: This setting does not mean that only two of the six drawbars are  
active but that the two drawbars control a mixture of tones.  
B4 II – 57  
 
Lower Manual Drawbars  
9 drawbars setup the sound for the lower manual channel. Two brown drawbars  
(called 16’ and 5 1/3’ in organ parlance) provide the sub-octave tone for a  
powerful sound. The white drawbars (8’, 4’, 2’ and 1’) mix in the pure octave  
harmonics. The black drawbars (2 2/3’, 1 3/5’ and 1 1/3’) provide extra timbral  
coloration. The combination of these tones allows a huge range of different  
sounds to be created. As with the pedal drawbars, the current preset is always  
represented with the drawbars.  
Upper Manual Drawbars  
9 drawbars control the upper manual, as with the lower manual. In total, three  
different sounds are always available – the pedal, lower and upper drawbar  
settings. Again, there is the possibility to get the B4 to act even more like  
the original B3 organ. On the Setup View you can activate the Perc disables  
1’ Drawbar feature. The stock B3 has nine contacts for every key, acting on  
the tonewheels behind the 9 drawbars. When the Percussion effect (see  
below) is active, one of those contacts has to be sacrificed, rendering the 1’  
drawbar inactive.  
Percussion Switches  
The four switches on the top-right hand side of the front panel control the  
use of the Percussion “effect”.  
The Percussion switch activates a circuit which amplifies one of the upper  
drawbars and lets it decay over time. The result is a highly characteristic  
sound that is indispensable for jazz and many other styles.  
58 – B4 II  
 
When activating Percussion on an original B3, the 1’ tone becomes silent.  
The default setting for the B4 does not account for this. You can, however,  
activate the Perc disables 1’ drawbar feature on the Setup View to get your  
B4 act like the original in this aspect.  
The speed of decay and the percussion volume can be adjusted in the Expert  
View. As an enhancement over the original B3, the B4 allows any drawbar to  
be selected as the source for the percussion tone. The percussion effect is  
only available on the upper manual.  
The Percussion Volume switch toggles between two preset volume levels (Soft  
and Normal) for the Percussion sound. This switch will override the setting of  
the Volume dial sitting on the Expert View.  
On similar grounds, the Percussion Decay switch toggles between two preset  
decay speeds for the Percussion effect, overriding the preset setting.  
Using the Percussion Harmonics switch you can choose between two different  
drawbars producing the Percussion effect. Again, you will override the preset  
value on the Expert View that has more than two settings to choose from.  
On the lower-right of the B4 Manual View you will find two additional  
Knobs:  
With the Reverb dial you can set the amount of reverb signal getting mixed  
into the output signal.  
The Drive knob can be found both on the Manual View and on the Organ View  
in the tube amp section. You can use it to set the overdrive amount of the  
built in tube-amplifier model. This control provides a wide range of settings,  
be it clean jazz, bluesy crunch or downright heavy rock distortion. Be sure to  
check the Organ View for a selection of different authentic cabinet models  
that complement the overdrive sound.  
B4 II – 59  
 
Bank Switch  
This rotary switch selects one of 10 banks of presets. Ready for immediate  
use, there are all the popular sounds for jazz, rock and classical play, as well  
as some more extreme settings. A change to the bank selection will cause an  
immediate change to the preset in use (and the drawbar, effects and Rotator  
settings displayed).  
Each bank holds 12 presets, one on each Preset Selector key.  
Upper Preset Selectors  
Just like on the original organs, these 12 inverse colored keys are used  
to select presets. However, the presets now provide complete recall for all  
settings affecting the organ drawbars, Tube Amplifier and Rotator. Unlike the  
B3, there is no “cancel” preset – all presets implement actual stored settings,  
and the drawbars reflect the current tone settings. As discussed earlier, the  
Upper Preset Selectors control the setting of all B4 manuals – upper, lower  
and pedal.  
Lower Preset Selectors  
These 12 inverse colored keys can be used to recall alternative drawbar  
settings for the lower manual and bass pedals. Again, there is no “cancel”  
preset – all presets implement actual stored settings.  
60 – B4 II  
 
Rotator Controls  
The rotating speaker simulation (Rotator) speeds up and slows down realistically  
when operating this switch (which responds to the MIDI Mod-Wheel control).  
The rotation speeds and acceleration characteristics can be adjusted with  
complete flexibility in the Expert View.  
The Rotator effect can also be disabled for straight organ sounds by using the  
rotor brake. When switching the brake to Stop you will hear that it does not  
simply switch the effect, but that the rotor decelerates down to a complete  
halt. Switching to Run accelerates the rotor back to speed.  
The best way to use the Rotator features is having two footswitches – one for  
switching the speed and one for the brake.  
Note: The first generation Leslie cabinets did not have the brake feature.  
It was later introduced and became a much used feature.  
Expression Pedal  
The Expression Pedal (or Swell Pedal) is used to dynamically vary the  
instrument’s volume for expressive playing.  
Note: The Expression Pedal setting is not saved with presets – it is a  
performance control only.  
B4 II – 61  
 
Organ View Controls  
The Organ View Panel…  
The Organ view is split into several sections: Organ, Tube Amp, Microphones,  
the cabinets selector, and an overview of the Manual View settings (reviewed  
above). The Organ section sets details in the tone generation model. In the  
Tube Amp section you can control the tone of the Amplifier model and the  
Microphone section deals, well, with microphone details.  
For extra fine control while working with knob or slider positions, hold down the  
Shift key while clicking on a control. This will increase the mouse movement  
needed to move the selected control.  
Apart from the Manual view the Organ view is the one you will probably spend  
most of the time on. It displays the most commonly used controls for shaping  
your organ sound.  
Organ Controls  
62 – B4 II  
 
Keyclick amount adds an initial bite to the sound that is a popular part of the  
tonewheel sound. The “bite” provided by higher keyclick volumes will add  
definition to the organ tone (especially good for soloing), and is useful when  
the B4 needs to cut through a dense mix.  
The original B3 is not velocity sensitive. With the B4, however, you can add  
variable velocity sensitivity by turning the Velocity knob. This is a nice feature  
to play accentuated riffs and can greatly enhance your organ voice.  
The Leakage parameter simulates a crosstalk between the tonewheel outputs.  
As the value increases, the separation of the different tonewheels will decrease,  
resulting in a wider frequency range of the produced tone. This simulates an  
ageing effect. Tonewheels tend to get leaky and dolfed in badly maintained  
B3 organs over the years. Use it to your advantage when the sound has to  
be a bit trashy.  
The Sustain knob in the Pedal Bass section provides control over the volume  
envelope of the bass pedal sounds. If turned completely to the left, the bass  
pedal notes sound only as long as the incoming MIDI note signals dictate. The  
further the knob is turned to the right, the longer the notes will sound even  
after the key/pedal has been released. If you are using a MIDI pedal controller  
you can use this as a playing aid for held notes.  
The String/Organ switch changes the decay characteristics of the bass sustain  
function. In String mode it acts like a plucked bass string, sloping the volume  
to zero after a key is pressed. In Organ mode the volume is held at full volume  
for the complete hold phase.  
Tube Amp Settings and Indicators  
The Tube Amp Overdrive Indicator Tube provides feedback as to the amount  
of overdrive produced by the tube amp model. As overdrive is increased, the  
depicted tube will glow brighter.  
Tube Amp Drive determines the preamp level sent to the main tube amp model.  
At high levels, this will force the tube amp into overdrive, and can add a beefy  
Rock sound to the organ.  
B4 II – 63  
 
The Tube Amp Volume sets the output level sent from the amplifier model.  
This determines the overall volume of the organ, and is used to provide volume  
compensation between presets. This is strictly a volume adjustment, and has  
no effect on the tone of the amp.  
The Bass and Treble knobs control two shelving equalizers helping to shape  
the sound of the amp.  
Tube Amp Bass boosts or cuts the bass frequency range and can give amplifier  
distortion a fuller sound.  
The Tube Amp Treble setting affects the high frequency tones sent through  
the amplifier. This can be used to reduce the high frequencies of the output  
sound, and create a more mellow output from the B4.  
Cabinet Settings  
The last part of the Tube Amp controls is the Cabinets panel. Here you choose  
the different cabinet models available as a tonal addition to your organ sound.  
Below are descriptions with some comments concerning sound character.  
Please use the comments as only rough guidelines. Most of the cabinet  
models can be very variable in sound depending on the settings of other B4  
parameters. Feel free to experiment.  
Rotator 122 Open: This cabinet has an open, direct sound and is well-suited  
for everything rock.  
Rotator 122 Closed: If you are looking for that typical jazz flavor, use this  
cabinet.  
Rotator 147 Open: This one also provides very nice jazz tones. The microphones  
are placed off-axis in this model and the sound is a bit softer than with the  
closed 122 model.  
Rotator 147 Closed: Yet another setting similar to the Rotator 122 closed.  
Again, the microphones are placed off-axis and the sound character is more  
on the soft side.  
64 – B4 II  
 
Citrus: This setting simulates an on-axis condenser microphone on a guitar  
cabinet and represents a well-balanced all-around tone.  
Tweedman: An on-axis dynamic microphone picking up a 4 x 10 guitar box. It  
is nice for a jazzy sound with pleasant bass tones. Think Jimmy Smith.  
Jazz: If you are looking for that dirty Jimmy McGriff sound, this cabinet  
can come close. It simulates a 2 x 12 speaker setup with a condenser  
microphone.  
Twang: This can sound soft and warm. A nice cabinet for ballad work, sporting  
an on-axis condenser microphone and a model of a well-known 2 x 12 guitar  
rig.  
AC Box: A British sounding guitar setup using both a dynamic and a condenser  
microphone. Farfisa and Continental tonewheels are welcome!  
Plexi: Another British sound from the sixties. This is a 4 x 12 with an on-  
axis dynamic microphone and an additional off- axis condenser. Can you say  
“Heavy Rock”?  
Lead 800: This setup is similar to the Plexi setting, only more on the modern  
side. You will get increased presence with a more aggressive sound.  
Bass-VT: This is a simulation of a famous bass guitar setup. It can sound very  
beefy and sports a horn speaker for some extra presence.  
Direct: With the direct setting the cabinet is replaced by a D.I. box. It simulates  
plugging the rotator output directly into the mixing desk.  
Microphone Settings  
The output of the Rotator is “picked up” by pairs of virtual microphones  
– models of physical microphones that can accurately reflect the real-world  
output of the Rotator.  
The Rotator control balances the mix between the rotor signal and the Amp/  
Cabinet output without rotor. Use this knob to determine how strong the rotor  
sound is present in your signal.  
B4 II – 65  
 
The Balance control determines the relative mix between the treble and bass  
speaker outputs. This provides control of the tonal characteristics of the  
speaker output (and, therefore, the entire plug-in).  
When turned all the way to the right you hear only the treble rotor. Fully left  
and only the bass rotor is heard. With the knob centered you get an even mix  
of the two rotors.  
The Pan control can place the treble to one side and bass to the other side of  
the stereo output. In the extreme positions, one side will be pure bass and the  
other pure treble. Center is neutral, with both treble and bass going equally  
to both stereo channel.  
Operation of Balance and Pan controls.  
Finally, the Air control adjusts the level of early reflections in the room response  
of the B4 microphone model. Use this if you are looking for a relatively “roomy”  
and a bit more indirect sound character.  
66 – B4 II  
 
Expert View Controls  
Advanced controls on the Expert view…  
The Expert View also displays the regular performance controls on the lower  
part of the screen. However it is more geared for programming sounds.  
Tonewheel  
The B4 goes beyond what is possible with an old Hammond organ in many  
ways. One important feature is that it is equipped with a replaceable tonewheel  
generator as standard. This means you can easily take out the whole set of  
91 tonewheels and replace them with a new set. In this way you can quickly  
change the basic sound of the organ.  
In the old days, if you weren’t happy with the sound quality of your Hammond  
organ, for example because the tones weren’t pure any more, you had to get a  
specialist to replace the filter capacitors in the tonewheel generator and calibrate  
the tone filter circuits. With the B4, you can quickly switch between different  
tonewheels by selecting a set from the menu - it activates instantly.  
B4 II – 67  
 
Just like the old tonewheel organs, the B4 has no master tune control because  
tonewheels run at a fixed synchronous speed that cannot be changed. The  
only way to change the master tuning is to change the transmission ratios in  
the tonewheel generator, something that’s completely impractical in hardware  
but easily achieved with the B4’s replaceable tonewheel generator. You can  
now choose the B3 Classic Tonewheel Set in different tunings. The B3 classic  
set is in standard 440Hz tuning. You can also choose the tunings 436Hz,  
444Hz, 448Hz and 452Hz.  
Another important aspect of musical instruments is age. The filter capacitor in  
Hammond tonewheel generators deteriorate with age, which leads to an increase  
in leakage and rattle in the basic tone sound. To simulate organs with different  
degrees of ageing there are Sets with varying amounts of purity or dirt.

great bands of the sixties and seventies, such as The Doors and The Animals.  
Another well-known manufacturer is Farfisa, known through Pink Floyd, Can,  
Tangerine Dream, or Stereolab.  
With your B4 you also have three Continental tonewheel sets, two Farfisa sets  
68 – B4 II  
 
and a Harmonium simulation right at your fingertips.  
Percussion  
The Percussion Volume control determines the amount of percussion effect  
in the sound. The use of percussion provides a lightness to the sound, and  
is particularly useful for jazz and house organ sounds. Percussion Volume  
has only two positions on the B3: “Soft” and “Normal”. On the B4, this is  
continuously variable over a wide range. The position corresponding to the  
B3 setting “Soft” is labeled S and “Normal” is labeled N.  
Note: When setting Percussion to the “Normal” volume on a stock B3,  
the overall volume of the upper manual drops. This is regarded as a  
drawback by most players and is not reproduced on the B4.  
The Percussion Decay control determines the speed at which the percussive  
sound decays. Percussion Decay only has two positions on the B3: “Fast”  
and “Slow”. On the B4, this is continuously variable through a wide range.  
The position corresponding to the B3 setting “Fast” setting is labeled F and  
“Slow” is labeled S.  
Percussion Harmonic controls the drawbar used for the percussion tone.  
This control has 9 steps representing the 9 harmonic drawbars available  
for percussion generation. The Percussion Harmonic Selector has only two  
positions on the classic B3: “Second” (4’) and “Third” (2 2/3’). On the B4  
any of the 9 Drawbars can be used as the source for the percussion sound.  
The positions corresponding to the B3 settings are labeled 2 and 3.  
Note: Just like on the B3, the B4 percussion effect is single-triggered,  
meaning that it only starts with the first key pressed and does not  
retrigger with any notes played legato. Only after all upper manual keys  
are released will percussion trigger again. B3 players know how to take  
advantage of this in their playing technique.  
B4 II – 69  
 
Vibrato  
The Vibrato Mix control determines the type of effect. This is continuously  
variable from Vibrato (Mix knob right) through Chorus (Mix knob centered) to  
almost no effect (Mix knob left).  
The Vibrato Depth control determines the amount of vibrato applied to the  
sound.  
Note: The Vibrato And Chorus knob on the Manual View (as with the  
original B3) allows only Vibrato or Chorus effect to be selected (at depth  
settings of 1, 2 or 3). The B4 implements continuous controls to provide  
more subtle use of the vibrato and chorus effects.  
Reverb  
The Reverb section provides control over the room simulation of your B4.  
First of all, you can switch between a Studio and a Spring reverb. The Studio  
reverb has a clean and smooth character, while the spring reverb is modeled  
after the classic reverbs used in guitar amplifiers. Both settings can produce  
lush and harsh sounding reverb effects. Simply experiment to find settings  
that fit your style.  
The Time dial is your main control for the reverb time. It spans a wide range  
of decay times from a few hundred milliseconds up to several seconds.  
The Size parameter sets the dimensions of the simulated room. For the Studio  
reverb higher settings increase the pre-delay of the reverb algorithm. With the  
spring reverb a higher size value equals a longer spring.  
The Reverb gets its signal from the tube amplifier. With the Pre/Post you can  
control how much of it is being fed into the cabinet and how much goes into  
70 – B4 II  
 
the signal chain after the Rotator. Have a look at the following diagram to get  
a better understanding of the reverb signal flow.  
Reverb Signal Flow…  
Rotator Controls  
B4 II – 71  
 
Treble Rotor  
The indicator lamp provides visual feedback of the current treble rotation  
rate.  
The Slow speed sets the rotational speed of the treble rotor when the Rotator  
Speed switch is set to Slow. This setting is continuously variable between 0  
and 85 rpm. When the knob is centered you get a typical chorale effect.  
The Fast speed setting determines the speed of the treble rotor when the  
Rotator Speed switch is set to Fast. This setting is variable from 85 to 700  
rpm. When the knob is centered you get a typical tremolo effect.  
The Accel control sets the rate of change (acceleration or deceleration) when  
the Rotator Speed switch is changed. The range of this setting is 0.1 to 20  
seconds.  
The Spread setting determines the difference between the left and right  
microphone signals by moving the microphones apart a certain distance. This  
provides a perceived “width” or stereo spread when the Rotator is spinning.  
With Spread at minimum, both mics are in the same place. As Spread is  
increased they move around the speaker cabinet in a circle, but in opposite  
directions. With Spread at maximum they are at opposite sides.  
Bass Rotor  
These control work exactly like the Treble Rotor controls but this time they  
affect the bass rotor.  
The Single/Dual switch offers the possibility to have 2 Rotators running in a  
stereo setting. A single Leslie cabinet is already stereo per se, but sometimes  
more is better. With the Dual setup you get 2 complete Rotators spinning  
in opposite directions and with slightly different speeds for that extra wide  
sound.  
Finally, the Distance control sets the apparent distance between the microphones  
and the rotors. This affects the “amplitude modulation” of the mic’d sound  
(the change in volume as the rotor horn passes the microphone). When the  
microphones are at a small distance there is a lot of amplitude modulation,  
making the sound pulsate.  
72 – B4 II  
 
Operation of Spread and Distance controls.  
B4 II – 73  
Drawbar Programming Basics  
Theory  
The key to understanding drawbar programming is to understand the use of  
harmonics. Harmonics are the basis of complex sound generation, and are  
present in almost every sound you hear.  
The most basic sound is the pure sine wave. It consists of the “fundamental”  
tone only. The fundamental is the base frequency of a pitch. For example, the  
frequency of the A above middle C is 440 Hz.  
The sound of a pure sine wave is not very interesting (although it can be used  
for deep bass sounds). We can make the basic sound more interesting by  
adding “harmonics” – frequencies that are related to the fundamental tone.  
The “first” harmonic is a tone one octave above the fundamental. By mixing  
some of this first harmonic with the fundamental, we get a brighter and more  
complex sound.  
Harmonics can be manipulated in two different ways: either by starting with  
a simple tone and adding harmonics (additive synthesis), or by starting with  
a complex sound and removing harmonics (subtractive synthesis). Most  
synthesizers use subtractive synthesis to create sounds, but the B4 (and any  
real tonewheel organ) uses additive synthesis to create its sound. This is one  
of the reasons that tonewheel organs have a very different sound from their  
synthesizer cousins.  
There is a series of harmonics (called the natural harmonics) that are related  
to the fundamental in a specific way. These harmonics, if mixed together, will  
describe something like a sawtooth wave (a moderately buzzy sound). The  
natural harmonics of middle C, for example, are:  
The first 8 harmonics of Middle C  
74 – B4 II  
 
It would be convenient if tonewheel organs used harmonics to describe the  
drawbars settings. However, the terms used for describing the harmonic content  
of organs historically comes from pipe organs, where the use of various lengths  
of pipe determines the tonal characteristics. Hence, organs have come to use  
“pipe length” rather than harmonic number to describe sound settings.  
Additionally, it is quite useful to have tones that are not part of the basic  
harmonics series to “fatten up” the resultant sound. On the tonewheel organ,  
the brown drawbars provide tones which are not natural harmonics of the  
fundamental frequency, but belong to the harmonic series starting one octave  
below. That’s why they are often called sub-harmonics.  
The “pipe length” settings, and their relationship to the natural harmonics,  
are described in the following graphic:  
Drawbars and their Harmonics  
B4 II – 75  
 
Practice  
Now that we’ve reviewed the technical and historical aspects of the tonewheel  
organ, let’s use this information to create some useful sounds with the B4.  
We will use the upper manual to experiment with the organ sound, although  
all of the following concepts will work equally well with the other manuals.  
The only exception is pedalboard programming, as the drawbars provided for  
the bass pedals are missing the highest three drawbars.  
Let’s start with a very basic setting. Select the Manual view, and turn off all of  
the effects (the Percussion, Rotator and Vibration switches, and the Drive dial).  
This will allow us to hear the pure tone generation without any interference.  
Now, “push in” all of the drawbars, and pull out the 8’ bar (which is the  
fundamental tone). You can now hear the pure frequency of a note.  
The white programming drawbars provide octaves above the fundamental tone.  
If you pull out the white bars, you will hear tones one (4’), two (2’) and three  
(1’) octaves above the basic tone. Notice how the drawbars act like a mixer,  
allowing you to add the harmonics tones to the output sound.  
The first brown drawbar (16’) will also give an octave sound, but below the  
fundamental tone. Using the octave drawbars alone, and especially the higher  
octaves (2’ and 1’), you can produce “cheesy organ” sounds popular with  
60’s and 70’s bubblegum pop, and also useful for adding a bit of humor to  
modern dance mixes. The following setting is a good example of a typical  
cheese organ sound:  
76 – B4 II  
 
Now, let’s work with some of the other harmonics. Again, reset the drawbars  
with only the 8’ bar pulled out. Then start adding tones using the black  
drawbars. Notice how the sound becomes more “angular”, and there is less  
of a pure tone nature to the sound. In fact, you can even eliminate the 8’  
drawbar, and only hear the high harmonics. Since there is no fundamental  
in the produced tone, the note is only “implied”. By varying the amount of  
fundamental, you can get a variety of standard jazzy organ sounds.  
Now, for some more useful settings! Here is a patch that is often used by  
rock organists:  
Note that the lower tones carry the entire weight of the sound. This gives  
a very ballsy sound, and reinforces the bass in a typical rock combo. Dial  
in a bit of overdrive to add the grungy sound of an overdriven tube amp to  
complete the sound.  
Church organists and “soap opera” stylists will use a fuller range of drawbars.  
This can give the illusion of a great pipe organ, especially when combined with  
the Rotator. Turn on the Rotator, set the speed to Slow, and use the following  
patch to create the Days of Your Life...  
B4 II – 77  
Both jazz organists and house producers tend to use similar drawbar setting  
– primarily using lower drawbars with just a touch of higher harmonics, and  
the addition of the percussion sound. The difference in use is based on  
details: jazz cats will make a significant number of changes to the Rotator  
while playing, while a house player will typically leave the Rotator at the slow  
setting (using the organ sound as a grooving pad). A jazzer will breathe life  
into the performance by pumping the expression pedal, but in house music  
Velocity Sensitivity is used for accenting the groove.  
The following settings will give you one (of an infinite number) of settings  
used in this genre:  
Finally, let’s look at a drawbar setting that will be useful for pulling off rock  
solos. In addition to the rock pad sound listed above, we will want to add  
both percussion and keyclick sounds. The percussion sound is added using  
the Perc. switch, but the keyclick has to be added using the Keyclick control  
on the Organ View. Turn up the level of Keyclick, and you will hear a bite at  
the attack of each note. This, combined with the percussion and a slight bit  
of overdrive will give you a sound that will bite its way through any mix.  
The above tips are just a start. The tonewheel organ system has been in use  
for several decades, and players are still finding new settings, techniques and  
effects combinations for their sound. Experiment, try “impossible” settings  
and fully exercise the B4’s capabilities. You will find that the seemingly simple  
B4 interface can be used in an incredible number of musical applications.

B4 II – 81  
Genres:  
Jazz  
Well-known artists: Jimmy Smith, Jimmy Mc Griff, Barbara Dennerlein, Funk  
Brothers, Brother Jack Mc Duff...  
Jazz was the first contemporary musical genre using the Hammond in a  
completely new context. Laurens Hammond originally presented his organ  
as a portable and affordable replacement for the church organ. Thus, it got  
introduced into the gospel music of the black community and finally into  
jazz!  
Rock  
Well-known artists: Procul Harum, Keith Emerson, Rick Wakeman,  
Stevie Winwood...  
The guitarists were having fun with more and more powerful amps. Therefore  
the keyboard folks had to look around for something louder then a piano: the  
Hammond!  
Soul/R+B/Funk  
Well-known artists: Booker T. and the MG’s(Stax), The Funk Brothers (Motown),  
James Brown, Prince, Sly and the Family Stone...  
Black music embraced the Hammond right from the start.  
House  
Well-known artists: The KLF, Armand van Helden, David Morales  
The classic house organ sound was produced by cheesy preset boxes ((Casio CZ-  
101, Yamaha DX-21 etc.). Now it finds its way back into the virtual original!  
Please switch velocity on for house music.  
Hi Gain  
Well-known artists: Deep Purple, Uriah Heep, Spooky Tooth...  
The second guitar of Smoke on the Water“ was no guitar but a Hammond  
organ played through a Marshall amp! Play harder, play louder!!  
Reaggae  
Well-known artists: Toots and the Maytals, The Wailers, Desmond Dekker,  
Peter Tosh  
82 – B4 II  
The Hammond can already be heard on the legendary Studio 1 recordings,  
from the times when reaggae still was called ska.  
Transistor  
Well-known artists: Pink Floyd, The Doors, Can, Iron Butterfly…  
At that time a Hammond/Leslie combo was as expensive as a family car. But  
there were alternatives: transistor organs made by Vox, Farfisa and others. The  
above mentioned bands helped these organs to gain a psychedelic underground  
reputation.  
Indian Harmonium  
Well-known artists: Nitin Sawhney, Panjabi MC, Nusrat Fateh Ali Khan,  
The Harmonium has a big role in Indian music. You can hear it all over the place  
from classical Raga music to modern Bollywood/Bhangra productions.
