INTRODUCTION  
AlesisMIDIVERB III  
16 BIT MULTI-EFFECTS PROCESSOR WITH REAL-TIME MIDI PARAMETER CONTROL  
INTRODUCTION  
The Alesis MIDIVERB III is a high quality multi-effects unit which  
features up to 4 simultaneous effects (Delay, Reverb, Chorus, EQ) at a  
full 15KHz bandwidth and with 16 bit resolution.  
Since all features of MIDIVERB III are accessible from the front panel,  
the operator can set up a wide range of complex effects without a  
complex user interface.  
The MIDIVERB III features 200 on-board memory locations, of which the  
first 100 (000 to 099) are factory pre-programmed with a variety of  
programs. Memory locations 100 to 199 contain the same programs as  
the first 100 so that the user can modify or erase these locations without  
loosing any of the factory programs. All of the second 100 programs can  
be edited and stored by the user as desired. The original 100 factory  
programs (000 to 099) cannot be altered permanently.  
The rear panel consists of five 1/4" jacks (left and right inputs and  
outputs, bypass), MIDI input and output jacks, and a power supply  
connector. The unit can also be rack mounted in a single 19" rack  
space.  
FEATURES  
Full 15KHz signal bandwidth for greater fidelity  
True 16 bit resolution for quieter performance  
200 memory locations consisting of 100 factory and 100 user

INTRODUCTION  
HOW TO USE THIS MANUAL  
Since a musician's time is better spent making music than reading manuals, we've  
tried to make this manual not only easy to use, but also fast and easy to find things  
when you need to. Therefore, the manual is broken down to 6 major sections, of  
which Section 4 will be probably be referred to the most. They are:  
SECTION 1 - QUICKSTART  
This section tells you how to use the most frequently needed operations. If you have  
to use your MIDIVERB III now but don't have the time to read the entire manual,  
Section 1 will quickly guide you through.  
SECTION 2 - DESCRIPTION OF CONTROLS  
This section gives a brief explanation of all front panel and rear panel controls and  
indicators.  
SECTION 3 - INTERFACING MIDIVERB III  
Section 3 deals with the interfacing of MIDIVERB III to another MIDI device or into a  
MIDI system.  
SECTION 4 - USING MIDIVERB III  
Section 4 gives an overview of the software functions and pages of MIDIVERB III. This section will probably  
be the most used part of the manual as it describes how to execute every function in a  
step by step manner. Actual display readouts of MIDIVERB III are also included.  
SECTION 5 - SPECIFICATIONS  
Section 5 provides the operational specifications for MIDIVERB III .

The next two buttons control what is known as MIDI program MAPPING,  
which means that a MIDI program change number can be mapped to  
select any of the MIDIVERB III's programs. For example, without MIDI  
program MAPPING, selecting MIDI program 23 from an external MIDI  
device would select program 23 on the MIDIVERB III. With MIDI  
MAPPING, selecting MIDI program 23 on an external MIDI device could  
be set to select any program on the MIDIVERB III.  
The MIDI MAPPING functions are global functions and are not stored  
with an individual program.  
MIDI PROG/9  
INT. PROG/0  
Part of the MIDI program MAPPING section when in the EDIT mode, the  
MIDI PROGram button selects a MIDI program number from 000 through  
127 that will be received by the MIDIVERB III from an external MIDI  
controller.

SECTION 3  
INTERFACING MIDIVERB III  
INSTRUMENTS  
MICROPHONES  
The Alesis MIDIVERB III has high impedance inputs that are ideally  
suited for use either with instruments or line level signals. Although  
microphones can be connected directly into the MIDIVERB III, it is  
recommended that for quietest operation they be connected to a mixing  
console first and then connected to the MIDIVERB III as described in  
Figures 2 or 3.  
MONO OPERATION  
For mono operation of the MIDIVERB III, use only the Right Input. This  
will result in a stereo output. If a mono output is required, only the Right  
Output should be used. See Figures 1A and 1B

MIXING CONSOLES  
INTERFACING VIA AUX SENDS  
The MIDIVERB III handles mono or stereo sends at all system levels.  
The input circuitry of the MIDIVERB III can easily handle +4dBv levels  
(+20dBv peaks), while having enough input or output gain to interface  
with the extremely low signal levels of budget recording systems.  
The MIDIVERB III may be connected to the mixing console in several  
ways. It can be used to effect several instruments at once by using the  
auxiliary send and return controls of the console. Simply connect an  
aux send of the mixing console to the Right Input of the MIDIVERB III  
(or 2 aux sends connected to both left and right of the MIDIVERB III for  
stereo) and then connect the output of the MIDIVERB III back to either  
the aux returns or input channels. See Figure 2

SECTION 3  
CONNECTION TO THE MAIN OUTPUTS  
Still another way of interfacing the MIDIVERB III to a mixer or recording  
console would be in-line across the output of your mixing console (See  
Figure 4).  
This setup would be used only if you needed to effect the entire mix.

SETUP  
After you have connected your MIDIVERB III to either an instrument or  
mixing console:  
1) Turn the INPUT LEVEL control up until the green SIGNAL LED  
Indicator lights (It's OK if the red Clip LED occasionally lights,  
but distortion will result if it remains on constantly).

INTERFACING MIDIVERB III  
2) Now turn the OUTPUT LEVEL control up (clockwise) until there is  
sufficient level at the amplifier or mixer. Be careful not to turn  
the OUTPUT LEVEL control up too high since the strong signal  
may cause your amplifier or mixer to overload.  
3) Next, turn the MIX control until the correct balance between  
effect and direct signal is reached.  
PLEASE NOTE:  
For  
optimum signal-to-noise ratio (quietest operation), it is always best to have the INPUT  
LEVEL control turned up as high as possible, but not so much that the Clip LED lights.

SECTION 4  
USING MIDIVERB III  
PROGRAM MODE  
When power is first turned on, the MIDIVERB III automatically resets to  
the Program mode and the last program selected before the power was  
turned off will be currently selected.  
For the purpose of illustration, let's assume that you are turning your  
MIDIVERB III on for the first time. The MIDIVERB III's front panel should  
look like this:  
000  
In the Program mode when initially powered up, note that the front panel  
will display the following:  
A) The PROGRAM LED will be lit, indicating that the MIDIVERB III is in the  
Program mode.  
B) The display will read the program number, in this case "000".  
SELECTING A PROGRAM  
There are three ways to select a program on the MIDIVERB III when it is  
in the Program mode; by using the VALUE buttons, by using the ten keys  
on the right of the front panel which function as a keypad in the Program  
mode, or by receiving a MIDI program change (when Program Change  
has been enabled).  
WITH VALUE BUTTONS  
If we desire to select program 023, for example, we could simply press  
and hold the "up" VALUE button until program 023 was displayed. At that  
point, the MIDIVERB III's front panel would look like this:  
22  
Download from Www.Somanuals.com. All Manuals Search And Download.  
USING MIDIVERB III  
023  
Note that the front panel still displays the following:  
The PROGRAM LED will be lit, indicating that the MIDIVERB III is in the  
Program mode.  
The display will read the program number, only now it reads "023".  
WITH KEYPAD  
Another way to select program 23 would be to use the ten function keys  
on the right of the front panel which double as a keypad in the Program  
mode (notice the numbers beside each button). To do this we would do  
the following:  
1) Select the three digits (all programs must have 3 digits) from  
the keypad. In this case 0 (INT. PROG button), 2 (DELAY  
button), 3 (CHORUS button).  
The program will be selected after the third digit is entered.  
2) The three digits must be selected within 4 seconds or the  
program will revert back to the previous program number.  
023  
After the third digit is entered, the display will read as above.  
FROM MIDI  
The third and final way to select program 23 is with a program change  
command received via MIDI.  
1) Enable MIDI Program Change by first pressing the EDIT button.  
2) Press the MIDI button until the display reads "Pof" or "Pon".  
23

SECTION 4  
Pon  
3) Press the "Up" VALUE button until display read "Pon"  
4) Set program 023 on the MIDIVERB III to correspond with the  
desired program number on your synth, sequencer, or other  
MIDI device. (see " How to Use MIDI Mapping" on page  
xxxxxxx).  
5) Send the program change from your synth, sequencer, or  
other MIDI device.  
EDITING A PROGRAM  
Any MIDIVERB III program can be easily edited (modified) by entering  
the EDIT mode. As an example, we will edit our program 023.

SECTION 4  
REVERB  
Reverb can be thought of as a great number of distinct echos, called  
reflections, that occur so fast that our ear hears them blurred together as  
one. In nature, different size spaces give distinctly different sounding  
reverbs, depending upon the size and shape of the space (called Reverb  
Density), and the texture of the surfaces that the reflections bounce off of  
(called Reverb Diffusion). The various parameters of the MIDIVERB III  
make it possible to simulate nearly any natural reverberant space that  
can be imagined, and a few artificial ones as well.  
The programmable parameters are:  
REVERB ALGORITHM  
There are 20 different Reverb Algorithms, or Reverb versions, in the  
MIDIVERB III. Each algorithm has a different sound and simulates a  
different acoustic environment. See Figure 5.

USING MIDIVERB III  
REVERB DECAY  
The Reverb Decay determines the length of time that the Reverb will  
sound before it finally fades away. It is not used in the Reverse 1 and 2  
Algorithms. It is functional in all others.  
DELAY  
The Delay section of the MIDIVERB III can be used in two modes,  
depending upon the configuration. In some configurations, the Delay  
acts as a straight mono Digital Delay which can be programmed for up to  
490 milliseconds. In other configurations that feature the Reverb of  
MIDIVERB III , it will be used as a Pre-Delay for the Reverb section with  
a maximum setting of up to 100 milliseconds.  
The programmable parameters are:  
DELAY TIME  
Delay Time is the amount of time between the original signal and the first  
repeat, or echo, of the signal.  
DELAY REGENERATION  
Delay Regeneration means that a portion of the delay signal output is  
"fed back" into the input, resulting in the delay repeating itself. The more  
regeneration, the more repeats.  
CHORUS  
The Chorus section of the MIDIVERB III is primarily used to slightly  
change the pitch of the signal fed into the unit. This is done to make the  
input signal thicker and bigger sounding.  
The programmable parameters are:  
CHORUS

SECTION 4  
There are 24 different Chorus Algorithms (Chorus versions), in the  
MIDIVERB III. Each algorithm has a different sound and simulates a  
different pitch based effect.  
There are two major types of algorithms: Chorus and Flanging (see  
explanation below). Both Chorus and Flanging have 6 algorithms of  
mono and 6 algorithms of stereo. See Figure 6.

WHAT IS CHORUS?  
As the name implies, the Chorus effect is used to make one instrument  
sound like two or more instruments played together. Just as a string  
section, with its tiny variations in tuning and timing, sounds thicker than a  
single violin, so does a guitar or keyboard sound bigger and more  
interesting when a bit of chorusing is applied.  
Mono Chorus is achieved by splitting the signal into two, then slightly  
delaying and detuning one of the parts. In Stereo Chorus, the signal on  
the left will detune in one direction while the signal on the right detunes in  
the other direction.  
WHAT IS FLANGING?  
First used in the sixties, "Flanging" was achieved by the use of two tape  
recorders that would record and play back the same program in  
synchronization. By alternately slowing down one tape machine, and  
then the other, different phase cancellations would occur. Since the  
slowing down of the tape machines was done by hand pressure against  
the flanges of the tape supply reels, the term "Flanging" came into being.  
Today, Flanging can be closely simulated by many outboard effects  
processors such as the MIDIVERB III. The effect of Flanging, either  
electronically or mechanically done, is achieved by splitting and slightly  
delaying one part of the signal, then varying the time delay, with an LFO  
(Low Frequency Oscillator). The delayed signal is then mixed back with  
the original signal to produce the "swishing" or "tunneling" sound. Many  
28

USING MIDIVERB III  
variables are available, from varying the Speed and Depth of the LFO to  
feeding back part of the signal to make the effect stronger.  
In the case of a Stereo Flange, the signal is split into three parts with a  
dry signal and a separate Delay section for both left and right channels  
with one channel flanging up while the other channel flanges down. This  
causes the effect to become more pronounced and dramatic.  
CHORUS SPEED  
Varying the Chorus Speed parameter affects the amount of signal  
detuning, and therefore the depth of chorusing while in the Chorus  
mode. When in the Flanging mode, Chorus Speed will affect the speed  
of the flange.  
EQ  
The EQ section of the MIDIVERB III is actually a single pole, 6dB per  
octave low pass filter, designed to roll off the high frequency response of  
either the input or effect in order to simulate the high frequency rolloff  
that occurs naturally in different environments. The number that is  
displayed is the frequency point where the signal has already rolled off -  
3dB. See Figure 7.  
When in the EDIT mode, pressing the EQ button will access either the  
INPUT EQ or EFFECT EQ, depending which EDIT LED is lit.

SECTION 4  
INPUT EQ  
The INPUT EQ is a high-cut filter that rolls off the high frequency  
response of the input signal before it is sent to either the Delay, Reverb,  
or Chorus. The VALUE button selects the frequency where the signal has  
been rolled off -3dB. See Figure 7.  
EFFECT EQ  
The EFFECT EQ is a high-cut filter that is part of the currently selected  
effect. The VALUE button selects the frequency where the signal has  
been rolled off -3dB. See Figure 7.  
With effects that have reverb (Configurations 1 through 13), the EFFECT  
EQ determines the high frequency decay of the reverb.  
With effects  
that have Delay (Configurations 14 and 15), the EFFECT EQ determines  
the frequency response of the Delay Regeneration (or the number of  
repeats).  
MIX PARAMETERS  
When in the EDIT mode, pressing the MIX button will adjust the relative  
level of either the Delay or Reverb, depending on which page the Edit  
LED is set. The programmable Mix Parameters are especially useful in  
live situations where the level of Delay and Reverb must be different  
from program to program.  
The Chorus level is always the same and is either On or Off depending  
upon the Configuration selected.  
The Mix parameters are:  
DELAY OUTPUT  
LEVEL  
The Delay Output Level adjusts the output level of the Delay section.  
REVERB OUTPUT  
LEVEL  
The Reverb Output Level adjusts the output level of the Reverb section.

USING MIDIVERB III  
MODULATING MIDIVERB III 's PARAMETERS  
MOD PARAMETERS  
The MOD section lets you control various MIDIVERB III parameters from  
a MIDI controller such as the pitchwheel, modwheel, keyboard  
aftertouch, keyboard note number, keyboard velocity, sustain pedal, or  
breath controller. This is extremely useful when dynamic or real-time  
control is required in a live playing situation, and allows for a new level of  
creativity on recordings.  
MOD ROUTING  
The Mod Routing parameter selects the MIDI controller which will  
remotely change (modulate) one of the parameters of the MIDIVERB III .  
There are eight common MIDI controllers that can be routed to control  
one of six possible MIDIVERB III parameters, making a total of 48  
possible routing combinations, plus an OFF position.  
MOD CONTROLLER SOURCES  
The Mod Controller options for the Mod Routing are:

DESCRIPTION  
PITCH BEND  
The pitch bend wheel or lever common on most synthesizers.  
The Mod Wheel common on most synthesizers is designated  
Controller #1 in the MIDI specification. It is called Controller #1  
instead of Mod Wheel here since it is easier to display as "1" due to  
the limits of the 7 segment LED displays.  
CONTROLLER #1  
AFTER TOUCH  
After a note is depressed, a pressure on the key will cause a MIDI  
command. This ability is not available on all keyboards.  
Any MIDI note from keyboard, sequencer, or drum machine.  
The target parameter will change in relation to how hard a key is  
struck.

MOD AMPLITUDE  
The Mod Amplitude is the amount that the selected MIDIVERB III  
parameter will be affected by the Mod Source. It can be adjusted to  
affect the target parameter by a positive or negative amount. In other  
words, if the Reverb Decay was selected as the Mod Destination with the  
pitch wheel of a keyboard as the Mod Source, the pitch wheel could be  
programmed to cause the Reverb to increase the decay (positive) or  
decrease its decay (negative).  
The VALUE button selects the amount of Modulation.  
CONFIGURATIONS  
At the heart of MIDIVERB III's unique sophistication is its 15 different  
configurations. A configuration is the order in which the internal digital  
Effects are placed. Even with all 4 effects operating simultaneously,  
each effect suffers no sonic degradation, and is capable of full 16Hz to  
15KHz bandwidth.  
CONFIGURATION SIGNAL  
PATHS  
One of the major differences between each configuration is whether the Chorus of the  
MIDIVERB III is connected directly to the output, or if it is fed directly into the Delay or  
Reverb instead. Figure 10 shows that Configurations 1 through 6 are identical with  
Configurations 7 through 12 except that 1 through 6 has the Chorus connected to the  
output.  
Another major difference between configurations is how the Delay section of the  
MIDIVERB III will be used. In Configurations 1, 7, and 13, the Delay is used for slightly  
delaying the Reverb in order to simulate a larger environment. This is called PreDelay.  
In all other configurations, the Delay section functions as a normal digital delay. See  
Figure 10.

SECTION 4  
USING MIDIVERB III WITH MIDI  
MIDI PARAMETERS  
The MIDI button accesses the various MIDI parameters of MIDIVERB III.  
The MIDI functions are global functions and are not stored with an  
individual program.  
MIDI CHANNEL  
The MIDIVERB III can receive MIDI information on channels 1 through  
16. When in the EDIT mode, the MIDI button is used to select the send  
and receive channel for the MIDIVERB III. The range is 01 through 16.  
The MIDI functions are global functions and are not stored with an  
individual program.  
TO CHANGE MIDI CHANNELS  
1) When in the EDIT mode (either EDIT LED lit), press the MIDI  
button once. The numeric display will show "c01" for MIDI  
channel 01.  
c01  
2) If another MIDI channel is desired, press either VALUE button  
until the desired channel is displayed.  
c02

USING MIDIVERB III  
MIDI PROGRAM  
CHANGE  
Pressing the MIDI button a second time accesses the MIDI Program  
Change page which allows the MIDIVERB III to change programs  
remotely by a MIDI Program Change command. The MIDIVERB III will  
also send Program Change commands when programs are selected  
from the front panel. When used in conjunction with the VERB PROGRAM  
button, the MIDIVERB III transposes the program numbers of a MIDI  
controller (a synthesizer, for instance) to match those of the MIDIVERB  
III .  
SELECTING MIDI PROGRAM CHANGE  
1) When in the EDIT mode ( either EDIT LED lit), press the MIDI  
button TWO times. The numeric display will read "Pon" if MIDI  
Program Change is on, and "Pof" if MIDI Program Change is  
off.  
Pof  
2) Press the VALUE "Up" button to toggle MIDI Program Change  
"On"; Press the VALUE "Down"button to toggle MIDI Program  
Change "Off".  
Pon  
MIDI ECHO  
Pressing the MIDI button a third time accesses the MIDI Echo page which  
allows any MIDI information received by the MIDIVERB III (with the

exception of System Exclusive data) to be retransmitted back out the  
MIDI OUT jack.

USING MIDIVERB III  
SELECTING MIDI ECHO  
1) While still in the EDIT mode ( either EDIT LED lit), press the  
MIDI button THREE times. The numeric display will read "Eon"  
if MIDI Echo is on, and "Eof" if MIDI Echo is off.  
Eof  
2) Press the VALUE "Up" button to toggle MIDI Echo "On"; Press  
the VALUE "Down"button to toggle MIDI Program Change "Off".  
Eon  
MIDI SEND  
Pressing the MIDI button a fourth time accesses the Send MIDI page,  
which makes it possible to save all MIDIVERB III programs externally to  
a MIDI storage device (such as an Alesis DATADISK) or swap programs  
with another MIDIVERB III via MIDI system exclusive. System Exclusive  
is a distinct software protocol specific to the MIDIVERB III. This makes it  
possible to do such things as MIDI Data Dumps and retrievals, as well as  
communication via external computer.  
TRANSMITTING PROGRAMS VIA MIDI  
1) While in the EDIT mode ( either EDIT LED lit), press the MIDI  
button FOUR times. The numeric display will read "Snd" to  
indicate that MIDI Send is enabled.  
Snd

SECTION 4  
2) Press the STORE button, which causes MIDIVERB III's entire  
memory to be sent out via MIDI to an external storage device  
like an Alesis DATADISK or another MIDIVERB III. The  
display will read "____" while sending the data, which will take  
about 1 second, after which it will return to "Snd".  
---  
RECEIVING PROGRAMS VIA MIDI  
1) At any time, the MIDIVERB III can receive MIDI Program Data  
(known as a Sysex dump). The display will read "____" while  
receiving the MIDI data, which will take about 10 seconds due  
to the time required to store 100 programs.  
---  
MIDI MAPPING  
The next two buttons control what is known as MIDI program MAPPING,  
which means that a single MIDI program number can be programmed to  
select any of the MIDIVERB III's programs. For example, without MIDI  
program MAPPING, selecting MIDI program 23 from an external MIDI  
device would select program 23 on the MIDIVERB III. With MIDI  
MAPPING, selecting MIDI program 23 on an external MIDI device could  
select any program on the MIDIVERB III.  
The MIDI MAPPING functions are global functions and are not stored  
with an individual program.  
For example, if the following program changes were desired:  
MIDI Controller Program 101 = MIDIVERB III Program 33  
50  
Download from Www.Somanuals.com. All Manuals Search And Download.  
USING MIDIVERB III  
MIDI Controller Program 102 = MIDIVERB III Program 39  
MIDI Controller Program 103 = MIDIVERB III Program 25  
Selecting program 101 on the MIDI controller would result in program 33  
of the MIDIVERB III being accessed, selecting program 102 would result  
in program 39 of the MIDIVERB III being accessed, and selecting  
program 103 would result in program 25 of the MIDIVERB III being  
accessed.  
MIDI PROG  
INT. PROG  
Half of the MIDI MAPPING section, the MIDI PROGram button selects an  
external MIDI program number from 000 through 127 that will be  
received by the MIDIVERB III from a remote MIDI controller.  
The other half of the MIDI MAPPING section, the INT. PROG (Internal  
Program) button selects the internal MIDIVERB III program (from 000 to  
199) that will be chosen by the external MIDI program number selected  
by the MIDI PROG button.  
HOW TO USE MIDI MAPPING  
A single MIDI program change number from an external MIDI controller  
or sequencer can be programmed to select any of the MIDIVERB III's  
programs through MIDI program MAPPING. For example, without MIDI  
Mapping, selecting MIDI program 23 from an external MIDI device would  
select program 23 on the MIDIVERB III. With MIDI program MAPPING,  
selecting MIDI program 23 on an external MIDI device could select any  
program on the MIDIVERB III.  
If we desired to have program 100 on our MIDI controller select program  
33 on our MIDIVERB III, and program 101 on our MIDI controller select  
program 65 on our MIDIVERB III, then we would do the following:  
1) While in the EDIT mode ( either EDIT LED lit), select the MIDI  
PROG button on the MIDIVERB III.  
2) Press the VALUE button until the desired program number of  
the external MIDI controller is displayed. In this case it would  
be program 100.

3) Select the INT. PROGRAM button on the MIDIVERB III.  
4) Press the VALUE button until the desired internal MIDIVERB III  
program number is displayed. In this case it would be program  
33.  
033  
5) Select the MIDI PROGRAM button on the MIDIVERB III once  
again.  
6) Press the VALUE button until the next desired program number  
of the external MIDI controller is displayed. In this case it  
would be program 101.  
101  
7) Select the INT. PROGRAM button on the MIDIVERB III once  
again.  
8) Press the VALUE button until the desired internal MIDIVERB III  
program number is displayed. In this case it would be program  
65.  
065  
9) Continue steps 1 through 4 as many times as MIDI program  
MAPPING is necessary.

MISCELLANEOUS FUNCTIONS  
INITIALIZING THE MIDIVERB III  
There are two reasons why you may want to reinitialize your  
MIDIVERB III :  
1) To return all programs to their factory parameter settings (called  
"initializing").  
2) In case the unit locks up from a power surge.  
To initialize your MIDIVERB III, do the following:  
1) Turn the MIDIVERB III off.  
2) Hold the INT. PROG and STORE buttons.  
3) Turn the MIDIVERB III on again while holding the above  
buttons.  
---  
PLEASE NOTE:  
This procedure will erase all user stored parameters and return all  
MIDIVERB III parameters to their default values.  
The MIDI program table will return to 000 through 199.  
Programs 100 through 199 will become duplicates of factory  
programs 000 through 099.  
The display will be blank for about ten seconds while the memory is  
initialized.  
CAUTION: This procedure will erase all user programs from memory!!
