Your First Session with the MicroVerb 4 – Chapter 1  
CHAPTER 1  
YOUR FIRST SESSION WITH THE  
MICROVERB 4  
Unpacking and Inspection  
Your MicroVerb 4 was packed carefully at the factory, and the shipping carton was  
designed to protect the unit during shipping. Please retain this container in the highly  
unlikely event that you need to return the MicroVerb 4 for servicing.  
The shipping carton should contain the following items:  
This instruction manual  
Alesis MicroVerb 4 with the same serial number as shown on shipping carton  
AC Power Supply Adapter  
Alesis warranty card  
It is important to register your purchase; if you have not already filled out your  
warranty card and mailed it back to Alesis, please take the time to do so now.  
Basic Connections  
The MicroVerb 4 is designed to accommodate a number of applications, whether you  
are connecting an instrument directly into it, or connecting it with a mixing console.  
Briefly described here are the basic connections to get you up and running quickly.  
For more information on connections, please refer to Chapter 2.  
Mono In, Mono or Stereo Out. Connect a mono cord to the [LEFT/MONO]  
INPUT of the MicroVerb 4 from a mono source. (The Left input will then feed both  
inputs.) Connect another mono cord from the [LEFT] OUTPUT of the MicroVerb 4  
to an amplification system or mixer input. Additionally, you could connect a  
second mono cord to the [RIGHT] OUTPUT for use with a stereo amplification  
system, or two mixer inputs.  
Stereo. Connect two mono cords to the [LEFT/MONO] & [RIGHT] INPUTS of the  
MicroVerb 4 from a stereo source , and two mono cords from the [LEFT/MONO]  
& [RIGHT] OUTPUTS of the MicroVerb 4 to a stereo amplification system or two  
mixer inputs.

Chapter 1 – Your First Session with the MicroVerb 4  
¿ Before turning on the MicroVerb 4’s power, check the following items:  
Have all connections been made correctly?  
Are the volume controls of the amplifier or mixer turned down?  
¡
Plug in the power adapter and insert the Power jack into the [POWER] input on  
the rear panel of the MicroVerb 4.  
Upon power-up, the display will briefly illuminate all front panel LEDs, display the  
Software version, and then display the last selected Program Number (00–199 ).  
¬
Turn on the power of the amplifier/mixer, and adjust the volume.  
Setting Levels  
Proper setting of the input and output levels is crucial in order to achieve the  
maximum signal-to-noise ratio. As a good rule of thumb, it is always best to set both  
input and output level controls at 3/4 or 75% of full. This will decrease the possibility  
of overload distortion and keep the amount of background noise to a minimum.  
If the Input Meters on the MicroVerb 4 begin to clip (go into the red), turn down the  
Input level or decrease the volume of the source (instrument, mixer send, etc.). If the  
MicroVerb 4’s level is causing the mixer or amp to distort, turn the Output Level  
down.

The MicroVerb 4’s Front Panel contains the following:  
¨
Input. The Input level control sets the level going into the MicroVerb 4. This  
should be adjusted so that the input meters (÷) read approximately -6dBu (3 of  
the 4 LEDs lit up). It controls both the Left and Right Input levels simultaneously.  
¡
Mix. The Mix control adjusts the balance between the direct signal coming into  
the input and the effects generated by the MicroVerb 4.  
¬
Output. The Output level control sets the level going to the amplifier or mixer  
from the MicroVerb 4.  
÷
Level Meters. The Level meters display the signal level coming into the Input.  
There are actually 2 meters, one for the left and right inputs, but both will light up  
for a mono input.  
ƒ
LED Display. The LED display typically shows the currently selected Program. It  
can also display the MicroVerb 4’s MIDI channel (when the MIDI button is held  
down) or parameter values (when the [EDIT A] or [EDIT B] knobs are adjusted).

Chapter 1 – Your First Session with the MicroVerb 4  
Auditioning Internal Programs  
The MicroVerb 4 comes with 100 Programs in a Preset bank, plus another 100  
Programs in the User bank. These Programs represent the wide range of applications  
for which the MicroVerb 4 is suited. The difference between Preset and User  
Programs is that User Programs can be replaced with your own edits, but Preset  
Programs are permanently stored into memory.  
To audition the internal effect Programs, turn the [VALUE] knob to scroll through the  
100 Preset and 100 User Programs.  
Switching Between Preset and User Banks  
To instantly switch between the Preset and User banks, press the [BANK] button.  
Each time you press the [BANK] button, the MicroVerb 4 will toggle back and forth  
between the Preset and User banks. The display will indicate this by showing a  
program in the 00-99 (Preset) range or the 100-199 (User) range.  
You can also switch between banks when scrolling through the Programs with the  
[VALUE] knob. When you scroll clockwise past Preset 99, the display will “roll-over”  
to User 100. Likewise, if you turn back the [VALUE] knob counterclockwise past  
User100, the display will move to Preset 99. However, if you turn back the [VALUE]  
knob counterclockwise past Preset 00, the display will not wrap around back to User  
199 but instead will remain at Preset 00.  
Adjusting Effects Mix Levels  
Whether a Program contains a single effect or two or three effects, you can adjust the  
MicroVerb 4’s [MIX] control to obtain a desirable balance between the original,  
uneffected signal and each effect’s output. The [MIX] Knob controls the balance  
between the input signal and the effects generated by the MicroVerb 4.  
When hooked up to an instrument setup, such as a guitar amp, the Mix setting will  
typically be somewhere in the middle, balancing the effects with the sound of the  
source instrument. If the MicroVerb 4 is connected to a mixing console’s Aux Send,  
the Mix control should be set all the way to the right (effects only) so that the balance  
can be controlled from the board.

Your First Session with the MicroVerb 4 – Chapter 1  
Storing Edited Programs  
Once you are satisfied with the changes you have made to an edited Program, or are  
creating a new Program from scratch, you will need to store your edited Program  
back into memory. The MicroVerb 4 will temporarily store the currently selected  
Program in non-volatile memory. If you edit a Program, the changes you made will be  
lost the next time you power on the unit if you haven’t stored the edited Program into  
memory. If you select another Program from memory before storing the edited  
Program, your changes will also be lost.  
Although the MicroVerb 4 has two banks (Preset and User), you can only store  
Programs in the User bank.  
To store an edited Program:  
¿ Press [STORE].  
The Destination Program Number will flash. If the edited Program is from the  
Preset bank (Programs 00-99), the MicroVerb 4 will show the complement  
Program in the User Bank (by adding 100 to the Program number.) Programs  
can only be stored to the location provided, i.e. there is no way to store an edited  
version of Program 112 over Program 113.  
¡
Press [STORE] again.  
The LED Display will momentarily flash quickly, indicating that the Program has  
been stored.  
Any changes you make to a Program are temporary, until you store those changes  
into memory. If the Program you are editing is in the Preset bank, you must save the  
changes you’ve made to a location in the User bank. If you recall another Program  
before storing,  
your changes will be lost.  
Bypassing Effects  
At any time you can bypass the effects, thereby allowing the direct signal to pass  
through the MicroVerb 4 unchanged. This can be done in two ways:  
by turning the MIX knob all the way to the left,  
by connecting a footswitch to the [FOOTSWITCH] jack and pressing the  
footswitch.  
Each time the footswitch connected to the [FOOTSWITCH] jack is pressed, Bypass  
mode is toggled on and off again. For more information about Footswitches, see  
Chapter 2.

Connections – Chapter 2  
CHAPTER 2  
CONNECTIONS  
AC Power Hookup  
The MicroVerb 4 comes with a power adapter suitable for the voltage of the country it  
is shipped to (either 110 or 220V, 50 or 60 Hz).  
With the MicroVerb 4 off, plug the small end of the power adapter cord into MicroVerb  
4’s [POWER] socket and the male (plug) end into a source of AC power. It’s good  
practice to not plug in the MicroVerb 4 until all other cables are hooked up.  
Alesis cannot be responsible for problems caused by using the MicroVerb 4 or any  
associated equipment with improper AC wiring.  
Line Conditioners and Protectors  
Although the MicroVerb 4 is designed to tolerate typical voltage variations, in today’s  
world the voltage coming from the AC line may contain spikes or transients that can  
possibly stress your gear and, over time, cause a failure. There are three main ways  
to protect against this, listed in ascending order of cost and complexity:  
Line spike/surge protectors. Relatively inexpensive, these are designed to protect  
against strong surges and spikes, acting somewhat like fuses in that they need to  
be replaced if they’ve been hit by an extremely strong spike.  
Line filters. These generally combine spike/surge protection with filters that  
remove some line noise (dimmer hash, transients from other appliances, etc.).  
Uninterruptible power supply (UPS). This is the most sophisticated option. A UPS  
provides power even if the AC power line fails completely. Intended for computer  
applications, a UPS allows you to complete an orderly shutdown of a computer  
system in the event of a power outage, and the isolation it provides from the  
power line minimizes all forms of interference—spikes, noise, etc.  
Audio Connections  
The connections between the MicroVerb 4 and your studio are your music’s lifeline,  
so use only high quality cables. These should be low-capacitance shielded cables  
with a stranded (not solid) internal conductor and a low-resistance shield. Although  
quality cables cost more, they do make a difference. Route cables to the MicroVerb 4  
correctly by observing the following precautions:  
Do not bundle audio cables with AC power cords.  
Avoid running audio cables near sources of electromagnetic interference such as  
transformers, monitors, computers, etc.  
Never unplug a cable by pulling on the wire itself. Always unplug by firmly  
grasping the body of the plug and pulling directly outward.  
Do not place cables where they can be stepped on. Stepping on a cable may not  
cause immediate damage, but it can compress the insulation between the center  
conductor and shield (degrading performance), or reduce the cable’s reliability.  
Avoid twisting the cable or having it make sharp, right angle turns.

Chapter 2 – Connections  
Although Alesis does not endorse any specific product, chemicals such as Tweek  
and Cramolin, when applied to electrical connectors, are claimed to improve the  
electrical contact between connectors.  
Typical Applications  
The analog audio inputs and outputs are typically used in one of three ways:  
from one or two effect/aux send outputs of a mixer, and out to the effect return  
inputs of the mixer; or,  
from a line-level instrument (like a guitar or keyboard with either a mono or stereo  
output), and out to an amplifier or mixer input; or,  
from the stereo buss outputs of a mixer to a mix-down tape machine or amplifier.  
When used with a mono source, the MicroVerb 4 is placed between the source and  
the mixer/amplifier. Although the source may be mono, both the [LEFT/MONO] and  
[RIGHT] outputs can be connected to the inputs of a mixer/amplifier if stereo  
processing effects are desired. If using the effect sends of a mixer, you have the  
advantage of sending any of the mixer’s input channels to the MicroVerb 4’s input(s),  
and have control over the level of each channel being sent.  
These applications are outlined and illustrated in detail on the following pages.  
Input Jack Wiring  
The MicroVerb 4’s [LEFT] INPUT jack is normalled to the [RIGHT] INPUT. This  
means that if you only connect a single mono cable to the [LEFT] INPUT jack, it will  
also be routed to the [RIGHT] INPUT. However, if anything is connected to the  
[RIGHT] INPUT jack, this normalized connection will be broken; therefore the [LEFT]  
INPUT jack feeds only the [LEFT] INPUT, and the [RIGHT] INPUT jack feeds only the  
[RIGHT] INPUT. Also, the [RIGHT] INPUT jack is NOT normalled to the [LEFT]  
INPUT.

Interfacing Directly with Instruments  
When connecting audio cables and/or turning power on and off, make sure that all  
devices in your system are turned off and the volume controls are turned down.

The MicroVerb 4 has two 1/4” unbalanced inputs and two 1/4” unbalanced outputs.  
These provide three different audio hookup options:

Chapter 2 – Connections  
Interfacing to a Mixing Console  
The MicroVerb 4 handles mono or stereo sends at all system levels. The input  
circuitry of the MicroVerb 4 can easily handle +4 dBu levels (+20 dBu peaks), while  
having enough input and output gain to interface with the low -10 dBV signal levels of  
budget recording systems.  
The MicroVerb 4 may be connected to a mixing console in several different ways. It  
can be used to effect several instruments at once by using the auxiliary send and  
return controls of the mixer. Another method of interfacing is to connect the unit  
directly to the insert send and return patch points of the channel that is to be effected.  
Still another way of interfacing the MicroVerb 4 to a mixer or recording console would  
be in-line across the output of your mixing console. This last setup would be used  
only if you wanted effects on the entire mix.  
Using Aux Sends  
Generally, mixing consoles provide two types of auxiliary sends: pre-fader sends for  
creating a cue (headphone) mix, and individual, post-fader effect sends. Typically, if a  
mixer has more than two sends per channel (4, 6 or 8, perhaps), the first two sends  
are reserved for the cue sends, while the remaining sends are used to feed effects,  
such as the MicroVerb 4. If you are using a mixer with more than two sends, connect  
the MicroVerb 4 using post-fader sends.  
Using a mixer’s aux sends poses a distinct advantage: each channel has its own  
level control feeding the aux output (and eventually the MicroVerb 4 input). This  
allows you to make a mix of any channels you want to go to the effects by using the  
individual channels’ aux send levels on the mixer. Most consoles also have aux  
master controls, which set the overall level of each aux output.  
Coming back from the MicroVerb 4’s outputs into the mixer, you have two options:  
connecting to dedicated return inputs, or  
connecting to channel inputs.  
The former is good if your mixer provides dedicated inputs (called returns) for effect  
devices like the MicroVerb 4. If your mixer does not have these, or you have already  
used them all, consider connecting the MicroVerb 4 to channel inputs (if there are any  
remaining). This method gives you the added bonus of more panning options and EQ  
on the effects.  
No matter where you connect the output of the MicroVerb 4 into the mixer, you are in  
control of the balance between the mixer’s channel inputs (the uneffected signal  
being routed to the aux sends and the Mix), and the effect returns coming from the  
MicroVerb 4. The effect returns generally should only contain effected signal, and not  
have any uneffected signal mixed with it (since these two signals are blended  
together at the mixer). Therefore, it may be necessary to modify the mix so that only  
effected signal is present at the MicroVerb 4’s outputs. To do this, turn the Mix control  
all the way to the right.

Connections – Chapter 2  
Mono In - Stereo Out. If you only want to feed the MicroVerb 4 a mono input, but  
wish to connect both of its outputs back to the mixer, you will need three 1/4" audio  
cables. Connect a mono cord from an effect send to the [LEFT] input of the  
MicroVerb 4, another mono cord from the [LEFT] output of the MicroVerb 4 to an  
effect return or other mixer input, and another mono cord from the [RIGHT] output of  
the MicroVerb 4 to an adjacent effect return or mixer input.

Stereo In - Stereo Out. This connection is similar to the one described above.  
However, by utilizing two sends from the mixer, we add one more cord and can now  
send a stereo signal to the MicroVerb 4’s inputs. For example, if you connected  
sends 3 and 4 to the [LEFT] and [RIGHT] inputs, and had a stereo instrument (such

left and hard right), you would send the left channel to send 3 and the right channel to  
send 4. This is especially useful on the Dual Send Programs, #90-99 and 190-199.

Chapter 2 – Connections  
By using individual channel inserts, you can dedicate the MicroVerb 4 to a specific  
channel (or pair of channels) on the mixer. The Insert connections on the back of the  
mixer provide a way of “inserting” external processing equipment into the signal path.  
The insert occurs after the input amplifier, and before the main fader; essentially it is  
the same as connecting the source (instrument or microphone) into the MicroVerb 4  
before the mixer’s channel input. However, some mixing console’s inserts come after  
the EQ section, and may therefore be different from the original signal. If nothing is  
connected to the channel’s Insert jack, the signal is not routed there.  
Usually, insert connections require a special, stereo-splitting Y-cord to be connected  
(one stereo plug provides both send and return while two mono plugs connect  
separately to the effects unit’s input and output). These are known as TRS connectors  
(tip-ring-sleeve). The tip of the stereo plug carries the send or output of the insert jack,  
while the ring carries back the return. The sleeve represents a common ground for both  
signals.  
Mono. This involves connecting a 1/4" TRS (tip-ring-sleeve) Y-cable to the Insert jack  
of a single channel on a mixing console. The other end of the cable (which splits into  
two, 1/4" mono connectors) are connected to the [LEFT] input and [LEFT] output,  
respectively. If you do not hear any audio after making these connections, swap the  
input and output cables at the MicroVerb 4, as these may be wired backwards. If the  
cable is color-coded, usually the red jack represents the send (which connects to the  
MicroVerb 4’s input) and black is the return (which connects to the output).

Avoiding Ground Loops  
In today’s studio, where it seems every piece of equipment has complex routing and  
computer logic, there are many opportunities for ground loop problems to occur.  
These show up as hums, buzzes or sometimes radio reception and can occur if a  
piece of equipment “sees” two or more different paths to ground. While there are  
methods to virtually eliminate ground loops and stray radio frequency interference,  
most of the professional methods are expensive and involve installing a separate  
power source just for the sound system. Here are some easy helpful hints that a  
professional studio installer might use to keep those stray hums and buzzes to a  
minimum.  
¿ KEEP ALL ELECTRONICS OF THE SOUND SYSTEM ON THE SAME AC  
ELECTRICAL CIRCUIT. Most stray hums and buzzes happen as a result of  
different parts of the sound system being plugged into outlets of different AC  
circuits. If any noise generating devices such as air conditioners, refrigerators,  
neon lights, etc., are already plugged into one of these circuits, you then have a  
perfect condition for stray buzzes. Since most electronic devices of a sound  
system don’t require a lot of current (except for power amplifiers), it’s usually safe  
to run a multi-outlet box or two from a SINGLE wall outlet and plug in all of the  
components of your system there.  
¡
KEEP AUDIO WIRING AS FAR AWAY FROM AC WIRING AS POSSIBLE. Many  
hums come from audio cabling being too near AC wiring. If a hum occurs, try  
moving the audio wiring around to see if the hum ceases or diminishes. If it’s not  
possible to separate the audio and AC wiring in some instances, make sure that  
the audio wires don’t run parallel to any AC wire (they should only cross at right  
angles, if possible).  
¬
TO ELIMINATE HUM IF THE ABOVE HAS FAILED:  
A) Disconnect the power from all outboard devices and tape machines except  
for the mixer and control room monitor power amp.  
B) Plug in each tape machine and outboard effects device one at a time. If  
possible, flip the polarity of the plug of each device (turn it around in the  
socket) until the quietest position is found.  
C) Make sure that all of the audio cables are in good working order. Cables with  
a detached ground wire will cause a very loud hum!!  
D) Keep all cables as short as possible, especially in unbalanced circuits.  
If the basic experiments don’t uncover the source of the problem, consult your dealer  
or technician trained in proper studio grounding techniques. In some cases, a “star  
grounding” scheme must be used, with the mixer at the center of the star providing  
the shield ground on telescoping shields, which do NOT connect to the chassis  
ground of other equipment in the system.

Connections – Chapter 2  
MIDI  
MIDI (Musical Instrument Digital Interface) is an internationally-accepted protocol that  
allows musical-related data to be conveyed from one device to another. The MIDI  
connections on the MicroVerb 4 provide four different functions:  
To recall Programs using MIDI program change messages  
To control (modulate) parameters inside the MicroVerb 4 in realtime via MIDI  
controllers (example: A keyboard’s mod wheel, or pedals, etc.)  
To send and receive SysEx (System Exclusive) dumps of individual programs or  
the entire bank of programs for storage and retrieval purposes  
To pass-on MIDI information thru the MicroVerb 4 to another MIDI device.  
To connect the MicroVerb 4’s MIDI ports to another MIDI device:  
¿ Connect a MIDI cable from the MicroVerb 4’s MIDI [IN] connector to the other  
MIDI device’s MIDI OUT connector.  
¡
Connect another MIDI cable from the MicroVerb 4’s MIDI [OUT/THRU] connector  
to the MIDI IN connector of the other MIDI device.  
Note: It is not necessary to follow step 2 if you intend to only send information to the  
MicroVerb 4, and do not need to receive information back from it. Example: If you  
only want to be able to recall Programs using MIDI program change messages, there  
is no need to connect a cable to the MicroVerb 4’s [OUT/THRU] connector. For more  
information about MIDI and Modulation, refer to chapter 5.  
Footswitch  
On the rear panel you will find a footswitch jack labeled [FOOTSWITCH]. This is a  
Stereo jack, with connections for both a normal Bypass jack and for two footswitch  
jacks. All footswitches must be plugged in before the MicroVerb 4 has its power  
turned on.  
To hook up a single Bypass Footswitch: Any momentary footswitch can be  
plugged into the Footswitch input on the MicroVerb 4. The extra connector on the  
footswitch jack will simply be ignored.  
To hook up two Footswitches: The MicroVerb 4 is equipped with a 1/4” TRS  
footswitch jack which can connect to two footswitch jacks. To connect both  
footswitches, first locate a cable or adapter which has one male 1/4” TRS jack and  
two female 1/4” mono jacks. This cable is available from several manufacturers, such  
as Radio Shack (#274-302) and Hosa (YPP-118).  
The footswitch connected to the tip of this jack will function as a Bypass pedal. The  
footswitch connected to the center ring of this jack will function as a Control pedal.  
(See below.) You may also use a dual footswitch, which has two pedals on one  
MicroVerb 4 Reference Manual

Chapter 2 – Connections  
assembly with a stereo cord already attached. The pedals are often packaged with  
digital pianos.  
You should not use the dual footswitch from a guitar amplifier, as these are typically  
latching type footswitches. You can tell a latching footswitch from an unlatched type  
when it takes two presses to enable any of the functions (Bypass, etc.). Also, these  
footswitches usually “click” when stepped on. Use only Momentary (non-latching)  
footswitches with the MicroVerb 4.  
If desired, a mono footswitch can be plugged half way (to the first “click”) to function  
as a Control Footswitch only.  
Bypass Footswitch . Pressing the footswitch will toggle Bypass mode on and off.  
When Bypass mode is activated, the effects will mute and the Display will read “bYP”  
and then dim. Bypass turns off any effects going to the output, and is useful for  
turning off delay for a certain part of a song, for example.  
Control Footswitch. When a footswitch is connected to the ring of the 3 connector  
Footswitch jack, it functions as a Control footswitch. This footswitch has 2 different  
functions, depending on the type of effect it is used on.  
On a Lezlie Effect: The control footswitch controls the Lezlie speed. When it is  
pressed, the display will either read ffFSt or SLO and the rotating speaker will  
ramp up to the Fast or down to the Slow speed, respectively.  
On a Delay Program: The Control footswitch acts as a “Tap Tempo” control.  
Tapping on the footswitch in tempo with the music will create a 1/4 note delay  
in tempo with the song. The display will briefly display the Delay Time (in  
milliseconds).  
When the selected Program is not a Lezlie or Delay Program, pressing the Control  
footswitch will have no effect.  
Tap From Audio. If the Control footswitch is held down and audio is played into the  
inputs, these impulses will be used to set the delay time. For example, hold down the  
Control footswitch on a delay program and play two staccato notes on a guitar,  
keyboard, etc. The delay time will be set for the time between these two sounds.  
Make sure that the level of these impulses are at least -6dB on the front panel meters  
(the third segment up) so that the MicroVerb 4 has sufficient level to trigger from.  
Tip: High notes work better than low notes when using this feature.

Overview of Effects – Chapter 3  
CHAPTER 3  
OVERVIEW OF EFFECTS  
Reverb Effects  
Reverb is made up of a large number of distinct echoes, called reflections. In a  
natural acoustic space, each reflection’s amplitude and brightness decays over time.  
This decaying action is influenced by the room size, the location of the sound source  
in the room, the hardness of the walls, and many other factors. The MicroVerb 4  
offers the following types of reverberation:  
Concert Hall (Programs 00-09, 100-109)  
This is a simulation of a large concert hall. Halls tend to be large rooms with lots of  
reflective surfaces, where sounds can swim around, changing timbre over time. This  
is a classic reverb which sounds good on just about anything. Try it on vocals, drums,  
acoustic, electric, or orchestral instruments.  
Real Room (Programs 10-19, 110-119)  
This algorithm gives you the sound of a medium size studio room. This algorithm  
uses a lot of processing power for a rich sound and smooth decay. It has a punchier,  
bigger sound than a Hall reverb, which makes it good for Rock and Dance music. The  
attack is also more reflective. It sounds good on drums, keyboards and guitars. This  
type also includes Nonlinear, Gated, and Reverse reverbs. for percussion and  
effects.  
Plate Reverb (Programs 20-29, 120-129)  
This is a simulation of a classic echo plate, a 4' by 8' suspended sheet of metal with  
transducers at either end used to produce reverb. Popular in the 1970’s, it still prized  
for its transparent sound, particularly on vocals and guitars. It works well for a lush  
lead vocal, piano, or guitar, especially when looking for a classic rock and roll sound.  
Reverb Parameters  
Decay (Edit A)  
The Reverb Decay determines how long the Reverb will sound before it dies away.  
Turning up the Reverb Decay will have the effect of increasing the rooms size.  
Generally, Classical, Jazz, and Ballad styles will use longer decay times than Up  
tempo Rock or Dance music. The LCD display will show the Decay time in Seconds  
and Milliseconds.  
Hi Cut (Edit B)  
The Hi Cut filter can be set between 059 Hz and 36.2 kHz or OFF, and attenuates all  
frequencies above this value by 6dB per octave. The lower the setting, the less high  
frequencies of the input are allowed to pass thru to the reverb effect. This controls the  
overall character of the room. Try a brighter sound on vocals, drums, and percussion,  
and a darker sound (i.e. lower Hi Cut frequency) on Acoustic Guitar, Piano, and  
Strings.  
Chorus/Flange Effects (Programs 30-49, 130-149)  
The Chorus and Flange effects alter the pitch and delay of a signal in various ways to  
produce “layered” timbres that are more complex than the original signal. Although  
MicroVerb 4 Reference Manual

Chapter 3 – Overview of Effects  
some of these effects can sound similar to one another depending on the parameter  
settings, each is achieved differently and can be quite dramatic under the right  
circumstances. Pitch effects are achieved by splitting the signal into at least two  
parts, effecting the pitch of one of the parts, then mixing them back together. This  
eventual mixing is essential since the overall sound of the effect is achieved by the  
difference between the dry, uneffected signal and the effects signal. Therefore, when  
using Chorus or Flange, it’s best to keep the Mix control around 50%. Also included  
in this bank is Auto Pan, which pans a mono signal from Left to Right. This type of  
effect works best with the Mix control set 100% wet. The various types of Chorus and  
Flange are:  
Stereo Chorus  
The Chorus effect is achieved by splitting the signal into three parts with a dry signal  
and a separate Detuning section for both left and right channels. The detuning is  
further effected by being modulated by an LFO (low frequency oscillator) which  
causes the detuning to vary. Many variables are available in this scheme: the  
Predelay can be varied, the LFO depth can be varied, the LFO speed can be varied,  
and a portion of the detuned signal can be fed back to the input to increase the effect.  
Finally, the waveform shape of the LFO can be changed from a smooth sine wave, to  
a more abrupt squarewave to make the pitch detuning more pronounced.  
Some of the MicroVerb 4’s Choruses have individual LFOs controlling the Left and  
Right sides, set at different rates. These effects, called True Stereo Choruses, often  
have a wider stereo image than regular Stereo Chorus effects. When the Rate is  
changed on a True Stereo Chorus, the frequency difference between the Left and  
Right sides is maintained. Note: These Choruses process the Left and Right sides  
individually, so any stereo imaging will be maintained.

Quad Chorus  
Quad Chorus modulates four delayed signals, each with its phase offset by 90. It  
gives you twice as much modulation effect as the Stereo Chorus, so it’s great for  
really fattening up a sound.

Overview of Effects – Chapter 3  
This is a less processor intensive version of the Stereo Chorus, used in Multi Effect  
configurations. The effect of Chorusing is achieved by splitting and slightly delaying  
one part of the signal, then varying the time delay with an LFO. The delayed signal is  
then mixed back with the original sound to produce a thicker, warmer sound.  
Stereo Flange  
First used in the 1960s, “flanging” was achieved by the use of two tape recorders that  
would record and play back the same program in synchronization. By slowing down  
one tape machine, and then letting it catch up with the other, different phase  
cancellations would occur at different frequencies. 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.  
Flanging is similar to chorusing , but modulates the delayed signal over a much  
shorter delay range (typically 0-12 ms). This produces a “jet airplane”-like sound. The  
flange modulation sweep can be triggered by the audio input (either the left or right  
input, or both), in order to sync up with the rhythm of your playing.  
In the case of the Stereo Flange, the signal is split into four parts with a stereo dry  
signal and a separate Delay section for both left and right channels with one channel  
flanging up while the other channel flanges down. Once again, this causes the effect  
to become more pronounced and dramatic. True Stereo Flanges have individual  
LFOs controlling the Left and Right sides for a wider stereo image.  
Some of the Flange Programs reset their LFO every time the input level passes a set  
threshold. These are called Triggered Flanges, and are useful for sweeping effects  
that move in time with the music or part. If the flange is retriggered in the middle of its  
sweep, this may cause a thumping or popping effect. This is not a malfunction of the  
MicroVerb 4. If you set the input volume properly ( retriggering will occur when the  
input signal crosses -6dBv on the input meters), the flanger will only retrigger for  
attacks and produce a smooth, sweeping sound.

Auto Pan  
The Auto Pan effect alternates the loudness of the signal in opposite channels at a  
definable rate. This effect may be triggered by the input signal (either the left or right  
input, or both). It can also be used for Tremolo effects, creating a fast panning effect  
for surf guitar. Edit A controls the speed of the panning effect and Edit B controls the  
width of the pan. When using the Auto Pan effect, the MicroVerb 4 should have its  
effects mix 100% wet with no direct signal mixed in to avoid phase problems.

Rate (Edit A)  
The Rate control sets the speed of the Chorus or Flanging sweep. When the Edit A  
knob is turned, the LCD display will show the edited sweep frequency in Hertz.  
Depth (Edit B)  
The Depth control sets the intensity of the Chorus or Flanger sweep. The LCD  
display will show the depth in a scale from 0 to 127 (0-125 for Flangers). Tip: Faster  
Choruses or Flangers typically sound better with a shallower depth than slower ones.  
Delay Effects (Programs 50-59, 150-159)  
Delay is a discrete echo repeat, unlike the rapid wash of repeats that create reverb  
effects. It is useful for adding depth to a track or performance if a reverb is muddying  
up the mix. There are several types of Delay in the delay bank:  
Mono Delay  
This subtype provides a delay of up to 1270 ms. The delay time can be adjusted  
separately by 10 millisecond increments. Feedback is also available to increase the  
number of delay repeats.  
Stereo Delay  
This Single Configuration provides two separate delays. Typically, the Edit A knob  
controls one side, and the other changes in proportion. The delay time can be  
adjusted separately by 5 ms increments.  
Ping Pong Delay  
So called because the output bounces from left to right in stereo with the speed  
determined by the delay time. The delay can be adjusted in 5 ms increments, and  
feedback is adjustable from 0-99%.  
MultiTap Delay  
This is like having three delays at once. They are usually arranged in a rhythmic  
delay pattern. The Edit A knob scales all of the delay times so that you can make the  
delay rhythm fit the tempo of a song.  
Delay Parameters  
Time (Edit A)  
This control sets the time between the input signal and the first delay tap. On the  
Multi Tap Delay and Stereo Delay programs, the Edit A knob will scale all of the  
delays by a percentage. The LCD display will show you the delay time in Seconds  
and Milliseconds, or (in the case of Multi Tap and Stereo Delays) percentage of the  
time scaling.  
Feedback (Edit B)  
After a signal has gone through the delay processing, it is fed back to the delay input.  
The Feedback control sets what percentage of the signal will go back through the  
delay. At a setting of 0%, no signal will go back through the delay, so only one delay  
26

Overview of Effects – Chapter 3  
tap will be heard. At a setting of 10%, only a little signal will be fed back through the  
delay, so the signal will repeat back a few times before fading into silence. At a  
Feedback setting of 100%, the signal will continue repeating for a few minutes before  
decaying into silence.  
Setting Delay Time Using Tap Tempo  
You can adjust the delay time using a technique called “tap tempo”. If you connect a  
footswitch to the ring of the Footswitch jack, it can be used as for Tap Tempo. (See  
Chapter 2, “Footswitch”, for connection instructions.) By tapping on the “Control”  
footswitch in tempo with the song, you can get a delay which repeats in time with the  
music.  
The MicroVerb 4 can also set its Delay Time by playing audio into the Inputs. To set  
the delay time using this method, hold down the Control Footswitch and play some  
quick notes into the MicroVerb 4. See Chapter 2, “Footswitch”, for details.  
Pitch Shifter Effects (Programs 60-69, 160-169)  
The Pitch shifter in the MicroVerb 4 takes the Pitch of the input signal and shifts it  
higher or lower by a fixed amount. Pitch shifters are useful for creating instant parallel  
harmonies and for creating subtle chorusing effects. The Pitch Shifters in the  
MicroVerb 4 include:  
Stereo Pitch Shifter  
The Pitch Shifter effect transposes the pitch of the incoming signal by a fixed amount.  
It is useful for creating parallel harmonies, detuning, chorusing, and special effects.  
The Semi (Edit A) parameter shifts the pitch in increments of one half step, with a  
range of up or down one octave. The Fine (Edit B) parameter detunes the signal in  
very fine increments, with a range of up or down one half step.  
Stereo Pitch Detuner  
The Pitch Detuner has a range of plus or minus one half step in increments on 1 cent.  
It is useful for a slight chorus effect or for Half step shifts. The Shift L (Edit A) and  
Shift R (Edit B) parameters control the shift of the Left or Right output.  
Multi Effects (Programs 70-89, 170-189)  
There are several Multieffect Programs in the MicroVerb 4. A multieffect can be  
simply described as 2 or three effects at once. This typically involves a pitch effect  
with reverb, such as Stereo Chorus into a Hall, or something more esoteric such as  
Lezlie into a room.

Lezlie  
With the Lezlie effect , the pitch change block becomes a rotating speaker simulator.  
This effect was extremely popular during the 1960’s and was achieved by  
mechanically rotating the speakers to produce complex timbral changes. The Lezlie  
speaker system is most often used with tone-wheel organs, but is occasionally used  
for guitar amplification as well. When changing the speed between fast and slow, the

effect will ramp rather than change abruptly, just as a true Lezlie speaker system  
would do.  
Multi Effects Parameters:  
Decay (Edit A)  
The Decay parameter controls the length of the Reverb. When adjusted, the LCD  
display will show the decay time in Seconds and Milliseconds.  
Rate/Time (Edit B)  
The Rate/Time parameter controls the rate of a Chorus or Flange, the Delay Time of  
a Delay, or the Motor Speed of a Lezlie, depending which is active in the Program. In  
the case where three effects are active at once, Chorus/Delay/Reverb for example,  
Edit B controls the Delay Time.  
Dual Send Effects (Programs 90-99, 190-199)  
The Dual Send programs all have two different effects. These effects are each fed by  
one of the inputs so that they can be used independently.

RIGHT OUTPUT  
This is an ideal setup for someone using the MicroVerb 4 with a mixer. By hooking  
two of the Aux Sends into the Left and Right inputs of the MicroVerb 4, you can use it  
to provide two discrete effects. Some of the multi effects include:  
Reverb/Delay  
The Left Input of the MicroVerb 4 feeds a Room reverb and the Right Input feeds a  
Mono Delay. The Edit A knob controls Reverb Decay (displayed in seconds) and the  
Edit B knob controls Delay time (also in seconds).  
Reverb/Chorus  
The Left input again feeds a Room reverb, and the Right side feeds a Stereo Chorus.  
The Edit A knob controls Decay time (in seconds) and the Edit B knob controls  
Chorus Rate (in Hertz). This Dual send Chorus has two individual LFOs panned hard  
left and hard right for a wide sound, and when the rate is changed the difference  
between the two rates will stay constant.  
Reverb/Flange  
The Left input again feeds a Room reverb and the Right input feeds a Stereo Flanger.  
Edit A controls the Reverb Time (in seconds) and Edit B controls the Flanger Rate (in  
Hertz).

Description of Controls – Chapter 4  
CHAPTER 4  
DESCRIPTION OF CONTROLS  
Front Panel  
Input Level  
The Input Level controls the level of the signal being fed into the MicroVerb 4. The  
MicroVerb 4 can operate with signal levels anywhere from +4dBv Pro Audio gear to  
guitar level signals. To set the input level, watch the Input Meters while adjusting the  
Input level (see below).  
Mix Level  
The Mix Level controls the balance between the uneffected signal coming through the  
inputs and the effects being generated by the MicroVerb 4. When the Mix is turned all  
the way to the left, the input signal will be sent straight to the output with no effects  
added. When the Mix is turned all the way to right, only the effects will be sent to the  
outputs with none of the original input signal mixed in. By keeping the Mix  
somewhere in the center, a blend of dry and wet signal can be achieved.  
With a typical instrument setup (use with a guitar amp, etc.) the Mix is usually set  
around 12 o’clock. When used with a mixing console, the Mix control should be  
turned all the way to the right (full wet) so that the effects mix can be controlled from  
the mixer.  
Output Level  
The Output Level controls the volume of the signal from the output of the MicroVerb  
4. The optimum level for this control is 75%, but it can be raised or lowered as  
necessary.  
Level Meters  
These peak-style meters monitor the signal strength of the unprocessed inputs, and  
are used in much the same way as the level meters on a standard tape recorder.  
Since the MicroVerb 4 is a True Stereo device, both the Left and Right inputs are  
shown separately as they may be performing different functions. When the red “Clip”  
LEDs are lit, the input signal may be distorted so the Input level should be backed off.  
If the bottom “-32dB” LEDs are barely coming on, the input signal is not high enough  
and the resulting sound from the MicroVerb 4 may be noisy. Ideally, the Input signal  
level should be set so that the input lights the first two or three LEDs.  
The “Clip” indicators may light up even if the signal level has not passed the -6dB  
level. If this happens, it means that the signal is clipping internally, probably on a  
regenerating program like a reverb or a flange with lots of feedback. If this happens  
simply back off the Input level until the problem goes away.  
LED Display  
When the MicroVerb 4 is first turned on, it will always cycle through a simple test  
mode. First, all LED segments in the display will light up. Then, it will display the  
software version installed (i.e. 1.00). Finally, it will return to the Program Number

which was last selected. (Note: When the MicroVerb 4’s power is disconnected, any  
edits to the currently selected Program will be lost.)  
The MicroVerb 4’s display is used to indicate the following:  
¿ Program Number. MicroVerb 4 Programs are numbered from 00 to 199.  
Programs 0-99 are Preset programs and 100-199 are User Programs. Unless  
some parameter on the MicroVerb 4 is being edited, the Program Number will  
always be displayed in its normal illumination. The only exception to this is when  
the MicroVerb 4 is bypassed with a footswitch; when the unit is bypassed the  
Program Number will be shown with the display dimmed.  
¡
MIDI Channel. When the [BANK/MIDI] button is held down, the Display will dim  
and the current MIDI Channel will be reported. The MIDI Channel can then be  
edited by turning the Value wheel while the Bank/MIDI button is held. Possible  
MIDI Channels are 00 (Omni), and 01-16.  
¬
Overwrite Program Number. When the [STORE] button is pressed, the Program  
about to be saved over will flash. Only User Programs can be Stored over, so if  
[STORE] is pressed while editing a Preset Program the MicroVerb 4 will add 100  
to the Program number for storage. When the Store button is pressed again to  
confirm, the Program number will flash rapidly and then return to the normal  
Program Number display.  
÷
Parameter Value. When the [EDIT A] or [EDIT B] knobs are turned, the LED  
display will dim and show the new value for that parameter. For example, when  
Edit A is adjusted on a Hall programs, the display will briefly show the new  
Reverb Time in seconds and milliseconds, then return to the Program number.  
STORE Button  
Either Preset or User Programs can be temporarily edited using the Edit A and Edit B  
knobs. If you wish to store these edits for later recall, press the [STORE] button. If  
you have edited a User Program, that Program number will start flashing. If you have  
edited a Preset Program, the complementary User Program number (that Program  
plus 100) will start flashing, since Presets cannot be saved over. This is the Program  
number which is about to be overwritten. By pressing the [STORE] button again, you  
tell the MicroVerb 4 to actually store the Program. The Program number will flash  
rapidly and then return to the normal Program Number display.  
BANK/MIDI Button  
This button serves three functions. To switch between the Preset Bank and the User  
bank, press and release the Bank button. The Program number will either increase or  
decrease by 100 as the unit switches banks. If the Bank/MIDI button is pressed and  
held for a moment, the current MIDI channel will be displayed. If the Value knob is  
turned while the Bank/MIDI button is being pressed, the MIDI channel can be  
adjusted. Finally, to dump the memory of the MicroVerb 4 to a sequencer or program  
librarian program, DataDisk, etc., hold the Bank/MIDI button until the MIDI channel is  
displayed and press [STORE]. The contents of the User bank will be sent to the MIDI  
output.  
VALUE Knob  
When no other button is being pressed, the Value Knob is used to change Programs.  
If the Bank/MIDI button is held while the Value Knob is being turned, the MicroVerb 4  
will change its MIDI channel.

Edit A/ Edit B Knobs  
The Edit A and Edit B knobs are used to adjust aspects of the currently selected  
Program. For example, on a Concert Hall program, the Edit A knob adjusts Reverb  
Decay Time and the Edit B knob adjusts Reverb Input Hi Cut. When the Edit A or Edit  
B knobs are adjusted, the new parameter registers briefly on the display.

Rear Panel  
Power  
This is a plug for connecting the Alesis Model P3 +9VAC power supply (supplied).  
The power supply is then connected to an AC outlet delivering a nominal 120VAC.  
The correct power supply must be used AT ALL TIMES. Any other power supply  
might create a fire risk and/or permanently damage your unit. This damage would  
NOT be covered under your warranty.  
Footswitch  
This is a 1/4" stereo phone jack which connects to one or two momentary (not  
latching) footswitches, either normally-open or normally-closed.  
When one footswitch is plugged into the Footswitch jack, it will function as a  
Bypass footswitch. When the Footswitch is pressed, the display will read “bYP”,  
the display will dim, and the MicroVerb 4 will stop producing effects. If the  
footswitch is pressed again, effects output will continue.  
Two footswitches can be connected if a simple adapter cable is used, similar to  
an Insert cable:  
When this setup is used, the footswitch connected to the Tip functions as a  
Bypass footswitch. The footswitch connected to the Ring functions as a Control  
footswitch. For more information, see Chapter 2, “Footswitch”.  
MIDI In  
This is a 5-pin DIN standard MIDI plug which connects to any MIDI compatible  
equipment such as a MIDI sequencer that will send program changes and controller  
information to the unit.  
MIDI Out/Thru  
This is a 5-pin DIN standard MIDI plug which connects to any MIDI compatible  
equipment such as a keyboard or another effects device. It is provided for sending  
system exclusive commands for storing programs. It also relays all messages  
received on the [MIDI IN].

These are 1/4" phone jacks which connect to sources such as the effects sends of  
mixing consoles. They may be used with nominal input levels from -10dBV (guitar  
level) to +4dBu. For mono applications, use the [LEFT/MONO] input.  
The [LEFT/MONO] input jack is normalled to the [RIGHT] jack. This means that when  
nothing is plugged into the [RIGHT] input jack, the signal present at the  
[LEFT/MONO] input is routed to the [RIGHT] as well.  
Output (Left & Right)  
These are 1/4" phone jacks which connect to devices such as the effects returns on a  
mixing console or Power Amplifier Inputs. For mono applications, use the [LEFT]  
output.

CHAPTER 5  
MIDI APPLICATIONS  
MIDI Functions  
The MicroVerb 4 provides many MIDI functions, including being able to respond to  
program changes, sending and receiving Program information via SysEx (System  
Exclusive) dumps, and realtime control over effect parameters via MIDI controllers.  
For more information about basic MIDI connections, see Chapter 2.  
MIDI Channel  
The MIDI Channel is used to receive program change messages, as well as other  
MIDI events for use with the realtime modulation capabilities in the MicroVerb 4.  
To set the MicroVerb 4’s MIDI channel:  
¿ Press and hold [BANK/MIDI].  
The Display will dim and display the current MIDI channel.  
¡
Turn the [VALUE] knob to set the MIDI Channel to either 01 through16, or 00 for  
Omni mode (receives on all 16 channels simultaneously).  
MIDI Thru  
The MicroVerb 4 automatically sends information from the MIDI IN to the MIDI  
OUT/THRU. In order to pass on MIDI information from a control device thru the  
MicroVerb 4 to another MIDI device, connect the control device’s MIDI OUT to the  
MicroVerb 4’s [MIDI IN]. Then connect the MicroVerb 4’s [MIDI OUT/THRU] to the  
MIDI IN of the other device you wish to control.  
If too much information is being sent thru the MicroVerb 4, the internal buffer may  
overflow. If this happens, the front panel will read FLO and some data going to the  
receiving unit may be lost. Alesis recommends that any dense MIDI information  
(SysEx, Midi Time Code, etc.) be routed directly to the receiving unit using a MIDI  
Patchbay instead of relying on the Thru port of the MicroVerb 4.  
Receiving Program Changes  
In order to recall programs on the MicroVerb 4 from a MIDI controller device :  
¿ Connect the control device’s MIDI OUT to the MicroVerb 4’s [MIDI IN].  
¡
Make sure that the MicroVerb 4 is set to the same MIDI Channel as the device  
that you are sending from (see above).  
Note: It is possible to select either the Preset or User bank via MIDI by sending a  
Controller 0 message immediately followed by a program change message. A  
Controller 0 with a value of 0 will select the Preset bank, while a value of 1 or higher  
(up to 127) will select the User bank. Any Program Change messages over 100 will  
be ignored.  
SYSEX Storage  
In order to send and receive Program information via Sysex (System Exclusive)  
dumps using a computer, or some other SysEx storage device, or another

Chapter 5 – Advanced Applications  
MicroVerb 4:  
¿ Connect the MicroVerb 4’s [MIDI OUT] to the receiving device’s MIDI IN.  
¡
Press and hold [BANK/MIDI] and press the [STORE] button.  
The display will read Sndas the User Programs are sent.  
¬
When you send a Sysex dump back to the MicroVerb 4, it will automatically go  
into receive mode (you do not have to do anything to the unit). When this occurs,  
the display will read rEc.  
Note: If an error occurs while receiving Sysex data back into the MicroVerb 4, the  
display will briefly indicate Err  
If this occurs, try sending the data again. If the problem persists, it may indicate a bad  
MIDI cable connection or a problem with the data itself.  
Realtime Modulation Functions  
You can use MIDI controller messages to simultaneously control up to two  
parameters in the MicroVerb 4, such as delay time, room decay, etc. Modulation  
functions are “hard-wired” in each Program, and therefore cannot be changed. MIDI  
Controllers 1 (Modulation) and 11 (Foot Controller) are always active on the  
MicroVerb 4, and will typically modulate the Edit A and Edit B parameter values.  
The parameters in each Program which can be modulated via MIDI have been  
chosen very carefully to provide the most-desired modulation combinations. For  
example, on a Multieffect with Chorus and Reverb, Controller 1 controls Reverb  
Decay and Controller 11 controls Chorus Rate. These modulators add positive  
modulation to the saved program value. The minimum Modulation amount will give  
you the saved value, while the maximum Modulation value will increase that  
parameter to its maximum possible setting. On a few programs, only one parameter  
is available for modulation.  
Remember that Modulation is always positive when setting up your programs. For  
example, if you wish to modulate Lezlie speed during a performance, make sure you  
choose a Program with the “Slow” speed saved into memory. This way, when the  
modulation is increased, the motor will speed up. If the Lezlie Program has a “Fast”  
speed saved, increasing the modulation amount will have no effect since that  
parameter is already at its maximum value.  
* Note: If audio is going through a chorus effect and the depth parameter is changed,  
you will notice audible “clicks”. This is due to the fact that the processor is making  
significant changes in the effect’s algorithm. We recommend that you change the  
setting of this parameter only while no audio is running through the effect.
