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.

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 .

DESCRIPTION OF CONTROLS
SECTION 2
DESCRIPTION OF CONTROLS
FRONT PANEL
INPUT
The INPUT control is a stereo control that determines the master volume
level of the signal being fed into both inputs of the MIDIVERB III.
MIX
The MIX control determines the ratio of direct to effect signal. Full
counterclockwise (to the left) applies only direct signal to the outputs of
MIDIVERB III. Full clockwise (to the right) applies only effect signal to
the outputs.
OUTPUT
The OUTPUT control determines the output level of the MIDIVERB III's
stereo output jacks. Although this control is not programmable, it is
possible to program some of the output levels internally via software
(See Editing the Mix Levels).
CLIP INDICATOR
The red CLIP INDICATOR LED indicates the onset of distortion. This LED
should only light occasionally during normal use.
SIGNAL PRESENT LED
The green SIGNAL PRESENT LED indicates that a signal is currently being
fed into the MIDIVERB III. This LED should be frequently lit during
normal use.
LED DISPLAY
The MIDIVERB III contains an LED display which indicates the current
program number or parameter value.
9
SECTION 2
VALUE
The VALUE buttons can be used to select the desired number or, once a
desired parameter has been selected, edit the parameters value.
PROGRAM
The PROGRAM button will display the number of the current program.
A period appearing behind the program number indicates that a
parameter or function has been edited and is different from its stored
value.
STORE
The STORE button allows you to store an edited program into any
available program location. By pressing the STORE button once, the de-
sired location to be stored to can be accessed by pressing and holding
one of the VALUE buttons. Pressing the STORE button a second time will
save the program.
EDIT
Pressing the EDIT button will allow access to various parameters for
editing. When the EDIT button is selected, the lower of the two LEDs
adjacent to the button will light, and indicates that the lower row of
parameters of the top row of buttons can be accessed for editing.
Pressing the EDIT button a second time will select the upper row of
parameters of the top row of buttons.
REVERB/1
When in the EDIT mode, pressing the REVERB button will access either
the REVERB ALGORITHM or REVERB DECAY time for editing,
depending which EDIT LED is lit.
The ALGORITHM parameter offers
selection of any of 20 Reverb Algorithms, each with different reverb
characteristics such as frequency response, diffusion, density, etc.(see
programming chart). The REVERB DECAY parameter allows the user to
adjust the decay of the reverb from very short to very long as required.
After pressing the REVERB button, pressing the VALUE buttons will select
the desired ALGORITHM choices or DECAY levels.
When in the PROGRAM mode, this is button 1 of the keypad for
selecting a program by directly entering the desired program number.
10
DESCRIPTION OF CONTROLS
DELAY/2
When in the EDIT mode, pressing the DELAY button will access either the
DELAY TIME or DELAY REGENERATION amount for editing, depending
which EDIT LED is lit. The DELAY TIME parameter allows the user to
adjust the time between repeats as required.
The DELAY
REGENERATION parameter adjusts the number of repeats.
After pressing the DELAY button, pressing the VALUE buttons will select
the desired DELAY TIME or REGENERATION levels.
When in the PROGRAM mode, this is button 2 of the keypad for
selecting a program by directly entering the desired program number.
CHORUS/3
When in the EDIT mode, pressing the CHORUS button will access either
the CHORUS ALGORITHM or CHORUS SPEED for editing, depending
which EDIT LED is lit. The ALGORITHM parameter offers selection of a
wide variety of chorused effects such as mono and stereo chorus, mono
and stereo flanging, variations of these with different depths and
feedback, etc.(see programming chart). The SPEED parameter affects
the sweep speed of the selected effect as required.
After pressing the CHORUS button, pressing the VALUE buttons will select
the desired ALGORITHM choices or SPEED levels.
When in the PROGRAM mode, this is button 3 of the keypad for
selecting a program by directly entering the desired program number.
EQ/4
When in the EDIT mode, pressing the EQ button will access either the
INPUT EQ or EFFECT EQ, depending which EDIT LED is lit. The INPUT
EQ is a high-cut filter that determines the frequency response of the
incoming signal. The EFFECT EQ is a high-cut filter that is part of the
currently selected effect. For example, with effects that have reverb, the
EFFECT EQ determines the high frequency decay of the reverb. When
used with the Delay, the EFFECT EQ determines the high frequency
response of the regeneration (number of repeats).
After pressing the EQ button, pressing the VALUE buttons will select the
desired EQ rolloff frequency point.
When in the PROGRAM mode, this is button 4 of the keypad for
selecting a program by directly entering the desired program number.
11
SECTION 2
MIX/5
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 Chorus level is always the same and is either On or Off
depending upon the Configuration selected.
After pressing the MIX button, pressing the VALUE buttons will select the
desired levels.
When in the PROGRAM mode, this is button 5 of the keypad for
selecting a program by directly entering the desired program number.

MIDIVERB III parameters isuch as Reverb Decay Time or Reverb Level
in real time from a MIDI controller like the pitchwheel, mod wheel,
keyboard aftertouch, keyboard note value, keyboard velocity, sustain
pedal, breath controller, or volume control on a synthesizer or other MIDI
device. After pressing the MOD button, pressing the VALUE buttons
selects the available choices.
When in the PROGRAM mode, this is button 7 of the keypad for
selecting a program by directly entering the desired program number.
MIDI/8
12
DESCRIPTION OF CONTROLS
When in the EDIT mode, the MIDI button is used to select the send and
receive channel for the MIDIVERB III. The range is channel 01 through
16.
Pressing the MIDI button a second time selects if the MIDIVERB III will
accept MIDI Program Change commands.
Pressing the MIDI button a third time selects the ECHO On or Off
function. This will echo any MIDI information that the MIDIVERB III
receives at its MIDI input (except for system exclusive messages that are
specifically for the MIDIVERB III) back out its MIDI output.
The MIDI button can also be used to transmit MIDIVERB III programs 100
through 199 via MIDI system exclusive. Simply hold the MIDI button and
press STORE.
The MIDI functions are global functions and are not stored with an
individual program.
When in the PROGRAM mode, this is button 8 of the keypad for
selecting a program by directly entering the desired program number.
MIDI MAPPING
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.
When in the PROGRAM mode, this is button 9 of the keypad for
selecting a program by directly entering the desired program number.
13
SECTION 2
The other half of the MIDI program MAPPING section when in the EDIT
mode, 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 that is selected by the MIDI PROG button.
When in the PROGRAM mode, this is button 0 of the keypad for
selecting a program by directly entering the desired program number.
BYPASS
The BYPASS button bypasses the effects of the MIDIVERB III and
supplies only Direct Signal Level to the stereo outputs. When the signal
is bypassed, the BYPASS LED will light.
BYPASS is also connected to the Bypass Jack on the rear panel and can
be activated by a momentary footswitch.

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

SECTION 3
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).
20
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.
21
SECTION 4
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
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.
1) Select the EDIT button. The lower of the the two LEDs
adjacent to the EDIT button will light, the PROGRAM LED will
turn off, and the LED for the function or parameter last
selected will light.
This indicates that the bottom row of functions of the top row of
buttons can be accessed, so now the REVERB, DELAY,
CHORUS, EQ, and MIX buttons will control REVERB DECAY,
DELAY REGENERATION, CHORUS SPEED, EFFECT EQ,
and DELAY MIX. (The illustration indicates a Reverb Decay
time of 50).
50
2) Pressing the EDIT button again will select the upper LED which
indicates that the top row of edit functions on the top row of
buttons can be accessed.
Now the REVERB, DELAY, CHORUS, EQ, and MIX buttons control
REVERB
ALGORITHM,
DELAY
TIME,
CHORUS
ALGORITHM, INPUT EQ, and REVERB MIX. (The illustration
indicates that a Reverb Algorithm of "ro1" or Room 1 has been
chosen).
24
USING MIDIVERB III
ro1
3) Select the desired function to be edited. The stored value of
the parameter will appear in the numeric display and the
button will light up.
In this case we will edit the DELAY TIME. When we select the
DELAY button, the display will read:
080
4) Press either VALUE button to adjust the desired parameter.
5) Select another function to be edited, if desired.
PLEASE NOTE:
—Once a parameter has been edited, the dot to the right of the right-
most numeric digit will light when in PROGRAM mode (program
number displayed and PROGRAM LED lit).
—At this point, selecting a new program either by the VALUE buttons or
the keypad will cause the edited program to be lost. Be sure to save
your program first!
(See next section)
—The parameters on the bottom row of buttons can be selected when
either Edit LED is on.
—At any time you can return to the default selection or value by
pressing both VALUE buttons at the same time.
MIDIVERB III PROGRAMMABLE
FUNCTIONS
25
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:

ALGORITHM
27
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.

The programmable parameters are:
29
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.
34
USING MIDIVERB III
PLEASE NOTE: In all Configurations except #14 and 15, the maximum delay is 100
milliseconds. In Configurations #14 and 15, the maximum delay time is 490
milliseconds.

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.

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
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.

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!!
