INTRODUCTION

Alesis

16 BIT MULTI-EFFECTS PROCESSOR WITH REAL-TIME MIDI PARAMETER CONTROL

MIDIVERB III

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

• Up to 4 simultaneous effects - Delay, Reverb, Chorus, EQ

• Simplified user interface for faster set-up

• Clip and Signal Present LEDs

• Inputs and outputs via 1/4" phone jacks

• +4dBV capable for use in the studio or on stage

• MIDI program MAPPING for programmable program selection

• Programmable levels for Delay and Reverb

INTRODUCTION

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:

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.

This section gives a brief explanation of all front panel and rear panel controls and
indicators.

Section 3 deals with the interfacing of MIDIVERB III to another MIDI device or into a
MIDI system.

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.

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.

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

A. MONO IN - STEREO OUT

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

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

SECTION 4

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:

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
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).

If we desire to select program 023, for example, we could simply press
and hold the "up"
point, the MIDIVERB III's front panel would look like this:

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 (

SECTION 4

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:

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

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.

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.

REVERB DECAY

DELAY

The programmable parameters are:

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.

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

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.

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.

CHORUS SPEED

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.

The Chorus level is always the same and is either On or Off depending
upon the Configuration selected.

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.

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.

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

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.

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

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
