Alesis MIXING CONSOLES - Manual

INTRODUCTION 2 Alesis MIDIVERB III 16 BIT MULTI-EFFECTS PROCESSOR WITH REAL-TIME MIDI PARAMETER CONTROL INTRODUCTION The Alesis MIDIVERB III is a high quality multi-effects unit whichfeatures up to 4 simultaneous effects (Delay, Reverb, Chorus, EQ) at afull 15KHz bandwidth and with 16 bit resolution...

INTRODUCTION 4 HOW TO USE THIS MANUAL Since a musician's time is better spent making music than reading manuals, we'vetried to make this manual not only easy to use, but also fast and easy to find thingswhen you need to. Therefore, the manual is broken down to 6 major sections, ofwhich Section 4 wil...

QUICK START 5 SECTION 1 MIDIVERB III QUICK START FACTORY PROGRAMS The MIDIVERB III contains 200 factory supplied programs, 100 of whichare stored in memory locations 000 to 099 and repeated again inlocations 100 to 199.Only the programs in locations 100 to 199 can be permanently alteredand stored as...

SECTION 1 6 2) Pressing the EDIT button again will select the upper LED which indicates that the top row of edit functions on the top row ofbuttons can be accessed. 3) Select the desired function to be edited. The stored value of the parameter will appear in the numeric display and thebutton will li...

DESCRIPTION OF CONTROLS 9 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 counterc...

DESCRIPTION OF CONTROLS 13 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 through16. Pressing the MIDI button a second time selects if the MIDIVERB III will accept MIDI Program Change commands. Pressing the MIDI but...

SECTION 2 14 The other half of the MIDI program MAPPING section when in the EDITmode, the INT. PROG (Internal Program) button selects the internal MIDIVERB III program (from 000 to 199) that will be chosen by theexternal MIDI program number that is selected by the MIDI PROG button. When in the PROGR...

DESCRIPTION OF CONTROLS 15 Retransmits MIDI information received by MIDIVERB III to other MIDIunits if the MIDI ECHO function is enabled. Also used as a MIDI OUT jack for MIDI system exclusive data dumps. BYPASS JACK The BYPASS jack bypasses the effects of the MIDIVERB III and supplies only Direct S...

INTERFACING MIDIVERB III 17 SECTION 3 INTERFACING MIDIVERB III INSTRUMENTS MICROPHONES The Alesis MIDIVERB III has high impedance inputs that are ideallysuited for use either with instruments or line level signals. Althoughmicrophones can be connected directly into the MIDIVERB III, it isrecommended...

SECTION 3 18 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 interfacewith the extremely low signal levels of...

SECTION 3 20 CONNECTION TO THE MAIN OUTPUTS Still another way of interfacing the MIDIVERB III to a mixer or recordingconsole would be in-line across the output of your mixing console (SeeFigure 4).This setup would be used only if you needed to effect the entire mix. FIGURE 4 STEREO CONNECTION TO THE...

SECTION 4 22 SECTION 4 USING MIDIVERB III PROGRAM MODE When power is first turned on, the MIDIVERB III automatically resets tothe Program mode and the last program selected before the power wasturned off will be currently selected. For the purpose of illustration, let's assume that you are turning y...

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 ...

SECTION 4 26 REVERB Reverb can be thought of as a great number of distinct echos, calledreflections, that occur so fast that our ear hears them blurred together asone. In nature, different size spaces give distinctly different soundingreverbs, depending upon the size and shape of the space (called R...

USING MIDIVERB III 27 REVERB DECAY The Reverb Decay determines the length of time that the Reverb willsound before it finally fades away. It is not used in the Reverse 1 and 2Algorithms. It is functional in all others. DELAY The Delay section of the MIDIVERB III can be used in two modes,depending up...

SECTION 4 28 There are 24 different Chorus Algorithms (Chorus versions), in theMIDIVERB III. Each algorithm has a different sound and simulates adifferent pitch based effect.There are two major types of algorithms: Chorus and Flanging (seeexplanation below). Both Chorus and Flanging have 6 algorithm...

USING MIDIVERB III 29 variables are available, from varying the Speed and Depth of the LFO tofeeding 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 adry signal and a separate Delay section for both left and right channel...

SECTION 4 30 INPUT EQ The INPUT EQ is a high-cut filter that rolls off the high frequencyresponse 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 ...

USING MIDIVERB III 31 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, keyboardaftertouch, keyboard note number, keyboard velocity, sustain pedal, orbreath controller.
