Alesis QUADRAVERB Plus USERS MANUAL ADDENDUM.
2 2 INTRODUCTION The QuadraVerb Plus is an upgraded version of the original QuadraVerb . The many new features that are now available are made possible by a simple software update, which requires only the replacement of its EPROM ( E rasable P rogrammable R ead O nly M emory).
3 3 • AUTO PANNING - Auto Panning allows a signal to automatically pan from side to side (when the outputs are connected in stereo) at a selected rate and depth.

7 7 6) Pressing the "Up" PAGE button again will select the individual Tap output volume to be edited, which will read: TAP 1 VOLUME: 50 Pressing the VALUE buttons will select the desired Output Volume.
8 8 PLEASE NOTE: As a short cut, while page four through eight are active, the Tap Number under edition can be incremented by pushing the DELAY switch.

10 10 AUDIO TRIGGER SAMPLING: O N 4) Now press the BYPASS button. The display will read: WAITING FOR AUDIO THRESHOLD 5) Send a signal to the QuadraVerb Plus . When the first LED (-18dB) lights, the input signal has passed the audio threshold and recording has begun.
11 11 PLAYING BACK A SAMPLE There are three ways to play back a recorded sample: from the front panel, from an audio trigger, or through MIDI. Playback from the front panel (manual playback) would normally be used when you want to manually trigger a recorded sample.
12 12 To play again, repeat steps 2A and 3A. PLAYBACK FROM AN AUDIO TRIGGER 1) Press the DELAY button. The display will read: SAMPLE PLAYBACK: O NE SHOT 2) Press the "Up" VALUE button until .
13 13 MIDI TRIGGER: G ATED In the MIDI Gated mode, the sample will stop playing as soon as the key is released. 3) Pressing the VALUE "Down" button once will select the next display, which w.
14 14 MIDI TRIGGER BASE: 060 The Base value is the note where the sample will play back with no pitch change. 4) Press the VALUE buttons to select the desired note.
15 15 This page will determine at what point in the sample that playback will start. 3) Press the VALUE button to select the desired Start time. The start can be anywhere in the sample in 10 millisecond steps. When the start of the sample is moved, the length of a loop is maintained unless the end of the sample is reached before the loop duration.
16 16 4) Press the VALUE buttons to select the desired recorded Sample signal level. The range is 0 to 99 with 0 being off. PANNING AND TREMOLO MODULATION Auto Panning and Tremolo modulation of the EQ output has been added to the EQ->PITCH->DELAY->REVERB and 5 BAND EQ->PITCH->DELAY configurations.

23 23 SELECTING THE RESONATOR CONFIGURATION The Resonators are accessed through new Configuration 7, which is RESONATOR->DELAY->REVERB. The block diagram of this configuration is as follows: FIG.
24 24 RESONATOR GATE MODE: M IDI GATED PLEASE NOTE: When playing the resonators from MIDI, the five pitches are determined by up to five notes played on the MIDI keyboard. When used this way, the resonator's tunings should be set to zero for proper keyboard tuning.
25 25 EDITING THE DELAY AND REVERB PARAMETERS The parameters and mode of adjustment of the Delay and Reverb sections are identical to the original LEZLIE-> DELAY->REVERB configuration as found on page 69 of the QuadraVerb Users Manual.
