User manual ALESIS QUADRAVERB PLUS

[. . . ] Alesis QUADRAVERB Plus USERS MANUAL ADDENDUM 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 (Erasable Programmable Read Only Memory). The hardware of the QuadraVerb remains unchanged. The operation of the QuadraVerb Plus is identical to the original QuadraVerb and all original features of the QuadraVerb are retained in the QuadraVerb Plus . [. . . ] Playback from an audio trigger is normally used when replacing one audio source with a recorded sample, as in the case of replacing a snare drum on a tape track with a better recorded sample. Playback through MIDI enables a recorded sample to be played from a MIDI keyboard. PLAYBACK FROM THE FRONT PANEL 1) Press the DELAY button. The display will read: SAMPLE PLAYBACK: ONE SHOT One Shot means that once a sample is initiated, it will play until the end of the sample and then stop. 2) To begin playback, press the EQ button. The sample will play to the end and then automatically stop. To playback again, press the EQ button again. 3) The volume of the sample can be increased or decreased by the OUTPUT control of the QuadraVerb Plus. 1A) If you wish to have the sample play back continuously until told to stop, press the "Down" VALUE button. The display will read: SAMPLE PLAYBACK: LOOPING 2A) To begin playback, press the EQ button. The display will then read: PUSH EQ TO STOP SAMPLE PLAYBACK 3A) To stop playback, press the EQ button again. The display will then read: PUSH EQ TO TRIG. The next display will read: MIDI TRIGGER LOW LIMIT: 000 2) Press the VALUE "Up" button to select the lowest desired note to trigger the recorded sample. 3) Press the PAGE "Up" button. The next display will read: 13 13 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. 5) Press the PAGE "Up" button. The next display will read: MIDI TRIGGER HIGH LIMIT: 127 6) Press the VALUE "Down" button to select the highest desired note to trigger the recorded sample. Note number 60 = Middle C. PLEASE NOTE: · Because of the nature of sampling, the timing of the sample as well as the pitch will change substantially the farther away from the base note that it's triggered, with the higher notes sounding like "munchkins" and the lower notes like "giants". This is a normal phenomena that occurs during sample playback. The pitch of the sample will follow within a 2 octave range and will loop back into the range if any note information falls outside of the 2 octave range. For instance, if the base note has been selected to note number 60 (Middle C or C3) and note number 84 (C5) is played, the sample pitch will be triggered 1 octave higher than the bass (C4). · ADJUSTING THE SAMPLE PLAYBACK LENGTH In any playback mode it is possible to adjust the sample playback length in order to either ignore unwanted sampled material or "dead air", or in order to make a loop more musical. This is accomplished in the following manner. The display will read: SAMPLE PLAYBACK: ONE SHOT 2) Press the PAGE "Up" button. The display will read: SAMPLE START: 0. 00 SECONDS 14 14 This page will determine at what point in the sample that playback will start.
