User manual ALESIS QUADRAVERB USER PROGRAMS

[. . . ] All patches originally written for the QuadraVerb will sound the same on the QuadraVerb Plus. This addendum only describes the new features. Full instructions on the operation of your unit can be found in your User's Guide. NEW FEATURES New features available on the QuadraVerb Plus include Sampling, Ring Modulator, and Resonator configurations, plus the addition of Multi Tap Delay, Auto Panning, and Tremolo Modulation on original configurations where these features are applicable. In addition, the Quadraverb's extensive MIDI implementation has been greatly enhanced to include real-time parameter control of parameters such as the Delay, Volume, and Feedback for each of the 8 individual taps in the Multi Tap Delay configuration, as well as the Auto Panning and Tremolo's Modulation Speed and Depth. [. . . ] The display will read: 9 9 AUDIO TRIGGER SAMPLING: ON 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. For the best recorded signal, raise the input level control so that the -6dB LED lights. The signal will be distorted if the red "Clip" LED lights. RECORDING FROM THE FRONT PANEL 1) Press the DELAY button. The display will read: SAMPLE PLAYBACK: ONE SHOT This page is primarily for playback and can be bypassed for now. 2) Press the PAGE up button three times. The display will then read: AUDIO TRIGGER SAMPLING: ON 3) Press the VALUE button to select the Audio Trigger Off mode. The display will read: AUDIO TRIGGER SAMPLING: OFF 4) Now, when ready to sample, press the BYPASS button. The display will read: SAMPLING. . . . . . . . . . . . . . . . . . . For the best recorded signal, raise the input level control so that the -6dB LED lights. 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. In this case, the loop duration will be from the start to the actual end of the sample regardless of the loop duration. However, the duration value will remain intact and in effect as soon as the user adjustment of the loop start will permit the proper length. The range is from 0 through 1. 5 seconds in 10 millisecond increments. 4) Press the PAGE "Up" button. The display will read: SAMPLE LENGTH: 1. 55 SECONDS This page will determine the length of the sample playback. 5) Press the VALUE button to select the desired Sample length time. ADJUSTING THE SAMPLE MIX PARAMETERS The MIX section allow for adjusting the relative balance between the direct signal, and the recorded sample playback signal. The display will read: DIRECT SIGNAL LEVEL: + 50 This page controls the level of the direct signal. 2) Press the VALUE buttons to select the desired direct signal level. 3) Press the "Up" PAGE button to select the next page. The display will read: SAMPLE PLAYBACK SIGNAL LEVEL: + 50 This page controls the output level of the recorded sample. 15 15 4) Press the VALUE buttons to select the desired recorded Sample signal level. [. . . ] This means that the fundamental has been shifted to 300Hz, the 2nd harmonic is now at 800Hz (normally it should be 2 times the fundamental, or 600Hz), and the 4th harmonic is 1. 8KHz (normally it should be 1. 2KHz). Since the ratio between the input signal's harmonics is not preserved, the resulting sound is drastically different from the original. While usual ring modulators only provide a fixed mix of the Up and Down spectrums, the 20 20 100Hz 500Hz 1KHz Freq. algorithm implemented in the QuadraVerb Plus gives independent access to the Up and Down version of the original spectrum. The ring modulator treatment will be most valuable for special effect on voices or sound effects. SELECTING THE RING MODULATOR The Ring Modulator is accessed through new Configuration 6, which is RING MODULATOR->DELAY->REVERB. [. . . ]
