User manual ALESIS QUADRAVERB USER PROGRAMS

[. . . ] 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. Also, the Quadraverb Plus lets the user adjust parameters such as the Ring Modulator's Spectrum Shift, Output Up/Down Mix, and Delay/Reverb Up/Down Mix as well as the Pitch and Decay of the Resonator. This allows the user to achieve a greater level of creative control than ever before. [. . . ] In Figure 7B, an additional 250ms is added to Tap #2 which means that it now occurs at 750ms (instead of 500ms as in 7A), and Tap #3 now occurs at 1250ms (instead of 1 second in Figure 7A). SELECTING THE MULTI TAP DELAY CONFIGURATION Multi Tap Delay is accessed through the 5 BAND EQ->PITCH->DELAY configuration. The display will read: SAMPLE PLAYBACK: ONE SHOT This page is primarily for playback and can be bypassed for now. The display will then read: AUDIO TRIGGER SAMPLING: OFF 3) Press the VALUE button to select the Audio Trigger On mode. 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. 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: DIRECT SIGNAL LEVEL: + 50 This page controls the level of the direct signal. 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. 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. Auto Panning allows a signal that has first been routed through the EQ section of either of the above configurations to automatically pan from side to side at a selectable rate. Please note that the effect will only be heard when both the left and right outputs of the Quadraverb are in use. Tremolo Modulation means that a signal that has first been routed through the EQ section of either of the above configurations will vary in volume at a selected rate. Both the depth and rate of the Auto Panning and Tremolo Modulation can be varied and/or modulated by any MIDI modulation source. SELECTING THE PANNING OR TREMOLO CONFIGURATION Auto Panning or Tremolo Modulation is accessed through the EQ->PITCH>DELAY->REVERB or 5 BAND EQ->PITCH->DELAY configurations. To select either configuration, first press the CONFIG button, then press the VALUE buttons until the display reads: CONFIGURATION: EQ>PCH>DL>REVERB or CONFIGURATION: 5BAND EQ>PCH>DL The block diagram of this configuration is as follows: FIGURE 5 EQ->PITCH->DELAY->REVERB BLOCK DIAGRAM 16 16 1 2 1 2 EQ PITCH MIX PITCH OUTPUT DELAY MIX DELAY OUTPUT REVERB REVERB OUTPUT EFFECTS OUTPUT EQ OUTPUT PANNING/ TREMOLO L R DIRECT PRE/POST EQ L R DIRECT OUTPUT FIGURE 6 5 BAND EQ->PITCH->DELAY BLOCK DIAGRAM 1 2 5 BAND EQ PITCH MIX PITCH OUTPUT DELAY DELAY OUTPUT EFFECTS OUTPUT EQ OUTPUT PANNING/ TREMOLO L R DIRECT PRE/POST EQ L R DIRECT OUTPUT EDITING THE PANNING OR TREMOLO PARAMETERS 1) To access the Auto Panning parameters, press the MIX button. The display will then read: DIRECT SIGNAL: PRE-EQ 2) Press the "Up" VALUE button until the next page reads: DIRECT SIGNAL: POST-EQ PANNING or DIRECT SIGNAL: POST-EQ TREMOLO 17 17 This page allows the selection of the direct signal going either Pre-EQ, Post-EQ (both with no panning or tremolo), or Post-EQ with Panning or Post-EQ with Tremolo. 3) Pressing the "Up" PAGE button repeatedly will select the Panning Depth or Tremolo Depth page which will read: EQ PANNING DEPTH 99 or EQ TREMOLO DEPTH 99 . . . . . . . . . depending on if Panning or Tremolo was selected above. Pressing the VALUE buttons will select the desired amount of Panning or Tremolo Depth. [. . . ] In Figure 1B, the Pitch Shift amount has been set to 200Hz, which means that the fundamental and all of its related harmonics are shifted up by the same 200Hz amount. This means that the fundamental has been shifted to 700Hz, the 2nd harmonic is now at 1. 2KHz (normally it should be 2 times the fundamental, or 1. 4KHz), and the 4th harmonic is 2. 2KHz (normally it should be 2. 8KHz). In Figure 1C, the Pitch Shift amount is shifted down by 200Hz, which means that the fundamental and all of its related harmonics are shifted down by the same 200Hz amount. 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).
