The QuadraVerb GT can insert between your guitar and subsequent effects units or amplification systems. This lets you use the amp's overdrive options to further color the QuadraVerb GT's sound. [. . . ] This sets the time between successive delay signals, and is variable in 1 ms increments from 1 millisecond to the maximum delay available in the configuration. As mentioned under Delay Type, the maximum delay depends on the selected reverb type and the configuration. 45 Delay Feedback (configs 1, 2, 3, 4, 6, 7) With Mono or Ping Pong selected for delay type, the display shows: DELAY FEEDBACK: 33% With Stereo selected, this will say DELAY FEEDBACK LEFT. Increasing the feedback increases the number of successive echoes; each echo will be softer than its predecessor. Right Delay Time (configs 1, 2, 3, 4, 6, 7) This page appears only if Stereo is selected as the delay type, and says: RIGHT DELAY TIME: 400 milliseconds This sets the time between successive delay signals, and is variable in 1 ms increments from 1 millisecond to the maximum delay available in the configuration. As mentioned under Delay Type, the maximum delay depends on the selected delay type and the configuration. Delay Feedback Right (configs 1, 2, 3, 4, 6, 7) This page appears only if Stereo is selected as the delay type, and says: DELAY FEEDBACK RIGHT: 33% Increasing the feedback increases the number of successive echoes; each echo will be softer than its predecessor. 46 Multi Tap Number (config 4 only) The display says: TAP NUMBER: 8 This parameter selects the tap to be edited on subsequent pages. IMPORTANT: When the Delay Time, Volume, Panning, or Feedback pages are selected, you can select the next higher-numbered tap by pressing the DELAY button. Going past 8 returns you to 1. Multi Tap Delay Time (config 4 only) The display says: TAP X DELAY TIME 0125 millisecs X is the number of the tap selected for editing. Note that each taps delay is cumulative. Example: If tap 1 is 150 ms and you want tap 2 to be 300 ms and tap 3 to be 400 ms, set tap 2s delay time to 150 ms (150+150=300) and tap 3s delay time to 100 (150+150+100=400). If you change a taps delay time, all higher numbered taps will be offset by the same amount that you changed the taps delay time. Multi Tap Volume (config 4 only) The display says: TAP X VOLUME: 50 X is the number of the tap selected for editing. This sets the volume of the selected tap. 47 Multi Tap Panning (config 4 only) The display says: TAP X PANNING: LEFT 00 RIGHT X is the number of the tap selected for editing. This pans the tap output anywhere in the stereo field between full left (99) and full right (99). High LFO depth settings may make a signal seem out of tune unless you slow down the LFO speed. 50 Pitch Feedback (Chorus and Flange only) The display says: PITCH FEEDBACK: 00% Pitch feedback sends some of the output signal back to the input, from 00% to 99%. Higher numbers give a sharper, more resonant sound. Trigger Flange (Flange only) The display says: TRIGGER FLANGE: OFF When on, a silence between incoming notes resets the flanger to its highest point, and as soon as a new note appears, the flanger sweeps downward. If you continue to holding a sustaining note, the flanger will sweep according to the LFO parameters. Trigger flange works best with notes having a percussive attack. Pitch Detune (Detune only) The display says: DETUNE AMOUNT: -15 This sets the amount of detuning in cents from -99 to +99 (+ is sharp, - is flat). 51 Phaser Speed (Phaser only) The display says: PHASER SPEED: 04 This parameter alters the rate of phaser modulation, from 01 (slow) to (fast) 99. Phaser Depth (Phaser only) The display says: PHASER DEPTH: 95 This parameter determines the degree to which the modulation affects the phaser effect. Higher numbers increase the phaser sweep. Lezlie Stereo Separation (config 2 only) The display says: LEZLIE STEREO SEPARATION: 80 This parameter determines the extent to which bass and treble will be spread across the stereo image. Higher numbers increase the degree of separation. Lezlie Motor Control (config 2 only) The display says: LEZLIE MOTOR CONTROL: ON 52 Because the speakers in a mechanical rotating speaker system weigh a lot, they take a while to get up to speed from a dead stop, and take a while to slow down when turned off. Turn this parameter off to slow the speakers down to a stop, or on to speed them up to the speed set on the next page; its a natural for MIDI control (sections 6. 1-6. 2). Lezlie Speed (config 2 only) The display says: LEZLIE SPEED: FAST Mechanical rotating speaker systems generally offer two speeds, slow and fast. The QuadraVerbs simulated rotating speaker gives you two speeds also. Ring Modulator Spectrum Shift (config 6 only) The display says: SPECTRUM SHIFT: 100Hz This determines how much the up and down harmonic signals will be shifted with respect to the original input signal. Ring Modulator Output Mix (config 6 only) The display says: RING MOD. OUTPUT MIX: DOWN 00UP This varies the balance between the up and down signals. At 00, there is an equal blend of both signals. At 99, the output consists entirely of the 53 upshifted signal. [. . . ] The "omni" message determines how many channels will be recognized. Omni On means that data from all channels will be received; Omni Off limits the number 119 of channels, usually to one. The "mono/poly" message deals with voice assignment within the synthesizer. In Mono mode, only one note at a time plays in response to voice messages; in Poly mode, as many voices can play notes as are available to play notes. [. . . ]
