Knob 2: Depth Controls the amount of pitch shifting for each voice. Lower settings provide subtle thickening
and warmth to a track, while higher settings give a more pronounced, multi-voice effect.
Knob 3: Voices Controls the number of additional Chorus voices. Up to 8 voices can be added, continuously
variable in 100 individual steps.
Flanger
This effect was originally created by simultaneously recording and playing back two identical programs on
two tape recorders, then using hand pressure against the ange of the tape reels to slow down rst one
machine, then the other. The result was a series of changing phase cancellations and reinforcements, with
characteristic swishing, tunneling, and fading sounds.
Knob 1: Speed Controls the modulation rate of the Flanger effect.
Knob 2: Depth Controls the intensity of the Flanger effect. Lower settings provide a slight “whooshing” sound
while higher settings provide a much more dramatic “jet airplane” sound.
Knob 3: Regeneration This knob controls the amount of modulated signal being fed back into the input,
creating feedback. Higher amounts add a metallic resonance to the signal.
Phaser
The Phaser automatically moves frequency notches up and down the spectrum of the signal by means of a
low frequency oscillator (LFO), creating an oscillating “comb-lter” type effect. This effect is very userful on
keyboards (especially pad presets) and guitars.
Knob 1: Speed Controls the modulation rate of the Phaser effect.
Knob 2: Depth Controls the intensity of the Phaser effect.
Knob 3: Regeneration This knob controls the amount of modulated signal being fed back into the input,
creating feedback. Higher amounts add more resonance to the effect signal.
Tremelo/Pan
Tremolo and Panner create rhythmic changes in signal amplitude. Tremolo affects both channel’s amplitude
simultaneously, while the Panner affects the amplitude of each channel in an alternating manner.
Knob 1: Speed Controls the modulation rate of the Tremolo/Panner.
Knob 2: Depth Controls the intensity of the volume amplitude change.
Knob 3: Phase Controls whether the amplitude change occurs in both channels simultaneously (Tremolo)
or alternates between channels (Panner).
Vibrato
Vibrato is obtained by smoothly varying the pitch of the signal just sharp and at of the original at a deter-
mined rate. Vibrato Stereo (Wet only) Rotary Mono (Wet only) Tremolo/Pan Stereo (Wet only)
Knob 1: Speed Controls the modulation rate of Vibrato.
Knob 2: Depth Controls the maximum amount of pitch shift. Lower settings result in a mere “warble,” while
higher settings produce a more exaggerated “wow” sound.
Knob 3: Phase This control sets left and right channel waveforms out of phase, resulting in a left-to-right
panning motion. This effect shifts the frequency spectrum of the input signal. Altering the pitch of a sound
produces a wide range effects - from subtle detunes to full interval shifts up or down a two octave range.
FACTORY RESET
Use this function if you want to erase all program data and restore the effects processor to its factory state. To
perform a Factory Reset press and hold the STORE button while powering up the console. Once the effects
processor has initialized (after three seconds), then release the STORE button and the effects processor will
be restored to its factory state.
