Multi Effects
FLANGER
This is a stereo flanger. (The LFO has the same phase for left and right.) It produces a metallic resonance
that rises and falls like a jet airplane taking off or landing.
Parameter Value
PreDelay 0.0–100 msec
Rate 0–127
Depth 0–127
Phase
0–180 deg
Feedback -98–+98 %
REVERB
Adds reverberation to the direct sound, simulating an acoustic space.
Parameter Value
ROOM1, ROOM2,
Reverb Type
STAGE1, STAGE2
Reverb Time
0–127
PreDelay 0.0–100 msec
HF Damp 200–8000 Hz, BYPASS
Wet Gain Low -15–+15 dB
Wet Gain High -15–+15 dB
Explanation
Adjusts the delay time from when the direct sound begins until the
flanger sound is heard.
Frequency of modulation
Depth of modulation
Spatial spread of the sound
Adjusts the proportion of the flanger sound that is fed back into the
effect.
Negative (-) settings will invert the phase.
Explanation
Type of reverb
ROOM1: dense reverb with short decay
ROOM2: sparse reverb with short decay
STAGE1: reverb with greater late reverberation
STAGE2: reverb with strong early reflections
Time length of reverberation
Adjusts the delay time from the direct sound until the reverb sound is
heard.
Adjusts the frequency above which the reverberant sound will be cut.
As the frequency is set lower, more of the high frequencies will be cut,
resulting in a softer and more muted reverberance (BYPASS: no cut).
Amount of boost/cut for the effect sound's lower range
Amount of boost/cut for the effect sound's upper range
LONG REVERB
This is a very rich sounding reverb with a choice of Character.
Parameter Value
Character 0–5
Reverb Time 0–127
PreLPF
16–15000 Hz, BYPASS
PreHPF BYPASS, 16–15000 Hz
Pre EQ Freq 200–8000 Hz
Pre EQ Gain -15–+15 dB
Depth 0–127
HF Damp 16–15000 Hz, BYPASS
LF Damp BYPASS, 16–15000 Hz
EQ Lo -15–+15 dB
EQ Hi -15–+15 dB
SATURATOR
A saturator which distorts the sound is connected in parallel with a compressor, producing a rougher
tonal character and boosting the loudness. This also cuts the low-frequency region of the input audio.
Parameter Value
Saturator Gain 0–127
Saturator Drive 0–127
Saturator Level 0–127
Comp Depth 0–127
Comp Level
0–127
EQ Hi Gain -12–+6 dB
