188 Effects
Pitch/Phase Mod.
b: LFO Shape
Changing the LFO waveform shape controls the peak
sweep of flanging effects.
g: Feedback, h: Wet/Dry
The peak shape of the positive and negative “Feedback”
value is different. The harmonics will be emphasized
when the effect sound is mixed with the dry sound if you
set a positive value for both “Feedback” and “Wet/Dry”,
and if you set a negative value for both “Feedback” and
“Wet/Dry”.
g: High Damp [%]
This parameter sets the amount of damping of the feed-
back in the high range. Increasing the value will cut high-
range harmonics.
021: RandomFlang
(Stereo Random Flanger)
The stereo effect uses a step-shape waveform and random
LFO for modulation, creating a unique flanging effect.
022: Envel.Flang
(Stereo Envelope Flanger)
This Flanger uses an envelope generator for modulation. You
will obtain the same pattern of flanging each time you play.
You can also control the Flanger directly using the modula-
tion source.
c: Sweep Mode, c: Src
This parameter switches the flanger control mode. With
“Sweep Mode” = EG, the flanger will sweep using the
envelope generator. This envelope generator is included
in the envelope flanger, and not related to the Pitch EG,
Filter EG, or Amp EG.
