Pitch/Phase Mod.

b: LFO Shape

Changing the LFO waveform shape controls the peak sweep of flanging effects.

LFO Shape

LFO Shape = 0...+100 LFO Shape = 0...–100

LFO Waveform=Sine

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.
