20: St.Flanger

(Stereo Flanger)

This effect gives a significant swell and movement of pitch to the sound. It is more effective when applied to a sound with a lot of harmonics. This is a stereo flanger. You can add spread to the sound by offsetting the phase of the left and right LFOs from each other.

a: 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, i: W/D

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 “W/D”, and if you set a negative value for both “Feedback” and “W/D”.

h: High Damp

This parameter sets the amount of damping of the feedback in the high range. Increasing the value will cut high-range harmonics.

21: St.Rndm Flang

(Stereo Random Flanger)

The stereo effect uses a step-shape waveform and random LFO for modulation, creating a unique flanging effect.
