026: BiphaseMod.

(Stereo Biphase Modulation)

This stereo chorus effect adds two different LFOs together. You can set the Frequency and Depth parameters for each LFO individually. Depending on the setting of these LFOs, very complex waveforms will create an analog-type, unstable modulated sound.

027: Vibrato

(Stereo Vibrato)

This effect causes the pitch of the input signal to shimmer. Using the AutoFade allows you to increase or decrease the shimmering speed.

d:LFO Frequency Mod, a: AUTOFADE Src, a: Fade-In Rate

b:Fade-In Delay [msec]

When “LFO Frequency Mod” is set to AUTOFADE, you can use the modulation source selected in “AUTO FADE Src” as a trigger to automatically fade in the modulation amount. When “BPM/MIDI Sync” is set to On, you cannot use this.

The “Fade-in Rate” parameter specifies the rate of fade- in. The “Fade-in Delay” parameter determines the time from AutoFade modulation source ON until the fade-in starts.
