26: St.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.
27: St.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.
b: LFO Freq Mod, f: AUTOFADE Src, g: Fade Rate, g: Dly
When “LFO Freq 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 Rate” parameter specifies the rate of fade-in. The “Dly”
parameter determines the time from AutoFade modulation source
ON until the fade-in starts.
The following is an example of fade-in where the LFO speed is
increased from “1.0Hz” to “4.0Hz” when a note-on message is
received.
