Modulation and Pitch Shift (Mod./P.Shift)

This effect simulates the chorus and vibrato circuitry of a vintage
organ. The modulation speed and depth can be customized.

If Control Mode=Preset, you can use c: Preset Type to select the
effect. In this case, the Custom Mix/Depth/Speed settings are
ignored. If Control Mode=Custom, the Custom Mix/Depth/
Speed settings are valid, and the c: Preset Type setting is ignored.

If Preset Type=V1 and Src=JS+Y, you can set this to +5 and
move  JS  +Y  to  control  the  effect  in  the  order  of
V1

 C1 V2 C2 V3 C3.

This effect simulates a rotary speaker, and obtains a more realis-
tic sound by simulating the rotor in the low range and the horn
in the high range separately. The effect also simulates the stereo
microphone settings.

This parameter sets how the modulation source switches
between rotation and stop.

When  Mode = Toggle, the speaker rotates or stops alternately
each time you press the pedal or move the joystick. Via MIDI,
rotation will switch between start and stop each time the modu-
lation amount exceeds 64.

When  Mode  =  Moment, the speaker rotates by default, and
stops only when you press the pedal or move the joystick. Via
MIDI, modulation values above 64 make the speaker rotate, and
values below 64 make it stop.
