54: Organ Vib/Chorus
(Organ Vibrato/Chorus)
This effect simulates the chorus and vibrato circuitry of a vintage
organ. The modulation speed and depth can be customized.

55: Rotary Speaker
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.

a: Mode
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.
