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.

move JS +Y to control the effect in the order of

054: Rotary Speaker

This effect simulates a rotary speaker, and obtains a more
realistic 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.

Amt
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 modulation 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.
b: Speed Switch
This parameter controls how the rotation speed (slow and
fast) is switched via the modulation source.
When Mode = Toggle, the speed will switch between slow
and fast each time you press the pedal or move the joystick.
Via MIDI, the speed will switch each time the modulation
amount exceeds 64.
When Mode = Moment, the speed is usually slow. It
becomes fast only when you press the pedal or move the
joystick. Via MIDI, modulation values above 64 set the
speed to Fast, and values below 64 set it to Slow.
Wet / Dry
c: Manual Speed Ctrl
If you wish to control the rotation speed manually, instead
of switching between Slow and Fast, select a modulation
source in the Manual Speed Ctrl parameter. If you don't
want to use manual control, set this to Off.
Wet / Dry
d: Horn Acceleration
e: Rotor Acceleration
On a real rotary speaker, the rotation speed accelerates or
decelerates gradually after you switch the speed. The Horn
and Rotor Acceleration parameters set the transition times
between fast and slow speeds.

This is a simulation of stereo microphone settings.
