Rotary Speaker (PRESET bank)
This effect simulates a rotary speaker. A rotary speaker physically turns its internal speaker and horn to produce a Doppler
effect, giving a distinctive character to the sound.
Each aspect of the sound is controlled by the following effect parameters.
Rotary speaker simulation: ROTATE, SPEED, SLOW, FAST, DRIVE, ACCEL
Output level: MIX BAL., LOW, HIGH

Parameter name Range Explanation
ROTATE START, STOP
Speaker rotation start/stop control.
SPEED SLOW, FAST
Speaker rotation speed. Select either SLOW or FAST.
SLOW 0.05—10.00 Hz
Speaker rotation speed when SPEED is set to SLOW.
FAST 0.05—10.00 Hz
Speaker rotation speed when SPEED is set to FAST.
DRIVE 0—100
Overdrive depth. Raising this value will produce stronger distortion.
Parameter name Range Explanation
MIX BAL. 0—100%
Balance between the original sound and effect sound. At a setting of 0% only the original sound
will be output; at a setting of 100% only the effect sound will be output.
ACCEL 0—10
Rate of acceleration when switching between rotation speeds (SLOW, FAST). With higher settings,
the transition between speeds will occur more quickly. Since an actual rotary speaker must acceler-
ate or decelerate an object (the speaker) that has a given amount of mass, a certain length of time is
required for the change to occur. This parameter simulates this phenomenon.
LOW 0—100
Low-frequency output level. Raising this value will boost the low-frequency range.
HIGH 0—100
High-frequency output level. Raising this value will boost the high-frequency range.
