25: Rotary Speaker

25: Rotary Speaker

This effect simulates a rotary speaker which is essential to organ sounds. This size 1 Rotary Speaker effect is monaural. You can change the speed of speaker rotation via dynamic modulation. The effect also simu- lates the microphone settings.

a: Sw

 

This parameter sets how the rotation speed (slow and fast) is switched via the

 

 

modulation source.

 

When Sw = Momentary, the speed is usually slow. It becomes fast only when you keep the pedal depressed or hold the joystick in position.

When a value for the modulation source is less than 64, “slow” speed is selected, and when the value is 64 or higher, “fast” is selected.

When Sw = Toggle, the speed is switched between slow and fast each time you press the pedal or operate the joystick.

Each time the value of the modulation source exceeds 64, the speed is switched between slow and fast.

b:Horn Acceleration On a real rotary speaker, the rotation speed is accelerated or decelerated gradu- ally after you switch the speed. The Horn Acceleration parameter sets the speed at which the rotation is accelerated or decelerated.

d: Mic Distance

This simulates microphone settings, specifying the distance between the micro-

 

phone and rotary speaker.
