4 Channel Effects
07 Rotary Speaker (Rotry)
This is a simulation of a rotary speaker
(invaluable for organ sound). It
includes faithful simulations of the
delicate differences in coloration
produced by the direction of the
speaker's horn. By using TAP (or
MIDI) you can change the speed
externally.
z
A real rotary speaker is composed of
two rotating speaker cabinets (one high-
band and one low-band). Since both
cabinets have a different inertia, the
slight difference in time required for
each cabinet to speed up or slow down
creates distinctive sonic undulations
when the speed is changed. This effect
simulates these undulations. Therefore,
making small changes to the Speed
parameter while playing will create a
more organ-like sound. Adjust the Speed
Ratio to obtain the sound you desire.

Range Comments
On, Off Turns the effect on or off.
Slow, Fast Selects the rotation speed of the rotary speaker.
0 ~ 100 Determines the depth of the effect. Larger values create a deeper effect.
0 ~ 100 Sets the overdrive distortion. Larger values produce louder and more grungy
distortion.
0 ~ 100 Sets the noise level. Adding some noise is a good way to create a more realistic
effect.
0 ~ 100 Adds the sound of the rotary speaker cabinet itself.
–20 ~ 20 Determines the ratio of the horn's (high-band) rotation speed to the rotor's (low-band)
rotation speed. Larger values create more distinctive rotary speaker undulations.
0 ~ 100 Determines the balance between the rotor (low-band) and horn (high-band). Larger
values shift the balance toward the horn.
0 ~ 100 Determines the balance between the dry (direct) sound and the effect sound. Larger
values increase the sound of the effect.
