16: ROTARY

The Rotary effect simulates the sound of the rotary speakers often
used with the classic electric organs. Since the movement of the high-
range and low-range rotors can be set independently, the unique
characteristics of these speakers can be simulated quite accurately.
This effect is most suitable for electric organ Patches.

Parameter Value Description
Tweeter 0.05– Slow speed (SLOW) of the high-fre-
Slow Rate 10.00 Hz quency rotor
Woofer 0.05– Slow speed (SLOW) of the low-frequen-
Slow Rate 10.00 Hz cy rotor
Tweeter 0.05– Fast speed (FAST) of the high-frequen-
Fast Rate 10.00 Hz cy rotor
Woofer 0.05– Fast speed (FAST) of the low-frequency
Fast Rate 10.00 Hz rotor
Speed #1 SLOW, Simultaneously switches the rotational
FAST speed of the low frequency rotor and
high frequency rotor.
Tweeter 0–15 Adjusts the time it takes the high frequency
Accelera- rotor to reach the newly selected speed when
tion switching between fast and slow speeds.
Woofer 0–15 Adjusts the time it takes the low frequency
Accelera- rotor to reach the newly selected speed when
tion switching between fast and slow speeds.

17: HEXA-CHORUS

Uses a six-phase chorus (six layers of chorused sound) to give
richness and spaciousness to the sound.
