25: Rotary; 26: Tremolo/Auto Pan - Roland V-Synth XT Owner's Manual

25: Rotary

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

Description
Simultaneously switch the rota-
tional speed of the low frequen-
cy rotor and high frequency
rotor
SLOW: Slows down the rotation
to the Slow Rate.
FAST: Speeds up the rotation to
the Fast Rate.
Slow speed (SLOW) of the low
frequency rotor
Fast speed (FAST) of the low fre-
quency rotor
Adjusts the time it takes the low
frequency rotor to reach the
newly selected speed when
switching from fast to slow (or
slow to fast) speed.
Volume of the low frequency ro-
tor
Slow speed (SLOW) of the high
frequency rotor
Fast speed (FAST) of the high
frequency rotor
Adjusts the time it takes the high
frequency rotor to reach the
newly selected speed when
switching from fast to slow (or
slow to fast) speed.

26: Tremolo/Auto Pan

This is a stereo tremolo or auto-pan effect. Tremolo cyclically
modulates the volume to add tremolo effect to the sound. The Auto
Pan effect cyclically modulates the stereo location of the sound.
