Roland V-Synth owner manual Rotary, Tremolo/Auto Pan, 129

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.

Parameter	Value	Description
Speed	SLOW, FAST	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.
Low Slow Rate	0.05–10.0 Hz,	Slow speed (SLOW) of the low
	note	frequency rotor
Low Fast Rate	0.05–10.0 Hz,	Fast speed (FAST) of the low fre-
	note	quency rotor
Low Accelera-	0–15	Adjusts the time it takes the low
tion		frequency rotor to reach the
		newly selected speed when
		switching from fast to slow (or
		slow to fast) speed.
Low Level	0–127	Volume of the low frequency ro-
		tor
Hi Slow Rate	0.05–10.0 Hz,	Slow speed (SLOW) of the high
	note	frequency rotor
Hi Fast Rate	0.05–10.0 Hz,	Fast speed (FAST) of the high
	note	frequency rotor
Hi Acceleration	0–15	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.
Hi Level	0–127	Volume of the high frequency
		rotor

Ps Hi Gain	-15– +15 dB	Gain of the high range

Effects List

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.
