Multi-Effects List

15: AUTO PAN

Cyclically modulates the stereo location of the sound.

L in					L out
	Auto Pan		2-Band EQ
R in					R out
	Auto Pan		2-Band EQ
Parameter		Value		Description
Modula-		TRI, SQR,		Modulation Wave
tion Wave		SIN,		TRI: triangle wave
		SAW1,		SQR: square wave
		SAW2		SIN: sine wave
				SAW1: sawtooth wave (upward)
				SAW2: sawtooth wave (down-
				ward)
Rate #1		0.05–10.00		Frequency of the change
		Hz, note
Depth #		0–127		Depth to which the effect is applied
Low Gain		-15– +15 dB		Gain of the low frequency range
High Gain		-15– +15 dB		Gain of the high frequency range
Level		0–127		Output level

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.

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.
				SLOW: Slows down the speed to the
				Slow Rate.
				FAST: Speeds up the speed to the
				Fast Rate.
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.
Tweeter	0–127		Volume of the high frequency rotor
Level
Woofer	0–127		Volume of the low frequency rotor
Level
Separation	0–127		Stereo width of the sound
Level #2	0–127		Output level

17: HEXA-CHORUS

Uses a six-phase chorus (six layers of chorused sound) to give

richness and spaciousness to the sound.
