07: AUTO WAH

The Auto Wah cyclically controls a filter to create cyclic change in

timbre.

Parameter	Value	Description
Filter Type	LPF, BPF	Selects the type of filter.
		LPF: The wah effect will be ap-
		plied over a wide frequency
		range.
		BPF: The wah effect will be ap-
		plied over a narrow frequency
		range.
Rate #	0.05–10.00 [Hz]	Adjusts the frequency of the
		modulation.
Depth	0–127	Adjusts the depth of the modu-
		lation.
Sens	0–127	Adjusts the sensitivity with
		which the filter is controlled.
Manual #	0–127	Adjusts the center frequency
		from which the effect is applied.
Peak	0–127	Adjusts the amount of the wah
		effect that will occur in the area
		of the center frequency. Lower
		settings will cause the effect to
		be applied in a broad area
		around the center frequency.
		Higher settings will cause the ef-
		fect to be applied in a more nar-
		row range.
Level	0–127	Adjusts the output level.

08: 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
High Slow	0.05–10.00 [Hz]	Adjusts the slow speed (SLOW)
		of the high frequency rotor.
Low Slow	0.05–10.00 [Hz]	Adjusts the slow speed (SLOW)
		of the low frequency rotor.
High Fast	0.05–10.00 [Hz]	Adjusts the fast speed (FAST) of
		the high frequency rotor.
Low Fast	0.05–10.00 [Hz]	Adjusts the fast speed (FAST) of
		the low frequency rotor.

Adding effects

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 specified speed (the Low
		Slow/Hi Slow values).
		FAST: Speeds up the rotation to
		the specified speed (the Low
		Fast/Hi Fast values).
		* When you want to use the ped-
		al switch to switch the Rotary ro-
		tation speed, select MFX
		PARAMETER1 in Pedal Control
		Assign (p. 90).
High Accel	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.
		Lower values will require long-
		er times.
Low Accel	0–15	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.
		Lower values will require longer
		times.
High Level	0–127	Adjusts the volume of the high
		frequency rotor.
Low Level	0–127	Adjusts the volume of the low
		frequency rotor.
Separation	0–127	Adjusts the spatial dispersion of
		the sound.
Level #	0–127	Adjusts the output level.

09: COMPRESSOR

The compressor flattens out high levels and boosts low levels,

smoothing out unevenness in volume.
