Multi-Effects List

07: STEP FILTER

This is a filter whose cutoff frequency can be modulated in steps. You can specify the pattern by which the cutoff frequency will change.

fig.MFX07

L in	Step Filter		L out
R in			R out
	Step Filter
Parameter	Value	Description
Rate	0.05–10.00	Rate of modulation
	Hz, note
Attack #1	0–127	Rate at which the cutoff frequency
		will change between beats
Filter Type	LPF, BPF,	Filter type
	HPF,	Frequency range that will pass
	NOTCH	through each filter
		LPF: frequencies below the cutoff
		BPF: frequencies in the region of
		the cutoff
		HPF: frequencies above the cutoff
		NOTCH: frequencies other than the
		region of the cutoff
Filter Slope	-12, -24,	Amount of attenuation per octave
	-36 dB	-12 dB: gentle
		-24 dB: steep
		-36 dB: extremely steep
Filter Reso-	0–127	Filter resonance level
nance #2		Increasing this value will empha-
		size the region near the cutoff fre-
		quency.
Filter Gain	0– +12 dB	Amount of boost for the filter output
Level	0– 127	Output level
Beat	0–127	Cutoff frequency for each 16th note of
1-1–4-4		a 4/4 measure
		* This can be set using the sliders of
		the part mixer.

08: AUTO WAH

A filter that turns on and off to create a cyclical change in timbre.

L in			L out
	Auto Wah
R in			R out
Parameter	Value	Description
Filter Type	LPF, BPF	Type of filter
		LPF: The wah effect is applied
		over a wide frequency range.
		BPF: The wah effect is applied
		over a narrow frequency range
Rate #2	0.05–	Frequency of modulation
	10.00 Hz,
	note
Depth	0–127	Depth of modulation
Sens	0–127	Adjusts the sensitivity with which
		the filter is controlled.
Manual #1	0–127	Adjusts the center frequency at
		which the effect is applied.
Peak	0–127	Adjusts the amount of the wah ef-
		fect that occurs in the range of the
		center frequency.
		Set a higher value for Q to narrow
		the range to be affected.
Level	0–127	Output level

09: HUMANIZER

Adds a vowel character to the sound, making it similar to a human

voice.

L in						L out
	Overdrive	Formant		2-Band		Pan L
					EQ	Pan R
R in
						R out
Parameter	Value		Description
Drive Sw	OFF, ON		Turns Drive on/off.
Drive	0–127		Degree of distortion
			Also changes the volume.
Vowel1 #1	a, e, i, o, u		Selects the vowel.
Vowel2 #2	a, e, i, o, u
Rate	0.05–10.00		Frequency at which the two vowels
	Hz, note		switch
Depth	0–127		Effect depth
Input Sync	OFF, ON		Determines whether the LFO for
Sw			switching the vowels is reset by the
			input signal (ON) or not (OFF).
Input Sync	0–127		Volume level at which reset is ap-
Threshold			plied
Manual	0–100		Point at which Vowel 1/2 switch
			49 or less: Vowel 1 will have a
			longer duration.
			50: Vowel 1 and 2 will be of equal
			duration.
			51 or more: Vowel 2 will have a
			longer duration.
Low Gain	-15– +15 dB		Gain of the low frequency range
High Gain	-15– +15 dB		Gain of the high frequency range
Pan	L64–63R		Stereo location of the output
Level	0–127		Output level

10: PHASER

Adds a phase-shifted sound to the original sound, producing a swirling modulation that creates spaciousness and depth.
