03: ENHANCER

Controls the overtone structure of the high frequencies, adding

sparkle and brightness to the sound.

L in					2-Band	L out
	Enhancer		Mix		EQ
R in					2-Band	R out
	Enhancer
			Mix		EQ
Parameter		Value		Description
Sens #1		0–127		Sensitivity of the enhancer
Mixl #2		0–127		Level of the overtones generated by
				the enhancer
Low Gain		-15– +15 dB		Gain of the low frequency range of
				frequencies
High Gain		-15– +15 dB		Gain of the high frequency range of
				frequencies
Level		0–127		Output level

04: ISOLATOR

This is an equalizer that radically cuts the volume of selected frequencies, allowing you to create special effects cutting the volume in various ranges.

fig.MFX04

L in					L out
	Isolator		Low Boost
R in					R out
	Isolator		Low Boost
Parameter		Value		Description
Boost/Cut		-60– +4 dB		These boost and cut each of the
High				High, Middle, and Low frequency
Boost/Cut				ranges.
Middle #1				At -60 dB, the sound becomes in-
Boost/Cut				audible. 0 dB is equivalent to the
Low #2				input level of the sound.
AntiPhase		OFF, ON		Settings of the Anti-Phase function
Middle Sw				for the Middle frequency ranges.
				When turned on, a stereo copy of
				the sound is phase-inverted and
				added to the signal.
AntiPhase		0–127		Adjusts the level settings for the
Middle				Middle frequency ranges.
Level				Adjusting this level for certain
				frequencies allows you to lend
				emphasis to specific elements
				within a sound. (This is effective
				only for stereo source.)
Anti Phase		OFF, ON		Settings of the Anti-Phase function
Low Sw				for the Middle frequency ranges
Anti Phase		0–127		The parameters are the same as
Low Level				for the Middle frequency ranges.
Low Boost		OFF, ON		Turns Low Booster on/off.
Sw				This emphasizes the bottom fre-
				quencies to create a heavy bass
				sound.
Low Boost		0–127		Increasing this value gives you a
Level				heavier low end.
				* Depending on the Isolator and
				filter settings, this effect may be
				hard to hear.
Level		0–127		Output level

Multi-Effects List

05: LOW BOOST

Boosts the volume of the lower range, creating powerful lows.

fig.MFX05
L in	Low Boost		2-Band EQ		L out
R in					R out
	Low Boost		2-Band EQ
Parameter		Value		Description
Boost Fre-		50–125 Hz		Center frequency at which the
quency #1				lower range will be boosted
Boost Gain #2		0–12 dB		Amount by which the lower
				range will be boosted
Boost Width		WIDE,		Width of the lower range that
		MID, NAR-		will be boosted
		ROW
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

06: SUPER FILTER

This is a filter with an extremely sharp slope. The cutoff frequency can be varied cyclically.

R in			R out
	Super Filter
Parameter	Value	Description
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	-36 dB: extremely steep
		-24 dB: steep	-12 dB: gentle
Filter Cut-	0–127	Cutoff frequency of the filter
off #1		Increasing this value will raise the
		cutoff frequency.
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
Modula-	OFF,ON	On/off switch for cyclic change
tion Sw
Modula-	TRI, SQU,	How the cutoff frequency will be
tion Wave	SIN,	modulated
	SAW1,	TRI: triangle wave
	SAW2	SQR: square wave
		SIN: sine wave
		SAW1: sawtooth wave (upward)
		SAW2: sawtooth wave (down-
		ward)
Rate	0.05–10.0	Rate of modulation
	Hz, note
Depth	0–127	Depth of modulation
Attack	0–127	Speed at which the cutoff frequency
		will change
		This is effective if Modulation
		Wave is SQR, SAW1, or SAW2.
Level	0–127	Output level
