Multi-Effects List
Effects
03: ENHANCER
Controls the overtone structure of the high frequencies, adding
sparkle and brightness to the sound.
fig.MFX03
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
05: LOW BOOST
Boosts the volume of the lower range, creating powerful lows.
fig.MFX05
06: SUPER FILTER
This is a filter with an extremely sharp slope. The cutoff frequency
can be varied cyclically.

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

range will be boosted

Parameter Value Description
Filter Type LPF, BPF,
HPF,
NOTCH Filter type
Frequency range that will pass
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,
-36 dB Amount of attenuation per octave
-36 dB: extremely steep
-24 dB: steep -12 dB: gentle
Filter Cut-
off #1 0–127 Cutoff frequency of the filter
Increasing this value will raise the
cutoff frequency.
Filter Reso-
nance #2 0–127 Filter resonance level
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-
tion Sw OFF,ON On/off switch for cyclic change
Modula-
tion Wave TRI, SQU,
SIN,
SAW1,
SAW2 How the cutoff frequency will be
modulated
TRI: triangle wave
SQR: square wave
SIN: sine wave
SAW1: sawtooth wave (upward)
SAW2: sawtooth wave (down-
ward)
Rate 0.05–10.0
Hz, note Rate of modulation
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.
