MFX/IFX Parameters
42
06 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.
You can use MFX CONTROL to restart the step sequence from the
beginning (p. 10).

Parameter Value Explanation
Step 01–16 0–127 Cutoff frequency at each step
Rate Sync
(Rate (sync switch))
OFF, ON
If this is ON, the rate synchronizes with
the tempo of the rhythm.
& “Tempo” (p. 8)
Rate Hz (Rate (Hz)) 0.05–10.00 [Hz]
Frequency of modulation

& “Note” (p. 72)
Attack 0–127
Speed at which the cutoff frequency
changes between steps
Filt Type
(Filter Type)
LPF, BPF, HPF,
NOTCH
Type of filter
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
Filt Slope
(Filter Slope) -12, -24, -36 [dB]
Amount of attenuation per octave
-12 dB: Gentle, -24 dB: Steep,
-36 dB: Extremely steep
Filt Reso
(Filter Resonance)
0–127
Filter resonance level
Increasing this value will emphasize the
region near the cutoff frequency.
Filt Gain
(Filter Gain) 0–+12 [dB] Amount of boost for the filter output
Level 0–127 Output Level
07 ENHANCER
Controls the overtone structure of the high frequencies, adding
sparkle and tightness to the sound.

Parameter Value Explanation
Sens 0–127 Sensitivity of the enhancer
Mix 0–127
Level of the overtones generated by the
enhancer
Low Gain -15–+15 [dB]
Amount of boost/cut for the low-
frequency range
High Gain -15–+15 [dB]
Amount of boost/cut for the high-
frequency range
Level 0–127 Output Level
08 AUTO WAH
Cyclically controls a filter to create cyclic change in timbre.

Parameter Value Explanation
Mode
(Filter Type) LPF, BPF
Type of filter
LPF: The wah effect will be applied over a
wide frequency range.
BPF: The wah effect will be applied over a
narrow frequency range.
Manual 0–127
Center frequency at which the wah effect
is applied
Peak 0–127
Width of the frequency region at which
the wah effect is applied
Increasing this value will make the
frequency region narrower.
Sens 0–127
Sensitivity with which the filter is
modified
Polarity UP, DOWN
Direction in which the filter will move
UP: The filter will change toward a higher
frequency.
DOWN: The filter will change toward a
lower frequency.
Rate Sync
(Rate (sync switch))
OFF, ON
If this is ON, the rate synchronizes with
the tempo of the rhythm.
& “Tempo” (p. 8)
Rate Hz (Rate (Hz)) 0.05–10.00 [Hz]

& “Note” (p. 72)
Depth 0–127
Depth at which the wah effect is
modulated
Phase 0–180 [deg]
Adjusts the degree of phase shift of the
left and right sounds when the wah effect
is applied.
Low Gain -15–+15 [dB]
Amount of boost/cut for the low-
frequency range
High Gain -15–+15 [dB]
Amount of boost/cut for the high-
frequency range
Level 0–127 Output Level
