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
08: AUTO WAH
A filter that turns on and off to create a cyclical change in timbre.

Parameter Value Description
Rate #1 0.05–10.00 Hz,
note Rate of modulation
Attack 0–127
Speed at which the cutoff frequency
changes between steps
Filter Type #2 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 cut-
off
HPF: frequencies above the cutoff
NOTCH: frequencies other than the re-
gion of the cutoff
Filter Slope
-12, -24,
-36 dB
Amount of attenuation per octave
-12 dB: gentle
-24 dB: steep
-36 dB: extremely steep
Filter Resonance
#3
0–127
Filter resonance level
Increasing this value will emphasize the
region near the cutoff frequency.
Filter Gain #4 0– +12 dB Amount of boost for the filter output
Level 0– 127 Output level
Step 01–16 0–127 Cutoff frequency at each step

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 nar-
row frequency range

note
Frequency of modulation
Depth #4 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 #2 0–127
Adjusts the amount of the wah effect that
occurs in the range of the center frequen-
cy.
Set a higher value for Q to narrow the
range to be affected.
