This is a filter with an extremely sharp slope. The cutoff frequency can
be varied cyclically.
fig.MFX-05
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.MFX-06
Controls the overtone structure of the high frequencies, adding sparkle
and tightness to the sound.

05: SUPER FILTER
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 re-
gion 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
Cutoff
0–127
Cutoff frequency of the filter
Increasing this value will raise the cutoff
frequency.
Filter
Resonance
0–127
Filter resonance level
Increasing this value will emphasize the
region near the cutoff frequency.
Filter Gain 0– +12 dB Amount of boost for the filter output
Modulation Sw OFF,ON On/off switch for cyclic change
Modulation
Wave
TRI, SQR, 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 (downward)
Rate
0.05–10.00 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.
