SUPER FILTER

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

Description
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
Amount of attenuation per octave
-36 dB: extremely steep
-24 dB: steep
-12 dB: gentle
Cutoff frequency of the filter
Increasing this value will raise the cutoff
frequency.
Filter resonance level
Increasing this value will emphasize the
region near the cutoff frequency.
Amount of boost for the filter output
On/off switch for cyclic change
How the cutoff frequency will be modulated
TRI: triangle wave
SQR: square wave
SIN: sine wave
SAW1: sawtooth wave (upward)
SAW2: sawtooth wave (downward)

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.
