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.

Description
Rate of modulation
Speed at which the cutoff frequency
changes between steps
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
Amount of attenuation per octave
-12 dB: gentle
-24 dB: steep
-36 dB: extremely steep
Filter resonance level
Increasing this value will emphasize the
region near the cutoff frequency.

Description
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
Frequency of modulation
Depth of modulation
Adjusts the sensitivity with which the filter
is controlled.
Adjusts the center frequency at which the
effect is applied.
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.
