Step Filter; Enhancer; Auto Wah - Roland Groovebox MC-707 Reference Manual

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.

If this is ON, the rate synchronizes with the tempo
of the rhythm.

Frequency of modulation
Speed at which the cutoff frequency changes
between steps
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
Amount of attenuation per octave
-12 dB: Gentle, -24 dB: Steep, -36 dB:

Explanation
Type of filter
LPF: Produces a wah effect in a broad
frequency range.
BPF: Produces a wah effect in a narrow
frequency range.
Center frequency at which the wah effect is
applied
Width of the frequency region at which the
wah effect is applied
Increasing this value will make the frequency
region narrower.
Adjusts the sensitivity with which the filter is
controlled.
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.
If this is ON, the rate synchronizes with the
tempo of the rhythm.
& "TEMPO" (p. 52)"TEMPO" (p. 52)"TEMPO"

Modulation frequency of the wah effect
Depth of modulation
Adjusts the degree of phase shift of the left
and right sounds when the wah effect is
applied.
