Table 10:
Comb Filter Cutoff settings
If you need other tunings, just keep in mind that
Cutoff
is changed in semitones, so if you increment
Cutoff
by
12
, the filter oscillates one octave higher and vice versa.
☞
To set up the Comb filter to produce a tone:
1.
Select either
Comb+
to produce a string-like tone or
Comb-
to produce a tube-like tone.
2.
Turn up
Resonance
to around
114
to
127
.
3.
Turn up
Keytrack
to
+100%
to have Filter Cutoff change with well-tempered scaling.
4.
Set
Cutoff
to
23
,
35
,
47
or
59
to have it oscillating in the same pitch as the oscillators are
usually tuned. Please note that
Comb+
oscillates one octave higher than
Comb-.
5.
Feed the Comb filter with a signal of any kind. The incoming signal’s pitch isn’t important
for the resulting tuning, but both pitch and timbre of the input signal affect the timbre of
the Comb filter output sound greatly.
Try to experiment with all kinds of input signals, i.e. different oscillator settings, noise,
combinations of both and the like.
Also try to set up envelopes to control the levels of the input signal, i.e., use a short percussive
signal that only triggers the comb filter shortly. The filter then oscillates to produce the final
tone.
