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.
