3. Turn up Filter Keytrack to +100% to have
Filter Cutoff change with equal-tempered
scaling.
4. Set Cutoff to 23, 35, 47 or 59 to have it
oscillating in the same pitch as the
oscillator´s usually tuning. 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 briefly. The filter
then oscillates to produce the resulting tone.
