Think of it as more of a VCO than a filter.
BTW, I just uploaded another sound file (MP3 this time) and the only
knob I twiddled was the fine tune. I fed the signal input with a VCO
(squarewave) and the internal signal (Q1 pad) into IN2. Both Filter
and VCO frequency controlled by a sequencer (a CGS07/CVS42) so that
they are tracking. Bandwith set maximum, damping set to minimum. I
slowly swept the Fine Tune upward, and switched the internal signal to
Q2 abd Q3 at the very end.
