   One Slope / Resonance pot:
   ccw end is 6dB/Oct, 12 o'clock position is 24dB/Oct, with
   practically linear action in between. Turning the knob further
   clockwise will keep the 24dB/Oct slope, but also adds resonance.

Very interesting!  A variable slope feature on a HPF could be
extremely useful.  

Hmmm... do you implement the variable slope feature by offsetting the
tuning of the individual stages?  Or do you pan between taps at the
outputs of the individual stages?
