I really like the way it sounds, and I think it adds more virsitility to
an already virsitile instrument....

Although is this a butterworth filter? 
also I don't have the schem's infront of me but if you reploaced the 22K 
resistor that comes from pin #9 Ic17, with a smaller value, could you get 
more resonance?
also, is it possible to replace the 100 ohm resistor (I think it was 100 
ohm) in the attack segment of the adsr eg for a quicker attack? or does 
it need some resistance there, (I mean when the pot is at min resistance)
thanks
