good points

thats a shame, it would be fun to have a version of this in the Chameleon..

I dont, I want it...

in its simplest form its four 6dB/oct lowpass filters, with the resonance
taken from the 4th stage and fed back into the input (via some gain
control).
However there's a lot more in there, as the 4 pole interact with each other,
and you also get some non-linear things going on when you overdrive it..
