interesting.... I'll do some research into how to invert a signal...
I think I was just wondering if you were to pump the output audio signal (or more precisely tap a bit of the audio signal with a simple passive mixer) into the 'cv in' of the phat philter would it affect it in a desirable kind of envelope kind of way?...
if routed in a certain way it would also sort of form a kind of feedback loop which would probably make it tend towards either silence or ridiculous audio destruction. Make sense?
(Im quite prepared to cast into the noob dungeon on this one!)
....................
One mod i have planned that im pretty confident will be success is swap out the low, mid, high octave select for a drag contact jobby ala gijs (

By the way this is all speculative. I havent even plugged it in yet!
And on that note I recon I'll go fire it up!
