you could use the moogerfooger. the vc res on that is lush ;)

you can patch up vc resonance in any filter if you have the right
utility modules. i think it goes something like this:

filter audio out to multiple
one multiple out goes to vca and then mixer input 1
sound source to be filtered goes to mixer input 2
mixer out goes to filter audio in
cv to control res amount goes to vca cv in
second multiple out is your final audio output

it's basically a controlled feedback loop (which is essentially what
resonance is). of course if you invert the phase of the feedback path
you can do exciting things like turn your low pass filter into a hi
pass filter too!

hope that helped,
