To make it sound like my MS20 i keep the input volume down to about
25%...higher values will sort of "crush" away the resonance (which
sounds cool too, just different to my korg). Obviously also keep the
CL pots fully anticlockwise. 

This filter is definitely a killer for ruff, electric stuff; it is one
of those filters where the resonance doesn't "sit on top" of the sound
but becomes an integral part of it-->very nice.

Check out a fixed filter bank in the feedback loop....muhahaha ;)
