On both Emu and Arp 2500 state variable filters, I've seen a second Q
control. On the Emu, it's called "Final Q" or something like that. On the
2500 1047, it's called "Keyboard Percussion". At least in the Arp's case, it
seems to be a way to introduce some ringing into the filter in response to a
gate.
Has anyone played with either of these? If so, is it a cool thing, and would
it be a desirable feature for a MOTM state variable filter?
