rm,
thanks for the clarification. i do like the sound of those
sallen-keys then! somehow the idea that they're diodes got
planted into my brain..not sure how.
so i guess in this case i think i'd like to look into finding
something that uses cheap sallen-keys innards (or something)
that helps make these nice fizzy, foamy, band pass sounds.
obviously there's more to getting that smoothness than just a
HP/LP-in-series.
not sure, but it sounds like the sallen-key(s) in the ms20 must
have a fairly gentle filter slope..anyone know for sure
the resonance of each filter comes on so nicely without being
overbearing..
