Minimoog filter question

[Martin Czech]

:::The Capacitors that couple the signal into the diff amp at the top of the 
ladder (.22uF on the schematic I've seen of the model D mini) need to be larger, 
they limit the frequency response. Also the 10uF that couples the resonance pot 
could be bigger. Check the archives this was discussed in detail, including 
clones that oscillate at low frequencies vs clones that don't.


righto, reducing the feedback for low frequency gives more bass
when resonance is turned on ->fatness.

Proposal: fat switch, toggles between a larger and a smaller cap.

works also for state variable designs (the other way arround,
of course, because more feedback in state vars means more
stability, or real poles, so it is a capacitive divider
what's needed there, a lowpass, whereas the moog needs a 
highpass)

all from my head...
