Hmmm, for a modular synth I'd say constant amplitude is desirable. (In case
the moog is your only VCF in that synth.) I.e. for FM-stuff or analog
drums. In getting that mini-sound I'd (now that I know more about it) say
AC coupling is the way.
I think the suggestion of Sean is the way. A filter that can be switched
from micro to mini. The 10uF cap on the resonance pot doesn't contribute
much to the effect, I checked that by increasing it's value.

(?!?) Jeez, I wish I was as productive like you!
