Subject: RE: [ModularSynthPanels] Magic Smoke Mankato VCF design

I think it would fit handily on 2U with standard spacing and pots if you
didn't include an input mixer or the AC/DC switch. You'd only ever want DC
coupling if you're filtering slow control signals, which is unusual, though
I have once or twice wanted a CV lowpass. If you wanted to keep it you could
put it on the edge between pots and jacks the way some of the smaller MOTM
modules do. I'm not familiar with this filter but I presume having +/-
outputs for all its stages is the point of it?

Pots:

CoarseInput
FineFM1
ResFM2

Jacks:

In1VFM1FM2
6+12+18+24+
6-12-18-24-

Nice layouts, Dave. Oh, to have enough space for the 3U panel...

I'd take smaller knobs over tighter jack spacing, myself, but I know
how personal these issue are.

Have you considered sacrificing the FM2 input attenuator to make more
room for jacks? Basically, the jack field of "Encore knob" jacks with
6 MOTM-spec knobs.

Wait until you see STG's layout, it's a kicker! (But it is for
Moog/dotcom -- MOTM is a tad too narrow for it.)

I have a mix of dotcom and MOTM, so I will probably opt for STG's
dotcom panel. Nice to know that there will be an MOTM alternative, though.
