Now that wasn't so bad, was it<g>?

Good one! May not be panel space enough for dedicated button per stage, but
I'm sure there's a solution that's fast and easy to use.

I think that the quantizer could also accomplish your trigger sequencer just
by quantizing to only 2 levels - zero and max voltage. Not sure what you
meant by "randomly spin wheels to come up with variations on a set-interval

Add Midi out to the list, then make it an optional add on so that you only
pay for it if you need it.

Last I heard was 7 spaces, 16 knobs - which would be 2 rows of 8, in
slightly less than current MOTM spacing. Could go to 3/4" knobs to maintain
finger room. This still doesn't leave tons of room for push buttons and leds
per stage, input set and output gate jacks per stage, VFD display, alpha
dial, extra programmable buttons, clock controls and jacks, etc!

My guess is that it will end up taking a full 10 spaces.

This is a great idea. Seems trickier to implement in CV/Gate land than in
MIDI land. If you just hook a seq. output to a VCO's pitch, then a rest is
not possible. You'd need something that provides a gate or trigger for every
stage that is NOT a rest, and gate the VCO with a VCA.

OK folks, David stepped up to the plate, now it's your turn!
