Hi John,

Yeah, many rotaries out there have moveable stops so the number of positions
can be changed. Unfortunately, I'm looking for something that is about 1/2"
in diameter and it would be nice if they were panel mount and $4 each (or
less). Most of the rotaries I've seen out there are 1" (or more) around, and
with the Odyssey controls spaced 3/4" apart, this obviously won't work.
Won't work very well in a 3U Blacet / PAIA style layout either. The Digi-Key
catalog shows some nice half-inch rotaries, but they're about $12 each.
Ouch!

Guess I'll have to go Uber-DIY and hand make my own. ;)

RE: Quadra-Boy. The ARP Quadra was a compromise synth shoveled out the door
in response to machines like the OB-X and the Prophet. It had a
microprocessor and membrane 'soft switches' that allowed users to store the
settings of the routing/selection switches. Unfortunately, the sliders were
NOT programmable and still had to be manually set. While the sound and
layering capabilities of the Quadra made it unique, it was basically a day
late and a dollar short.
 
RE: Feature Creep. It's tough to decide what to leave out! It can be MUCH
more of a challenge to design a synth within certain size and/or price
limitations. Makes me respect the Mini Moog and Odyssey even more for what
they managed to pack into a relatively small space.
