Pitch to CV, Envelope Followers and Gates might be of use.
I saw something about envelope followers online. It seems like that ought to do it, with some manual adjustments as always. Pitch to CV I would love to do, I have no idea how. Also, a friend suggested generating PWM from my serial port and filtering it. I don't know exactly how a Moog's PWM works, but from his description I thought I might just as well generate sine, ramp, square, triangle and pulse waves in Pd and run them through the filters and envelopes on the synth. And where's the fun in that? But if no other possibilities work out, I can use that.
That is one classic Moog there - the guy who did the refurb makes some great synth gear himself. Make good use of it.
You mean http://www.discretesynthesizers.com/arptronics/satis.htm ? That's my freshman theory and current acoustics teacher standing between Bob Moog and Tom Porett. He says he was friends with Dr. Moog way back. He's never said, but I take it that's how my school ended up with the thing. I got lucky; freshman year it was not possible to even be in the same room with it, now I've been explicitly offered the chance to learn on it.

I'm writing a proposal for independent study at my school, and my goal is to take a few lessons in tuning from this microtonal composer, compose a piece using my Pd sequencer, and somehow use the output to drive the newly refurbished Moog at my school (supposedly one of the first 5 Moogs ever made) to create a finished track.
MIDI-to-CV converters are expensive, and of course MIDI is already inadequate. So I'm thinking of circuits I've looked at before and wondering if plain old audio from [sig~] objects could be made to represent voltage, from -1 to 1, or 0 to 1 with -1 being off, and externally converted to the proper scale for CV input to the Moog. The music tech supervisor has added a module that makes the thing polyphonic, which I suppose I'll have to understand to do it. I guess my other option is to just use audio output, and process it through the Moog's modules.
Can anyone make any suggestions? How can one interface between Pd and control voltage? Could I jury-rig regular audio output to do it?
Thanks.
