[sdiy] FET to short pedal input?

[el macaco]

I soldered the fet up to test and my midi 2 cv converter has issues.  Seems like a bad contact on the midi in, will report back when I can test it all out.

And don't forget the bipolar level shifting for the 4066 control signal

+1 agree, absolutely this. 4066 or similar is simple and obvious. The only thing preventing it working is the power requirement.

Frankly, I suspect that the goal of not providing independent power to this interface circuit is making it much more difficult. Personally, I would build a small circuit board to fit inside the ARP Odyssey and pull power from the synth. Then, all voltages would surely fall within the workable range for a 4066.
