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

class="">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.</span></div>
