Can you wire two circuits into the same expression jack? Is that feasible or would each circuit require it's own in order to work correctly? I'm asking because I have a dual Bitquest and Dual Elements. Both can have two, but no room. This is one of my many ventures I just never attempted. lol
Don't those want a CV? (Which is to say, isn't the expression aspect a voltage divider working off of a supplied voltage reference). Yes, you can utilize a single jack for that, but you do not want to connect the different circuit points together, so a pair of unity gain DC coupled buffer amplifiers need to act as gatekeeper between the the outside world and the pair of circuits (or all four, if you're a madman).
One buffer is needed for each circuit input. If a reference voltage is provided
insure they measure the same voltage, if so disconnect one of them so only a single voltage reference is provided to the pot.
