I'm thinking of building a control voltage generator for a synthesizer. Basically I want to control two pitch control voltages with variable resistors, something like this:
R1 needs to control only the output of CV1, and R2 only the output voltage of CV2. But with my understanding, if one were to modify the value of R1 this would change the output voltage of CV2, which is obviously undesirable for a pitch control.
Two voltage regulators in parallel seems like overkill for such a simple problem, and I'm not even sure it would work. Is there some other way to make it so that R2 will not affect the output of CV1 and that R1 will not affect the output of CV2?
also, apologies in advance if this is a duplicate question. It seems like a simple, common problem but I've searched quite thoroughly.
