I'm looking for a way to get the difference between 2 input CVs. For example, CV1 = 1V, CV2 = 1.5V, Out = .5V
Ideally, it would work with negative output as well, CV1= 1V, CV2 = -2V, Out = -3V
I think what I'm looking for is a comparator but all the modules I find seem to have outputs that are either low or high when CV2 is compared to CV1. I'm not sure what the name is of what I'm looking for, or if there is a way to do it with modules such as Math?
