So VCAs are somewhat of a cornerstone of modular as far as I understood. Getting some helped me to understand some basic as to why that is the case but how do these work? As I find a lot of info on this topic still confusing I would really want to talk about my specific case:
I have 2 Doepfer 130-2 VCAs ( I thought the switch thingy could let me dodge the linear vs. exponential topic for now).
First topic: Gain
For the sake of simplicity, I have a Signal with a Value of 10 coming in so the gain gives me an output of 1 at 1, an output of 2 at 2, and so on. First of all, is that how it works, or am I making things up beginning from this point?
Second topic: CV
This is where my headache begins. What does CV exactly do? The CV knob is doing the same for the CV value as the Gain for the Input value I assume (so again at a CV Signal 10 gives me a CV of 1 at 1, a CV of 2 at 2. So how do these values get merged? Will the CV value be added to the Input (after gain) or is it a multiplication? Am I right to assume that a CV of 2 and an Input of 3 will get me to an output of 5 (or is it a multiplication and gets me an output of 6?). Is the output capped? As most stuff in modular works in a certain range it should be but where is that cap and will it "distort" or anything if pushed past?
Thanks for anyone willing to teach me.
