Odp: [sdiy] Level Headed

[Roman]

I use +/- for audio AND control. Not limited to 5V. Filter output can swing to +/-10V
while oscillating, and multiple control voltage can reach that too when added.
I keep raw signals like oscillators and envelopes in +/-5V rails, but wouldn't mind
having a module with, say, -6.5..+8.3V output range.
I think most common is control voltage not going below 0, but I'm the freak here. ;)

  Hello All,

   

  Just a quick, but very basic question:

   

  What sort of levels do most modulars use for CV and audio? From what I've seen, it looks like +/-5V for audio, and 0 to +10V for control voltages. If so, I think I can see the reasoning behind it (positive and negative swings allow audio signals to add and subtract from each other, while keeping CVs positive only makes it easier to build something like a keyboard by just using a resistor divider chain and a bunch of switches), but I'm more than willing to admit I'm not really 100% sure.
