From the project
Version 3 of my stereo VCA in Kosmo format
- 2 channels, A and B - 2 CV inputs per channel, each one with its own attenuverter knob - Unipolar control voltage: 0V means VCA is fully closed (gain = 0), +10V means completely open (gain = 1) - 1 offset knob per channel, useful to bias bipolar CV signals like those from LFOs - The offset setting and attenuverted CV inputs of each channel are summed - Toggle switches to select between pan/balanced/tremolo mode, and clipping/distortion - Pan mode: output volue of both channels is halved. Pan CV signal will increase one channel's volume and decrease the other's simultaneously. - Balanced…
