I based this oscillator model on All About Electronics' Exponential VCO article. I removed the exponential converter section and added some additional features. This module runs on 12V+.
CV1 - DC voltage for controling pitch
CV2 - Another DC voltage that can be added to CV2.
Audio Out - An audio signal. Can be a triangle wave, square wave, or a blend of the two. Level of each wave type is controlled by the Triangle and Square knobs.
Triangle - Controls the amount of triangle wave blended into the output signal.
Square - Controls the amount of square wave blended into the output signal.
CV2 Trim - Controls how much of CV2 is added into CV1. This can be used to make modulation signals more subtle.
