MIDI to CV Conversion Using a Livid BrainV2 and I2C Protocol

Bob Moog developed Control voltage (CV) in the 1960s. His introduction of CV called for an oscillator’s pitch to vary at the rate of 1 volt per octave. This scheme is widely used today in analog circuits, and can be mimicked digitally. The CV output is determined by converting various MIDI messages including USB MIDI, and physical controls including analog potentiometer inputs and momentary on, momentary off buttons. The Livid BrainV2 handles all the MIDI inputs and directs them to a digital to analog converter to create the CV signal controlled by I2C communication. This paper documents the hardware used to create the converter, the mathematical onsiderations for conversion, and techniques used to overcome the limited ability of 8-bit MIDI messages to be portrayed as an analog signal.
