Moog Mother-32: MIDI to Quad DAC CV Control




An example of using two MCP4922 that are controlled via MIDI. The four DAC channels are used to control filter frequency, filter resonance, LFO frequency and VCA modulation. 

In Ableton Live, four LFO generators are used to send MIDI continuous controller data out to the Teensy, which in turn then uses the data to set the DAC voltage level of the MCP4922 chips via the SPI bus.
