DIY-MIDI-to-CV

This is a DIY and open source MIDI to CV interface. It lets you use midi keyboards, loopers or computers to control all kinds of CV based synthesizers.

Known Issues with PCB!

1. DAC data lines are not connected

Solution: the connector in the middle of the board has the data lines so I ran wires from there to the arduino pins

2. pin numbers were mostly all wrong lmao

tldr: a button group and one dac use the same pin

Solution: remove input side of diode 3 and connect to pin 9 of arduino

Code

very much a work in progress.

Libraries needed: Arduino MIDI Library by Francois Best https://github.com/FortySevenEffects/arduino_midi_library
