This project adds USB-MIDI control to the Korg Monotron synthesizer.

A Trinket is installed inside with a micro-USB connector at the back.

A custom version of the uMIDI2CV is flashed on the Trinket.

The original function of the Monotron is unaffected when no USB is plugged in.

With USB plugged in the Monotron shows up as a MIDI device on the computer/phone/tablet without any special drivers.

The Trinket is connected to the AUX input and to the filter cutoff.
