This project turns an Arduino into a "USB MIDI to Serial" bridge.
This way you can use USB to send MIDI data to the Serial port present on many 1990s MIDI modules.
This project also serves as a documentation of how Serial MIDI works.

- USB ↔ Serial MIDI bridge for Arduino Leonardo
It includes schematics and the Arduino project. It also contains a USB MIDI library supporting multiple MIDI input/output ports.pc-tools
- tools for Windows that I wrote while researching/testing MIDI playback via my PC's COM portSerialMIDI.txt
- documentation on how Serial MIDI works (port settings, protocol, etc.)
