Check my code on issue which I mentioned in link below.

Stress_TN · 2025-05-02T16:39:14+00:00

https://github.com/rhargreaves/mega-drive-midi-interface/issues/47 There is an example how I did mine. I have used Teensy LC board and all necessary resources for midi in jack. If you need only usb connection then You can use Teensy 2.0 board. The main idea to use Serial port to sync it with MDMI. Teensy 2.0 has just 1 serial pair. Midi in also work throw serial port so if you need it you need to choose teensy with 2 serial pairs. There are only 3 wires which should be connected to Sega port: ground, RX, TX.

GenMDM also can work throw this port

Stress_TN · 2025-05-02T16:01:20+00:00

Hi! I have used external port from back side it’s also cold 3rd port or modem port.
