Hairless MIDISerial Bridge For Mac

Hairless MIDISerial Bridge is a useful application designed to makes it easy to connect serial devices (like Arduinos) to receive and send MIDI signals.

Launch “Hairless MIDISerial Bridge” by double-clicking the application. Plug in your serial MIDI device, if it’s not already.

Select Preferences from the menu and check that the serial settings look correct (defaults are 115200bps, no flow control.) Choose your serial port from the “Serial port” box.

Launch the music app that will be sending and/or receiving MIDI data. Set your music app to send or receive MIDI data, if it’s not enabled already. Select your app’s MIDI port from the MIDI dropdown (on Windows, set both sides to connect to the same MIDI Yoke virtual MIDI port.)

To disable the bridge, uncheck the “SerialMIDI Bridge” checkbox at the top of the window.
