Brett has put together a ten-minute video guide to using USB MIDI with Teensy. The succinct presentation shows how to interface a classic 5-pin MIDI DIN connector to a modern Digital Audio Workstation (DAW) — in this case, Cakewalk — using Teensy’s USB MIDI capabilities.

Brett details the code for both sending and receiving MIDI data, allowing recording of a MIDI device to a DAW, and playback from the DAW to the device. Brett points out that such an interface could just be purchased “for a tenner,” but what would be the fun in that? Moreover, this basic project can serve as the foundation of all kinds of MIDI tools and contraptions. Complete instructions, as well as code, can be found in the video below.
