SUPER TINY USB MIDI ADAPTOR
MIDI TRS A&B USB-C Adaptor & Router
- The smallest USB MIDI adaptor you can buy
- For all TRS MIDI types (+ classic DIN jacks coming soon)
- Works as a passive TRS MIDI A to B adaptor too (no power or usb needed when used this way)
- Web interface to program it to route any channel to any other, transpose, and more! (coming soon)
- Configurable front button, defaults as a panic button (coming soon)
- Break off the sides to make it even smaller!
- Easy solder pads if you want to put it inside a keyboard or something you want to add USB MIDI to.
So small that it fits perfectly in a GBA game case!
3 indicator lights gently fade in and out so they don’t blink distractingly. They will also soon allow adjustable brightness.
July 24, 2026 UPDATE:
The PCBs are in, and it works great! Right now, we have full adaptor capability. The web tool to configure it as a router is in progress. I’m also working on an enclosure with built-in classic DIN midi jacks, and the board already has pads for these.
Contact me for a free first-run unit in exchange for a social media post or a video review I can share.
