SUPER TINY MIDI TRICKS
MIDI TRS A&B USB-C Adaptor & Router
- The smallest USB MIDI adaptor you can buy
- So small that it fits perfectly in a GBA game case!
- Break off the sides to make it even smaller!
- Super easy web interface to program it. Route any channel to any other, pipe CCs, block messages, transpose, split, do mono/poly tricks, and way more!
- Configurable front button for on-the-fly panic, pitch bend, mod, octave, CC, or trigger note.
- 3 adjustable-brightness indicator lights gently fade in and out, rather than blinking distractingly.
- Works as a passive TRS MIDI A to B adaptor too (no power or usb needed when used this way)
- For all TRS & TS MIDI types (+ classic DIN jacks coming soon)
- Easy solder pads if you want to put it inside an old keyboard or something that you want to add USB MIDI to. Perfect module for mods! (4 GPIO pads too)
Easy to Program, Try It Out ➡
Aug 6, 2026 UPDATE:
The PCBs are in, and it works great! Right now, we have the full planned adaptor and router capability, but still testing for bugs.
The web tool to configure it as a router is now live HERE.
Next, I’m 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.
