What would happen if we made our Helauxy Duo Mini without switches? You'd get the Auxidi Converter!
Bring your own 2 button normally open aux switch, plug it into the Auxidi Converter, and it'll send out the same MIDI commands our Helauxy Duo Midi does (including dual-press mode!).
Flat on all sides so you can stuff it wherever. You don't necessarily NEED to see the 1/2 LED's.
Video Coming soon; In the mean time checkout the config doc!
