What fm1-midi-bridge does

  • This firmware replaces the synth engine and makes the FM-1 a bridge between its TRS input, USB and Bluetooth.
  • Every route can be switched off, filtered or remapped to one channel, and told whether to pass clock and SysEx.
  • The 27 keys and the knobs send notes and control changes, with octave, channel and velocity set on the Keyboard page.
  • The Recorder captures incoming events with their timing and replays them to USB, Bluetooth or both, once or looped, as a scratch looper.
  • A clock master drives an arpeggiator or drum app from 20 to 300 bpm, with start and stop.
  • The MIDI log decodes what passes, the Composer sends single messages by hand, and Statistics reports what a connected device actually sends.
  • Four preset slots snapshot every setting, and changes store a second later and survive power cycles.
  • USB is class compliant with no driver, Bluetooth advertises as "FM-1 MIDI", host mode connects to a Bluetooth keyboard, and a browser editor sets everything.
