What Trireme does

  • Every note key, button and the four right-hand knobs can send any key, from letters and F-keys to Ctrl+C and Alt+Tab.
  • Media and mouse keys cover volume, play / pause, next / previous, mouse movement, buttons and the wheel.
  • Five layers give you keys that switch while held, for one press or until pressed again, plus layer-tap and mod-tap.
  • PRESETS steps through the layers and the screen always shows what each control does, since the printed labels no longer apply.
  • Press OCT+ to open the on-device editor and change any key, knob and light without a computer.
  • Vial edits macros, tap dance, combos and the timing settings, with the FM-1 appearing as FM-1 Keyboard.
  • Each button and key takes a light style per layer: off, dim, mid, on, breathe, blink or automatic.
  • The configuration is kept in the FM-1's flash and survives power cycles, and the device stays USB-MIDI as well.
