Good to know

  • First sound: hold black key 2 (C) and run a finger across the white keys.
  • The strings keep the last chord, so you can let go of the black key and still strum.
  • With the rhythm on and Auto bass on, a held chord is played by the rhythm, not as one long note.
  • PRESETS transposes, and the chord names on screen move with it: set your key there.
  • FoMni autosaves about 4 seconds after a change, once the rhythm is stopped and all is quiet. A dot in the header means unsaved changes.
  • MIDI in: channel 1 notes pluck the nearest string, a chord on channel 2 becomes the chord, MIDI clock sets the tempo (EXT).

A community cheat sheet by the hub, not by the firmware's makers: when in doubt, their manual is right.
