Playing

  • Keys play notes, F3 to G5, and the FM-1's own General MIDI sounds play them. OCT− / OCT+: an octave.
  • ENV held: sustain; tap it twice to lock it. LFO held: the mod wheel. REC: all notes off.
  • ALGORITHM MIDI channel, PRESETS program change (the sound follows), MASTER volume.

Pages

  • A button each: HOME Play, SEL Keys, ARP Arp, SEQ Sequencer, GLO Sound, EDIT Setup (tempo).

  • SELECT and FX step through the banks; hold FX to set their controller numbers.

Scales, arpeggiator, sequencer

MIDI

  • Pick a MIDI out port to play a synth or your DAW from this page (Chrome and Edge have Web MIDI).
