About

Felucca turns the FM-1 into a multi-engine instrument: FM, virtual analogue, phase distortion, samples, granular, drums and physical models, played across four tracks with a step sequencer, song mode and a modulation matrix.

Most other open FM-1 firmwares started as forks of it. The author publishes a web installer, a web editor and a browser emulator.

  • Back up your presets with the current firmware’s own export before installing.
  • Rescue: none documented for this firmware.
  • If something goes wrong, follow the recovery ladder.
  • Returns to stock through M-VAVE's M-UPGRADE.
