A Biome replaces all six tracks and clears the cloud. Stop playback and SAVE your changes first. Factory Biomes remain available.

Two worlds, one instrument

Shape sounds here, or connect your FM-1 and edit it live. BROWSER

The browser and FM-1 keep separate User Banks. Connect with USB to use the hardware banks.

Hardware editing needs the 1.1 editor firmware and Web MIDI with SysEx (Chrome or Edge). Audio comes from the FM-1 while connected; the small display is a live parameter view. Export / Import below transfers one complete live Biome as a file. SAVE keeps it on the selected instrument. Full .mddb backups contain the saved project, preferences and all User Banks; unsaved live edits, granular audio and calibration are excluded. A full restore requires STOP, internal clock, and physical SEL confirmation. Save changes before backing up, or export the live patch separately.

Five new starting points

Stop playback before loading. These examples use the new bass, shared space and selected Elements voices. Start the instrument first.

02 / THE BROWSER EDITORChoose a sound · Keep your rhythm

Make this world your own.

All six voices, rhythms, filters and effects are playable here. Start the instrument, select a voice, then explore its pages.

Patch files keep your six voices, patterns and settings. Stop before importing. User Banks stores 16 Biomes and 64 sounds in this browser; export keeps as many files as you like. In BROWSER mode, edits stay in this browser. When connected, edits target the FM-1. The live granular recording is not stored.

THE 1.1 WALKTHROUGH / SHAPED BY YOUR FEEDBACK

Warmer worlds.
Your own Biomes.

Thank you for the music, thoughtful questions and generous feedback. Take a quiet tour of the new voices, mixer, shared effects, phrases and User Banks, then hear the granular bus on a real FM-1.

Music recorded directly from an FM-1 running this release. The film shows native Mutable Dreams 1.1 views rendered from the release source; it is not a camera recording of live editing. Calm generated male narration. Selected original Mutable Instruments algorithms retain their credits; this independent project is not endorsed by Mutable Instruments or M-VAVE.

MUTABLE DREAMS 1.1 / INSTALL & RETURN

Keep your worlds safe.

Update directly from Mutable Dreams 1.0 or install from the original Stock V15. The test report records the checked routes and exact firmware files. Use the backup procedure for your current version. On 1.1, back up saved banks as .mddb and export unsaved live edits as JSON; 1.0 uses the legacy guide. Returning to V15 erases User Banks and preferences; restore your backup after reinstalling 1.1.

The hardware editor shows live parameters; sound comes from the FM-1. Browser mode is a complete independent instrument with its own saved banks. Your downloaded firmware, source, recovery instructions and checksums are available together.

WITH GRATITUDE / OUR ROOTS

From a generous idea,
new worlds can grow.

Mutable Dreams owes its foundations to Émilie Gillet and Mutable Instruments. Their instruments and openly shared code made this exploration possible. Selected original algorithms from Plaits, Rings and the new Elements Strike subset form part of our sound engine, with their original credits and MIT notices preserved.

Our contribution is a six-voice instrument for the FM-1: editable Biomes, generative rhythms, a custom granular bus, and an interface that invites discovery. We want to carry that spirit of curiosity into something approachable, expressive, and unmistakably its own.

An independent community project, unaffiliated with and not endorsed by Mutable Instruments. These are selected algorithms, not complete module ports. Our granular bus and Round Bass are our own designs. Marbles-inspired remembered variation, Tides-inspired cyclic modulation and Warps-inspired ring blending are original implementations, not complete ports of those modules.

Mutable Dreams · Independent firmware for the M-VAVE FM-1. Selected DSP: Émilie Gillet / Mutable Instruments, MIT. Device platform and simulator: fm1-base / felucca-bsp, MPL-2.0. This browser runs the firmware sound engine; FM-1 performance is measured separately. Browser saves stay on this computer. 16 named User Biomes and 64 user sound slots; factory Biomes remain available. Export your finished Biomes as files for safekeeping. Granular memory: 2.97 seconds, mono PCM16 at 44.1 kHz, with stereo grains. ECO uses half-rate FM / VA / Harmonic voices. Read the measurements and limitations ↗
