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 matching 1.2 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. After Connect FM-1, edits affect the selected device. The live granular recording is not stored.

The living background responds to the selected page: sparse settings leave more space, larger grains draw longer forms, and increased modulation brings more movement. It is a guide to settings, not an audio waveform. Hold a function button to see its controls explained on the display. Tap to use it. EDIT: Sound → Filter → Envelope → Mix → Mixer.

EDIT + PRESET: sound preset. Every track can use every engine.

Begin with Blank or any factory Biome. Shape your six voices and phrases, then use GLO → User Banks to select one of 16 Biome slots or 64 sound slots. Enter a name, stop playback, choose internal clock and save. In browser mode, an occupied slot requires a second Save within three seconds. The live FM-1 editor instead asks you to confirm replacement. Browser banks stay in this browser; hardware banks stay on the FM-1. Export each finished Biome as a file for safekeeping. Granular audio is not stored.

GROWING THROUGH YOUR FEEDBACK

Thank you for listening.

Your response to Mutable Dreams has shaped this next chapter. Your requests for warmer sounds, personal Biomes and dependable performance are at the heart of version 1.2. Thank you for making music with it, and for telling us what could be better.

Every voice is yours.

Fill all six tracks with percussion, resonant strings, soft chords, or any combination. Choose from 288 sound presets while keeping your notes, rhythm, levels and sends. An empty Biome is a starting point for a world of your own.

Chance, with a memory.

Euclidean patterns, swing, accents and repeats meet eight shared scales. Lock a seed with ARP, make a variation with REC, and undo it with ENV. Freeze, reverse or transpose the granular cloud as your rhythm keeps moving.

Room to be clear.

Full-rate granular recording, gently overlapping grains and a cleaner signal path bring more detail. Open the filter for clarity or close it for warmth. Gentle resonance and fundamental-led presets keep softer sounds within easy reach. FULL and ECO offer different processing budgets. Automatic admission limits remain in place. The release passed 29 controlled FM-1 cases; dense patches may require ECO. See the qualification report for scope and limits.

VERSION 1.2 / SHAPED BY LISTENING

A gentler palette. More room to compose.

A calm walkthrough of the new voices, phrases and living interface, with actual firmware views and music rendered by the Mutable Dreams 1.2 engine. Thank you for helping this instrument grow.

VERSION 1.2 / YOUR NEXT CHAPTER

Keep your worlds. Explore new ones.

Start from the original M-VAVE Stock V15, or update Mutable Dreams following the matching backup instructions. Export saved User Banks as .mddb and unsaved live edits as JSON before updating. Connect only the intended FM-1 and disconnect the live editor before installation.

Install or return to V15 ↗ · Download firmware ↓ · GitHub release ↗

Update & recovery guide · Illustrated 1.2 guide · Complete source · Qualification & limits

Returning to V15 erases User Banks and preferences. Restore them from your separate backup after reinstalling Mutable Dreams; the device requires physical SEL confirmation. For 1.0, follow the legacy backup and qualified route through 1.1 described in the recovery guide. Other third-party update paths are not certified.

Browser 1.2 banks are separate from hardware and from the retained 1.1 browser. Export your older browser patches there, then import them here. Keep the original files for downgrades. USB MIDI is tested; physical TRS-MIDI cable testing remains outstanding.

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 ↗
