01 / BIOME ATLASVelvet Mist168 Biomes + Blank ↗

A Biome contains the complete instrument. If you have unsaved edits, you can keep editing, open User Banks to save, or explicitly discard and load. Factory Biomes always 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 Mutable Dreams 1.5 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 Motion Sketches

Five editable examples of the new sequence and LFO controls. Start the instrument and stop playback before loading; save or export your current Biome first.

02 / THE BROWSER EDITORChoose a sound · Keep your rhythm

Make this world your own.

Six synth voices, or three synth voices and one Lo-Fi kit, 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.

GLO: Harmony → Journey → System → Look → MIDI → Banks. HOME + PRESET: Biome. EDIT + PRESET: sound preset. Every track can use every engine.

Begin with Blank or any factory Biome. Shape your synth voices, kit 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.

THE SOUND OF THE UPDATE

New worlds. A living signal.

Four contrasting sound worlds from the 1.5 native engine, with no narration or third-party music. The display views are captured from the firmware renderer.

GROWING THROUGH YOUR FEEDBACK

Thank you for listening.

You asked for Biomes that sound further apart, mute states you can read at a glance, more scales and independent MIDI control. Those requests remain in 1.5, alongside new Biomes and BLE MIDI. Thank you for making music with this instrument and telling us where it can grow.

Every voice is yours.

Use six freely assignable synth tracks, or switch to a kit with three synth tracks. The three dormant synth settings are kept when you change modes. Choose from 364 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 thirteen 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 qualification is documented separately. Dense combinations may require ECO.

VERSION 1.5 / NEW WORLDS

Twelve new places to get lost.

The atlas now holds 168 musical Biomes plus Blank and 364 tone starting points. Four stronger organic palettes follow the music on the FM-1 display. The original Biome IDs and User Banks remain in place.

Bluetooth MIDI reception has been verified on one physical FM-1 for notes, CC74 and transport clock. USB and TRS input remain available. A separate BLE-MIDI sender that the FM-1 connects to, external TRS hardware and the newer UC25HQ80 board still need physical verification.

VERSION 1.5 / DOWNLOAD & INSTALL

Your next world starts here.

Back up saved User Banks as .mddb and export unsaved live edits as JSON before updating. Use the browser installer with Chrome or Edge, or the Python kit. The installer also offers a return to original V15. Official M-UPGRADE rejects custom Mutable Dreams packages.

BLE reception was tested from a Mac. Linking the FM-1 to a separate BLE peripheral is experimental. Physical UC25HQ80 installation and TRS input remain unverified in this cycle. FM-1 only; no SMK-37 package is included.
