Biome Browser with family and preset controls
HOME · Biome Browser

Find a place to start.

A Biome holds the sounds, patterns, effects and modulation for the whole instrument.

  1. Press HOME until Biomes appears. K1 filters by family or Favorites.
  2. Turn K2 or PRESET to browse. Press SEL to load, then PLAY.
  3. Try the four Live Atlas macros. Use REC in the browser view on the FM-1 to mark a favorite, then stop and SAVE to keep it.

Six-track Sequencer Grid with individual pattern lengths
SEQ · Six-track grid

Let two patterns cross.

Two tracks with different pattern lengths can fall in and out of sync as they play.

  1. Tap SEQ until Sequencer / Grid. Use K1 for track, K2 for step, K3 for note and K4 for length.
  2. Choose lengths of 12 and 16. From the grid, SEL opens the selected track. REC cycles recording modes on its sequence page.
  3. Continue to Phrase Tools for copy, transpose and expression, or to Step Rules. While playing there, press SEL to queue a one-bar fill.
Living Links motion page with a hit assigned to pan
FX · Link Motion

Make the voices respond.

Use Living Links to let a hit move another voice. Biome Drift moves between two captured settings.

  1. On Living / Links, choose a source track, destination track and target. On Link / Motion, choose Hit and raise the depth from zero.
  2. To try Drift, set its mode to Off. In Drift / Scenes, capture A with K1, change a sound control, then capture B with K2. Try Manual first.
  3. For a simpler experiment, raise one track's grain send, open Granular Bus and turn Space up gently. LFO toggles grain freeze.

For hands-on control, MIDI Learn maps a knob or fader to a target. See page 5 of the PDF for a first mapping.

Pearl Fern's two-section factory Journey in Loop mode
SEQ · Journey Arrange

Give the piece a form.

Journey joins up to eight sections. An anchored voice can carry its sound and pattern across a transition.

  1. Start with Pearl Fern, Chapel of Fog or Copper Step and press PLAY to hear a factory loop.
  2. To make your own, stop and tap SEQ until Journey / Arrange. Set the mode with K1, section with K2, source with K3 and section count with K4.
  3. Tap SEQ for Timing, then Anchors. Set a duration and choose a track to carry. Save your version in a User Biome slot.

The other 269 factory Biomes, including Blank, start with Journey Off. Off retains the sections.

Firmware & tools

Bring it to your FM-1.

Mutable Dreams 2.1 is built for the M-VAVE FM-1.

Hardware coverage. Build 2467CC38 was tested on an FM-1 via USB-MIDI in both directions with Mutable Dreams 2.0 and with M-VAVE stock V15. The saved banks and live Biome matched their backups byte for byte after the V15 recovery. Mare Nebularum completed a scene transition in a two-minute test with eight USB audio channels and screen mirroring, with zero measured dropouts. A physical four-hour run, a separate stock V16 round trip and validation on UC25HQ80 (B36014) remain open for this exact build.

Before an update, export your saved banks as .mddb and export an edited live Biome separately. Use desktop Chrome or Edge for the USB installer and editor.
