Mutable Dreams 2.0 — From a Biome to a piece

Mutable Dreams is a free, open-source six-track instrument for the M-VAVE FM-1 by Kid Bunka. Start with a Biome, let its patterns evolve, then arrange and record the moments you want to keep.

• Journey Arranger links up to eight sections and can carry a voice between them. Chapel of Fog, Pearl Fern and Copper Step include a factory loop. The other 269 entries start with Journey Off.
• Six-track Sequencer Grid with individual pattern lengths, keyboard recording, accents and gate lengths, phrase tools and one-bar fills.
• Living Links, Biome Drift and MIDI Learn for movement between tracks and hands-on external control.
• USB audio at 44.1 kHz with the stereo mix on inputs 1–2 and six pre-pan, pre-effects mono voices on inputs 3–8. Mute the local speaker and headphones while USB stays active.
