A wider atlas
Thank you for shaping this little instrument with us. Mutable Dreams one point four opens forty-eight new Biomes, each an invitation to find a different sound.

Move from stillness to motion
Turn the preset wheel. The next world can be a pulse, a bass line, or a wide, resonant space. The existing Biomes and your saved worlds stay in place.

See what is playing
A small request made the Home screen clearer. Muted tracks now fade across their whole row and meter, with a clear muted label.

New paths through harmony
Five new scales bring unfamiliar colour to your sequences and chords. Try Ukrainian Dorian, Harmonic Minor, or either of the Double Harmonic modes.

Each track, its own conversation
Give every track its own MIDI channel, share a channel, or turn note input off. Play it on the F M one, or open the full instrument and live editor in your browser. Thank you for keeping these worlds moving.
