LOOM-8 for the M-VAVE FM-1

LOOM-8 turns the M-VAVE FM-1 into a pocket groovebox: eight instrument tracks, each in its own colour, on ten engines (six synths: knit, rayon, jacquard, bellows, cane and voile; a sample player, a break slicer, a drum kit, and MIDI out to drive another synth), 85 factory presets; a 64-step sequencer with step tricks and parameter locks; players (arp, strum, hold); weave, which crosses two patterns (bar by bar, step by step, or one's rhythm with the other's notes); throws (momentary effects); a conductor track that moves the song through a progression; two send-effect tracks (the reverb with the PlayStation's reverbs among its modes), a mixer with EQ and a compressor on the master, scenes and a song. MIDI over USB, Bluetooth and the TRS jack, and as a USB MIDI host for a keyboard or synth (through a powered hub). Built on fm1-base and felucca-bsp, from Felucca by Leo Kuroshita (Hügelton Instruments), with X0X's sequencer discipline and Polly's menu paradigm.

Installing is at your own risk, though it's hard to get stuck: the web installer can put M-VAVE's firmware back, and an FM-1 that keeps crashing starts in a safe mode.

The design is in docs/superpowers/specs/2026-10-15-xy1-design.md.

Your projects and presets can be backed up to a computer and put back (the site's Backup page); your own samples load from their WAV files with tools/loom_samples.py (see the manual).

Building and testing

LOOM-8 is an app (app/) on fm1-base, a git submodule (base/): clone with --recursive. See BUILDING.md. tests/run_tests.sh runs everything on the host, silently (the audio goes to WAV files). LICENSING.md says where the code comes from.

LOOM-8's way of working owes a great deal to teenage engineering's OP-XY; LOOM-8 is not affiliated with teenage engineering.
