Weft Loom

A free, open-source desktop app for making music with Strudel. Every pattern of a song is shown twice: as controls and as Strudel code. The code is the song; the controls read it and rewrite it, so you can make a whole song without writing any, and read or change the code whenever you want to.

• Step grids for drums, piano rolls for notes, and a knob for every number in the code.
• A browser for trying and choosing sounds, and for recording or bringing in your own.
• A Song panel where you choose the bars each pattern plays in, draw a knob over the song bar by bar, and give a pattern versions for the verse and the chorus.
• Scenes for playing a song live, and notes played in from the computer's keyboard.
• A mixer with volume, pan, tone, a limiter and level meters.
• Export as a sound file, as a file for each pattern, as code, or as one .weft file that holds the song and its sounds.
• Jams: two people on one song at once, each on their own machine, with chat, voice and a camera.
• Publishing songs to the site, where others can listen and open a copy.

How each of these works is in the docs, with pictures.

Run it

npm install
npm run dev          # in a browser, http://localhost:5180
npm run tauri:dev    # in a desktop window (needs Rust)

The dev server also starts the relay that jams go through and the site that songs are published to, both on this machine.

Test it

npm test             # unit tests
npm run test:e2e     # browser tests, in WebKit (what the macOS window uses)
npm run typecheck

The site and the relay

npm run build:server

puts the site and the relay into dist-server as one file that runs with Node alone. server/start.ts says what it reads from the environment.
