- For
- Pattern-music makers who want visual controls and code
- Worth noticing
- A .weft file holds the song, its code, and its sounds; the project is licensed AGPL-3.0-or-later.
Field notes
The song is represented through a timeline, grids or piano-roll notes, knobs, and code; edits in either direction update the other. Users can add audio files or record from a microphone, then cut recordings into sections or place a full take along the song. The site says two people can work on one song by invite or through a list of people open to jamming; published songs can be previewed and downloaded.
