Weft

Weave songs from patterns.

Weft is a free desktop app for pattern music, built on Strudel. Click drums into a grid, draw notes in a piano roll, turn a knob, and the code follows. Change the code, and the controls follow. Play alone, or jam on one song with someone else.

Free. No account needed to make music.
