Show HN: Mpump – browser groovebox where grooves are shareable links

I built a groovebox for making loops: techno, house, acid, anything electronic that works in loops.

No install, no account.

The idea is simple: a groove is a URL. The full pattern, tempo, and sounds live in the link. You open it, hear it, change it, send it back different. Has drums, bass, synth, Euclidean rhythms, live jam sessions.

Would love feedback, especially from people who make this kind of music.
