Summary

mpump is a free browser drum machine, groovebox and step sequencer for making beats and sharing them as links. Someone opening a link can change the groove and send a revised version. The browser tool includes drums, bass, synth, a mixer and effects with real-time synthesis, along with patterns, arpeggiators and Euclidean rhythms. It supports MIDI clock synchronization and an Ableton Link bridge for use with Ableton Live, Logic Pro, Bitwig, Traktor, djay and other Link-enabled apps. Recordings can be saved as WAV, and sessions can be exported or imported as JSON. The PWA works offline after its first load. Live Jam allows up to 4 peers and Live Set up to 49 listeners, but both are opt-in and currently require users to provide their own relay because the public hosted relay is offline. The maker says mpump has no accounts or personal tracking and music stays on the user's device. It is available on Android, iOS and the web, with source code published under AGPL-3.0.

Who it is for

mpump suits people who want to create sequenced beats in a browser and share editable grooves by link. It may also suit musicians using MIDI clock or Ableton Link, provided they can supply a relay for live collaboration.
