Our verdict on mpump
mpump is a free, open-source browser groovebox for loop-based electronic music. It is designed for beat makers who want drums, bass, synth parts and effects in one interface, with access through modern browsers on desktop and mobile devices as well as dedicated iOS and Android platforms. It runs without installation or an account, and its shareable beat links make it suitable for exchanging ideas and remixing sessions.
Its sequencing and sound design coverage is wider than a basic drum machine. The step-grid editor provides per-step semitone, velocity and slide controls, while synthesized drum, bass and poly-synth engines cover multiple core parts. An arpeggiator and Euclidean rhythm generator add pattern-building options, and custom audio sample loading extends the sound palette. Real-time effects, a mixer with EQ and compression, WAV recording, and JSON session export/import give the workflow useful depth. Optional live jam and live set modes also support performance-oriented use.
The Free plan includes the browser groovebox, drums, bass, synth and effects, and shareable beat links. MIDI device connection, MIDI clock synchronization and Ableton Link support help it fit into setups that already include external hardware or compatible music software. However, live collaboration has an operational limitation: the public hosted live-jam relay is currently offline, so those features require self-hosting a relay. mpump is a strong choice for users who value open-source access, cross-platform availability and remixable sharing. Users seeking a maintained hosted live-jam service or a paid support tier should consider a different tool.
