In their own words
mpump
mpump is a browser drum machine, groovebox, and step sequencer for creating beats and sharing them as links. Someone opening a shared 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, as well as 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 imported or exported as JSON. The PWA works offline after its first load. Live Jam supports up to 4 peers, and Live Set supports up to 49 listeners; both are opt-in and currently need a user-provided relay because the public hosted relay is offline. The maker says there are no accounts or personal tracking and music stays on the user's device. mpump is free on Android, iOS, and the web, with source code under AGPL-3.0.
XO
XO is a drum sample organizer and instrument for macOS and Windows. It arranges samples by sonic similarity so users can audition sounds and rhythms rather than search folder by folder. The library includes more than 8,700 one-shot samples and more than 240 editable beat presets. XO sorts samples regardless of their storage location or format, including duplicates and files on external drives, and provides filters and search. For creating patterns, it includes Groove Templates, pattern nudging, and an Accentuator for adjusting feel and dynamics. Users can drag and drop samples, kits, stems, or complete beats as audio or MIDI, raw or processed. XO supports VST, VST3, AU, and AAX hosts, including Ableton Live, Logic Pro, Pro Tools, FL Studio, Reason, Reaper, and Cubase; a standalone app is also available. It supports MIDI, sample import, live performance tools, and eight pattern tracks. XLN Audio offers a 10-day full-feature trial without payment details. XO costs £76.20, paid once; XO + 4 expansions costs £95.40, paid once, and XO Complete costs £399.50, paid once.
