In their own words
DrumComputer
DrumComputer is a synthetic drum instrument that combines synthesis, modulation, sequencing, randomizers, and sample import. Its eight sound engines each layer a resonator, a wavetable or analogue oscillator, and a resynth or sampler. The 16-step sequencer includes probability, rolls, step delay, swing, humanize, pattern generation, and remixing or fills. Effects include a filter, compressor, overdrive, and room and hall send reverbs. The desktop version supports MIDI file drag and drop plus multiple audio and MIDI outputs. It runs on macOS 10.13 or later and Windows 7 or later, with 64-bit versions for Intel and Apple Silicon. The iPad version requires iPadOS 17.6 or later and supports standalone and AUv3 operation, MIDI export, Ableton Link, MIDI Learn, host automation, and preset iCloud sync. DrumComputer costs $129, paid once as a download. A demo is available, but restrictions include a timeout after 30 minutes / 30 days and disabled saving and export. A Claude Desktop extension can create sounds from text prompts and requires the full version.
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.
