orDrumbox

orDrumbox runs entirely in the browser with no installation, plugins or registration required, and works on Windows, macOS, Linux, Chromebooks, tablets and modern mobile devices. It offers a multi-track step sequencer with independent loop lengths per track, Euclidean rhythm generation, swing and groove adjustment, per-note pitch, volume and stereo panning, and trigger and repeat controls. An intelligent pattern generator can create complete drum patterns, regenerate a single track while keeping the rest of the groove, and automatically create matching bass lines. The built-in software synthesizer includes three oscillators, ADSR envelopes, resonant filters and LFO modulation. Multiple ready-to-use drum kits are included (acoustic, vintage drum machines, electronic, 8-bit/retro), and users can import their own samples. Projects can be saved locally and reloaded, and music can be exported as high-quality WAV files or MIDI for Ableton Live, FL Studio, Cubase, Reaper, Logic Pro and other DAWs. Live performance is supported via computer keyboard or General MIDI controllers, using a low-latency Web Audio engine. The project is open source under GPL v3, with a GitHub repository at github.com/cadeli/ordrumbox-v2, and community contributions are welcome.
