What Groovie is

Groovie is a free, open-source drum and beat sequencer that runs in a browser on desktop computers, tablets, and phones. It includes more than 150 public-domain CC0 samples, covering drums, percussion, vocals, game sounds, and other sounds. A pattern can contain 1 to 64 steps and up to 16 rows, with up to 64 patterns in a project. Each row has controls for its sample, panning, level, and delay send; Groovie also provides tempo-synced delay and a filter for the full mix. Tempo ranges from 40 to 280 BPM, with swing and humanize controls. No account or installation is needed to use the browser app. A shared link carries the project in its URL hash, so others can play or remix it without the project being uploaded. Groovie can send MIDI start, stop, and clock signals to connected devices, though MIDI clock output is limited to Chrome and other Chromium browsers unless Firefox has an add-on. The maker describes it as a tool for teaching rhythm and music production and sketching ideas.
