Getting started

  1. Open orDrumbox in your browser — no installation is required.
  2. Pick a drum kit from the available acoustic, vintage, electronic, or 8-bit sets.
  3. Either start with the pattern generator or build your own pattern in the step sequencer.
  4. Adjust per-track loop lengths, swing, and per-note pitch, volume, and panning.
  5. Use the synth to design custom sounds if you want to go beyond sample playback.
  6. Save, export, or share your pattern when you're done.

Because orDrumbox runs entirely in the browser, you can use it on different devices without installing anything. The site describes it as running everywhere, so it's a practical option when you want to capture a rhythmic idea on the fly.
