Create Drum Patterns Online — Free Beat Maker
BEAT LAB is a browser-based drum pattern generator built for producers. Pick a genre preset — trap, jersey club, UK drill, dancehall, or house — and each click generates a different variation with genre-authentic BPM and swing. Build your own patterns from scratch using the 16-step sequencer.
All sounds are synthesized in real-time using the Web Audio API. No samples to load, no plugins to install. Dial in your BPM, add swing, tweak velocity variation, upload your own sounds, and export your pattern as a standard MIDI file to drop straight into your DAW.
