Create professional drum patterns in three simple steps — no music theory required.
Click cells in the grid to place drum hits — or hit Randomize to generate a pattern instantly. Each row is a different instrument: kick, snare, hi-hat, open hi-hat, clap, and perc.
Drag the tempo slider to set your BPM, then hit Play to hear your beat loop in real time using your browser's Web Audio API — no plugins, no installs.
Export your pattern as a .mid file and drag it directly into any DAW — FL Studio, Ableton Live, Logic Pro, GarageBand, Reaper, or any software that accepts MIDI.
A drum beat generator is a tool that lets you create drum patterns by placing hits on a visual grid called a step sequencer. Each row represents a different drum sound — kick, snare, hi-hat, clap — and each column represents a point in time, typically 16 steps for one bar of music at a 4/4 time signature.
By clicking cells in the grid, you build a rhythm that loops continuously. Browser-based generators like this one use the Web Audio API to synthesize sounds in real time, so you hear your pattern immediately without installing any software.
The MIDI export feature takes your pattern and encodes it as a standard MIDI file using General MIDI drum mapping (Kick = note 36, Snare = note 38, Hi-Hat = note 42). This makes it compatible with virtually every drum plugin and DAW out of the box.
Not sure where to start? Here are five essential drum patterns used in popular genres. Use these as starting points and customize them to make your own beats. Step numbers correspond to the 16-step grid (1 = first 16th note of the bar).

The sound effect for Mahito’s Domain Expansion in the 2021 Jujutsu Kaisen anime is a landmark in anime audio engineering.
