Drum Beast

Click a cell in the step grid to activate it, string together a pattern across eight or sixteen steps, then hit play and hear your beat loop back immediately. Drum Beast is a browser-based drum machine and beat sequencer — no plugins, no installs. You get a classic row-per-instrument layout where kick, snare, hi-hat, and a handful of other voices each get their own track to program independently.

Once a groove feels right, you can record the pattern and export it as a JSON file, which makes it easy to save your work or tinker with the raw data later. It's a focused tool: nothing excessive, just the controls you need to sketch a beat quickly. If you want to go further into generative territory, Orca goes in a completely different direction, building rhythms through a live-coding alphabet grid.

Drum Beast works best on a desktop browser, since the full step grid spreads across the screen and clicking individual cells with a mouse is considerably faster than tapping on a phone.
