Drum Sequencer
Build drum patterns on a 16-step grid with synthesized kick, snare and hats, BPM control and presets.
16th-note grid, sounds synthesized live with WebAudio (no samples). Patterns are not saved — hit a preset or export by screenshot. Works even while playing: edits take effect on the next loop.
