A browser-based salsa sequencer for studying how nine instruments lock together across the 8-beat clave cycle. Two independent implementations built from the same brief — choose either from the landing page.
- 16-step pattern editor (eighth-note resolution across two bars of 4/4)
- Nine synthesized tracks: clave, cáscara, campana, bongo, conga, bass, piano montuno, horns, coro
- Anticipated bass tumbao and piano guajeo over Dm ↔ G7
- Stem upload per track — demo synth mutes when a real audio file loads
- Swing knob, master volume, solo/mute per track
- Web Audio API, vanilla HTML/CSS/JS, zero dependencies
