BeatCircuit per AnhTan_Dev

BeatCircuit is a compact music sequencer and synthesizer built for the Firefox popup. Program kick, snare, hi-hat, and bass patterns across 16 steps, switch between four scenes, adjust tempo and sound controls, and edit probability, velocity, and pitch per step. Generate Euclidean rhythms, lock individual tracks, mutate patterns, or enable Evolve mode for gradual automatic variation. Sounds are generated locally with the Web Audio API and no remote audio files are loaded. Patterns and settings are stored locally in Firefox.
