Composable hooks for score loading, MIDI playback, note highlighting, auto-scrolling, and piano sampling. Consumes pre-rendered static assets — no client-side MXL parsing.

MXL files must be pre-rendered to static SVG + MIDI via Verovio WASM on Node.js. The browser only consumes these static artifacts — zero runtime rendering cost.

Use the muse-render CLI to batch-convert MXL files into ready-to-serve directories with SVG pages, MIDI data, and manifests.

Built-in piano sample loading with compressor and reverb effects chain via Tone.js. Covers 84 notes from C1 to B7.

Colored overlay rectangles highlight actively playing notes on the score — blue for right hand, red for left hand.

Five focused packages — core, component, server, cli, and instruments — each independently installable with clear responsibilities.
