Lightning Talk: Elixir, MIDI and LiveView
summary
Filesystem watcher detects code edits and eval_file hot reload reevaluates music code at runtime. A GenServer preserves state across reloads so playback position and sequence survive code changes. MIDI messages are emitted to external or virtual instruments — demo routes notes to a virtual synth and shows live audio output. LiveView renders SVG-based notation and a broadcast channel syncs player events to the browser. The demo runs live and successfully adds variations on the fly.
