How live music is evolving in a post pandemic world
summary
Claims that browser music is practical get backed by concrete techniques: using Web MIDI & Worklets with plain WebSockets to send tiny MIDI events, batching them into relay sampling and playback chunks, and measuring offsets with performance.now to align parts. A live demo actually lets audience members play together over the page, revealing the surprise that it works reasonably well locally but degrades past 300–400 mile latency limit. Observability and regionally distributed testing turn out to be essential to diagnosing failures.
