summary

An Ember app ties roughly 40 phones together over socket.io and the Web Audio API, schedules sound by syncing device clocks, and assigns twelve orchestral parts so each phone plays a slice of Beethoven; a Node server and Ableton Live bridge add four controllable synth parts. Latency measurements show most devices under ~50 ms but some outliers; a race condition makes the server crash in rehearsal, and live demos partly succeed and partly reveal platform audio fragmentation.
