Hi! How would you synchronize bpm, pitch and playhead position on 10-20 different devices*, all on the same closed ethernet network? *Mac, iPad and iPhone. A single device is master. Required latency tolerance in sub millisecond range, ideally sample sync. All the devices will play up to 64 channels of audio each. 48khz 24bit wav. I have considered two strategies: Broadcast all user events from master and replicate them on the slaves. Broadcast a continuous stream from master, comparing it on the slaves and slightly increasing / decreasing the corresponding parameter. I have the feeling there are some better options out there as these are neither fail safe nor very accurate. I have looked into the Ableton Link SDK, but it does not support position sync (only beat sync). All the best.
