*Or with a bar or two delay
I've seen it work. Bass player in Madrid, Singer in Berlin, Guitarist someplace else. All jamming, real time, sans-latency.
When latency become an issue, you can still sync over midi, with a bar or two delay. I've seen musicians go for hours on end and believe the audience will follow!
Imagine the latter being able to control camera/lights over midi.
Add in streaming sats.
Need crew to integrate 4+ pieces of FOSS into a coherent whole!
