This works for a listener down the chain, but obviously can't work for performers playing together. The article mentions a producer listening to remotely located performers as they were playing together, but fails to mention how these remotely located performers can sync to each other in the first place.
Explained in the article:
> A producer sends a backing track to a performer - SyncDNA adds a slight delay to the outbound feed
The "backing track" is probably the beat or something similar.
I still fail to understand why this is a thing. Two possibilities:
1) the beat is created live by a human performer who can't meaningfully hear the other performer(s) in time. He / she is stuck with playing blindly.
2) the beat is pre-recorded - sampled or electronically generated on a sequencer. Then what's the use case in the first place? The other performer can download it offline and play on it live.
All this is done to get something that mimics a live performance (but isn't, because the band components can't hear each other in real time) to someone listen-only at the end of the chain. What's the advantage in doing so? What's the use case?
