Thanks for the explanation, BTW I did get wormhole to work in a fashion, the latency was not constant and it was not smooth sailing, and I stopped using it. Used it to transfer tracks from a sequencer one one PC to SAW in the Primary PC. In the end I got hold of another Yamaha i88x and use that to transfer stuff using analog, not perfect but sound quality is acceptable.
Would like to find a way to do it without going via analog though.
Dante looks interesting once the price of the hardware comes down.
Cheers.
