Hi Jim B. 
For me / us as Cubase Pro Users is VST Connect a great innovation. “My” drummer is not very closed to DAW science and it would be great to give him (and me for respect ) a chance to place his playing directly into my DAW.
Because my drummer is on Mac too, I can connect to his computer via Facetime and setup his hardware remotely (he’s running Studio One with Behringer UMC).
My very big question is : If my drummer installed VST Connect Performer, how could I a) record his eight outputs AND b) how do we communicate?
On Mac we have a so called “Aggregated Device” which can include any audio device into one. My hope is that I can talk to my drummer via build-in-mic or enclosed mic over my mixing desk.
But first of all … VST Connection Pro must work
