It doesn’t appear to work here for me sadly.
I open up Cubase Pro 8 (latest build), fire up the trial and all seems ok.
I type in a name (Engineer as suggested), click the button to get a number.
I open my iPad to test the sync between the PC and iPad and type in the number from my PC and into ‘VST Connect Performer’ but receive a couple of messages:
1 - unconnected
2 - unable to use same connection
Hmmmm - obviously, user error, but I don’t see how to fix this.
