This seems interesting. :)
"Separated server solution that doesn’t address RAM used either by your host sequencer or by Vienna Instruments plug-ins running alongside the sequencer and Vienna Ensemble."
"Prepared for 64-bit PCs and Macs"
I wonder if these mean in Vista 64 that the application is 32 bit but it has its own address space meaning that if the DAW addresses 4 gigs the Vienna Ensemble can address another 4 gigs?
