I just put together a network of 3 PCs running 64bit Vista. My host is 64 bit Cubase 5. For Orchestra mock-up, I'm using Vienna Ensemble. For non-Vienna VSTs I'm experimenting with V-stack with an RME audio card and FxTeleport.
V-stack is working somewhat, but has some serious bugs with regard to maping VST outputs. FxTeleport would be ideal, but is really unreliable. Some VSTs work and others don't; and sometimes a VST works until used with another VST or until re-loaded.
I have the ability to dual-boot into 32-bit XP Pro and find that the same issues exist under XP Pro; plus some more issues related to having less memory available.
I'd appreciate any suggestions for an alternative to FxTeleport.
