Best way to audio-/midi-connect MacBook with a PC

I have some favorite plugs on my “old” PC. There was this VSt Rack or something some years ago to host plugins. Is this still available?

Or any other new fancy things?

Vienna Ensemble Pro.

Second that. There’s nothing better than Vienna Ensemble Pro for a master-slave(s) configuration, regardless of OS. PC’s and macs work beautifully together over VEP.
