If Alsihad sounded any better than Nuendo, I would not be as nasty about it.
It simply doesn’t… Ask our freelancer colleagues who work on many systems, what they say about it.
Hi DG
Error… Those plugs that don’t work, have mostly been discontinnued and/or can’t work in Win7 or in 64bit environment ( see Wizoo W5 ) . All supported Plugs work without problems. It seems, everytime we enter a new OS or processor technology there is something we have to leave behind (like those 3 Parhelias on the shelf, here… 
).
In my case, no disfunctional plugin problem is Nuendo 5.5 related…
