i'm running a dual 867 with no probs and pretty good track count. the only problem that i have is that i can't use multi's because it isn't enabled on logic 6 platinum. oh, and i am using logic. maybe it's nuendo.(please don't take this as a stab at nuendo) hopefully not. one other thing is that i'm on 10.3.6. this "may" help. not sure. i hope things work out for you soon.
i read somewhere that it was disabled.. i think it was in the update info.... if this is not true then i'm a really happy man!! i tried to do it anyways even after reading the info and i couldn't make it happen. maybe i'm doing something wrong. i will read the pdf and see what i can make of it. can i keep you informed on how it goes? thanks.
