Could it be that emapple want us to be fully native and buy G5s rather than interfacing with 3rd party soft/hardware like UAD and Powercore and their attendant plug ins ie Sony Oxford? I can see no other why such a fundamental flaw in Logic's architecture is allowed to exist, while Steinberg and MOTU have already implemented PI delay compensation. MOTU even mention UAD and P/Core on their web-dite front and centre. Sure we can survive and adapt as we will but it is a very poor weakness in an otherwise stellar programme. Cheers Clive Young
