Hi, Im' being annoyed with the memory limit of WinXP pro. Many bugs occur when I try and load patches or plugins as a large cubase session in open. The same patches or plugins load fine with an empty session. In the task manager, it is said tha cubase uses 1 150 000 ko I have 4Go of physical memory. Questions: - How to check that the /3GB of the boot.ini is actually effective? - I heard that cubase SX 1 is LargeAddress Aware (LAA) - I read that if the host (cubase) is LAA, there is no need for its plugins to be patched with Laatido. Is this true? - Is Kontakt 3 LAA? I woudl'nt mind going to a 64bit OS, but instinctively, I think that Vista is not the major 64bit OS that will last a bit. I do this compared, for instance to Win98SE or WindowsXP SP1/2 wich were the ones which many musician worked with during many years. Huey
