Ok, so also the OS and app has to be 64-bit to gain access to larger amounts of RAM? This is a bit confusing with all the different answers. Does someone have a solid knowledge on this matter?
OS has to be 64-bit capable. Both OSX 10.5 and 10.6, running either 64 or 32-bit kernels, will be able to load more than 4GB in VI. Your sequencer can be running in either 32-bit or 64-bit mode - VI will still be able to address more than 4GB of RAM.
As an example, by running any Cubase, Logic or DP on OSX 10.5 with an Intel Mac, you will be able to address more than 4GB in the new VI.
