Multiple applications is the key.

It does not.

It's also a fantasy. :)

No, and Andrea from Redmatica explained this to me definitively,  
including links to the Apple site.

Each program in Panther and tiger can access 4GB of RAM. If you look  
at Activity Monitor with Logic (including EXS) loaded up to its  
breaking point, you'll find it gets up to 3.17GB or so (that's the  
max on my machine); the remainder of the 4GB is "overhead" and  
doesn't show up in that figure, but it's being used.

You can't work at that point - about 2.5GB is a practical maximum.  
That's still pretty good, because it's two Giga or Kontakt machines  
plus Logic, and you can run other programs in the rest of the RAM. I  
was able to run a Kontakt 2 outside Logic, but unfortunately the  
processor load was too high at that point (since I had two Space  
Designers open); I'm going to do some more fooling around to see  
whether that can be made to work. Whether installing more RAM would   
solve that (I have 5GB) is another question.

In any case, this is not 64-bit memory access. That's only for  
command-line programs at this point; the GUI hasn't been adapted for  
64-bit access yet.
