The Atmosphere manual says that up to 8 instances of Spectrasonics 
plugins need 100Mb of extra memory in the host program. So, you're 
probably okay there, but could experiment with maybe another 50-100 
Mb for Logic before you launch it. Do you have virtual memory 
switched on in EXS24? (I can't remember when that became a part of 
EXS24. )

For me, the answer would be to get some more RAM. I believe that in 
these days of software samplers and synths, at least 1Gb is a 
minimum, and more is better. Obviously you can get by on less, but 
it's like cramming to many passengers into a small car!

Basically, I don't believe you're doing anything wrong......just 
drive carefully.  :-)
