From Software Updade: Logic Pro 7.2.2 improves compatibility with the mac pro and delivers: Increased performance through full use of the Mac Pro Quad-core architecture Optimized support for the built-in audio ports Logic Pro 7.2.2 is recommended for all Mac Pro users. An existing Logic Pro 7.2.1 installation is required for this update. Note: Use of Logic Pro 7.2.2 with the Logic Node application requires an update of the Node software on your Node machines. The Logic Pro 7.2.2 Update places the updated Node application in the Applications/Utilities folder. Please copy this file to the Node machines and run it. It SCREAMS on my standard configuration Mac Pro. Does anyone have any benchmark Logic projects that they would like me to try?
