Sorry can't find any info on Emagic Sites - my sytem is a Dual 2Ghz G5. Thanks

However, for effects plugins you have to do a trick to get them to be thrown onto the second processor. I think it's something like insert an I/O, make sure it has an Input and Output set (not just the default "---", then disable it. This causes the plugins (and maybe virtual instruments?) on that track to be thrown to the second processor.

Then you should see a dual cpu meter if you click "System Performance" in the Audio Menu. "Audio" means cpu in the window that opens. Best Ray ------- Raymund Beyer http://www.brainstorm-music.com

The above info only apples to OS 9.x.x If you're on a G5 then that means you must be working in OSX so none of the above apply AFAIK. CPU load distribution is handled by the OS in X so Logic works as good or bad as any other program in the same OS. -- ==/==/==/==/==/==/==/==/= Paul Najar Jaminajar Music Production http://www.jaminajar.com.au

I was getting the wrong impression from Logic's Audio CPU load meters, which rarely stay balanced. Looking at it more closely, it appears that it does put different instruments, etc, on the two "CPUs", though it almost looks like the assignment is done once and then as different combinations play, the load becomes unbalanced. BUT, watching the Apple CPU meter indicates that things are very evenly balanced. So either Logic's meters are misleading, or maybe MacOS X is throwing other tasks (screen updates, etc) onto the processor that Logic has least loaded, balancing things out in the end.

Sorry Paul this is not quite right: the early 6.x versions handled those both cpu's similar to OS 9. The load of course was swapped over both of them, but you couldn't get the same out of the cpu that OS 9 gave with the I/O plug-in trick. AFAIR v6.1 of LPX Logic changed it's behaviour (it was in the release notes as well), making full use of both cpu's under certain circumstances (sometimes requiring to select an AI in the AR). Since this version the performance of Logic is similar to what we got in OS 9 will all the tricks (I/O, Rewire). For some reason many users didn't notice this change, even if it gave about 30-80% more available power depending on what you do, compared to the previous versions. Further, the G5 can balance the load between the the cpu's much better than the G4's, that's one reason why they are even more performant compared to clock speed.

Thanks for the clarification Ray. I've not yet enlisted OS X for primetime here although I'm starting to experiment in it.... -- ==/==/==/==/==/==/==/==/= Paul Najar Jaminajar Music Production http://www.jaminajar.com.au

Thanks in advance. Concerning the I/O helper in OS X, it does not seem to be able to do load balancing anymore, may be I do not set it properly ? I made a trial to move the Inputs to the second CPU did not work I think I also did a trial with an EXS24 instrument too a few weeks ago, same result ! Best regards Cyril Blanc France
