![]() This will cause problems with Logic in certain cases. You need more than 5GB RAM to take advantage of this feature of the new EXS-24, and you have to turn on Virtual Memory in its option screen (see the linked article).ĭoesn't this just make you want to rock out?Īs you have discovered, OS X (for the most part) is a "leave it alone" OS.ĭo not turn off Spotlight. "Internal audio resolution: 32-bit floating point 64-bit precision where required"Īnd right again on the EXS-24 (which I didn't know about - thanks Spectacle!): 64-bit numbers just take up two storage locations. without spawning a separate 64-bit process). The latter can be done within a 32-bit address space process (eg. This is potentially confusing, since 64-bit address space (which allows for access to more than 4GB RAM) is different from 64-bit precision computing. This means an app would need to spawn a separate process for 64-bit address space. Namely, the 64-bit process can only use libSystem. Your advice is much appreciated!Ħ4-bit addressing is supported in Tiger with certain restrictions. Thank you all for the suggestions and the warm welcomes. Again, If I am misinformed on this issue, please do let me know. When I finally do move to Leopard (which will be a while), then I will probably go for more RAM. I certainly do not seem to be having any RAM problems at the moment, as the Activity monitor doesn't show a huge spike in RAM usage. So I figure that as long as I'm not using any huge sample libraries, then 3GB should suffice for the time being. I am fairly certain that Tiger is only a 32bit OS, so that would mean I can only address 4GB of physical RAM until I move to a 64bit OS, which I think Leopard is. I may be wrong on all of what I'm about to say, so please let me know if I am misinformed. Well I have 3GB RAM, and here is my hesitation on maxing out RAM right now. And it would make way more difference than most of the tweaks mentioned here (though do them, too). ![]() allowing the drives to spin down should extend their life).Īlso, third-party RAM is absurdly cheap now.įor peanuts, literally, you could double your performance in both areas. I wouldn't recommend keeping all these changes for daily use (eg. These are things that matter more either when there's an audience or other musicians, and there's no room for glitches. If you want to get really geeky, here's a detailed list of performance tweaks.Īll that said, I haven't done any of those yet with my MPB in my home studio. If the drive with the audio files on it goes to sleep, you'll get a nasty delay as it spins up again. Uncheck "Put the hard disk(s) to sleep when possible" setting in System Preferences->Energy Saver.The stock 5400 RPM internal drive on the MPB is ok for a laptop, but if you're doing lots of simultaneous tracks, the faster the better. Drag your drives' icons onto that list view. ![]() Go to System Preferences->Spotlight and click privacy. Some of these can churn on the drive for quite a while.
