How to reduce CPU usage when working in Logic Pro and Kontakt5

This might help, even though it's for Logic 8.

Also, when finished recording select an external MIDI Track or an audio track with NO input selected.

And, set all unused audio tracks to No Input.

Active Inputs use CPU.

What's really dumb is that the 'one core curse' is still alive and kicking.

Point is that when your composing have a software instrument live is EXACTLY what needs to happen. Its what Logic is there for.

It didnt used to be that way 10 years ago. Logic 6 on my Blue G3 was super efficient

Rant over

Heh, In my back room I have Logic 5.5 on a 2GZ Win/XP PC with an Athlon processor and RME audio hardware, it's legacy system I keep for backwards compatibility but Logic rocks on it.

So Center of Pan,

If you were to run something like Omnipshere on an active SI track do you get anywhere near the "1 core CPU" spike I'm getting on my Late 2011 TOTR MBP?

I still dont really get why L9 on a new MBP peforms worse than eg your PC.

Older versions of Logic (ie: 5.5) don't see individual cores, there is one disk meter and one CPU meter. In some ways it's a more efficient system. This is running on WinXP which happens to be a very good system for audio. Consider this, XP can be installed and take up only half a gig of disk space and do 90% of what most operating systems can do today.

I do see single core spikes on my single processor quad core Mac Pro. There's no way to get around a processor intensive plugin on a single track. A channel strip is tied to a single process (core). I stopped upgrading at 10.6.8 and Logic 9.1.3, because it works. I still get the occasional single core use even with multiple plugs and tracks but I can usually break the logjam by quickly starting and stopping Logic 2 or 3 times.

I will not upgrade Mac hardware or software unless the next version of Logic is outstanding, I'm fine where I'm at for the next year or two. I enjoy recording performers more than anything else so al I really need is a good sounding, solid system.

The single core for live tracks issue is one of the biggest limitations Logic has right now. Seems like they've figured out how to work around it with Mainstage, hopefully they'll have a Logic update that addresses it sooner rather than later.
