Logic Pro multi core don't work.

Hello! The problem is that in Logic Pro is one of the six core. The sound starts to croak at 1024 samples. Five tracks with the Kontakt 5. What to do? x99-a intel i7 5820k.

Did you figure out anything? That's LP9 you're using, right? If you're on OS X 10, maybe it works with LPX? Since 10.0.7 it's supposed to support 12 cores = 24 threads. I'm about to do a 2011-3 dual CPU build with 2x6 cores for use with LPX. If you can't get a single 6-core CPU to work, maybe I should rethink that!
