Is this typical of mixing performance in PT 10

[superwack]

That seems like a fairly small session and the Avid, Waves & McDSP stuff isn't too CPU intense - not sure about the Izotope stuff.

What is your buffer set to in the playback engine? How many host processors are being used? Try upping the buffer size (the one from the drop down menu at the top) that should probably do it. If not Pro Tools often runs better on an odd number of cores - try setting that to 3 (or even 2)

Hope that helps

Using all eight cores and mixing at the highest buffer size 1024.

On the Mac, the 2626 or the Glyph? The Glyph is daisy-chained via the 2626.

It is not recommended to use all your cores. Try using one less, or two less. Odd, but that's what Avid recommends.

I have found this to be the case with all the machines I have configured. I have found the best performance on several different machines, by using HALF the amount of core's in the thread allocation setting, and setting the CPU to either 95% or 99%. You can move up one, or two cores from there, but full bore core's are gonna give you the sandpaper glove.

Thanks, Doc and ocean. I do get the feeling that my Glyph is getting ready to bite it, but I'll dial back the cores to four and see what happens. Argh... frustrating.

Theze guys are correct. Set it to 7 cores 99%.

Did as instructed. No luck.

The next try/step would be to copy the session to a fresh drive and see if the error's commence with your session buffering from the new clean drive. The other thing to try - which is kinda daunting, is to do a fresh clean, re-install with all your software, and test the system without any third party plug ins installed. Then you can narrow down who is the culprit.

Many times, re-installing suspect plugs ins, will fix the random hard to figure out problem. This could very well, simply be a fragg'y drive. If you still get hosed after copy the session to a fresh drive, I'd bet its a gonna end up as wonky plug, [needed a re-install] as there is something, somewhere going screwy on you. I wish you the best of luck with this, may the force be with you,

FWIW avid recommends daisychaining the interface off of the drive not the other way around.

I'm mixing a session with 31 tracks, five stereo busses and a stereo master. I've got anywhere from one to three plugs per channel (five is max) with limiters or comp combo on all the stereo busses. Most plugs are Avid eqs/comps and Waves, McDSP or Izotope specialty plugs. I'm crapping out on playback and attempts to bounce down to a stereo master. I've repaired disk permissions on both hard drive and audio drive, and have trashed Avid/PT preference folders, but still getting CPU overload error message. Is there something wrong here? Or, is the normal? Should I suck it up, and just start bouncing down to stereo stems to lighten the mixing load?

Any virtual soft synths up and running? That seems like a pretty hefty Mac and not all that large a session in the scheme of all things digital audio these days.

yep...which actually comes down to the physical cores...pretty much. tho i haven't tested it i always wondered how much overhead it takes to run HT and how much one gains or loses when usin' it. FWIW...on my C2Q, which doesn't have HT, i run 3cores @99%.

Try copying session to internal drive and bouncing from there.

If not, try disconnecting interface, using internal audio just for the bounce, and bounce from there.

Thanks psycho. I plan on doing that after an uninstall and fresh reinstall of PT. Quick question, I just downloaded the PT 10.1.2 Updater from Avid. When I reinstall, do I go the full Monty and uninstall the VIs, libraries and the DAW? If so, do I have to reinstall the first PT 10, then update with 10.1.2? Or, should I even bother and just update with 10.1.2? Any insight or advice would be greatly appreciated.

Some of the Izotope plugins can be very CPU heavy. (And I think all plugins with high latency). I can run hundreds of simpler plugs but can bring my DAW to it's knees with 5 instances of Ozone.
