Would be very interested to hear from anyone experiencing similar.Īnyway, if anyone has anything to add before I nuke this install, I'd be eternally grateful. Much of the glitching and fizzing happens as a matter of course during playback, but I've noticed that sometimes a session that is otherwise working fine will start to crap out if I quickly scroll through the tracks, or sometimes even open a plugin GUI. Forcing it to only use the discrete card has no effect, and - predictably - forcing it to use the onboard graphics results in severely degraded performance. Using the GFXCardStatus app, I've noticed that running Pro Tools makes Lion switch to using the discrete graphics card rather than the Intel onboard graphics. This model of Macbook Pro has the 'issue' (although Apple claim it is normal behaviour) of the battery not charging under 'heavy GPU load'. Tried Mbox 3 mini, Mbox 2, MOTU 828 MkI, built in audio. Made sure no apps are running in the background. Turned off all networking - wi-fi, Ethernet (and deleted Firewire networking as per the troubleshooting docs). Used JCDeshaies app to clear the preferences No effect (although naturally, lower buffer settings and CPU resulted in further degraded performance). Tried every combination of buffer / processors / cpu usage / plug-in buffer / host engine settings / delay compensation. Once I got to around 35% CPU usage, it started to crap out.ĭid a clean uninstall of Pro Tools 10, and reinstalled the app and the 10.1.2 update.

I opened a session, and started adding Avid plugs (Channel strip and D-Verb).

I removed all third party plugins to see if that was a problem. Macbook Pro 17' 2.2ghz quad core i7 (8,3)Īudio drive - Lacie Quadra Firewire 800 (I've tried using sessions on other drives and even on the system drive - but the problem persists). If I tick 'Ignore errors during playback', it will play - but with intermittent glitching and fizzing, accompanied by visible CPU spikes in the system usage window. I'm hoping someone else has had a similar experience and can offer some suggestions.Īny session, once the CPU gets past around 35%, will constantly give -6101 or -9128 errors. The one thing I haven't tried yet is the nuclear option - system wipe and fresh install of Lion. Not cool!Ĭan I preface all of this by saying that I've followed all of the troubleshooting guidelines. OK, I'm having huge problems with performance on my Macbook Pro and Pro Tools 10.1.2 - to the point of it being an embarrassment in front of clients.
