i've recently had four shows disturbed by audio glitches, and I can't seem to fix it whatsoever.
I effected a great performance improvement on both my MacBook Pro and my dell laptop by ensuring that I disabled all internet connectivity prior to looping.
On a related note, I have found that some FW drivers create latency log jams when running certain audio cards on the FW buss. For instance, the Texas Instruments FW driver that automatically loads in Windows creates conflicts with FocusRite and MOTU firewire sound cards-- removing it and installing the windows generic driver greatly improved performance of abletone and mobius under windows. Similar conflicts may exist under the hood in Mac OS X.
For windows, there are latency checking tools that can help you find conflicts.
I do not know of a similar tool for Mac OS X, unfortunately-- if some one knows of one, please advise.
Still, some of what I learned from this tool under windows resulted in performance improvements when I applied similar tricks to my mac. In particular, wireless internet connectivity seemed to be a source of streaming conflicts on the Mac Book. On a related note, when I went from 4 GB of ram to 8 GB on the Mac book, all performance problems went away regardless of machine configuration. Cheers Daniel

Mr. Matthews,
I can't speak for Zoe, but I have to tell you, i've recently had four shows disturbed by audio glitches, and I can't seem to fix it whatsoever. I wish I knew how to go into the console and find the errors so I could yell at Apple more effectively. This i the first computer, and it's new, that I've EVER had this problem and it is seriously messing with my scene. I think we need to talk further about this. I'm about to go a little bit bonky with this serious liability in my performance scenarios. Thanks for bringing this up once again. I'm beginning to think it's indeed in my mac, after having isolated everything else.
Bests,

Ableton has great integrated tutorials. I still as of today can't do looping and effects with a Macbook Pro i7, Fireface UC on OSX. I have to boot the machine into Win7 that is tweaked out to not have random loud audio glitches. I've been troubleshooting the thing for a year awaiting the day I don't have to use Bootcamp. (Yes this is at 128 sample buffer) Every time an audio glitch happens(sounds like a synthy/bit reduction type sound for a few seconds) I can go into Console and see the message where there was a buffer underun.
Although this is just my experience..... as Mr. Reynolds and Zoe both use Macbook pros with Ableton and it seems like they tour with it no prob. Maybe its the dual i7 cpu in the 2010 MBP? Who knows. I'd love to a glitch free system going in OSX. I never use over 20 percent of the cpu. Tim Exile has talked in forums about his trouble using a 2010 mbp for live use. He was able to fix it by disabling hyperthreading and 1 cpu! I tired it but that solution didnt work for me.
Maybe the new 4 core i7 MBP's dont have the core audio glitches?
My vote is if your good with computers is to build a windows box. That way if you run into issues you have much more control over the OS and don't have to sit around and wait, hoping that Apple will fix your issue.

I have a macbook 13" 2 GHz Intel Core 2 Duo, but I'd be willing to get a macbook pro, or even build a windows box.
So, my question: should I start learning ableton? Ableton has a looper, but should I use Mobius inside Ableton? I want to be able to have an arrangement, but also trigger different clips (improvised section), but also record loops with bass, guitar, aux percussion, and incorporate those too.
Thank you looping community, Adam
