Has anyone else had this problem? If so, I'd be very keen to hear from you (especially if you know how to fix it!):

- I have a patch that I've been working on using Max 5 on my old G5 PPC. I'm making use of the Max ~poly object. It works fine with up to 40+ voices. But when I move the patch to my Intel, the audio stutters erratically, and there are spikes in the audio CPU usage which seem to be at random moments, unrelated to anything obvious going on in the patch (e.g. a new sound starting). It looks as though the stutters are related to these spikes.

I've tried the system with the built-in soundcard and my Motu Ultralight and the problem occurs with both. I've checked that the built-in soundcard setup is identical on the two machines.

I tried updating to the Max 5.0.3 Runtime version but that doesn't help.

If I just put a simple cycle~ in the patch and have the poly~ present, there are stutters as soon as the poly~ has been activated.

This works! Do you know why? (I actually need airport to receive data from another computer, although I could attach a wire...)

A bug in the Airport code crept in a couple of revisions back.

Supposedly fixed with OS X 10.5.4.

There was a system update a while back, 10.4.X, that introduced the airport issue...not sure when it's going to get fixed...meanwhile, you'll have to link up another way if you want to maintain audio integrity. Try searching the archives for more info, I seem to recall there might have been some sort of workaround posted here a while ago.

this "workaround" consisted in downgrading the Airport software ...

I could be wrong, but i don't think the Airport

Extreme update was part of any 10.4.x update, but was

I have several machines running 10.4.11 and they still

pester me with reminders for the Airport update now

Extreme update was part of any 10.4.x update, but was
introduced in 10.5.

and again, which I ignore, of course,

i think it started with the 10.4.11 update - I still remember the 

intuition i got to say "turn airport off" to one of my friends who

i think it started with the 10.4.11 update - I still remember the

suddenly had many many cliks

How odd that Airport should be doing that.

Thanks so much to everyone who replied - that fixed it in a jiffy. You've just saved me an all-nighter, trying to move a project onto my old machine. :=)

Thanks for the heads up on this. Great thread!, completely irrational, enigmatic bug averted (or at least solved within 5 minutes).
