Logic 8 / Old G5 issues?

Postby Bigga J » Tue Jan 22, 2013 9:48 pm

I'm running Logic 8 on a pre - Intel (Dual 1.8) G5 and I've been seeing more and more instances of the 'audio engine overload' message lately where everything grinds to a halt. The annoying thing is that the CPU meter shows one processor hitting the red but the other one barely flickers at all so what on earth is it doing?! Shouldn't it be sharing the load instead of freezing up everytime my tracks/plugs/automation build up a little?? Before anyone suggests I buy a new computer, please don't as that's not feasable for now - all other advice is appreciated

Even on Intel apple suggests sending tracks out to a bus to help redistribute core loads.

A 3yr old mac used mini would kick your G5's ass!

Assuming we're talking about CPU load, rather than disk I/O load:-

One single channel strip gets processed on one core, for technical reasons. So, if you have one channel strip with a heavy instrument plugin and a bunch of other heavy plugins, it's quite possible to overload that core, even though the computer has "extra power" available in the other core.

You can redistribute plugins across multiple channels in the instances that you need to do it.

Thanks Des. I'll re-jig some of my plug-in stacks and see how I get on, having said that, the disk I/O was peaking as well simaltaneously with the CPU max outs.

Thanks G but for now I'll be guarding my G5's backside and my debit card from Mac minis

Well, resource allocation is complicated so you may well also have other issues going on (streaming samples, audio disk traffic, bus throughput issues and so on).

At the end of the day, your machine only has a certain amount of power, which isn't much by today's standard, so if you are asking your machine to do more than it's capable of doing, (settings juggling aside), then you have to employ some other strategies to maximise your limited resource - flatting audio, bouncing tracks, committing instruments to audio, bouncing sub-mixes, freezing channels and so on.

G-Double, just for the record, I DID NOT go straight onto the Apple store website and start doing calculations off the back of claiming i'm broke


P.S. Thanks again Des - might be upgrade time but don't tell G-Doubleyou
