  • CPU overload problems!

    I have a G5 1.8 iMac with 768RAM and am using Logic Express and Garageband. With both I cannot get more than 4 or 5 tracks at a time without it saying CPU overload. I have tried optimizing CPU and locking tracks but it still won't work.

    I don't understand its not like I want 64 tracks, Id be happy with 8. I had 3 tracks with loops, 1 with guitar through a Presonus Inspire and Guitar ig plugin and one with midi controller playing software instrument.

    Is there a less powerhungry recording application?

    Should I invest in more RAM or external hard drive ?

    You should get a load more than that. I have played reasonably extensively with both GB and Logic Express on a G5 1.6 gig iMac and it's capable of way more than that. The iMac G5's have 7200rpm drives internally as well so although an external is a much better option, it shouldn't be that cripple..

    Other people here could help.

      Wel I was adivised to unplug my Firewire interface (Presonus Inspire) and it seems to have worked fine meaning I could play a song in both Logic and GB simlataneosly without a problem.

      My challenge now is to get my Firewire interface working properly wihtout draining my system. I was advised to downgrade to 10.4.2 from 10.4.3 but Im not sure how I do that and if that is the best option.

      Any help would be appreciated.

        Are you using Logic and GB at the same time?

        If so, how come?

          No. I only did that to make a point when I tested my computer without the Inspire. I was curious to see how much it could take but usallu I only run one at a time.

            What are your buffer settings with the audio interface?

              It's a bug that exists with many firewire audio interfaces (ex: Presonus Firebox, Ediro FA 101, etc.).

              In fact, there is a problem with the Apple FireWire Audio driver, built into MacOSX, that manages all these "Class Compliant" Firewire interfaces.

              Let's hope it will be resolved with Leopard.

                Start with much more RAM - load the machine with as much RAM as you can afford. Still, you should be getting better track counts than that.
