Another thread about a Core audio system overload!

After reading through page after page and trying every little tip and fix, and still not being able to fix the problem, I am not frankly amazed that no-body has sorted out a proper fix to this problem, because in all honesty, logic is un-uesable in this state.

pleae could somebody help me as nothing is working for me!

Sam:

I understand you're frustrated, but you're giving no information which would help with your problem.

What are you doing when you get this message? What hardware, software, memory and hard disks do you have? How many tracks, software instruments, prosessors do you have running? What is your system performance window telling you?

Sure, there are users who have problems, but there are a lot more for whom Logic, Tiger, hardware etc. are running very well hour after hour, week after week on recording sessions.

Have you read through this?

Thanks for your quick response... I am fairly new to all of this, but I still more or less know whats what... first off I have read through the llogic bible of trouble shooting and tried everything suggested in there, including downloading the app support update thing.

hopefully this will help...

Hardware Overview:

Machine Name: iMac G5
Machine Model: PowerMac8,2
CPU Type: PowerPC G5 (3.0)
Number Of CPUs: 1
CPU Speed: 2 GHz
L2 Cache (per CPU): 512 KB
Memory: 1 GB
Bus Speed: 667 MHz
Boot ROM Version: 5.2.5f1

I am running tiger, and my sound card/driver is a tascam us -428.

I am running Logic pro 7.1.0 as it comes straight out of the box, but with 3 extra soft synths and a extra drum machine. I have no hardware devices.

My song has 15 instrument tracks and no audio tracks and everytime I try to play it I get this message after a few seconds of play...

Core Audio:
System Overload.
The audio engine was not able to
process all required data in time.
(-10011)

I have found that is I go into the audio preferences and turn the universal track mode off and then back on it plays alright for about 5 mins before the same thing happens again.

Thanks for your help

My song has 15 instrument tracks

have you considered that the reason why you may be getting a system overload is possibly because you may be overloading the system?

open the CPU window (the thing that shows a bar display for CPU and disk usage) and see what it says. as your song plays, it is very possible that you are hitting parts of the song where the demand on the processor becomes too high. software instruments vary a lot in their demands on the processor, and this also goes up significantly with more polyphony. for example, if you are using sculpture, you will find that it uses a lot of resources.

there are ways to manage this load. be aware of your polyphony usage - limit it within the synth/sampler editor if you can so that decaying notes don't use up extra CPU if unnecessary. also, freeze tracks if you have an intense plug in, or a synth with lots of effects on inserts. solo various instruments in your arrangement (using the solo button in the transport, not the channel strip solo) so you can individually monitor the CPU usage of each instrument. then you will know what to freeze, or at least, what instruments are chewing up the resources. also, make your i/o buffer higher, which generally will gain you some CPU overhead.

To be honest I dont think it is that, It doesnt make any difference if I change the polyphoy on any of my instruments, and I can even completle delete the track and I have the same problem, my computer is brand new and has all the lastest updates, I am sure this should not be happening,

I posted up all of the details of my setup, can anybody help please?

thanks

TBird is probably right in that it is the instruments you are using. You've listed your setup... what about a list of the instruments you are using for your song?

It doesn't matter if your computer is brand new. if you are asking too much of it, you will get overload messages.

15 audio instruments is a lot for an imac G5, especially if they are CPU-hog instruments.

the other thing you need to check is your i/o buffer setting (in audio hardware and drivers). make sure it isn't set to anything ridiculous (like 32 or 64).. put it at 128 at the very least, or 256. that should keep the latency acceptable for playing your instruments and also lower the bar somewhat on your CPU overhead. that could help.

let us know what instruments you are using and how much polyphony is going on, also what additional plug ins you have running - people here will be able to give you an idea as to whether you are pushing the limits or not. open the CPU meter and look at what it says, as I said earlier, there may be passages in your song where the demands suddenly go higher. this is when freeze tracks becomes useful.

Could be the tascam 428. I had a 122 and it would start to farrt out at 10 instruments testing on a g5 tower. I would save the song as a different name, open that up, see if that works.

Did you say if it worked with 10, 11, 12, 13 instruments or will it not work with any? Also if your running Sculpture that one will kill it for you.

good luck

Hi thanks alot for all of you help and suggestions...

As far as the vst plugins that I am using go they are the-

fxpansion guru drum machine

albino 2 synth

novation v-station synth.

I have tried altering all of the voices on all of my plugins so that they are all mono, and that has no effect, I can even delete all of my tracks and then the problem is still there. to be honest I am convinced that this is more of a techinal fault as opposed to it being a cpu issue, due to the fact that it was working fine up until a point when I saved my document, then later, when I re opened it and then the problems started...

also my i/o buffer size is currently set to the maximum... 1024

Another curious thing is when this problem first developed, around 2 weeks ago, I found a tempory type of fix, by turning the universal track mode off, and then back on I could get normal play back for about 5 mins, but now even that doesnt work, and I have not altered my document since that worked.

Finally I have tried to play back my song with the system performance window open, it has 2 meters, the audio and the disk I/O meter. When I start to play back the audio meter overloads but the disk has no reading. As I said before I am fairly new to this, and do not know what the readings on this window should look like, but im sure there should be sum I/O reading, shouldnt there?

Thanks again for all of your help

If your audio meter is of the hook in that display then it is because your iMac is to 'light'for your logic track. If you use 15 different instruments in one song then it is a little bit to much for one iMac G5. Try scaling your song down or better freeze a couple of tracks.

Thanks for the suggestion, but to be honest I still have a problem believing that, due to the fact that A: my system spec should be enough...

Machine Name: iMac G5
Machine Model: PowerMac8,2
CPU Type: PowerPC G5 (3.0)
Number Of CPUs: 1
CPU Speed: 2 GHz
L2 Cache (per CPU): 512 KB
Memory: 1 GB
Bus Speed: 667 MHz
Boot ROM Version: 5.2.5f1

with a 200 gb hard drive 120 gb free,

from what point of view could my computer be faster/ bigger, meaning what does my computer lack that would make Logic run smoothly?

And B, I use to have an g3 imac with a 40 gig hard drive running os 9 and cubase vst and 15 tracks in that was no problem! The computer I have now is about 10 ten times bigger and better, and cant cope?

I can even delete all of my tracks and then the problem is still there

That makes no sense to me either. If your soft instruments aren't playing anything, I don't see where the CPU loading is coming from unless you're talking about deleting regions and not bypassing the instruments - even without playing the instruments still take up some CPU capacity. Bypass them, and then test.

due to the fact that it was working fine up until a point when I saved my document, then later, when I re opened it and then the problems started...

AhÉ have you tried transferring/recreating your track from your existing arrangement into a brand new arrangement? Maybe you have something weird with your .lso file, or maybe a corrupted supporting file or sample?

the audio meter overloads but the disk has no reading

That's what I would expect. You'll only see the disk meter increase as your audio files increase and the disk activity increases.

When I start to play back the audio meter overloads

At what point? Same place in the song each time? Is there a particular instrument that kicks in at this point? If so, disable it/them and play back again. Once you can isolate the intrument(s), you might be able to diagnose more easily

I am convinced that this is more of a techinal fault

In view of what you've tried, I'm agreeing with you. Stick with it though, as I think you're getting closer by checking out all the suggestions you've received. I'm betting on a corrupt file or sample at the moment. Cold comfort, I know, but good luck!

This started happening to me 2, actually now, 3 weeks ago as well. Either way, everything was fine until 7.1 and even rolling back to 7.01 didn't help.

I've posted all my problems with this issue, and attempts to fix it in the other topic on this subject.
I just wish Apple would say something to us. It's their silence that is beginning to get to me.

Sorry Apple/Logic guys, but that's how I feel.

Hi,

I have been reading youre comments about the core audio message and wonder if you have any advice for me. I have a power G5 single 1.6Ghz, with 1.25G of RAM. A second hardive for audio and run logic 6 with and m-audio interface. I have about 5 or 6 tracks running in my song today (two audio and 4 soft synths- korg legacy and absynth, plus a couple of logic plugins) this is a pitiful ammount of tracks and devices, allthough i understand that the korg legacy and absytnth are cpu demanding. The problem has got worse since installing the lecagcy collection so obviously that has something to do with it but is there anything else that i could try to rermedy this problem? Apart from adding more RAM i am stuck for ideas. I have read and taken on board some of youre suggestions and am going to try them out (increase buffer size, audio hardware and drivers etc).

Also can i also say that i am very frustrated with being stonewalled by the logic and apple guys at the mention of this sort of problem. It is not unreasonable to expect a G5 1.6 single processor to run logic and four or five synth plugins is it? If it is unreasonable then maybe it should be clearly stated so people know exactly how much they need to spend!!

thanks john.

I have the same problem but am only using four or five tracks today. Two plugins the Korg legacy and Absynth and two audio and the ES1.

I have a 1.6 single proc. G5 tower and logic 6 with an m-audio ingterface. what is the problem guys!! Logic is useless to me like this. I expect to be able to run a little more than this!!

Also very frustrated at the lack of heklp from either logic and apple, it is simply a case of tough!! you have got youre system now live iwth it or buy another one and hope it doesnt happen again. If it wasnt for other users experimenting and trying out different ways to solve these glitches we would all be stuffed right!

Can youn recommend anything to stop the annoying "core audio system overload" message from appearing. I have a seperate hard disk (internal) for all my audio samples. Could this have anything to do with it?

cheers
