SYSTEM OVERLOAD SOLUTION! MAYBE...

Hi guys!
For everybody who are fighting against this annoying problem!
I read about somewhere here, somebody wote about there is a folder:
Macintosh HD/Library/Audio/Midi Drivers
Somebody has drivers there, and somebody dont have.
In this folder i had two drivers: EmagicUSBMIDIDriver.plugin and EMUMIDIDriver.plugin
I dont know these two drivers are necessary or not, - i have EMU USB 0202 soundcard - but i tried, what will happen, if i take out this two drivers, just like that.
I put these files in a safe folder, in case if something problem would come.
This happened: NO MORE SYSTEM OVERLOAD ANYMORE to me!
All the Logic softwers and plugins works fine, no stopping all the time, no system overloads in every 5 seconds.
Also, often the iTunes running, because i always compare my music with another pro music, and no system overload at all!
=)
Only, when i tried to open Firefox with 12 tabs during playback.
=)
Try this too, and wrote to here, what is the result!
I hope it will stay, and it will help many other users too!

Two more tips from me: Be sure to NOT have a Software Instrument track selected when playing back. The instrument then is 'ready to be played' and therefore needs more CPU. If you select an audio track, aux track or a frozen SI track, it is easier on the CPU.
Secondly, set all audio tracks to *No Input*. That has ben reliably reported to make a difference too.
Thirdly (bonus) set the *Process Buffer Range* (in the Audio prefs) to Large.
Also, keep in mind that just muting a in the track header doesn't disable anything, the content is still streamed. Only when you mute the regions, the content is left out of the process.

Solution for "Error while trying to synchronize Audio and MIDI" and "System Overload" messages

Article for those who hate Logic error windows
Seen in Logic Pro 9.1.7 on Mac OS X Lion 10.7.4
and Logic Pro 9.0.0 on Mac OS X Snow Leopard 10.6.5
Logic Pro:
System Overload.
The audio engine was not able to process all required data in time.
(-10011)
Error while trying to synchronize Audio and MIDI.
Sample Rate xxxxx recognized.
Check conflict between Logic Pro and external device.
The search in the help given as follows: overload occurs when you use a lot of tracks and a lot of effects on them, and the synchronization is lost when the selected MIDI track for recording or playback. Yes, this is all that is written in the resources. And here are useful tips that have been found:
The Bounce function allows the entire instrument track to be recorded as an audio file. This bounced audio file can then be used (as an audio region) on a standard audio track, allowing you to reassign the available processing power for further software instrument tracks. For more details, see "Bouncing Your Project."
You can also make use of the Freeze function to capture the output of a software instrument track, again saving processing power. For details, see "Freezing Tracks in the Arrange Area."
These tips - about the timing. About overload - there are no tips, except as "reducing the number of plug-ins" and "increasing latency". Zero useful tips - I got two errors in the test project with a blank audio track with no effects, MIDI drums and standard synthesizer, it was no aux buses, and the entire project was only a single plugin in the master track.
Here is the configuration of my computer:
iMac12, 2
CPU: Intel Core i5 3,1 GHz
Memory: 4 GB
And here's a project that almost immediately stops Logic, all instruments and plug-ins with the init-patch, ie not the most demanding settings:
It's sad.
When this happened the first time, I could start the project only if the empty audio track has been selected, a track specially designed so that you can at least start the project. Then, this problem has evaporated along with the changing conditions of work and I forgot about it until the last case.
I was looking for the cause of the problem in the console and the system monitor for two days, and finally I found that Logic ping to the network frequently. I remembered the exact time of occurrence of the problem, and system logs revealed that the problems began immediately, as soon as I deactivate the service of the Internet.
Solution: enable the Internet, or add a new network service on a computer with no Internet. I just created the Ethernet connection to the ip address 1.0.0.0
Logic immediately began to sing.

Hi gabaghoul
Yes, it worked for me on four different OS and Logic versions (10.6 - 10.8 and 9.0 - 9.1.6)
It does not work in some cases, hard enough to tell in which one, but you can try, it very easy: go to the net settings and create new Ethernet connection to the ip address 1.0.0.0 and connect LAN cable to the port.
Also you can try to figure out what happens in your system while Logic error occured - fot that you just start Console and search "logicpro"
Pay attention to repetitive events in a console and events with suitable timing, not so far from error
The problem may be related to the GUI or system memory, sometimes turning off Safari (or Chrome, others browsers) might help.

i have an external firwire harddrive just for the audio projects which is 7200rpm etc and it has 500gb of free space on it!
i've already tried the pmset -a sms 0 thing, but that is only for laptops, their seems to be no solition for Mac Pro Desktops!
this is annoying.
hope someone can help.

and in laptops it is just working for the original builtin HD.
It shouldn't be there at all.
you set it off by (copy/paste):

Best solution to avoid System overloads

Hi
I just bought a MBP 2.4 17" and want to find out which is the best way for recording without
system overloads.
1) Audio (for recording) and Samples on 2 external(separate) FW drives
2) Samples on external FW drive and recording on Mac Book Pro
thanks in advance
criote

i actually learned yesterday, that locking tracks is a great way to free up CPU. what it does, is it writes to the hard drive. you can still pan and raise and lower volume, but to further edit you must unlock the track. so if you are building many tracks, lock the ones you're not working with at the moment, and play with the rest. then lock those, unlock the others to keep working. working this way is a wee bit slow, because you have to render the track to the hard drive. but it allows you to keep building.
Another great way is to use the bus. for example if some of your tracks have the same insert/plug-in, then use it on a bus instead of doing the same thing to each track individually. putting it on the bus, frees up CPU as well.
I hope this helps... I was so happy yesterday to find out that putting effects on a bus to many tracks not only helped my sound, but also freed up CPU.
just make sure that if you lock your tracks, you've set the song locators to where the song begins and ends... otherwise you might end up rendering a whole lot of nothing after your song is done.
all the best.

Well, if you are saying you have only 2.78 GB's of space on your hard drive, then you'll want to have more. You should leave about 10-15% of your drive free.

I'm running LP8 - I have an IMAC OSX 10.5.5 - 2.4 processor - 4 GB RAM - M-Audio Fast Track Pro interface (USB direct to MAC) - I do NOT have an external hard drive ( sounds like I should ? - although I was told by others my system would be sufficient) - I use ALL instruments/track options ( midi etc) and will need to in the future - I want to be able to run a full music project 10-15 tracks. So far I'm running 4-5 tracks -(1) midi - the rest are audio with little to no effects ( in one project I'm using an LP8 template but deleted most of the tracks to cut down on the load ). Don't know if I can freeze these tracks-I'm new to this - thats why I'm looking for options ........ i was also using a 3rd party software in the project - Steinberg Groove Agent 3 (drums) but it was giving me the same error ..even when it was the ONLY track in the project....(its not fully compatible) - however I was finally able to create a full drum track with GA3 - play the midi data back - and record it to an audio track - therefore deleting the midi data I was having issues with and keeping the drums.... hope this helps?

Perfect. Well here are some suggestions:
1) Logic 7, 8 and 9 all have a "freeze" function. Logic 9 has a new "bounce in place" function which I haven't used yet. These will make temporary audio files of your MIDI instruments so that you are able to play them as finished audio for the most part and free up CPU power. ( I haven't yet used "bounce in place", I just got Logic 9.) This will help with MIDI instruments quite a bit, and you can still go back and change them by un-freezing... I guess "thawing" would be the proper term.
2) The reason I was asking about your audio interface is because I was wondering what you had available. You very definitely want to record to a non-system (on that Logic nor your operating system are on) drive. Firewire is much superior to USB, which is why I'm glad to hear you are using USB as your audio in. By using Firewire in and Firewire out, on an iMac, you would be halving the bandwidth. In your case you are not.
You will add very much stability to your Logic work by adding an external Firewire drive and recording audio to it, and working on Logic projects there! If you have the money, I'd go with Firewire 800, which is frankly overkill, but why not. Firewire 400 drives will work fine for you. Add one and many of the overload messages will disappear, simply because right now you are pulling information from (in the form of calculating what the virtual instruments and Logic are doing) and writing information to (in the form of writing what those instruments and Logic are resulting in) to the same disk.
Try these two things and get back to us. I think you'll be very happy with the results.
It's also important to pay attention to your buffer size. When it is not important for you to play with it in real time, you want to make it be 1024. Otherwise as low as possible. So when you are recording audio to a MIDI drum track, you'd want it to be very low so you can play along accurately. When you have all that done, and are editing MIDI only, then put the buffer higher. When mixing, put it higher.
Let me know how this works, good luck, L

Ok Great - Thanks - makes sense - I was using a Lacie with Protools an my PC ( it recently crashed) - I was under the impression I would have enough processing power with out it on the MAC.
Looks like I can pick one up for just a little over $100 ( I'm rolling in that kind of cash) ... please clarify though - you stated: "Firewire is much superior to USB, which is why I'm glad to hear you are using USB as your audio in. By using Firewire in and Firewire out, on an iMac, you would be halving the bandwidth. In your case you are not" ....are you GLAD to hear I am using USB as in - We may have found the problem .... go external to free up processing ? Please confirm.

As stated in an earlier reply, if you only have 2 or 3 gigs of free space on your Mac hard drive, processing power is NOT the problem. Your boot disc is way too full. You should have at least 20-30GB free.
Running a second drive for the audio side will, of course, help, but you MUST clear out the main hard drive (or fit a larger one) before you run into even more serious problems.

Well, you have enough processing power, that isn't the issue. All the processing power in the world won't matter if you have 64 megabytes of RAM, there will be a bottleneck. Another bottleneck is with data transference. Like I said, when using a single drive to transfer date from as well as to- which is what you are doing when you are using Logic, running within the scope of the operating system, and hosting virtual instruments, all of which is writing the resulting audio information to the same drive, at the same time, then you are creating another problem. But you don't have to do that, by sending the audio written to another drive other than the one the audio is being generated from.
In other words, your processing power is both faster than and irrelevant to the physical limitations of the hard drive itself.
Another bottleneck would be if you were recording tracks on a Firewire in, and sending that to and external Firewire drive out. This is one of the limitations of the iMac, there is no way to add what is called another bus, which is simply another pipeline for data transference. You can get around that with a Mac Pro, in which you add another internal hard drive, which connects directly to the motherboard, and has its own bus. Or by adding another Firewire PCIe card, which will add another Firewire bus, again, with its own data transference. On an iMac, you have one Firewire bus, and one USB bus.
Clear? You can imagine these as pipes of water. The more pipes you have leading to and from a location the faster it will go.
USB, in your case, is a dedicated pipeline in. Nothing (well, your mouse, maybe a flash drive) is using that pipeline. Your Firewire is a pipeline out, in this case- you could reverse this, it doesn't matter*. If you use Firewire in and out, then you are sending water flowing in both directions in the same pipe. It will work, but not as well. By adding a dedicated bus, you would be adding another pipe to flow in one way, while the original flowed the other way. No impedances.
I don't see why you can't use the Lacie drive you already have, though. It's quite likely your crash wasn't due to it. No need to buy another drive, if it's Firewire, anyway. Just give it a shot- this isn't a cure all, but just good audio practice. Let me know how it pans out. Good luck, L
*Firewire is better than USB in all situations. But you seem to be going a track or two of USB audio in, so I'd use USB for that. For light use it's fine. Then you can use your superior Firewire bus to write the audio to the external Firewire drive.

L - Thanks for laying that out in simple terms - learning a ton and loving it ( when things work) - I will pick up another Lacie - my old Lacie for my PC crashed - I'm better off starting from scratch ( I'm still trying to retrive some data of the old one) ... I'll let you know how it works. I would have got an external drive outright but the Logic Certified guys at Apple told me I would not need one - sounds like this is the big problem. I'll use the freeze method when needed also....... maybe I'll have better luck with Groove Agent 3 with the external drive.
Much appreciated-

Groove Agent 3 loads samples into memory so I doubt if your luck will change.
The -first- thing I would do is clear some space on your hard drive, my feeling is that OSX is writing swap files and the drive head is working overtime to try and find free space to write. That in itself could cause an overload.
Free drive space now or expect more problems than you're currently experiencing.

Your Firewire is a pipeline out, in this case- you could reverse this, it doesn't matter*. If you use Firewire in and out, then you are sending water flowing in both directions in the same pipe. It will work, but not as well. By adding a dedicated bus, you would be adding another pipe to flow in one way, while the original flowed the other way. No impedances.
I don't see why you can't use the Lacie drive you already have, though. It's quite likely your crash wasn't due to it. No need to buy another drive, if it's Firewire, anyway. Just give it a shot- this isn't a cure all, but just good audio practice. Let me know how it pans out. Good luck, L
*Firewire is better than USB in all situations. But you seem to be going a track or two of USB audio in, so I'd use USB for that. For light use it's fine. Then you can use your superior Firewire bus to write the audio to the external Firewire drive.

Groove Agent 3 loads samples into memory so I doubt if your luck will change.
The -first- thing I would do is clear some space on your hard drive, my feeling is that OSX is writing swap files and the drive head is working overtime to try and find free space to write. That in itself could cause an overload.
Free drive space now or expect more problems than you're currently experiencing.

System Overload & How to get the best G4 Performance

Okay all you Logic and OSX Gurus. I need your help. I've finally made the LOGIC leap from OS9 and have hit the SYSTEM OVERLOAD wall like many of you before me.
I've been pouring over this, and many other Forums and Blogs, for about two weeks now, and have tried many of the fixes / solutions to no avail. I estimate I'm now getting about 25% of my OS9 Logic performance from Logic in OSX.
One specific case in point is this. A four minute song sketch. No tempo changes. Four midi tracks, 6 Audio instruments and 2 EFX (1 Guitar Amp Pro, 1 Space Designer that's no even being used).
I have unsuccessfully tried to Bounce this to disc for two weeks now. The AUDIO and DISK I/O Meters barely register until the GUITAR AMP PRO track brings the AUDIO METER up to about 1/3rd usage. At various points in the Bounce the G4 will completely FREEZE, and I will have manually restart.
THINGS I HAVE TRIED, and continue to try are:
- Repairing Permissions
- Trashing Preferences
- Updating MOTU Drivers
- Changing Processor performance setting - which I cannot do BTW, because my system does not seem to support this option.
- Closing all Widgets
- Freeing up more Space on my Mac OSx startup disk (I now have 78.41 Gig available on a 114.49 Gig drive)
- Run Cocktail to clean up System logs and temporary files
- FREEZING TRACKS as a temporary 'fix'. This did nothing BTW but add more strain to the CPU and I still had about 1/3rd the usage with my GUITAR AMP Plugin (and it still crashed).
- Increased AUDIO BUFFER to 1024
So, (and I guess this is really two sides of the same question)...
1) How do I FIX this SYSTEM OVERLOAD problem, and
2) How do I "optimize" my Dual 1.25 G4 in order to get the best performance possible out of LOGIC PRO?
OTHER QUESTIONS I HAVE ARE:
- Does the G4 have the processing power needed to run LOGIC PRO?
- I'm confident adding RAM will "help" (can't hurt), but am I really dealing with a RAM Problem here or, again, can these processors really handle it?
BTW - I'm not looking for an excuse to go shopping for a Quad G5 (I mean who needs an excuse... . But, I'm really trying to determine if at the end of the day I will spend money on RAM, Hard Drives, whatever..., and then still be frustrated and end up shopping.
- Are SCSI drives a problem with Tiger / Logic? These Cheetah drives are fast (10,000 RPM), reliable, and have been great drives to record on. I'm trying to do this simple bounce to one of the Cheetahs and as I said it's just not happening.
- Does the startup volume size effect performance?
- Does the amount of free space on the start up drive effect performance?
- Firewire 400 vs 800? My sample library is on the Firewire drive, and I'm thinking this does not pull a lot on the CPU as these get loaded into memory before playing? Am I right about that? It is Firewire 400.
A long letter and a lot of questions. I thank you all in advance for any answers, guidance or direction you can give. Please also let me know if there is something I HAVEN'T asked, looked at or should be doing.
Best,
Kevin

And after months of using Express, and a week of
using Logic, I hadn't had a system overload until
today. Now I'm having them all the time. It wasn't a
set up change, it wasn't running on the battery, it
wasn't running software monitoring, it's set up with
512 i/o buffer, medium processor buffer. And it
wasn't brought on by number of tracks - that's for
sure. After it started happenind and I took a break &
came back, I was sitting on my couch, Powerbook in
my lap, tapping a beat in with the onscreen
keyboard.... a SINGLE instrument, mind you. NO plugs,
no other tracks of ANY kind. And it happened.
There's a lot of great, relevant and very helpful info on this forum and it all helps and it all counts. But..... so many people are suffering this when moving up to Pro 7 from either Pro 6 or Express. One expects a change in system load when a major update comes along but more and more people are reporting that simply recording 1 or 2 tracks of audio, pure, no plug-ins or EQ is causing an overload whereas in the previous version(s) this was easily accomodated. This, you may have guessed, has happened to me as well. Are we to accept in 1 version increment (albeit a major one) there is such a massive increase in demand from hardware that you cannot record a pure no-plug-in stereo track? When going back to 6.4.3 it will happily record 8 at once, let you EQ and reverb and then do another 8 AND then another. With no troble at all.
It is pointing more and more towards fundamental flaws in the programming. Did L7 come out too soon? Are we just beta testing what is pro software? We are only on 7.1.1 and 6 went to 6.4.3 but at no stage was it this bad at the fundamentals of what the App is for. I love Logic, I really do, but I think, even with all the great help we are fighting what Apple should be addressing. Not that you can find/contact/talk to or get any sort of response from them.
I have tried but have gone back to 6.4.3 until 7.1.2 or even 7.2 appears, but I'm not paying for 7.2. My £200 upgrade from 6.4.3 is now sitting on a shelf desperately wanting to use it.

Logic Pro X - Disk is too slow or System Overload. (-10010)

Hi there, I'm a professional music user and recently switched from Pro-Tools to Logic due to PT11's lack of third party plug-in support at the moment. I was looking forward to leaving behind the error messages of Pro-Tools for the supposed plain sailing of Logic. However, after installing Logic X and starting a new session with one track of audio and 4 tracks of software instruments, I'm receiving the following error message when attemping to record a part on one of the software instruments. 'Disk is too slow or System Overload. (-10010)'
I have an 8 core Mac Pro with the latest version of Mountain Lion, 16GB of Ram and a 250GB SSD boot drive (which Logic is installed on). My sessions are ran from a secondary 120GB SSD which has 110GB of free space on it and my sample libraries are streamed from another internal 250GB SSD and a 7200 RPM 32MB Cache SATA 3.0Gb/s 3.5" Internal Hard Drive. My interface is a Focusrite Scarlett 6i6 USB 2.0 and my I/O buffer is set to 512.
It is completely unacceptable to me that I should be experiencing error messages with this set up and a 64 bit DAW, particularly when the session in question only has one track of audio and one instance of East West's Play engine, spread across 4 software instrument tracks.
Has anyone else experienced similar problems or have any ideas as to what the solution could be? I'd really appreciate any advice.
Cheers,
David

Just as a quick followup....
After doing a little research online it seems the Scarlett is one of those USB2 devices that has issues with how Apple changed their implementation of USB when they released Macs with USB3 interfaces and put this updated implementation into Lion and later Mountain Lion... and that this is probably why some people have major issues like the OP is reporting and why other's do not. It depends on the hardware/OS X version combination as to if this issue rears it's ugly head.
Oddly enough some Win 8 users are also reporting similar issues with the Scarlett for much the same reason.
The March 2013 Scarlett OS X drivers are intended to 'alleviate' this issue but Focusrite have stated it is only to 'alleviate' in some instances and not completely fix the problem for everyone who has it,.,..
However, the good news is that Focusrite have released some beta drivers (v1.7b2 and later b3) which seem to work better for some people than the last official release...
Mac Only.
General stability/logging improvements:
- Improved audio stream syncing
- Fixed bug which results in occasional inaccurate timestamps
- Improves sample rate switching
- 18i20 stream formats now switch automatically
- Fixes Forte streaming at 176.4/192kHz
You can find them here..

Note: These beta drivers again seem to only alleviate the issues for some people and not all but it has got to be worth giving them a try I would think...

Disk is too slow or System Overload. (-10009)

Hello all,
I'm running a G4 PowerBook, with 1.67 GHz, and 1.5 GB DDR SDRAM. My Logic set-up is Logic Pro 7 and a Motu 828mkII.
My present Logic project contains 7 tracks, with EXS24 through 6 tracks and Sculpture through the last. The instruments were triggered through a midi keyboard.
While trying to score a short film, I keep running into the following error:
CoreAudio: Disk is too slow or System Overload. (-10009). The error happens while recording and during playback only. There are times when I do not recieve the error message, but playback is terribly jerky and I'm unable to clearly see exactly where I am on the timeline.
I have searched for similar errors on this site and cannot seem to find an answer. I imagine the solution is changing the way I have my I/O setting in the CPU usage. Am I on base?
I'd appreciate any help,
Kris

Hey Cyril and 25G's,
Well I went out and bought a OWC Mercury Elite Pro Firewire 800 with Oxford 912. I transferred the EXS Factory Sample files to the OWC drive. Then I deleted the EXS Factory Sample files on the OS hard disk. Then I created the alias for the Samples and placed the alias back in the Logic file under Application Support on the OS hard disk.
The alias' seem to be working because the Logic project works. The only problem is that it is still terribly jerky.
The CPU is maxing out while the I/O meter is not responding at all. Could this be the clue to my problem?
(Also, Cyril, call me stupid, but I cannot find the Virtual Memory portion in the EXS Preferences.)
Thank you for all your help. (I am a bit slow myself when it comes to Logic and the proper steps to de-bugging a problem. So, very detailed explanations are appreciated)

Disk is too slow or System Overload.

I was working on a project that had a little over hundred tracks, and got this error. I thought that it was understandable, as I had many tracks(even though I was only recording one), so I started a new project to record it, with only one track. But I still got this error when I was recording one track, with no other tracks in the project! How can I fix this?
Here's the complete message:
Disk is too slow or System Overload.
(-10008)
The sudden motion sensor may have parked the hard drive head, or the disk performance is not sufficient to read or write all audio tracks, or the system was not able to process all data in time.
I run this on a 27" iMac with 8GB ram and 7200rpm, which should be enough to play and record many tracks.

But you didn't shut down Logic or (sometimes best) restart your machine in between ? Often, data gets left in memory and it hasn't had any particular command to clear it otherwise - a lot of allocated memory can be still considered as 'used'.
Well, maybe, but that aside,

- hopefully you're not doing that just using your internal computer's drive - if you have, you've been lucky so far.
If you're into Logic it is a well established fact that this message can appear for so many different reasons and its not possible for me to know what goes on with your machine - there are plenty of articles on this forum and LogicProHelp as well as the very concise and accurate (but not always as explanatory as I'd like it to be) stuff on this Apple website.
That's all I can offer at the moment until we have some more technical information, in which case there are others here that may have particular insights as well, so you're gonna have to take it from there because there is no one answer.

"LOGIC PRO X: Disk is too slow or System Overload. (-10010)" This is the message that I was having since two weeks ago with my Logic 9. I updated two days ago to Logic X and I am still having the same problem.

Umm,, no offence... but what is ridiculous... is you didn't troubleshoot the original problem but instead you assumed it was a LP9 problem so you updated to LPX which is still in its early days and is likely to be less stable than LP9... rather than more so!
So.. Here's the thing....
LP9 was working fine and then stopped working normally according to you. Therefore what changed at the time LP9 stopped working normally?
Here are just a few ideas to think about.. for around the time this started..
Did you update Logic Pro 9... OS X... Drivers for Midi/Audio or other connected devices?
If you did, did you then restore from a backup you made prior to these problems occuring and what happened when you did so? (assuming you do make backups of your system?)
Did you install any new Apps on your Mac?
Did you add a new Hard Drive? How is it formatted?
Did you start recording or creating music in a different way to how you used to before the problem started?
Have you started using a different SI or FX plugin or plugins.. More or different FX for example.. Did you install a new version of a plugin?
Is all your software legal? (Have to ask because some people install all kinds of illegal plugins and whatever else.. and have no idea how the 'cracks' work or what they might affect/mess up/conflict with in the process)
Have you looked at the System logs to see if anything is happening out of the ordinary when you get these messages?
Have you looked at OS X's Activity monitor to see if any app or routine is kicking in hard when you get this issue?
Basically, you need to think about and look for what changed... because something apparently changed to suddenly cause these issues...given you said you didn't have them until a certain timeframe and some of the questions above, I hope, will get you thinking..
....and maybe a few of the others here will come up with other ideas and suggestions to help you...
Good luck and let us know how you got on...

Constant system overload errors

Since yesterday I can't play any project anymore. When I hit play the projects plays for two seconds, slows down and a system overload error pops up saying 'system overload or disk too slow'. Logic crashes after that.
Nothing on my system has changed, no new plugins, no system changes. Many of the project files are on an external drive but it's working nicely and is not in sleep mode or anything.
Any tips?

I am not having system overload, but I do want to comment on the CPU meter. I noticed last night that running 3 tracks rewired through Reason 4, and an EXS instrument, my Logic 8 CPU meter indicated one core (second one) at 60-70% at times, with the other core (first one), barely being used. While running this, I launched Activity Monitor, and then hit "CPU" to watch the activity. Guess what, Activity monitor showed no perceptible difference between core usage, with both running at maybe 20-25% for the whole system, including Logic 8. I wonder if Logic 8's problem with system overload is simply a bad monitoring scheme. It is clearly wrong. I can imagine that if I had one or two more tracks running, I would have hit a limit, even though Activity Monitor would have shown my cores at less than 50% usage. Lame, Apple. Take care of this.

"Disk is too slow/system overload"??? Help!

Hey
I'm running Logic Express on a G4 with OS X 10.4.10. My processor is 450 MHz, and my memory is 896 MB SDRAM. When playing back around 6-7 tracks, i get a message saying:
"CoreAudio - Disk is too slow or System Overload (-10010)"
or
"CoreAudio - System Overload. The audio engine was not able to process all required data in time."
I'm assuming that this has something to do with my processor being too slow, however, according to the logic express requirements, i have much more than required. Or this could be a problem with RAM maybe, considering i only have 896 opposed to the 1000 needed.
Sorry if this is a noob question, i'm new to macs in general. I'm just looking for answers because this is keeping me from doing what i love. Any answers appreciated!
Thanks!!
EDIT: I'm using a presonus firepod for an interface, if that helps.

I'm not sure where you read the system requirements for LE8, but looking at my box I see that you need a "1.25GHz or faster PowerPC G4 processor (and) 1GB of RAM." Keep in mind that these are minimum requirements.
Unfortunately, the processor is your main problem . . . LE8 requires a processor almost three times as fast as your 450 MHz. Also, as you pointed out, you don't even have the minimum 1GB of RAM. You do have the proper OS, but I don't know if you have the minimum required 6GB of available disc space.
Other than upgrading your processor or buying a new computer, the only other suggestion would be to make sure you record to an external drive but I'm not sure how helpful that would be in your particular case.
I'm sorry I couldn't be more helpful.

Will adding more RAM reduce system overloads?

I'm running Logic Express 8 on a mac mini (core 2 duo) with 2GB or ram. I was thinking of adding more RAM (4 or 8GB). I tend to see "system overload" errors often. Generally, rebooting seems to fix the issues. Do you think adding more RAM would make any difference? Generally I have maybe 15-20 tracks.
Thanks

No, unless the overload has to do with RAM, which it ususally hasn't.
Nevertheless, adding RAM is a very good idea to help instruments with high RAM requirements like EXS24.
To reduce system overload:
- let Logic be the only open application
- if necessary, raise the audio buffer in the preferences to the next higher value.
- while playing back, have an empty audio track (or the master track) selected.

System Overload & "Save as" crashes

I'm using Logic 7.0.1 on 10.4.2, with Pro App Suport 3. When I begin to play the piece, I get the "System Overload" message every few seconds. (The audio engine was not able to process all required data in time. (-10011). In the CPU window, the right column is never active, while the left column mostly says at 1/4, sometimes spiking to 3/4's. I press the "continue" button and begin to play again. The CoreAudio alert repeats a dozen times as I continue through the piece until I reach the last note I've been able to record.
Then, I can suddenly play back from the beginning of the song, all the way through without the error message at all. It is as if the computer stops when it tries to process each new sample, but once it has played through all of them, it handles them easily. However, once I can play the whole piece, adding a new sample (a large sample like performance legato) doesn't trigger the alert message. I only get it when I am first beginning to play through the piece.
I have an external Firewire HD by LaCie to store my samples, so that on the laptop, 37.91 GB's of 55.76 GB capacity are available. I use EXS 24 samples only, Solo Strings from VSL, with Core Audio (till I get more acquainted with Logic 7 and decide what I need). The piece is a string quartet, so even though I have 80 samples on different tracks, there are only 4 notes playing at once at any time. The only plug ins are platinumverb and gain, and the problem continues with these plug-ins "bypassed."
I have been reading the discussion board and took advice given about upgrading to Logic 7.0.1, and getting Pro Application Support 3.1. The problems I experienced have not been corrected.
I decided to use CoreAudio until I became more familiar with the program, and I realize with a three year old laptop, I must be pushing the system to the limit. But then again, it plays easily once I have slugged through the error messages. I ereased my HD and reinstalled Logic a few weeks ago. That did not fix the problem either. ( I upgraded to 10.4 to use Toast 7, but then I was unable to use my modem. After 72 hours of Apple support trouble shooting via telephone, I was told to erase my hard drive and reinstall everything. I did so and the problem wasn't fixed. I then talked to someone who knew of a bug in 10.4. I didn't have to erase the HD after all. I was told the bug was fixed in 10.4.2)
The second problem involves saving. I save this piece as a "project." I can use the "save" option without a crash, but 99% of the time, if I use the "save as" option, I get the "beach ball of death" and send yet another report to Apple.
How is my laptop able to process the data in time once I slog through all the alert messages telling me it cannot? Does anyone know of a "save as" fix?
Much Obliged!
Billy

I'm not sure if you have this, and mis-typed or something, but Logic 7.1 (the update you pay for) and the 7.0.1 and Pro App Support solved this problem for me. However, we installed them all at once so I don't know which fixed the "Save As..." glitch....
Regarding the other query, I sometimes get this too - the computer seems to think there's too much information even though it's already been playing it all, and even if you mute all but one of the channels! (in fact - I think I recall it refusing to play even when all tracks are muted... christ...)
Generally I have to restart the app (and maybe the computer). This always does the trick for me.
Hope this helps,
Best,
Mickey.

The best DAW for Logic and big sample libraries... no more system overload

I'm planning on going big and getting the Mac Pro Two 2.66GHz Quad-Core Intel Xeon, 16 GB of RAM and add two additional 1 TB drives, one for samples and one for projects. It's been suggested that I include a RAID 5 and that it will make streaming of the samples faster and also safer and more reliable for backing up data.
With my current setup I constantly have to freeze tracks of sampled instruments or I get system overload.
Do I need RAID or am I better off without it?

Gabe Garza wrote:

I'm not sure why you consider this a bad thing.
Having to constantly freeze/unfreeze takes time and disrupts workflow. It's a good option to have if you need it, but much nicer if you don't.
Johnny,
I would strongly advise against diving straight in with 16GB of RAM. There are a lot threads around that discuss how much RAM Logic can even recognize, you should check them out. I don't remember the details very well, but I feel like 16GB was more that it can handle (maybe that was just for ESX...). In any case, don't buy a Mac pre-installed with all that memory; Apple charges way too much for their RAM, and you can find perfectly functional, guaranteed RAM from third-party sellers. I bought my Mac Pro with the base amount of RAM and have added as needed, and I recommend you do the same.
When you play your projects, look at your CPU window.
Look at the Audio and Disk I/O meters.
If Audio is peaking, you need more CPU's
If Disk I/O is peaking, a faster I/O on your hard drive is needed.
I would also recommend doing this. Are you getting "core audio overload" messages, or another type? If you get core audio overload messages while your System Performance meters aren't peaking (or getting close to it), getting a faster machine isn't necessarily the answer. Core audio overloads are kind of tricky--some people with slower machines get them rarely, others with very fast machines get them often. If you haven't read up on this issue, I recommend you do so.
I'm not too savvy on RAID arrays, but I have a few thoughts. How likely are you to need your PCI slots for other cards? The specs for the Mac Pro lists 3 PCI slots, which I believe means 3 empty ones, i.e. doesn't include the one that holds your graphics card. Do you expect to add a second graphics card? PCI based audio interface? Anything else like that? A RAID setup will occupy one of those PCI slots, just keep that in mind. Second, while a RAID 5 array is a pretty secure way to store your data, you ought to have an external backup drive anyway, so maybe it wouldn't be worth it ($700 for a RAID card, yikes!). Lastly, it's likely that any of the most popular 1TB drives (search barefeats.com for some articles on these) will be sufficient to do what you need them too. I don't know how involved your Logic sessions are, but I've never maxed out my disk I/O while using my Western Digital Caviar 640.
