CPU Error

Posted: Mon Nov 26, 2007 5:40 am

If you have updated your OSX to the latest version before Leopard, then fixing the pre-binding might also help. Actually, you should not update your OSX unless Digidesign tells you it is safe. You can find details on their site.

I will try what VonRock wrote too.

haven't got the new OS yet. Are you having a similar problem?

Still iffy on the trash the pref (lack of competence) thanks for everything thus far.

The article suggests that you MOVE (not copy) that file onto your desktop if you are unsure about this process.

You could just rename it by appending a letter or number to the file name, or changing the extension (that's the part after the . )

By trashing the preferences of a particular program, you will loose any of the 'out of the box' settings that you have changed. The program will remake the file when you start it up again, just like the first day you installed it.

I wimped out and called mac support, they helped me to "trash the prefs". I'm about to start work on a new song tonight so i'll know if PT is still acting up.

SWEET MERCYFUL F@%K!!!!!

It's still doing it. Lets reiterate shall we. I have one track in pro-tools with no plug-ins, when I play it back an error comes through saying to increase the hardware buffer even though the hardware buffer is set to its highest level. session is 24/44k. To remedy I've trashed the prefs, re-installed pro-tools and updates, passed tech-tool deluxe, repaired disk permissions on my HD. WTF, WTF??? I am so over-frustrated with this problem. Help me out what haven't I done. My whole setup is completely useless now (it sucks now because I have a ton of free time for recording now).

I lost my mac setup disks but new ones should arrive at the end of the week. I guess theres a setup utility that checks the RAM.

All my gear worked fantastic for a long time. WTF?

Sad

Someone already asked you - do you write audio on extrernal drive ?
Or on your iMac internal HD ?

internal HD. Its all fucked today, h/w buffer is underflowing instead of overflowing, the clocks between the mbox and protools are out sync even though they are set to the same setting. I guess i'm not meant to have a nice recording setup.

If it is the system drive no wonder you get CPU errors. I don't want
to generalize, but all people I know to use ProTools use an external FireWire drives as "write" volumes.
So, how many internal HDs do you have in your iMac ? Not the
partitions, the physically separate HDs ?

none. I just bought a macbook thats slightly faster but less hard drive space so I will be getting a ext. HD.

Thanks costy for your observation, I have been learning so much stuff from this post.

I just a search in machelp about partitioning a HD. It is something I have to do when I first load the OS on the machine. This is not something I'm keen of doing again. I spent all last weekend reinstalling the os on my old iMac and new macbook, it was lengthy to get this new computer up and running with all my programs and settings.

So let me get this straight, having an external drive is similar to having a partitioned HD? And you would specify this in Protools preferences?

No, partitioning a hard drive is really no different than having two really big folders on the same drive - it won't help your issue.

Don't bother partitioning it, get an external.

Edit> I haven't bothered partitioning in a few years. There are a few reasons to do it - a separate place to backup data, quicker defragmentation (which supposedly isn't a problem in Macs), security in the event of a virus, etc. But speaking from a DAW standpoint, doing so is not going to solve the issue of you writing to the system drive and bottlenecking the machine.

When you partition a hard drive you obviously aren't adding any more read / write heads, nor are you physically disconnecting it from the system folder. A hard drive reads chunks of data in a random fashion. The problem, even if it's partitioned, is that while you are telling it (in the DAW) to write chunks of audio, it also must occasionally read and write other chunks in the system folder (virtual memory, etc.).

Therefore, to sum up, it is far better to have one dedicated drive that is reading and writing to the system while another is dedicated to reading and writing your audio data chunks.

Gotta have an external drive, OSX will allways use part of your system drive for virtual memory, when you open PTLE more virtual memory is required.

Then if you attempt to record and playback tracks, your bottleneck will be the internal drive.

If the disk usage is heavy, OSX may delay PTLEs access to the drive, so it can do housekeeping.

Having a dedicated audio drive, will allow OSX to operate without interuption.

Cool

Word up, I guess I know my next purchase.

Yea, if you write audio on system HD you suppose to be screwed.
Read manuals, man. And, make sure you get an external HD with
7200 rpm, 2 FireWire slots, and fanless.

I had so much progress last night. I was using reason, safari, itunes, a ton of plug-ins, automation and all the goodies. It was a perfect session. Today not 10 hours later, I'm getting all those HW buffer issues. I have to wait till after xmas to get a ext drive.

My god how frustrated I get with pro-tools. Every time I go to "Record" in PT, issue after fucking issue arises. I have had outstanding results for the the last 2 months. I just finished a song.

I started a new song. I'm 3/4 the way into it and the low latency monitoring is F-ed. Isn't it supposed to let you hear what you are recording as you record it. Not on my machine. I am trying to lay down a guitar lead and i have to monitor with latency. GRRRR! Theres F-all in the manual on LLMM.

I repaired permissions and trashed the prefs. I recorded all the audio on an ext. drive (western digital). Why does pro-tools LE have to suck so much?
