Logic initializes core audio twice, very slowly

Does this happen to any of you?

 

All my large projects that used to open quite smoothly in lp9 now open very very slowly in lpX. Almost every time logic does the whole "opening project" procedure twice, initializes core audio, loads all instruments and samples.... initializes core audio again... And after that everything is very clitchy for few minutes until the session finally starts to work as expected.

 

I even have some projects that crash at some point of that procedure described above, or crash when I hit play after it´s finally opened.

 

Also my Logic Pro 9 doesn´t work anymore after installing lpX, so this is very frustrating... (I did try to uninstall and delete carefully lp9 and installed it again, but still its not working. Crashes on startup every time.

What kind of 3rd party plug-ins/instruments are you using?

Have you bypassing them?

Yup. Definitely happens to me too. Especially on larger projects. Can't track it down yet either.

I've also encountered the slow project opening with automatic Core Audio engine reinitialize for no apparent reason. I haven't been abled to track it down to a specific 3rd party plug-in but maybe that's the issue.

Me too.

I have several projects that re-initializes Core Audio in LPX on load.

Just like mks said, especially on larger projects. Have tried to track it down without success so far.

 

Never happened in LP9 with the same setup.

Never tracked this down definitively, but these were my two suspicions:

 

1. Instances of East West's Play engine seemed to cause this for me sometimes (though that may have been fixed in a revision)

 

2. I noticed a difference in behavior depending on how I opened projects. Specifically, loading Logic first (set to load nothing on startup), then loading a project seemed to help. Double-clicking to open existing projects seemed to yield the double-load behavior more often.

 

Again, this isn't terribly scientific, but would be curious if either of these affect you guys as well.

Has anyone had any epiphany regarding the cause of this?

Hey all,

 

This is my first post and I've got to this forum by searching this issue at google. I'm experiencing the same issue mentioned in the first post. I've got a project running 120+ tracks at lpX including 32 Lives converted TC PowerCore plugins, UAD-2 plugs, Native Instruments plugs and many many other. I'm trying to solve this out myself too.

On Apple forums, there was a post that said you can avoid this issue by opening a blank project first. Haven't tested it out yet, so can't confirm. Also there was someone saying Native Instruments engine causes initialization to core audio engine in lp9 & lpX but can't confirm that either.

 

There was also a post that said you could launch logic without audio engine -> load project -> set core audio and it's sorted. You can launch Logic without engine by holding down control right after you click the image on the dock. This method didn't work for me.

 

I'm running lpX at 2.66 Quad late 2009 with 13Gt ram and Mavericks.

I see this occasionally too and didn't notice what caused it but also use 32 lives. I don;t really see a noticeable slow down other thna the core audio loading animation for a couple seconds. I'll pay more attention next time to see what link is common. Maybe 32 lives?

I'm not using 32 lives but experience the issue nevertheless.

Ok, so I'm back with some results which ain't good.

 

I opened up lpX with audio engine disabled (after clicking the lpX image, press crtl). Then I opened up my project with 120+ tracks and removed all plugins except one UAD plugin to see if it loads in and then drops off and loads back in again. And that's exactly what happened.

Initializing Core Audio came right up after the Audio I/O re-selection & project was loaded.

 

When my project was cleaned of plugins (except uad2) and track objects, I saved it. Then relaunch lpX. Same issue again.

I removed all the unused audio files, saved it and relaunch = no more initialization for audio engine. That was good result, except my project was cleared out.

Next I tried to remove the audio files from the original project = initializing core audio came with it, no help whatsoever.

 

So the big question is: Is the project itself corrupted by some event triggered by the user while loading in plugins or is it some sort of a memory leak / miscommunication with the core audio driver?

 

David, I heard you're dealing with Apple quite a lot, or then I'm wrong, but is this issue being noticed at Apple and are they investigating it? I'm open to share my parsed project with someone else to try it. Only plugin loaded: UAD-2 4K Channel Strip. Doesn't really mater if someone has it or not, the most important thing is to try if the Audio Engine resets itself while opening the project.

Are all of you guys using UAD?

 

I was just wondering if it could be an issue with UAD.

i have had the automatic Core Audio engine reinitialize for no apparent reason.. no UAD here.. if there is a pattern i cant find it.

I have also seen this issue. No UAD.

Are all of you guys using UAD?

 

I was just wondering if it could be an issue with UAD.

 

Yes issue here (more with 10.0.5 though) and yes UAD Apollo Duo on TB to Firewire converter. Sometimes UAD audio drops out in Logic, yet still works outside of logic.

Thought i'd add my tuppence worth.....

I've no bloody clue what's going on with my Mac any more. The Core audio constantly drops out for me. Every time I use Logic almost, I have to reset Core audio in the audio prefs pane before I can do anything else.

I do use 32 lives. But, I had this problem before I started using it. So I doubt it's anything to do with that..

Also, I've started finding that the audio now drops out on iTunes, general internet sites that use audio (sound cloud, youtube etc) too. So I have to go into the sound section in my system prefs as well now.

Getting pretty wound up by it all tbh.

Hate updates.

Happens at the moment when launching a bigger project. Sometimes when making an undo or unpack a region folder.

Same issue here. Did anyone solve that now? did anyone send a bug report to apple?

 

Cheers,

Still happens here. Never figured out the sequence or cause. I think it is just a Logic X quirk.

I don't know if this will help everyone/anyone. But my issues with having to reboot core audio disappeared when I deleted the supposed 'disc cleaner' called MacKeeper off (both) my macs.

Damn program is basically malware for Macs. DO NOT USE THIS PROGRAM!!

Any of those "clean your Mac" or "make your Mac faster" apps are to be avoided!!

 

They do more harm than good. It's not Windows, you know.

I'm seeing this exact issue still, especially on bigger projects.

Usually happens when I make an undo, or sometimes just randomly the loading wheel will come on and it will initialise core audio again.

 

I use at least one instance of Kontakt on all my projects. When core audio initialises, the grey box comes up from Kontakt to re-load the audio files. Very annoying when I have a few Kontakt instruments, takes a long time!

It started happening to me today for no reason. I've had too many plugins before and having gotten the disc overload error. But this is different because logic X will crash completely when initializing core audio.

 

I fixed it somewhat, seems steadily working now one I get it working but some projects are still are unstable loading. I just hope when I record for people I'm not struggling with it for hours.

 

These seemed to help:

1. I/O buffer size 1024

2. Large Process buffer range

3. Low Latency mode

4. Loading a blank project first

5. Plugged my Focusrite directly to my laptop instead of using a USB hub (Seemed to help a little bit, or at least remove some variables)

 

Now my complex template with like 30 plugins works and runs seemlessly for hours but ironically when I load the exact same template with all plugins bypassed it crashes. So bypassing isn't helping. Which makes me think it is struggling to load all the plugins (when it says initializing core audio) in time but then it'll timeout. A different plugin is the culprit every time which makes me think it is some sort of loading CPU issue with too much information being thrown at the computer and not a corrupt plugin issue. With a blank project it ALWAYS works changing from focusrite to built in audio core without crashing. So there is something in the template and my previous mixes that is causing problems. Maybe I need more RAM...

 

It's just strange because it was working the day before and I haven't changed anything. I could have just gotten a virus or malware possibly.

 

Audio Drivers? I'm using Yosemite 10.10 and I've avoided updating because it usually causes more problems than solutions.

I notice this thread is almost 2 years old. Was there ever any solution to this issue? I´m experiencing excactly the same problem. Overnight my Logic x projects are loading extremely slowly. It seems to take forever to load the plug ins

Have you gotten an answer to your question? If not, you may want to try the solution that worked for me.

Here's my post on the subject:
