Logic Pro X CPU Overload

What audio interface are you using?

Did you also upgrade to Mountain Lion at the same time as you installed LPX?

If so, did you check if your audio drivers are Mountain Lion compatible?

I have the same problem - all new MBP Retina 16 GB ram + SDD HD Apogee Quartet all updatet , but i dont have the problem in Mainstage 3 ?? Hope they fix it soon , its a lot of money if i dont work stable . BR NK

This is obviously a problem with your system or audio interface, no general problem to fix. I use RME card, rock solid, guess Apogee should be as well. Same computer as you

Can run 50+ tracks at 32 samples incl plugins !

eeveeayen,

Have you installed anything else that uses the CoreAudio systems in the background...

Something like Soundflower, Boom, Noiseblossom, Wiretap, Linein, Audio Hijack, Jack or anything else audio related that runs in the background and is used to change the routing of your audio... If so, quit it or uninstall it and test again...

if that doesn't help.. quit any background apps.. so that just LPX is running and nothing else (apart from Finder of course) and test. Also make sure nothing is running on startup like Anti Virus software...

The fact you get this issue using just one software instrument, your CPU isn't showing any spikes and you have plenty of onboard RAM makes me think it is something else unrelated to Logic Pro, that is running in the background, causing this issue as normally, that wouldn't happen....even when using the internal Audio hardware..It is not a common problem based on what you have described as happening and what you are doing. If you were using lots of tracks, plugins etc.. then that could be the cause.. but a single SI plugin, no.

One last question.. When you said it even happens when you use just one software instrument, which software instrument? One that came with Logic or a 3rd party one? Any FX plugins beiung used at the same time? Againif so, which one(s)

No , i was starting all fresh with a brand new MBP Retina and a fresh download of the new LPX , amd a brand new Apogee Qartet nothing else , and the problem still remains , now i am starting to download my stuff from Native Instruments and Spectrasonics , so it was and is just single instanses of Logics own instruments , i have tryed without Apogee to and its still the same , so it must be something internal , but i cant figure it out . Thanks for youre reply .BR Niels Kimmer

I have now tested with Studio One 2 Pro , and kontakt 5 on the same setup , and there are no cpu overload and no kliks and pops , so its not Apogee Quartet , its a problem with Logic pro x , i have problems with Logoc instruments also , notes not playing , the problem is not there when using Kontak 5 ? So i gues i have to use Studio One Pro until i have a solution for this , maybee i have to dellete the HD and reeinstall from scratch . Anny suggestions ? Sory fro my english writing .

As has been said in this thread, I found the issue to be a driver, I had been suffering intense CPU spikes in logic 9 and x, I have a iMac 2.9ghz Intel i7 with 16gb ram and 1tb hard disk, granted I only had about 100gb left on the HD and its messy... So I cleaned up the hard disk so I have 300gb and the cpu spikes in x were still bad, there are only 10 tracks and only running with compressors and eq on them.... Yet there was so many artefacts it was unreal, I recently upgraded to lion and didn't click about the driver... I have a motu 828mk2 and checked their website and downloaded the new drivers they have put up.... And hey presto no CPU spikes and CPU usage across all cores now as opposed to just 2 which resulted in spiking!
