I am only using 60-70% of CPU load...

Yes, I am using only 60 to 70% of CPU load. Why is there static here and there?


I have a Retina Macbook Pro

16GB mem

2.6 GHz Intel Core i7


Does this not cut it?


I am also using a bunch of waves plugins....


Any response would help. Thanks!

    "only" 60 or 70%? That is a lot! Even on very large projects/livesets, my Macbook doesn't even hit the 30% mark....

    Might be a good idea to try and optimise your settings (lots of tips available on the web for that) for audio use.

    Waves plugins are quite heavy on cpu though, so you might want to try some less heavy plugins to see if that is the cause.

    Also, try freezing tracks or bouncing stuff to audio, since big midi instruments can also use a lot of cpu power.

    Other tips that might help:

    - use a dedicated (professional) external soundcard.

    - install a 7200 rpm harddisk in stead of the standard 5600 rpm.

    - close other applications while making music.

    - check your preferences and make sure you only use the basic settings for your needs (like deactivating in- & outputs you don't use).

    - try optimising your buffersize.

    Hope this helps!

    i have the same problem on my iMac running with a 2,8 GHz Core i7 (Quad Core). Everytime the CPU load exceeds around 50% it starts producing small glitches. I've tried several audio buffer settings to get rid of this.

    Interestingly it doesn't help to increase the buffer size. With multiprocessor support enabled i get more cracks and glitches when i got above 128 (e.g. 256, 512 etc). Also I got more glitches when i decrease the buffer size (and higher CPU load then). I had to stick to 128, but i get glitches anyway although not so many (only every 1 or 2 seconds). 

    Of course this is very annoying and there seems not much more I can do with standard procedures.

    I have this problem too, where "Multiprocessor Support" is worse when enabled. My CPU spikes to 100-130% with it, with audio deterioration, while staying at ~30% without it and good audio reproduction. Interestingly enough the Load Distribution is not awful: 1 CPU is about 20% higher than the others, and half are idle. When introducing "Multiprocessor Support" all processors again another ~15% of work.

    Ableton Live Version 9.0.6, MacOS 10.8.5, 2.6Ghz Intel Core i7, 16GB RAM

    I don't want to upgrade because of instability in 9.1.x

    Guess I'll keep it off since it's better is all rep

    Hi all, 

    Please make sure to work through the following two articles, which should help a lot. 

    Reducing CPU load in Live: 


    Avoiding crackles and dropouts: 


    Hope it helps,

    I figured, having the macbook camera active (Skype, photobooth, facebook) creates this problem! When closed it stopped! I have no idea why but that was the case for me!
