Reducing CPU usage using a Macbook Pro OSX core i5 2.4Ghz 4G RAM.

As I start developing my Ableton project and begin to use more samples, effects (especially with my drum rack) my CPU usage increases to a percentage of 70% and even over 100% when I press the play button. Ableton live plays the sound back in various clicking and stuttering sounds which makes it impossible for me to continue working on my projects after a certain point, as everything plays back in slow motion and my sound is competely distorted.

I'm running Ableton through a Macbook Pro OS X core i5 2.4Ghz and 4G RAM which I bought just for Ableton. I'm looking for other ways that are not Freezing and the "RAM" button as these do not work out for me due to my specific project lay outs. I have also altered the Buffer size and this still does not allow my projects to play back smoothly.

I'm almost certain that the CPU overload begins when I add more samples and effects to my drum rack but I'm not sure how exactly to solve my problem I don not use an effect rack when adding effects and I use many effects on my drum samples from EQ's to Delay's sometimes having 4 to 5 efeects on one Drumrack sample.

 I was suprised when I worked with a producer which used a different DAW with a core i3 PC with 2G RAM and had even more complex projects than my own and he had no problems with his CPU usage.

If anyone experiences my problem on MAC and have resolved it please comment below, I'll appriciate it much.

    If you aren't sure which devices are eating up you CPU cycles, try grouping entire or sub-sets of devices and turning the group off then on again to see the effect on the CPU meter. This is especially helpful when you want to determining if only a few of your drum rack sounds are really taxing your machine.

    Another option is to Automate the On/Off button of a plugin so it's only on when needed. This will typically save a lot of CPU in a song and is dead-simple to do. 

    However, it does seem like something is odd about what you're running into. I am still using my 2009 Core 2 Duo 2.93Ghz Mac Book Pro and it still holds up fine. The only plugins that give me a hard time, if using them in quantity, would be Native Instruments.

    Try using the drum rack's option for send effects. Click the chain list and below the list of drum or other samples in the rack, should be space that says add effects here. You may have to click show return effects to show this window. Add your effects and then set the send levels for each of the effects on your various drum rack samples. 

    By doing this, you can conserve a good deal of CPU simply by sharing the processing load by using a single effect to process multiple sample sources.

    If this is a specific rack you are using for live performance as well as studio stuff, I would make a new version of it without the FX. Just resample the FX onto new audio clips and drag it into a new drum rack. (perhaps copy the old rack, delete the fx, and drag the new samples into it so volume, pans are not changed). This should give a pretty good approximation of your original rack and use much less CPU power. A drum rack is really just a bunch of simplers and these are fairly light on CPU. The problem comes with add a bunch of FX. The more FX you can eliminate by grouping, resampling, and using sends, the more efficient your sets will become for both in the studio and on the stage.

    I would suggest using the FREEZE feature in Ableton for each track - the more tracks you have rendering in real time will affect the CPU drain. So, Freeze the each track and that should free up your CPU power, making it easier to record the new ones ;)

    RIGHT CLICK at the top of the TRACK ( and left click Freeze Track

    Hope this helps you ..

    Best wishes
