If your Live session is making your computer grunt & groan under the workload, then this article from Joshua Casper is for you. Here's a multitude of ways to cut back on the CPU load in Ableton Live.  

Reduce the Sample Rate of Live

Make use of the Freeze function

PRO TIP: I like to freeze the device laden channel and create a new audio channel below it. Then you can click the frozen channel and drag the audio file into the new audio channel. After which I deactivate the frozen channel, but keep it in case I ever need to go back, unfreeze and make changes.

The freeze and eq tips are solid, but the rest is basically just lowering your quality. The beats warp mode works for beats, but adds a lot of artifacts to melodies and textures.

If you have to use all of these to get your workflow on, I'd rather work destructively, bouncing or freeing hi-quality audio, before starting the next resource consuming task. Nobody wants low quality audio, right?

That's what the tip says. Use beats mode "when possible". If it isn't possible bounce (resample) the audio using Complex Pro (or which ever other warp mode at the desired BPM) then re-import to use beats mode, or even better yet no warp mode.

These tips are for people that need to do things like this so their computers don't fry or freeze. I used to have to do all of these to some degree or another before I got me new machine.

What I like to do with a frozen midi/audio clip as mentioned above is create the audio track but instead of just dragging the part on to the new audio track.Hold Ctrl & copy it on to the new track.This way you can keep any work you have done intact until you are completely happy with it & then get rid of it.
