Record your tracks into audio within Live to get rid of all your loaded plugins, this'll have a massive effect on your CPU usage
...or just use the freeze function which'll essentially do the same thing but'll keep your effects there in case you need to go in and change something. Also negates the need to create additional audio tracks.
Yeah that works too, it has its ups and downs though. The problem with that however is that it doesn't allow you to freeze if you have sidechain on it, but it isn't necessarily so hard to work around I suppose.
True dat. But I don't think that should be a problem unless you're extensively using sidechaining for everything
I tend to sidechain a little bit of everything to what ever when I want something to hit every once and a while and come through the mix. I think I just made the habit of using audio tracks to for example record several synth effects to audio tracks so I don't end up with 20 midi tracks with powerful synths on them.
