Right when mixing down heavy projects...not when tracking a VO. And anyways who cares if it makes some noise when mixing down?!?
I got a Macbook Pro with a quad i7 core, 2.4ghz and 8gb of ram, refurbished from the apple site...saved 500$ and it works so well!
I mixed this way back...like 3 years ago. I tried my hand in mastering.... why not have some fun :p I kind went crazy with my plugins:D:D:D

Am I crazy or does...
Even though you have compressors on the tracks, they are not doing anything. You should learn how to set them properly, and what they do. It does sound like a cool track though.
