If it sounds spot on then why change it ;)

you can compress the whole mix but you need to consider why you are compressing the mix in the first place, it is to compress the dynamic range of the track ie squashing togeather the loudest bits and the quietest bits so that you can increase the overall level of the track. so what you are essentially doing is makeing the quietest bit of the track... louder whikst keeping the loudest bit of the track at the same volume.

The best way is to have a rough idea of what your are trying to do and then play around, but the smallest setting change can have a big efect on the track. :lol: :lol: hope this helps
