Today myself and Lee looked at one of my sketches for my EP. I exported all the stems into Pro Tools  and used a frequency analyzer plugin to remove the low end and other frequencies from each instrument. This allowed me to give each instrument in the mix a place to sit.

When I enter the mastering stage, I can effectively turn up the levels of the mix without it suffering distortion. For next week I will bring Lee another sketch and we will apply the same techniques to it.
