Here is a pretty sweet way of getting individual tracks to pump in your session. This is a much better way than using side chain compression because it allows you to dial in how much pumping you would like to add per track. It also seems to be much easier to get everything working just right when you dial in the settings with an expander instead of a compressor. On top of all of this, it opens up a lot more doors for more creative possibilities.
