I often work on projects where I am given a stereo file with a reference vocal on one side and a guitar or piano on the other. This custom action will split the track containing the imported stereo media into two separate mono tracks making it possible to adjust each one separately. The action does the following: 1. Duplicates the track. 2. Selects the item on the first track. 3. Sets the item take to channel left. 4. Selects the item on the next track. 5. Sets the item take to right channel. Of course the tracks do need to be named appropriately, but at least for me, this is a handy little macro.
