New Tracks for Overlapped Regions
Separate overlapped regions onto new tracks using the same channel strip. This allows you to see and work with information that is hidden.
As I think about it tracks basically contain instructions for sending output to a channel. The documentation considers using a drum machine — multiple, different sounds, and tracks for programming the machine.
I would use multiple tracks per channel for my software instruments EZdrummer, Miroslav Philharmonik, and SampleTank.
New tracks are created for wholly or partly overlapped regions, which are redistributed across the newly created tracks. A new track is created for each overlap. All tracks use the same channel strip as the original track. In other words, only one channel strip is used for all tracks.
