So, to answer the question, all the tracks loop together. I just built out the tracks to something like a half hour long. Yes, they initially vary in length. With the software you can select all the items in a track and lengthen or shorten them (have them play faster or slower). This way the track lenths can be matched. The slight change change in pace lost over the half hour or more of an individual track is not noticed, especially with the type of audio most of us use.
