Here's a short tracks demo.  It's not meant to be a tutorial but instead introduces one way tracks can be used.

This is a fake sequence I created using the tapper in a few minutes, so the sequence is rough.  I did the whole video in one shot ad lib, so it's not perfectly organized and the sound quality isn't great.  All in all, it didn't turn out too bad.  Here are few notes on tracks:

• Each track must contain at least one channel, but it could contain any number of channels or even all your channels.  For this demo, all of my channels are in all of the tracks. 
• Each track has unique grid timing in this demo.  Note that you can have identical timing on each track if desired. 
• There are many different ways to use and organize tracks.  This demo illustrates one possible use.  

I submitted the original video on the LOR forums, and the initial copy had several issues that have since been corrected.  If you'd like to view the original post, please visit http://lightorama.mywowbb.com/forum72/16194.html.  You might some other helpful hints and tips there too.
