Ron,
I have 512 channels in my profile. I use 64 channels for my lights and Channels 511 and 512 for my beat tracks. I change the order of my channels so that I have a beat track after channel 12 and a beat track after channel 40.
You could have as many beat tracks as you want, just use channels that are not being used by the controllers.
When I get home, I can do a screen shot for you if you want.
John
