Show Hidden Tracks

I'm using Music Creator 6 Touch. I accidentally pressed or clicked something while selecting a track in the track view that hid all of the other tracks. They aren't deleted because they are still visible in the console view and I still hear them when I press play. However, I can no longer view them or edit them in the track view. Obviously, this is a major problem. How do I fix this so that I can see and edit the tracks again? Thanks in advance for any help you have to offer.
