I also found these tutorials most helpful. I was going through TNT withdrawal, and Lessons 29 and 30 filled that void for me. I wouldn't have thought of flexing an apple loop like that, and I am downloading Jordan Rudess' "Notes on a Dream" right now. I really enjoy his music, and will get more in the future, so thanks for introducing his great music in these perfectly sequenced tutorials. Now I'm off to experiment!
