That program actually sounds (no pun intended) pretty good. Let me know how you get on if you buy it :)
As for music theory, I dont know alot about it really except that its very deep and complicated. I scratched the surface when I was doing my BTEC, but it was literally only a two hour tour about different musical scales that are used around the world.
Funnily though (you might like this) I remember Paul telling us there was a musical note that was banned in the middle ages (cant remember which one) nick-named the "devils note", and if someone played it they would be executed for blasphemy or something. Harsh :lol:
