Yeah I agree, just start doing the simple things and every track you do you'll learn that little bit more.
Thats what ive been doing and slowly i'm learning.
I got hold of "Cubasis go 3.0" from PC World for 15 quid the other day. Its just like an easier version of Cubase but the best part is you get a nice big manual explaining everything and it all helps if you are using other versions of cubase, so you dont have to stir at the online ones for hours on end just to find out how to press play etc
