Jakob,
Are you saying that beucause you bought the "audiophile" pakage that has the .wav format, the software runs slower???? This is one of the concerns I had about the size of this software on a laptop/PC??

Also(This is for Everone's comments and opinions):

Can anyone help me understand in simple terms how easy/difficult it is to create a backing track from an mp3 song. For instance I'm trying to learn "Hideaway" by Freddie king and I want to create a backing track so I can play to it

Thank you everyrone for your great advice!!
