So I decided to get an m-audio keystation and software piano lessons recently. Once everything arrived I realized that I can only play the keyboard through the learning software. M-audio is useless and Apple is being no help at all. I'd just like to practice with some sheet music and don't really need to record, but I can't seem to find the soft to do that. Please help. People have mentioned Garageband, but I really don't want to shell out cash for one program I already have and two I don't want to get the one that I may use.
