Well, it's hard at first, but I'd by lying if I said anyone could make something good from scratch. There are a lot of preset beats, but eventually when you play with them alot, all your songs start to sound the same. Once you master the piano roll, and editing sounds (echos, sound time, cutting, beats, etc..), the only thing left is your musical ear and the ability to make it all flow together. It's confusing at first, but if you look around for help sites to get you started, it comes naturally.
