I am a musician but I can see how this is useful given much practice and a creative, well practiced ear. One can, and people have, make music out of much less inspiring media. I agree that the piano and sine sounds utilized leave much to be desired. I can, rather, see this driving well crafted, masses of sound that can be later arranged by in logic or protools. You don't have to sound like a machine ( though you are certainly free to, and there is nothing wrong with it.) It might require hacking, but that is usually required for anything new, music included.
