External keyboard support is great
Ive been meaning to sit at my keyboard and properly re-learn the notation but none of the other apps supported that and I really hate those little on-screen buttons. With the latest piano tutor I can finally do it. Im really happy, I like this method of learning, its how Ive learned to touch type as well, definitely a worthwhile app. Admittedly the interface is a bit clunky and looks like a late 90s application for a pc, but otherwise definitely worth the price.
