You use the letters on the keyboard, not clcik on it. I worked really hard on this. probaly one of my best projects. It took forever to make the piano zoom in 'cause i had to do stop animation. Please "love it" and i'll add more octaves to it. Please take a vote on it though. Should I make 3 octaves, with no black keys (type in 3),or should I make 2 ocaves with one octave of black keys (2)?
