It's a piano! And it's playable! D/S move the left hand up/down an octave L/K move the right hand up/down an octave T/F move the left hand up/down a white key J/Y move the right hand up/down a white key Look at the back of the sheet music for where to put your fingers on the keyboard. I'm currently working on getting it to sound right, so bear with me. This may or may not ever happen :( Update: My new place, Keyboard v1.0 has an updated piano with better controls and sounds.
