Its pretty much finished except for some little cosmetic parts. I kinda don't like the button setting anymore, though...
Anyhow,
here you go. You use every letter key except L and every number key to play a different note and you can change the pitch for most instruments by holding down left or right.
Enjoy. There's not much to take a screenshot of. Its not a game, its like... a musical something.
