Type stuff! No newline support, unfortunately. :'(

u/Jenky

Also no insert-style editing, only way to erase is backspace. Old-school terminal/console style. 😎

u/nonce

I love it that backspace works!

This is the strangest piano i've ever played, but good job!
u/Woodmouth

Also, i found a way to stop it, just press shift. (or any other key with a value too high or low to hear (At least i think that's what happens))

Check the old comments for some simple tunes to play. You'll need to click on the blank canvas for keyboard focus. Hit Space, Shift or Escape for "silence".
