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".
