I assume it's on another gadget. Check the connection to the computer, try swapping keyboards. If the problem is inside the grand piano it may be as simple as some contamination on the circuit board or a faulty nouns. Keyboards are pretty simple, you might want to disassemble it and look for anything out of place.
if you rebooted and it still exists, try a different grand piano.
Alt+Shift I think.
restart, or try taking it apart and cleaning it out, but be VERY wary
