This piano was sitting unused in our living room for the better part of a decade, so I decided to give it a new lease of life recently by fixing some of the sticking keys, recalibrating the old PianoDisc system from the 1990s, and updating the system to be able to play Midi files. Guy restores an unused kohler and Campbell piano to play by itself. The piano plays the attack on titan anime song. The keys press down on its own.
