Abstract
An automatic player piano is implemented by a combination of an acoustic piano and an automatic playing system, and a velocity feedback loop and an acceleration feedback loop control solenoid-operated key actuator units for reproducing a performance so that the acceleration feedback loop cancels the undesirable increment of the resistances of the solenoid coils and aged deterioration.
