Automatic playing apparatus with pedal actuators supported by bracket independent of case of acoustic piano

An automatic playing apparatus associated with an acoustic piano having a plurality of keys each movable from a rest position to an end position for causing music strings to produce an acoustic sound, pedal mechanisms for imparting effects to said acoustic sound and a piano case for accommodating said plurality of keys and said pedal mechanisms, comprising:

• a) a key actuator unit having a plurality of solenoid-operated actuators respectively associated with said plurality of keys for moving the associated keys;
• b) a pedal actuator unit having a plurality of solenoid-operated actuators respectively associated with said pedal mechanisms for actuating the associated pedal mechanisms, wherein said pedal actuator unit is supported by a frame which is independent of said piano case so as to isolate said piano case from said pedal actuator unit during actuation of each of said pedal mechanisms;
• and
• c) a controller unit operative to produce drive pulse signals, and selectively supplying said drive pulse signals to said plurality of solenoid-operated actuators of said key actuator unit and said plurality of solenoid-operated actuators of said pedal actuator unit.
