ABSTRACT:
A piano pedal activator assembly 12 is provided for actuating a sustaining pedal 14 of a piano 10. The piano pedal activator assembly 12 includes a reversible motor 28 including a shaft 30. A control circuit 62 is provided to activate the motor 28 and rotate the shaft 30. A pedal actuating lever 46 is coupled to shaft 30 through a worm gear assembly 32. Upon activation of the motor 28 to rotate the shaft 30 in one direction the worm gear assembly 32 causes the pedal actuating lever 46 to move downwardly to displace the sustaining pedal 14. When the motor 28 is actuated to turn the shaft 30 in the reverse direction the worm gear assembly 32 causes the pedal actuating lever 46 to move upwardly to release the sustaining pedal 14.
