Abstract
A vibrato assembly for a keyboard percussion instrument comprises a motor and a vibrato fan or disc assembly. A motor () is responsive to a controller (), a run/stop switch (), and a potentiometer (). Pulleys (A,B',) and a timing belt () couple rotation of the motor to an assembly of resonator or vibrato fans () via one or more magnets () or magnetically susceptible members to isolate vibrations. A sensor is activated by one of the magnets to sense the rotational position of a pulley when the fans are oriented vertically. When a run/stop switchis in a 'stop' condition, sensorsignals controllerto stop the motor, thereby leaving the fans vertical so that resonant tubes () are in an open condition when the vibrato function is stopped.
