Abstract
A servo-controlling system incorporated in an automatic player piano selects detecting signals each indicative of actual status of a key or a pedal to be manipulated from all of the detecting signals, and sequentially fetches the selected detecting signals in a time sharing fashion for comparing the selected detecting signals with reference signals each indicative of target status of the key or the pedal, thereby promptly controlling actuators associated with the keys and pedals to be manipulated without complex wiring network.
