  • System and method for driving actuators in a reproducing piano
    Patent number: 7847168
    Abstract: A method and system for controlling actuators in a mechanical reproducing piano or other instrument. In one implementation, a single finite state machine is provided to control all the actuators. The finite state machine may be or include a shift register or a toggle register, which increases the operating speed. When a note is to be played, the desired dynamic is mapped into a start vector and a stop vector. The actuator is turned on when the state of the finite state machine is equal to the start vector, and is turned off when the state of the finite state machine is equal to the stop vector. Furthermore, the period of the finite state machine is adjusted to be directly proportional to the supply voltage. This allows notes to be played at the desired dynamics even when the supply voltage fluctuates.
