摘要： A set of formation data codes, which includes action event codes and duration codes, is loaded in an automatic player piano, and a controller interprets the action event codes for driving the solenoid-operated key actuators; since the solenoid-operated key actuators slowly push the associated keys, the hammers do not reach the strings, and any piano tone is not produced; the plungers make the keys sunk to different depth so that the keys are laid on a artistic pattern; the controller sequentially changes the artistic pattern, and offers an artistic visual expression to the audience.

摘要： An automatic player piano is equipped with a preliminary data producer comprising an experimental routine and an editor; a motion controller forces each of the black and white keys to travel on a test trajectory at different values of key velocity so that the black or white key gives rise to rotation of hammer by means of an action unit, and a hammer sensor varies the magnitude of a hammer position signal depending upon the current hammer position; the hammer velocity is converted to a value of MIDI velocity so that a table producer correlates the values of key velocity with the values of MIDI velocity; while an automatic player is performing a music passage, the motion controller exactly determines a value of key velocity on the basis of the relation already determined by the preliminary data producer.

摘要： An automatic player piano is equipped with solenoid-operated pedal actuators for driving the pedals in a playback; since a large quantity of induction is coupled to the solenoid, the driving signal is delayed due to long time constant so that the pedals behave differently from those in the original performance; a controller, which is incorporated in the automatic player, firstly determines a target mean current of the driving signal to be theoretically required for the reproduction of the pedal motion, and a temporary means current twice as much as the target mean current at the maximum; the controller supplies the driving signal at the temporary mean current to the solenoid in an early stage of each cycle, and, thereafter, recovers the driving signal to the target mean current so that the pedal motion becomes close to that in the original performance.

摘要： An automatic player piano includes keys driven for the angular motion through a hybrid feedback control loop; a controller, a key position sensor, a plunger velocity sensor and a solenoid-operated key actuator form parts of the hybrid feedback control loop for each key, and a current key position and a plunger velocity are reported to the controller; the controller determines a series of target position or a reference trajectory and a target velocity, and periodically compares a composite current position and a composite current velocity, which are determined on the basis of the current key position and current plunger velocity, with the target position and target velocity to see whether or not the key travels on the reference trajectory; if the answer is negative, the controller adjusts the driving signal to a proper duty ratio so as to force the key to travel on the reference trajectory.
