摘要： A performance operator control apparatus adapted to a player piano comprises a motion control unit and a key drive unit comprising a plurality of key I/O control ICs in connection with keys of a keyboard, which are driven by solenoids so as to realize automatic performance, wherein upon detection of electrification abnormality of solenoids or temperature abnormality, LEDs are turned on to indicate the abnormality. The key I/O control ICs receive velocity signals regarding the solenoids so as to perform feedback controls on the keys in the automatic performance. In addition, unoccupied channels of the key I/O control ICs, which are not assigned to the keys and sensors, are used to input monitoring signals and to output inspection signals. Herein, the abnormality is determined based on the difference between pre-inspection data and post-inspection data, which are transferred using a loop connection channel of the key I/O control IC.

摘要： While a player is fingering a music tune on a piano, an electronic assistant system monitors the keys to see whether or not the player starts to produce tones through a particular playing technique such as repetition; when the electronic assistant system finds particular key movements unique to the particular playing technique in an early stage, the electronic assistant system decides that the player intends to produce the tone through the particular playing technique, and forces the key to travel on a reference key trajectory in the later stage, whereby the player learns the particular playing technique.

摘要： An automatic player piano is a combination between an acoustic piano and an electronic system serving as a recorder and an automatic player; while a user is fingering a piece of music on the acoustic piano, the player strongly depresses some keys and softly depresses other keys so as to give artistic expression to the tones, and the depressed keys give rise to hammer motion at different values of hammer velocity; since the hammer velocity is proportional to the loudness of tones, the controller is expected exactly to determine the hammer velocity; the hammers travel on linear trajectories and parabolic trajectories depending upon the hammer velocity so that the controller estimates the hammer velocity by using different methods, whereby the controller can produce music data codes exactly expressing the tones to be produced.
