摘要： Automatic player pianos and internet form a music performance system for a music session on the automatic player pianos through data communication between the automatic player pianos, and a communication time lag and mechanical time lag are unavoidably introduced between the data transmission and the data reception and between the data reception and tone generation; one of or both of the time lags are compensated by employment of an electronic tone generation, presumption of key positions or presumption of key event so that the slave automatic player piano generates the tones almost concurrently with the tones generated through the master automatic player piano.

摘要： While an automatic player piano is reenacting a music tune, the automatic player piano sometimes fails to miss a tone or tones in a repetition due to a high-speed key movement; a controller searches a music data file for a series of key events expressing the repetition, and makes the key movements uniform without changing the lapse of time from the last key event before the repetition and the lapse of time to the first key event after the repetition so that the automatic player piano is less liable to miss a tone.

摘要： An electronic proof system is provided in association with an automatic player piano; while a human player is practicing a music tune on the acoustic piano, the electronic proof system monitors the pedals of piano to see whether or not the player brings the pedals to target pedal positions; if the current pedal position is spaced from the target pedal position, the electronic proof system gives rise to fine vibrations of the pedal, and makes the player notice the pedal staying at incorrect pedal position through the tactile impression.

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.

摘要： An electronic piano is controllable with a remote controller; since the remote controller is physically separated from the electronic piano, users are liable to mislay the remote controller somewhere around the electronic piano; in this situation, the user instructs the electronic piano to transmit a radio wave representative of inquiry, and the missing remote controller responds to the inquiry by transmitting a radio wave representative of annunciation; the electronic piano is equipped with antennas separated from each other on the piano cabinet, and the received power at the antennas is varied depending upon the location of the missing remote controller; the electronic piano analyzes the received power so as to notify the user of the possible location of the missing remote controller.

摘要： An automatic player piano has various sorts of individuality due to differences in size, design margins applied to the component parts and a difference in electric characteristics of system component parts so that key position signals contain error components due to those sorts of individuality; plural feedback control loops are created between the key sensors and key actuators, and the error components are eliminated from the current key positions through the normalization; even if an original performance is reenacted through the automatic player piano different from that used in the recording, the feedback control loops cause the key actuators to force the keys to move along reference trajectories determined on the basis of the music data codes, whereby the manufacturer makes the key sensors shared between the recording system and the automatic playing system.

摘要： An automatic player piano has a feedback control loop for each of the black/white keys; the controller firstly determines a reference trajectory, i.e., a target key position varied with time for each key to be moved in the play-back, and calculates a target key velocity, and compares a true key position reported from a key sensor and a true key velocity calculated from the true key position with the target key position and target key velocity for optimizing the duty ratio of the driving signal; the positional difference and the velocity difference are independently multiplied by a positional gain and a velocity gain so as to determine the optimum duty ratio; since the ratio of the velocity gain to the positional gain is 1 to 3, the key travels along the reference trajectory without oscillation and overshoot.

摘要： In order to precisely express motion of a key or motion of a hammer, a voice message for the polyphonic key pressure and another voice message for the control change, which stand idle in an automatic player piano, are used to express rough key position or rough hammer position and an offset from the rough key position or rough hammer position, and the offset is described at a high resolution on an ordinary trajectory between the rest position and the end position and at a low resolution outside of the ordinary trajectory; moreover, the numerical range expressed by the third byte of the voice message for the polyphonic key pressure is divided into two numerical sub-ranges respectively assigned to the keys and hammers so that only a few voice messages are required.
