摘要： A hammer sensor of a keyboard musical instrument monitors a hammer action from a home position to a rebounding point on a stopper or strings, and a controller determines a hammer velocity and a time at an intermediate point on a trajectory of the hammer in a recording mode; the controller delays the time so as to determine a key-on timing, and an electronic system reproduce the acoustic or electronic sound at the key-on timing in a playback mode so as to reproduce the acoustic or electronic sound at the same timing as the original sound.

摘要： An automatic player piano has key sensors for producing digital key position signals representative of current key positions and a recording unit for producing pieces of music data information on the basis of the key motions; however, the key sensors have individualities, and vary the values of the digital key position signals in different ranges, respectively; the recording unit selects different components bits from each of the digital key position signal depending upon the value at a reference point so as to make the difference between the ranges small.

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： Keys, which are incorporated in an automatic player piano, are monitored with an optical transducer system. The optical transducer system includes sensor heads provided on both sides of the key trajectories, LEDs connected to predetermined sensor heads through optical fibers, LDDs connected to the other sensor heads through optical fibers and a controlling unit. A luminescence controller is connected to the LEDs for optimizing the luminescence, and bias controllers are respectively connected to the LDDs. The luminescence controller and bias controllers optimize the luminescence of emitted light and the bias level of electric signals so that the optical transducer system is free from the individuality of component parts and the deterioration.
