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： In an APDCM decoding circuit, an adaptive inverse quantizer which forms a quantized coded signal, produces a residual signal and upper and lower limits thereof. An adaptive prediction circuit uses the residual signal to predict a quantization, which is added to the other signals. The added residual is converted into a nonlinear encoded PCM for output. However the output is PCM linearized and compared to the added upper and lower limits to determine if the output should be incremented or decremented.

摘要： An optical transducer includes a photo-electric converter supported by a shank flange rail and optical modulators respectively attached to hammers of an automatic player piano; since a neck portion makes a photo-modulating pattern closer to the rotational axis of each hammer than a boss portion adhered to the side surface of the hammer shank, the photo-modulating pattern is rotated in a narrow space in the vicinity of the rotational axis so as to permit the photo-electric converter to monitor the hammer motion between the rest position and the end position without any interference with other component parts, and the boss portion is easily adhered to the side surface under the condition that a worker lifts the hammer over the adjacent hammers.
