摘要： An acoustic effect impartment apparatus detects striking of any one of strings by a corresponding hammer in an acoustic piano like a grand piano, and vibrates a vibration section with a driving waveform signal obtained by synthesizing sine wave signals of the fundamental frequency and harmonic frequency of the hammer-struck string. Such vibration of the vibration section is transmitted to the keys via a soundboard and bridge of the piano. Thus, vibration is excited in the hammer-struck string by the striking with the hammer but also by the driving waveform signal, so that an acoustic effect corresponding to the driving waveform signal is imparted. Because the driving waveform signal is a simple signal using the sine wave signals corresponding to the fundamental frequency of the string, a natural feeling of the acoustic piano will not be lost even when the acoustic effect is imparted.
摘要翻译：声学效果隔离装置通过在诸如钢琴的钢琴中的相应的锤子来检测琴弦中的任何一个，并通过合成基频的正弦波信号和基频的正弦波信号而获得的驱动波形信号振动振动部分锤击字符串。振动部分的这种振动通过钢琴的音板和桥梁传递到键。因此，通过用锤击而且通过驱动波形信号在锤击串中激发振动，从而赋予对应于驱动波形信号的声学效果。由于驱动波形信号是使用与弦的基频相对应的正弦波信号的简单信号，所以即使赋予声学效果，也不会失去原声钢琴的自然感。

摘要： A synchronous player system is used for recording an ensemble between an automatic player piano and an audio player and playback therebetween; while a user is playing on the automatic player piano in ensemble with the audio player, reference characteristic data of the performance is extracted from the audio music data, and are stored in a memory together with the event codes; when the user instructs the synchronous player system to reproduce the performance in ensemble with the same piece of music recorded in another compact disc, the synchronous player system extracts objective characteristic data from the audio data recorded in the other compact disc, finds differences through a correlation analysis, by way of example, and rescheduling the timing to reproduce the note events for synchronously controlling the automatic player piano and audio player.

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： A sound control apparatus for a keyboard-based musical instrument for avoiding a touch of a shutter to a back check, thereby appropriately setting a sound generation timing and maintaining a satisfactory touch feeling. The sound control apparatus comprises a shutter integrated with a hammer adapted to swing associated with a swinging motion of a key, extending along a plane including a path along which said hammer swings, and formed with a cutout in an edge on an opposite side to a direction in which said hammer swings. An optical sensor has a light emitter disposed on one side of the swinging path of said shutter for emitting light, and a light receiver disposed on the other side of the swinging path for receiving the light from said light emitter, and generates a detection signal in accordance with a light receiving state of said light receiver. A CPU sets a sound generation timing at which music sound should be generated based on the detection signal of said optical sensor responsive to opening and closing of a light path of the light from said light emitter of said optical sensor by said shutter, when said hammer swings.

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.

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.
