摘要： Dampers provided in corresponding relation to a plurality of keys are each controlled in response to both an operation of a pedal and an operation of the corresponding key. One half region or half point is determined based on a plurality of half pedal regions or half pedal points, in a stroke of the pedal, specific to the individual dampers. Performance data instructing a pedal operation is generated and recorded on the basis of a stroke position detected in response to a pedal operation and the determined one half region or half point. For each of the keys, a key-damper half region or key-damper half point in a stroke of the key is identified in advance. Performance data instructing key operations is generated and recorded on the basis of the key-damper half regions or key-damper half points specific to the keys and stroke positions detected in response to key operations.

摘要： In a player piano, a position sensor is provided on an end portion of a lifting rail for detecting a vertical position of the lifting rail. In storing performance data of dampers, a signal output from the position sensor and indicative of a vertical position of the lifting rail is converted into a digital signal, and a position value indicative of the position of the lifting rail is generated on the basis of the digital signal and stored into a buffer. A conversion section converts the position value into a vertical position of a pedal rod connected to a damper pedal, and the thus-converted vertical position is converted, into a control value which a control change message of the damper pedal in MIDI-format data can take. The control value obtained in the aforementioned manner can be recorded into a recording medium as performance information.

摘要： In a musical instrument, such as a piano, having a sound board, the sound board vibrates in response to vibrations of a string responsive to depression of a key. A waveform corresponding to such vibrations of the sound board is detected and recorded into a memory for each of the keys. The recorded vibration waveform is usable for reproduction of a sound based on sound board vibrations. In a sound reproduction apparatus, such as a piano, having a sound board, an excitation device physically excitable in response to an input waveform is provided on the sound board. In response to an operation of a key, a sound board vibration waveform corresponding to the operated key is read out from the memory, and the excitation device is driven in accordance with the read-out waveform signal so that the sound board is vibrated.

摘要： A key depression (i.e., string striking) is performed while a pedal is kept at a set non-key-depressed-state corresponding position (a rest position of a hammer). A string striking velocity immediately before string striking and a string releasing velocity immediately after the string striking are detected, and a coefficient of rebound is calculated on the basis of the detected velocities and stored in association with the current value of the rest position of the hammer. Similar operations are repetitively performed with individual ones of different rest positions of the hammer, wherein each of the different rest positions of the hammer corresponding to each of a plurality of stroke positions within one stroke of the pedal. Thus, a distribution curve of the coefficients of rebound detected in association with the plurality of stroke positions is obtained and a half point of the pedal is identified based on the distribution curve.

摘要： An actuator includes a movable member that, when moving, abuts against a key (performance operator) to move the key. A first sensor detects motion of the key. A second sensor detects motion of the movable member. A processor determines, based on outputs of the sensors, whether or not the key and the movable member are currently in a mutually separated state. When the key and the movable member are in the mutually separated state, the processor controls the actuator in such a manner that the key and the movable member are in contact with each other. When the key and the movable member are not in the mutually separated state, the processor controls the actuator by use of feedback information based on the output of the first sensor, whereas, in the mutually separated state, the actuator is controlled by feedback information based on at least the second sensor output.

摘要： Each of Dampers provided for each of keys is controlled in response to both an operation of a damper pedal and an operation of the corresponding key. For each of the dampers and over one stroke of the pedal in at least one of depressing releasing directions of the pedal, load information indicative of loads imposed on a portion linked to the damper is acquired in association with individual stroke positions of the pedal. Then, for each of the dampers, a half pedal region is identified on the basis of relationship between the stroke positions and the loads corresponding to the stroke positions. The portion linked to the damper may be any suitable portion related to a damper lever moving in an up-down direction in interlocked relation to both of vertical movement of a lifting rail responsive to an operation of the pedal and an operation of the key.

摘要： A sound generation mechanism, provided with a string for generating a vibration sound in response to striking by a hammer, is automatically played in accordance with performance data. The performance data include striking data (note-on event data) for designating timing at which the string should be struck by the hammer, velocity data indicative of an intensity of the striking, and muting data (soft pedal data) for controlling muting. A controller determines drive start timing of the hammer in accordance with the velocity data in such a manner that the string is struck by the hammer at the timing designated by the striking data and performs control such that the drive start timing is advanced in accordance with the muting data. Thus, the string is struck at the striking timing designated by the striking data, but also muting control is performed in accordance with the muting data.

摘要： An elongated lifting rail is displaceable to collectively pivot a plurality of damper levers. An actuator is provided beside or underneath the lifting rail for automatically displacing the lifting rail. The lifting rail is displaced, in response to driving of the actuator, to displace the damper levers so that the dampers are moved away from contact with sounding members. Further, a position sensor is provided for detecting a displaced position of the lifting rail, so that position data detected by the position sensor is used for operating position control and/or operating position recording of the dampers.
