摘要： A brand-new player piano is designed to have a compatibility with the conventional player piano and the electronic musical instrument based on the MIDI standard while providing a capability of playing a highly skilled music performance such as the performance technique of half stroke. The player piano creates a new version of performance information which uses a key-depression event frame in addition to a string-striking event frame and a key-release event frame. Herein, the string-striking event frame contains extensional information for a string-striking velocity, while the key-release event frame contains extensional information for a key-release velocity. The extensional information is not specifically defined by the MIDI standard and is neglected by the conventional player piano. The key-depression event frame, which is newly introduced by this player piano and is neglected by the conventional player piano, represents a note number and a key-depression velocity as well as extensional information for the key-depression velocity. Using the extensional information, it is possible to control each of the velocities more precisely. The performance information is recorded on a recording media. At a reproduction, the player piano produces trajectory data and position data with respect to each of the keys on the basis of the performance information. The trajectory data represent a key-depression-uniform-motion trajectory and a key-depression-slow-down trajectory along which a key moves when being depressed. The trajectory data also represent a key-release-uniform-motion trajectory and a key-release-slow-up trajectory along which the key moves when being released.
摘要翻译：全新的演奏器钢琴被设计为与传统的演奏者钢琴和基于MIDI标准的电子乐器兼容，同时具有演奏高度熟练的音乐表演的能力，例如半冲程的表演技术。播放器钢琴创建一个新版本的演奏信息，除了打字事件帧和按键释放事件帧之外，还会使用按键抑制事件帧。这里，串击事件帧包含用于串击速度的延伸信息，而密钥释放事件帧包含用于密钥释放速度的延伸信息。扩展信息没有由MIDI标准具体定义，并被传统的演奏者钢琴忽略。由该演奏者钢琴新引入并被传统演奏者钢琴忽略的按键抑制事件框架表示琴键数和按键速度以及按键速度的拉伸信息。使用延伸信息，可以更精确地控制每个速度。演奏信息被记录在记录媒体上。在再现时，演奏者钢琴根据演奏信息产生关于每个琴键的轨迹数据和位置数据。轨迹数据表示按键移动的按键均匀运动轨迹和按键减速轨迹。轨迹数据也表示键释放均匀运动轨迹和按键释放缓慢轨迹，当键被释放时，键移动。

摘要： An automatic player piano has a released key velocity estimator for modifying the constant released key velocity of a piece of music data information to a target released key velocity; a memory stores relation between the target key velocity estimator and other key-touch factors such as a final hammer velocity and a time interval between an impact timing and a key release timing, the released key velocity estimator supplies the key-touch factors to the memory so as to read out the target key velocity estimator, and modifies the piece of music data information so as to indicate the target released key velocity.

摘要： An automatic player piano prolongs acoustic sounds in playback as if a player pushes down a sostenuto pedal, and a controller is responsive to a first piece of music data information representative of key-on state, a second piece of music data information representative of key-off state, a third piece of music data information representative of pedal-on state and a fourth piece of music data information representative of pedal-off state so as to play a tune by using key actuators associated with the keys; when the first piece of music data information is supplied to the controller for a key, the controller instructs the key actuators to change associated the key from the key-off state to the key-on state; when the second piece of music data information is supplied to the controller without the third piece of music data information for a key, the controller instructs the key actuator to change the key from the key-on state to the key-off state; when the second piece of music data information is supplied to the controller in the presence of the third piece of music data information for a key, the controller instructs the key actuator to maintain the key in the key-on state; when the fourth piece of music data information is supplied to the controller after receipt of the second piece of music data information, the controller instructs the key actuator to change the key from the key-on state to the key-off state.

摘要： A solenoid driving apparatus for actuating keys of a player piano is provided in which respective key striking strength data can be applied to respective solenoids of keys, so that musical tones can be reproduced correctly and in which the key striking strength data at the time of musical performance can be compensated for high fidelity reproduction. The solenoid driving apparatus includes a plurality of keys and solenoids provided on each key. When a key is depressed, a first key striking strength data corresponding to key striking strength and a data designating the depressed key are generated. The first key striking strength data is then converted into a second key striking strength data so as to make the latter data in linear proportion to an operating or response speed of the solenoid. In accordance with the second key striking strength data, a solenoid driving data is generated, and is applied to the solenoid corresponding to the key designated by the designating data. The solenoid driving data thus converted from the second key striking strength data causes musical tones to be reproduced as having correct timings and high fidelity.
