摘要： A method for generating a music file for recording user performance may include: detecting, by a sensor, an event indicating a status change of an execution device of the keyboard instrument; generating, by the sensor, a signal corresponding to the detected event; receiving, by a processor, the signal; and generating, by the processor, a music file based on the signal. In some embodiments, the execution device may include a weight lever. The weight lever may a concrete structure in the keyboard instrument to simulate a rebound force generated by hammer striking on string, by striking on an elastic structure. In some embodiments, a rebound force for a first weight lever may be different from a rebound force for a second weight lever by adjusting parameters of the elastic structure or the weight lever.

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 keyboard for an electronic instrument and an electronic piano providing a key touch and a key touch response similar to those of an acoustic piano and stabilizing the key touch response for each key. Two detection positions of a key stroke are detected by a jack tail sensor or a jack sensor by detecting contact of a jack tail equivalent member or a jack equivalent member, before or after a hammer equivalent member disengages from or releases from a jack equivalent member. A time difference between the two positions is not adversely affected by the let-off of the jack equivalent member. Therefore, the positions and the time difference are detected stably for each key. Sound timing and sound intensity are controlled based upon the detected positions and time difference between the positions. Therefore, a key touch response, similar to that of an acoustic piano, can be stably obtained for each key.
摘要翻译：用于电子乐器的键盘和电子钢琴，提供与声学钢琴类似的按键触摸和按键触摸响应，并稳定每个键的按键触摸响应。钥匙行程的两个检测位置由千斤顶尾部传感器或千斤顶传感器通过在锤子等效构件脱离或从千斤顶当量构件释放之前或之后检测千斤顶等效构件或千斤顶当量构件的接触来检测。两个位置之间的时间差不会受到千斤顶等效构件的释放的不利影响。因此，针对每个键稳定地检测位置和时差。基于检测到的位置和位置之间的时间差来控制声音定时和声音强度。因此，可以稳定地获得与每个键相似的与原声钢琴相关的按键触摸响应。

摘要： In a piano mechanism, the sound volume can be effectively controlled without changing the feel of the key or tone quality. A hammer regulating button projecting from a hammer rail contacts the upper face of a catcher just before a hammer strikes a string. By restricting the string striking movement, the volume of string striking sound is controlled, irrespective of the mechanical operation of a jack or other associated transmitting components responsive to the key depressing. No cushioning material is required between hammer and string. In a piano having an electronic sound source built therein, even when the keys are depressed, the hammer can be stopped from striking strings by the provision of a hammer shank stop rail and a catcher regulating button. Therefore, without generating a string striking sound, sounds are generated from the electronic sound source. By manually turning an adjusting screw of the catcher regulating button, the position of the hammer when stopped can be adjusted. Therefore, even after repeated use, the string striking movement can be positively stopped.
摘要翻译：在钢琴机构中，可以有效地控制音量，而不改变琴键或音质的感觉。从锤子轨道突出的锤子调节按钮在锤子撞击绳子之前接触捕获器的上表面。通过限制弦线冲击运动，可以控制弦击音的音量，而不管千斤顶或其他相关联的发射部件的响应于按键的机械操作。锤和弦之间不需要缓冲材料。在其中内置有电子声源的钢琴中，即使按下按键，也可以通过设置琴槌止动轨和收音机调节按钮来将琴槌停止在击弦上。因此，不会产生串音冲击的声音，从电子声源产生声音。通过手动转动捕手调节按钮的调节螺丝，可以调节锤子在停止时的位置。因此，即使在重复使用之后，可以肯定地停止线条打击动作。
