    • A tone signal controlling apparatus for an electronic musical instrument comprising a body having a string corresponding portion, a movable performance member, and a sensor for detecting the action of the movable performance member with respect to the string corresponding portion, and generating a musical tone signal simulating a rubbed string instrument. The apparatus can control an electric signal simulating vibration of a string without any actual vibration of the string according the action of the movable performance member based on the output of the sensor, especially, by using signals representing a bow speed and a bow pressure which are applied to the string corresponding portion. Such special effects as vibrato can also be easily generated electrically. Owing to such electronic operability, the apparatus can also easily control the generation of the signal in accordance with a skill of a player.
    • 一种用于电子乐器的音调信号控制装置,包括具有弦对应部分的主体,可移动演奏构件和用于检测可移动演奏构件相对于琴弦对应部分的动作的传感器,并且产生乐音信号 模拟一个摩擦弦乐器。 该装置可以根据传感器的输出,特别是通过使用表示弓速度和弓形压力的信号来控制模拟弦的振动的电信号,而不会根据可移动性能部件的作用而产生弦的任何实际振动, 应用于字符串对应部分。 颤音的这种特殊效果也可以容易地电生成。 由于这种电子可操作性,装置还可以根据玩家的技巧容易地控制信号的产生。

    • A method of and apparatus for teaching and learning the production of good tone in bowing a stringed instrument uses electrical signals corresponding to position and velocity of a bow, bow pressure on the strings and sounding point. The signals are converted from analog electrical signals to digital electrical signals and taken to a computer which processes them for display and storage. Use of the computer and a monitor permits real-time display for instant evaluation of bowing technique by a student or teacher, and the possibility of storing the digital information and replaying it at any time allows the comparison of different performances by the student and also the study of results obtained by a teacher or a master performer and the comparison of these results with those obtained by the student.
    • 用于教导和学习在弦乐器中产生良好音调的方法和装置使用对应于弓的位置和速度,琴弦和探测点的弓压力的电信号。 信号从模拟电信号转换为数字电信号,并被送到处理它们以进行显示和存储的计算机。 使用计算机和显示器可以实时显示学生或老师的弓形技术的即时评估,并且随时存储数字信息和重播的可能性允许学生对不同的表现进行比较,而且 研究由老师或硕士表演者获得的结果,以及这些结果与学生获得的结果的比较。
