An electronic musical instrument having a manipulator which includes a hand manipulator and manipulation region capable of setting a reference point and/or reference axis, adapted for generating the musical tones of a rubbed string instrument. The distance from the reference point to the position of performance manipulation and/or the angle between the line connecting the reference point with position of performance manipulation and the reference axis may be calculated to produce parameters for controlling the musical tone signal, such as the bow pressure and the direction of the bow movement. |

DETAILED DESCRIPTION An object of this invention is to provide an electronic musical instrument capable of forming parameters for controlling the musical sounds by novel performance manipulation.
Another object of this invention is to provide an electronic musical instrument capable of enhancing the generation of musical sounds rich in expression of the rubbed string instrument.
According to an aspect of this invention, there is provided an electronic musical instrument comprising, manipulation means for achieving performance manipulation therein, having a manipulation region of at least two dimensions, and being capable of setting a reference point in the manipulation region, means for detecting a distance from said reference point to a position of performance manipulation, and means for generating a tone signal, capable of generating a tone signal using said distance from the reference point as a parameter of controlling the tone signal.
Further, there is provided an electronic musical instrument as mentioned above, further comprising, means for detecting a speed of said performance manipulation from time variation of the position of performance manipulation in said manipulation region, wherein said tone signal generating means is capable of generating a tone signal utilizing the speed of the performance manipulation and the distance from the reference point.
Further, there is provided an electronic musical instrument as mentioned above, further comprising means for generating a pressure signal based on said distance from the reference point, and said tone signal generating means is capable of generating a tone signal using the speed and the pressure as parameters for controlling the signal.
Also, there is provided an electronic musical instrument comprising, manipulation means for achieving performance manipulation therein, having a manipulation region of at least two dimensions, and being capable of setting a reference point and one axis including said reference point as origin in the manipulation region, means for detecting a distance from said reference point to a position of performance manipulation, means for detecting time variation of an angle formed between the direction connecting the position of performance manipulation and the origin and said axis, means for generating a tone signal, capable of generating a tone signal using said distance from the reference point and said angle as parameters of controlling the tone signal
