Signal lines X, Y, θ, and P in the figure indicate detection signals of the X position, Y position, rotation amount, and grip pressure of the operating rod 4, respectively.

Based on each detection signal, the microcomputer 24 performs predetermined arithmetic processing to produce bow speed signals a. Bow pressure signal b,
The pitch signal C and other parameters d such as the attenuation coefficient are calculated and input to the sound source 27. A physical sound is synthesized within the sound source 27 based on each parameter controlled by the operation of the performance operator 22, and this synthesized sound is outputted from the sound system 28 as a performance sound of a bowed string instrument such as a violin.

It is possible to input control signals simultaneously, which improves the operability and sense of use of input operations. In addition, if used as an input device for controlling the musical tone parameters of an electronic musical instrument, it can be used as a performance operator compatible with the bow of a stringed instrument in addition to a keyboard, so it can provide a playing feeling similar to that of an actual stringed instrument. It is possible to detect each performance function (movement) of the performance controller, create parameters corresponding to the string and bow string movements of a bowed stringed instrument, and input them to the sound source, resulting in synthesis that approximates the sound played by an actual bowed stringed instrument. You can create sounds.
