Claims

[Claims for Utility Model Registration] (1) When at least one stretched string is pressed and the corresponding string is played or rubbed, the In an electronic stringed instrument, a musical sound of a pitch corresponding to a fret position specified by a pressing operation is generated from a musical sound generating means at the timing of the string-pulling operation or string-rubbing operation, and a sound effect such as a stringing sound or a noise sound is generated. a sound effect generating means for generating a sound effect so as to generate the sound effect when the position of the pressing operation is moved from a fret position specified by the pressing operation on the string toward another fret position; An electronic stringed instrument characterized by comprising: sound effect generation control means for instructing the generation means; (2) The sound effect control means instructs the sound effect generating means to generate different types of sound effects in accordance with the speed of movement of the fret position when the position of the pressing operation is moved. The electronic stringed instrument according to claim 1, characterized in that: (3) The sound effect generation control means controls the sound effect generation means to generate the sound effect only when a musical tone corresponding to the pressing operation is being generated by the string plucking operation or the string rubbing operation. 3. The electronic stringed instrument according to claim 2, wherein instructions are given to the electronic stringed instrument. (4) The sound effect generation control means causes the sound effect generation means to generate a sound effect so that the sound effect is generated when the position of the pressing operation is changed from a predetermined fret position to another fret position. 4. A frequency change instruction is also given to the musical tone generating means to change the pitch of the musical tone to be generated to a pitch corresponding to a destination fret position. electronic stringed instrument. (5) further comprising timbre selection means for selecting the timbre of the musical sound to be produced by the musical sound generating means;
The sound effect generation control means instructs the sound effect generation means to generate the sound effect according to the type of tone of the musical tone selected by the tone selection means. The electronic stringed instrument according to claim 3 or 4.
