Claims (1)

[Claims for Utility Model Registration] (1) Detecting the state of picking operation for at least one string at a plurality of fret operation positions, and specifying pitch designation information that designates a specific pitch and the timing at which musical tones are produced. a playing information output means for outputting playing information including string trigger information; a demonstration playing mode setting means for setting a demonstration playing mode for automatically playing a demo piece; and a demo playing mode setting means for setting the demo playing mode. a demo song setting means for selecting and setting an arbitrary demo song from the demo songs according to the playing information output from the playing information outputting means under the condition that the playing mode is set; and demo performance start means for starting automatic performance of the demo piece set by the demo piece setting means in accordance with the playing information while the demo piece setting means is set. A distinctive electronic stringed instrument. (2) The demo song setting means selects and sets the demo song based on the fret number obtained by detecting the fret operation position and the string number of the string on which the picking operation is performed. The electronic stringed instrument according to claim 1, characterized in that: (3) The demo song setting means selects and sets the demo song based on the string number of the string on which the picking operation has been performed.
The electronic stringed instrument described. (4) The electronic stringed instrument according to claim 1, wherein the demo song setting means is for selecting and setting a demo song based on a fret number obtained by detecting the fret operation position. (5) The electronic stringed instrument according to claim 1, wherein the demonstration performance starting means starts automatic performance of the demo piece when the picking operation is started. (6) The electronic stringed instrument according to claim 1, wherein the demonstration performance starting means starts automatic performance of the demo piece when the fret operation is started. (7) The electronic device according to claim 1, further comprising demo performance stopping means for stopping the automatic performance of the demo song if a re-picking operation on the strings is detected during the automatic performance of the demo song. stringed instruments. (8) The plucking information output means indicates that a picking operation is performed on the string while the fret operation position is in an open string state while the demo performance mode is set by the demo performance mode setting means. 2. The electronic stringed musical instrument according to claim 1, further comprising demo song setting prohibition means for instructing said demo song setting means to prohibit selection and setting of a demo song when detected. (9) When the playing information outputting means detects that a picking operation has been performed on at least two strings while the demonstration playing mode is set by the demonstration playing mode setting means, the 2. The electronic stringed instrument according to claim 1, further comprising demonstration performance start prohibition means for instructing the demonstration performance start means to prohibit the start of demonstration performance. (10) The playing information output means includes a string trigger sensing means for sensing the start of vibration of the string and obtaining the string trigger information, and sensing the fret operation position;
fret position sensing means for obtaining the pitch designation information, and the demo song selection setting means includes at least one of string trigger information from the string trigger sensing means and pitch designation information from the fret position sensing means. 2. The electronic stringed instrument according to claim 1, wherein the demo piece is set based on one of the pieces of information. (11) 11 The playing information output means includes a string vibration pickup device provided for each string, pitch extraction means for extracting fundamental frequency information of string vibration from a signal from the string vibration pickup device;
pitch designation information generation means for obtaining the pitch designation information based on the fundamental frequency information extracted by the pitch extraction means; the demo song setting means;
A fret operation position of a string that is generating string vibration is determined from the fundamental frequency information of the string vibration given by the pitch extraction means, and from the string number of this string and pitch designation information corresponding to the fret operation position. 2. The electronic stringed instrument according to claim 1, wherein a specific demo song is set. (12) 12 The fret position sensing means receives an echo generated when the ultrasonic wave propagated to the string is reflected at the fret operation position, and measures the echo reception time to detect the fret operation. 11. The electronic stringed instrument according to claim 10, wherein the pitch designation information is obtained by sensing a position.
