Claims (1)

[Scope of Claim for Utility Model Registration] 1. An electronic stringed instrument that detects the plucking operation on the strings stretched on the instrument body and generates a musical sound from a musical sound generating means with a pitch corresponding to the fretting position of each string, a pitch data setting means for detecting the fret operation position of each string and setting pitch data corresponding to the fret operation position of each string; an external operator; and an external operator state detector for detecting the operating state of the external operator. and determining a change in the operating state of the external operator based on the detection result of the external operator state detecting means, and determining whether a musical tone is generated from the musical tone generating means when the operating state of the external operator changes. and musical tone generation control means for controlling the musical tone generating means so that the musical tone generated by the external operator is continuously generated by the musical tone generating means until the operation state of the external operator changes again. electronic stringed instrument. 2. The pitch setting means has a pickup provided for each string that converts the vibration of the string into an electrical signal, and a pitch extraction means that extracts the pitch of the string vibration from the electric signal obtained by the pickup, 2. The electronic stringed instrument according to claim 1, wherein pitch data is set based on the extracted pitch. 3. The pitch setting means includes a frett switch that detects a frett operation position for each string, and sets the pitch data based on the on/off state of the frett switch.
The electronic stringed instrument described. 4. Claim 1, wherein the external operator is a foot switch that is turned on when stepped on and turned off when not stepped on.
, 2 or 3. 5. When a plurality of pitch data are set by the pitch setting means in accordance with operations at a plurality of fret operation positions, the musical sound generating means is configured to adjust the pitch data based on each of the pitch data. 5. The electronic stringed instrument according to claim 1, 2, 3, or 4, wherein the electronic stringed instrument is capable of generating a plurality of musical tones having corresponding pitches.
