Abstract
Abstract An electronic stringed instrument employs a plurality of sensors or monitors for instrument performance. Preferred sensors or monitors include a detector for detecting that a string of the instrument is vibrated, an apparatus for evaluating a string-vibration strength or a string touch, an apparatus for discriminating a fret operation position on a fingerboard or a fundamental frequency of a vibration of the vibrated string, a tremolo arm sensor, and a string-bending sensor. These performance input parameters are assigned to various control functions for musical tones generated by a sound source and/or various control functions for effects added to these musical tones by an effector. The function assignment is preferably programmable. In an operation, a music control apparatus control the sound source and/or effector in response to a performance monitor so that musical tones for the strings can be distinguished from each other or effects for the musical tones can be distinguished from each other. Therefore, a performance with the stringed instrument by a player can be fully expressed.
