    摘要： An electric stringed instrument (1) having a device (G) for sustaining the vibration of a string (6) comprises an electromagnetic pickup (8) for converting the vibration of the string to an electric signal, amplifying means (18) for amplifying said electric signal, and an electromagnetic driver (17) for converting said amplified signal to a driving force to thereby drive the string. The electromagnetic pickup (8) and the electromagnetic driver (17) are placed at a right angle or a predetermined angle of inclination to each other such that induced electromotive forces caused by magnetic flux from said electromagnetic driver negate each other or are not produced at said electromagnetic pickup to thereby reduce the magnetic feedback.

    摘要： The apparatus is designed for distorting, on selections operated by the musicians, an audio signal such as that generated by an electronic musical instrument, and permits such distortion to be achieved, particularly in an automatic mode, without any substantial change in the volume, base content or treble content of the audio output. The apparatus comprises means (18, 20, 22, 24) for distorting the audio signal by a controlled degree. The distortion causes variations in the volume of the output as the degree of distortion increases and also causes increases in the bass and treble content of the output with increasing distortion. The volume variation is compensated for by providing means for automatically maintaining the volume of the audio signal outputted from the distortion element substantially uniform regardless of the degree of distortion, the compensation occuring solely as a function of the selected degree of distortion. The circuit may comprise a compressor prior to distortion. Adjustable filtering may also be applied at the input to the distortion element.

    摘要： When picking of a string is performed, the vibration of the string is detected by string trigger switches (TSW) accurately and quickly. When a fret operation position is changed during generation of a musical tone from musical tone generating circuit (60) caused by the string picking, the pitch of the musical tone is changed according to outputs of fret switches (FSW) to the one corresponding to the new fret operation position without generating a new musical tone. When the same string is stroked successively, the succeeding musical tone is generated while keeping the reverbera­tion of the previous musical tone under the control of microcomputer (30). The musical tone once generated will be stopped from being generated upon elapse of a predetermined time from the beginning of the tone gen­eration, irrespective of the type of its timbre. When a change of a fret operation state is detected by switch status detection circuit (50) to change to an open-­string operation state after the string picking, the generation of the musical tone being generated from circuit (60) stops at that timing. When this change occurs, it is selectable whether the generation of the musical tone is to be stopped or its pitch is to be changed to the one corresponding to the open-string operation state. The generated musical tone can freely be stopped from being generated through a manual opera­tion.

    摘要： An electronic stringed instrument includes strings (15₁ to 15₆), a plurality of metal frets (13₁ to 13₆), an ultrasonic transmitter/receiver (16₁ to 16₆) and a fret discriminator (22). The strings are kept taut above an instrument body (11). The frets (13 i ) are arranged below the strings (15 i ) along their extension direction. When a player depresses a given string (15 i ) to be picked, at least one of the metal frets (13 i ) is brought into contact with the given string. The transmitter/receiver (16 i ) is coupled to specified positions of the strings (15 i ) and causes ultrasonic vibrations of the strings and receives an echo vibration generated as a reflection of the ultrasonic vibration at a fret contacting the given string. The fret discriminator (22) discriminates the fret contacting the string among the metal frets (13 i ) according to the time difference between the generation of the ultrasonic vibration and the receipt of the echo vibration by the transmitter/receiver (16 i ).
