摘要： A detecting device for detecting the positions where strings are operated, and an electronic musical instrument using the detecting device, such as an electronic stringed instrument of an electronic keyboard instrument. Wherein each of frets, with which conductive strings are brought into contact, is formed of a two-layer structure of a conductive member and a resistance member provided on the conductive member. Voltage pulses are sequentially applied to either the conductive strings or the conductive members of the frets and a voltage pulse is detected from a conductive member or a string, thus detecting a position in which a string is stopped against the fret.

摘要： A plurality of strings are extended along a surface of a body, and an operation by a player with respect to the strings is detected by two detection systems. The first detection system is operated when a string vibration is started, and electrically obtains an operated fret position of the string by detecting an ON/OFF operation of a switch arranged below each fret. The second detection system is enabled after the first detection system is enabled, and directly measures a pitch period of the string vibration. The second detection system detects a change in pitch by a choking operation or an arming operation of a tremolo arm with respect to the string after tone generation is started.

摘要： An electronic musical instrument shaped like an electric guitar sounds individual notes that are synthesized to sound like an electric guitar. These notes may either be selected randomly selected by a player or from segments of prearranged musical tracks. The instrument provides for maintaining the tempo of manually played or preprogrammed notes, synchronizing the transitions between sequentially selected musical tracks, overlaying manual notes on the tracks, and a number of electric guitar-like sound effects including vibrato, chorus, overdrive, slurs and soft picks.

摘要： Root and type of a chord are discriminated at discriminators in accordance with the operation status on a fingerboard. The chord is designated according to a simplified fingering rule predetermined on the fingerboard so as to designate the chord. An automatic accompaniment or a manual play is performed according to the discriminated chord obtained at chord discriminating device.

摘要： A real-time polyphonic pitch controller and process for controlling notes or tones emanating from signal synthesizers such as used in the performance of music. The controller comprises a body with key controllers, each of which activates a pre-programmed note; a strumming controller which automatically activates selected key controlled notes in a pre-programmed sequence and rate; and controls and displays used for programming and performance. Extending longitudinally from the body is a guitar-like neck graduated by fret markings and over which slides a hand controller incorporating finger levers. Sliding the hand controller creates portamento, vibrato or glissando effects on the notes activated by the key controllers. Also, each finger lever of the hand controller when depressed raises and/or lowers its own peculiar, pre-programmed combination of individually voiced notes by pre-programmed amounts. Some note pitches may be raised, others lowered, and still others unaffected by the movement of a lever, and the finger levers may be operated separately or in combination. When only partially depressed, a lever alters the pitch of the pre-selected combination of individually voiced notes fractionally, in porportion to the lever's depression. The controllers may further operate in conjunction with a computer program which interprets and processes the controller's pitch altering signals and teaches the musician how to perform on the instrument expressively. In an alternative embodiment, the controller incorporates a sliding fretted hand controller with finger pads rather than levers.

摘要： In apparatus for detecting string stop position for string instruments, there is provided fret detecting means comprising coils which generate an induced voltage by means of an electric current flowing through each of the frets, whereby the string stop position may be detected on the basis of the induced voltage generated by the coil which corresponds to the fret contacting the string when the string is stopped.

摘要： An electronic sensing system is disclosed for sensing fingering on a stringed and fretted musical instrument, such as a guitar, to produce therefrom electronic signals truly representative of the music created by the musical instrument. Sensing includes detection of the musical pitch created by each selected string and fret combination, as well as detection of the vibration state of the selected string and any pitch variations induced by the performer through string bending. The system is microprocessor controlled with each string of the instrument being successively and repeatedly sampled during playing of the instrument, and outputs indicative of the fret-string combination then being fingered, the vibration state, and any string bending are coupled to the microprocessor in digital form, and with the microprocessor then utilizing the then supplied information to provide an output suitable for coupling to a synthesizer to thereby enable performance of the music then being played by the performer utilizing the stringed and fretted musical instrument.

摘要： A musical instrument is structured as a guitar and incorporates electronic circuitry to synthesize musical tones. The instrument is played in the fashion of a guitar with tones generated in response to switches activated through strumming action. The pitch of the tones is controlled by touch-sensitive switch devices mounted at addresses corresponding to fret and string locations. The instrument may be polyphonic with separate tones generated by activation of a plurality of devices corresponding to strings.

摘要： Musical instruments playable in duet fashion by one player includes a stringed instrument with segmented frets. A control system for the other instrument includes a control circuit for each string and which has actuating circuits that are associated with the open and keyed string tones playable on the string. The actuating circuits associated with the second and higher string keying positions are enabled by simultaneous string contact with adjacent fret sections, and simultaneous string contact with a plate and fret segment at the first position serves to enable the actuating circuit associated with the first string keying position. A disabling circuit has components associated with each actuating circuit and which disable the associated actuating circuit in response to output signals of the actuating circuits associated with the higher keying positions. Open tone sensing circuits are avoided in one embodiment especially designed for chord playing players of the stringed instrument and in which simultaneous signals from a predetermined number of disabling circuits that are enabled by simultaneous keying of different strings serve to control an auxiliary circuit to enable the actuating circuits associated with the open tones of the unkeyed strings.
