A manual vibrato control device, system and processing arrangement are disclosed. A manual vibrato includes a rotatable shaft, a raised cam section on the shaft, first and second biased collars received on the shaft either side of the cam section, the bias of the first collar being rotationally opposite to the bias of the second collar such that as the shaft rotates in one direction, it receives a return force from the first collar but does not rotate the second collar, and vice versa.

Also disclosed are processing techniques to take the rotational data from rotational sensors, preferably Hall Effect, on the shaft and generate pitch change instructions for a pitch modification device. The mapping is user controllable to produce desired effects and performance.

The invention relates to an electrical stringed instrument system comprising an electrical stringed instrument. The electrical stringed instrument comprises i) an audio output circuit electronically connected to said one or more pickups, and to a first channel of a multichannel output jack; and ii) a first communication circuit comprising a variable impedance unit, and electronically connected to a second channel of said multichannel output jack.

In summary, the integral visual learning system for electric guitar and similar instruments, to which the present invention refers, has a learning method that is integrated into an application for mobile devices and contains all the learning methodology and knowledge that It will be transmitted to the user to develop the ability to play the instrument. This learning method is connected to a display device on the instrument fretboard by means of a Bluetooth communication device and allows the user to visualize by means of the illumination of transparent resins, the information of notes, chords, musical scales, and other information sent from the learning method. The system also has an augmented reality device that is made up of augmented reality glasses that allow the user to visualize a virtual teacher who provides the user with theoretical information, as well as images superimposed with the position and shape of the fingers of your left/right hand to correctly play the notes, chords and musical scales. Likewise, the system has a feedback device that identifies the notes and/or chords that the user played on the instrument and compares them with the notes and/or chords requested in the exercises contained in the learning method, this allows the users identify the precision with which they performed the exercises and gradually improve until they obtain the required mastery at the different learning levels. Finally, the system has a recharge device for a lithium ion battery that powers the entire system.

The disclosure discloses a timbre fitting method and system based on time-varying multi-segment spectrum, the system includes an input device for obtaining audio signals of musical instruments and a segmented multi-model compensation module. The segmented multi-model compensation module learns a timbre of a source musical instrument and a target musical instrument, and establishes a multi-segment model of the sound feature of the source musical instrument and a multi-segment model of the sound feature of the target musical instrument. The sound feature is set to be based on maximum amplitude of the audio signal played the same sequence on the target musical instrument and the source musical instrument, and the audio signal of the sequence is divided into multiple segments according to the amplitude. The sound feature includes frequency spectrums of notes respectively within each amplitude range. The segmented multi-model compensation module establishes a multi-model structure with time-varying gain.

An electromagnetic multi-function multi-purpose chordo-phone musical instrument upon which any form or style of music may be played in any position by a performer standing or seated, in a fixed location or moving throughout a performance venue. The player may initiating the vibrations of each string, any combination of strings, or all of the strings with a plectrum or the fingers of one or both hands, singly or in any combination and such vibrations will continue until their eventual natural termination unless damped and/or muted by the player using the fingers or the palm of one or both hands singly or in any combination. The shape and style of the rigid frame of the instrument is not limited by the need for frets, a fretboard, or keys.

This invention eliminates most mechanical switching in vibrational pickup circuits by using variable gains to combine signals of sensors in differential amplifiers as J1 humbucking pairs for J>1 number of sensors, with the sensors matched to produce the same level and phase of unwanted hum from external sources. It can also combine J>1 number of matched sensors with K>1 number of dissimilar sensors which are matched only to each other in the same manner. This produces not only all the possible mechanically switched humbucking signals, but all the continuously-varying combinations of humbucking signals in between.

A hand-held strumming device includes a hollow body, a power source, a motor, a regulator, and a strummer. The power source is disposed in the hollow body. The motor is in electrical communication with the power source. The regulator is in electrical communication with both the motor and the power source. The regulator is configured to selectively adjust a rotational speed of the motor. The strummer is rotatably disposed on the disk. The strummer is configured to be presented to strings of a stringed instrument upon rotation of the motor to strum the strings.
