An electronic musical instrument includes at least one processor that, in accordance with a user operation on an operation unit, obtains lyric data and waveform data corresponding to a first tone color; inputs the obtained lyric data to a trained model so as to cause the trained model to output acoustic feature data in response thereto; generates waveform data corresponding to a singing voice of a singer and corresponding to a second tone color that is different from the first tone color, based on the acoustic feature data outputted from the trained model and the obtained waveform data corresponding to the first tone color; and outputs a singing voice based on the generated waveform data corresponding to the second tone color.

An electronic musical instrument includes an operation unit that receives a user performance; and at least one processor. wherein the at least one processor performs the following: in accordance with a user operation specifying a chord on the operation unit, obtaining lyric data of a lyric and obtaining a plurality of pieces of waveform data respectively corresponding to a plurality of pitches indicated by the specified chord; inputting the obtained lyric data to a trained model that has been trained and learned singing voices of a singer so as to cause the trained model to output acoustic feature data in response thereto; synthesizing each of the plurality of pieces of waveform data with the acoustic feature data so as to generate a plurality of pieces of synthesized waveform data; and outputting a polyphonic synthesized singing voice based on the generated plurality of pieces of synthesized waveform data.

An electronic musical instrument includes: a memory that stores lyric data including lyrics for a plurality of timings, pitch data including pitches for said plurality of timings, and a trained model that has been trained and learned singing voice features of a singer; and at least one processor, wherein at each of said plurality of timings, the at least one processor: if the operation unit is not operated, obtains, from the trained model, a singing voice feature associated with a lyric indicated by the lyric data and a pitch indicated by the pitch data; if the operation unit is operated, obtains, from the trained model, a singing voice feature associated with the lyric indicated by the lyric data and a pitch indicated by the operation of the operation unit; and synthesizes and outputs singing voice data based on the obtained singing voice feature of the singer.

Audio translation system includes a feature extractor and a style transfer machine learning model. The feature extractor generates for each of a plurality of source voice files one or more source voice parameters encoded as a collection of source feature vectors, and generates for each of a plurality of target voice files one or more target voice parameters encoded as a collection of target feature vectors. The style transfer machine learning model trained on the collection of source feature vectors for the plurality of source voice files and the collection of target feature vectors for the plurality of target voice files to generate a style transformed feature vector.

A simple yet effective sustainer for electronic stringed instruments having a bridge pickup and a neck pickup. A driver assembly, disposed adjacent the neck pickup of the instrument, includes a plurality of electromagnetic transducers operative to induce vibrations in the strings. A battery-operated electronic amplifier has an input adapted for connection to the bridge pickup, and an output connected to the driver assembly, such that, when the instrument is played, string vibrations sensed by the bridge pickup are amplified by the electronic amplifier and used to drive the driver assembly, thereby sustaining the played string vibrations. The driver assembly may be disposed in a ring that surrounds the neck pickup of the instrument. The ring may include an ON/OFF switch that routes power from the battery to the electronic amplifier and simultaneously deactivates the bridge pickup in the ON position. The ring may further include a phase reversal switch.

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.

A virtual instrument can manage separate static and dynamic samples for various notes that can be played by the virtual instrument. In some cases, the static samples correspond to resonance sounds recorded for an instrument and are the same for every note. However, the dynamic samples may correspond to isolated sounds that are recorded for each variation of a note that can be played. In response to a user's selection of a note on a user interface of the virtual instrument, the virtual instrument may determine a rule for layering the various static and dynamic samples for playback.

The invention relates to an attachment arrangement for the strings of a stringed instrument, especially a guitar. To the body of the stringed instrument is attached a bridge body, first restraining means for restraining the strings from the first end area, second restraining means, which are arranged in conjunction with the bridge body for restraining the strings from the second end area. Lever means are arranged in conjunction with the bridge body in order to move the second restraining means for temporarily loosening and/or tightening the strings by means of a lever part included in the lever means. The lever means are provided with moving means comprising at least one moving mechanism, which is a mechanism separate from the lever means. One or more second restraining means are arranged to move with respect to the bridge body. The moving means are arranged to transmit the movement of the lever means into the desired movement of one or more restraining means.

A musical instrument with an improved interface for playing the instrument is provided. The musical instrument may be configured with a musical scale and a key. An input interface of the musical instrument may be configured based on the scale and key to allow a player of the instrument to easily play multiple collections of notes, or chords, in a simplified manner. For example, the improved interface allows a user to play a number of chords or other collection of notes without having to depress or engage a number of sound actuators at different locations along instrument.

A method includes displaying, by an electronic device, a first interface, where the first interface includes a recording button used to record a first song, obtaining, by the electronic device, accompaniment of the first song and feature information of a cappella of an original singer, starting to record a cappella of the user that is sung by the user, and displaying, by the electronic device, guidance information on a second interface based on the feature information of the a cappella of the original singer, where the guidance information guides one or more of breathing and vibrato during the user's singing.
