Computing devices and methods for providing a music customization graphical user interface (GUI) to a user computing device are disclosed. The music customization GUI comprises song name selectors that each correspond to a different song and a music player region that includes a song customization selector. A customization window comprises music stem indicators that each correspond to at least one music stem of a selected song. The customization window also comprises mixing buttons that include a first mixing button configured to add a corresponding music stem to a user song mix, and a second mixing button configured to remove the music stem from the user song mix. A download button is configured to download a file comprising the user song mix to a user computing device.

An electronic instrument includes a plurality of music-playing operators which designates pitch data in accordance with a music-playing operation and at least one processor which instructs a sound source which generates music sounds to emit sounds, in which the at least one processor, in a case where the music-playing operation meets a first instruction condition, instructs the sound source to emit the sound in a first sound emission form which corresponds to pitch data which meets the first instruction condition which is designated in accordance with the music-playing operation, and in a case where the music-playing operation meets a second instruction condition which is different from the first instruction condition, instructs the sound source to emit a sound which is different from the sound which is emitted in the first sound-emission form, that is, in a second sound-emission form which corresponds to pitch data which meets the second instruction condition which is designated in accordance with the music-playing operation.

The present disclosure provides a portable music production apparatus which a USB interface for connecting to a computer device, the apparatus comprises a first control element which is configured to provide a pitch bend functionality and a second control element which can be assigned to modulate any parameter a user desires like a modulation wheel. The apparatus can also be provided with additional programmable control elements.

Digital signal processing and machine learning techniques can be employed in a vocal capture and performance social network to computationally generate vocal pitch tracks from a collection of vocal performances captured against a common temporal baseline such as a backing track or an original performance by a popularizing artist. In this way, crowd-sourced pitch tracks may be generated and distributed for use in subsequent karaoke-style vocal audio captures or other applications. Large numbers of performances of a song can be used to generate a pitch track. Computationally determined pitch trackings from individual audio signal encodings of the crowd-sourced vocal performance set are aggregated and processed as an observation sequence of a trained Hidden Markov Model (HMM) or other statistical model to produce an output pitch track.

An electronic device comprising circuitry configured to separate by audio source separation a first audio input signal into a first vocal signal and an accompaniment, and to transpose an audio output signal by a transposition value based on a pitch ratio, wherein the pitch ratio is based on comparing a first pitch range of the first vocal signal and a second pitch range of the second vocal signal.

A music generation device includes: an acquisition unit that acquires first stream data and second stream data different from the first stream data; an accompaniment generation unit that generates accompaniment information, which is music data indicating an accompaniment, based on a change in the first stream data; a melody generation unit that generates melody information, which is music data indicating a melody, based on a change in the second stream data; a melody adjustment unit that adjusts the melody information in accordance with a key of the accompaniment indicated by the generated accompaniment information; a music combining unit that combines the accompaniment information and the adjusted melody information to generate musical piece information; and an output unit that outputs the generated musical piece information.

The implementation of modal processors, which involve the parallel combination resonant filters, may be costly for applications such as artificial reverberation that can require thousands of modes. In one embodiment, the input signal is decomposed into a plurality of subbands, the outputs of which are downsampled. In each downsampled band, resonant filters are applied at the downsampled sampling rate, and their output is upsampled and filtered to form the band output. In these and other embodiments, a feature of responses of the mode filters have been optimized to minimize an aspect of a residual error after a point in time.

The present invention relates to a method for processing and playing audio data comprising the steps of receiving mixed input data and playing recombined output data. Furthermore, the invention relates to a device 10 for processing and playing audio data, preferably DJ equipment, comprising an audio input unit for receiving a mixed input signal, a recombination unit 32 and a playing unit 34 for playing recombined output data. In addition, the present invention relates to a method and a device for representing audio data, i.e. on a display.
