Systems and methods are directed to generating music. In one example, an electronic musical instrument includes a first handheld unit. The electronic musical instrument further includes a second handheld unit, the second handheld unit being communicatively coupled to the first handheld unit. The first handheld unit includes a plurality of input controls configured to indicate a selection of a note of a musical scale. The second handheld unit is configured to initiate output of the selected note.

The present invention provides a method for processing audio data, comprising the steps of providing a first audio track of mixed input data, said mixed input data representing an audio signal containing a plurality of different timbres, decomposing the mixed input data to obtain decomposed data representing an audio signal containing at least one, but not all, of the plurality of different timbres, providing a second audio track, analyzing audio data, including at least the decomposed data, to determine at least one mixing parameter, and generating an output track based on the at least one mixing parameter, said output track comprising first output data obtained from the first audio track and second output data obtained from the second audio track.

To generate a melody, one or more machine-readable constraints are accepted from a user through a user interface. The constraints include rhythm constraints and pitch constraints. A sequence of musical elements is generated based on the constraints, each of the musical elements specifying, in machine-readable data, a musical pitch or silence and a duration of the musical pitch or silence. The pitch constraints prescribe pitches in the sequence of musical elements and the rhythm constraints prescribe rhythm of the sequence of musical elements. The sequence of musical elements is rendered in human-perceivable form as a melody.

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 for processing and playing audio data, preferably DJ equipment, comprising an audio input unit for receiving a mixed input signal, a recombination unit and a playing unit 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.

Provided is a musical instrument controller capable of accurately controlling a musical sound parameter. This musical instrument controller includes: a reception means for receiving, from a musical performance device, a sound emission start signal transmitted on the basis of a musical performance operation; a sensor for detecting an amount of displacement from a reference position; and a control means for generating a control signal on the basis of the amount of displacement from the reference position and transmitting the control signal to a sound generation device. The control means sets the reference position on the basis of the sound emission start signal received from the musical performance device.

A device for processing audio signals, including: first and second input units providing first and second input signals of first and second audio tracks, a decomposition unit to decompose the first input audio signal to obtain a plurality of decomposed signals, a playback unit configured to start playback of a first output signal obtained from recombining at least a first decomposed signal at a first volume level with a second decomposed signal at a second volume level, such that the first output signal substantially equals the first input signal, and a transition unit for performing a transition between playback of the first output signal and playback of a second output signal obtained from the second input signal. The transition unit has a volume control section adapted for reducing the first and second volume levels according to first and second transition functions.

A computerized process, a system, and non-transitory computer-readable medium having computer-executable instructions for mixing audio tracks according to a template. The process may include receiving at least one request for each of a plurality of time blocks of a template; querying a catalog of songs and/or song portions in a database to compile a candidate list of songs and/or song portions that substantially meet the at least one request of a first time block of the plurality of time blocks; choosing a first song portion and a second song portion from the candidate list for the first time block; compiling the first song portion and the second song portion to form at least a portion of the first time block, including blending a temporal length of the first song portion and the second song portion; and generating an audio file with the plurality of time blocks.

A musical sound that is rich in amusement can be provided. A musical sound control device includes: a plurality of operators; a musical sound processing part configured to repeat a process of controlling a musical sound in each of a plurality of steps in accordance with control information set by the plurality of operators; and a control part configured to stop an operation of the musical sound processing part in a case in which the process of controlling a musical sound of the plurality of all the steps using the musical sound processing part has gone through one cycle in a case in which a predetermined condition is satisfied.

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 disclosure relates to a method of automatically preparing a MIDI file based on a target MIDI file comprising respective note information about each of a plurality of target notes and a source MIDI file comprising respective note information about each of a plurality of source notes. Each note information comprises pitch information defining a pitch of the note. The method comprises ranking the plurality of target notes based on the pitch of each target note. The method also comprises, for each of the ranked target notes, removing the pitch information from the note information of the target note. The method also comprises, for each of the ranked target notes, replacing the removed pitch information with pitch information of a corresponding source note, whereby the target note has the same pitch as the corresponding source note, forming a plurality of new notes of a new MIDI file.
