A method comprises obtaining a playlist that comprises a plurality of audio items, and dividing the playlist into a plurality of coherent groups, wherein each coherent group comprises a respective sequence of audio items of the plurality of audio items with a common attribute. For a respective coherent group of the plurality of coherent groups, the method comprises determining a parameter value of a first audio item of the respective sequence and adjusting a parameter value of a second audio item of the respective sequence based on the determined parameter value of the first audio item, to form a transition between the first and second audio items. The first and second audio items are adjacent in the respective sequence. The transition is provided to a second electronic device for playback.

A content control device includes: a plurality of controls to which a plurality of parameters for controlling properties of a content containing at least one of sound and video are respectively assigned, each of the plurality of controls outputting a first indicated value in accordance with an operation amount of the control; and a processor configured to previously create setting information used to determine respective values of the plurality of parameters in accordance with the second indicated value; determine the values of the plurality of parameters corresponding to the second indicated value respectively in accordance with the second indicated value and the setting information; and revise each of the values of the parameters to be determined in accordance with the first indicated value outputted for the control assigned to the parameter.

The teachings described herein are generally directed to a system, method, and apparatus for separating and mixing tracks within music. The system can have a video that is synchronized with the variations in the musical tempo through a variable timing reference track designed and provided for a user of the preselected piece of music that was prerecorded, wherein the designing of the variable timing reference track includes creating a tempo map having variable tempos, rhythms, and beats using notes from the preselected piece of music.

A musical performance device is provided by which, even by a novice user's operation, an attack sound, which is musically important, can be emitted as intended. In the device, sequence data representing each note of a musical piece for musical performance is provided for each track. When the sequence data of a certain segment of at least one track among these tracks is being replayed, if a target track to be replayed is specified from among the tracks not being replayed, the sequence data of the certain segment of the target track is replayed at a speed higher than a normal speed in accordance with a calculated playback rate, and then the target track and the other track are replayed at the normal speed.

A content control device includes: a plurality of controls to which a plurality of parameters for controlling properties of a content containing at least one of sound and video are respectively assigned, each of the plurality of controls outputting a first indicated value in accordance with an operation amount of the control; and a processor configured to previously create setting information used to determine respective values of the plurality of parameters in accordance with the second indicated value; determine the values of the plurality of parameters corresponding to the second indicated value respectively in accordance with the second indicated value and the setting information; and revise each of the values of the parameters to be determined in accordance with the first indicated value outputted for the control assigned to the parameter.

Audio mix information is received from a plurality of users. Mix rules are determined from the audio mix information from the plurality of users, wherein the mix rules include a first mix rule associated with a first audio item. The first mix rule relates to an overlap of the first audio item with another audio item. The first mix rule is made available to one or more clients. After making the first mix rule available, an indication, from a respective client device, that the first audio item is to be mixed with a second audio item at the respective client device in accordance with the first mix rule is received. In response to the indication, a specification of the first mix rule is transmitted to the respective client device to be applied by the respective client device to generate a transition between the first audio item and the second item.

Sensor data generated by one or more sensors associated with a digital content playback device can be used to identify that a modification to a current audio content item being supplied to a user by the digital content playback device is indicated. The current audio content item can be modified accordingly. Methods, systems, articles of manufacture and the like are also described.

A method for scrolling a musical score on a screen of a device, comprising: loading a file having a digital score in a piece of memory of said device, wherein said digital score is in a digital format for representing musical notation; displaying a plurality of notes or at least one measure from said score on the screen. The method further comprises: scrolling said score in a continuous way by moving the notes or measures displayed on the screen, in such a way that additional notes of music or additional measures start to appear on the screen while the already scrolled notes or measures start to disappear from the screen; adjusting the scrolling speed according to the displayed notes or measures and to a tempo. Device, computer program product and computer-readable memory/medium.

An electronic musical instrument allows a player to operate operators as least number of times as possible to play music, and the player can play music easily and agreeably, using the instrument. Every measure decided by plural beats counted based on a designated meter a prior tone is determined from among automatic playing music data. The prior tone is a musical tone which is made note-on for example at a timing of a downbeat in the measure. If a candidate for the prior tone is one of chord composing tones, and the one of chord composing tones can compose a melody, then such musical tone is decided as the prior tone. The prior tones successively decided from the beginning of the automatic playing music data are indicated to the player as lighted up keys. The player operates the lighted up keys successively to perform the automatic playing music data.

A musical composition is varied using a computational model of rubato. Rubato is modeled by changes to the symbolic onset and/or symbolic offset of each note, which allows for a greater flexibility in timing modifications, such as asymptotic tempo and localized retrogrades. A user selects notes to be modified (e.g., by plotting points to modify notes over a selected interval), and a curve fitting (e.g., a cubic spline interpolation) is used to determine modifications for other notes in the composition. These symbolic onset/offset modifications may also be translated into tempo modifications. The symbolic onset and/or offset modifications are applied to the composition to produce an adjusted musical composition, to which rubato has been applied. Rubato profiles can similarly be extracted from existing musical recordings and used to characterize the recordings, such as for training machine learning models and recommender systems.
