A system and method for delivering dynamic user-controlled musical accompaniments, utilizing a computing device with a graphical user interface, an application running on said device, optionally using peripheral external or integrated devices, and a variety of controls to dynamically alter the playback of a pre-recorded accompaniment track, saving the altered accompaniment track for later use, and for sharing with other users via a cloud service engine, if desired.

According to a preferred aspect of the instant invention, there is provided a system and method that allows the user to implement an intelligent automatic music jam mode. The jam mode is adaptable to both novice and professional users, wherein the user is able to define in real-time a plurality of different settings which are instantly utilized and which provide instant results for the user. In an automatic mode the instant invention will pick settings autonomously, for example song part definition, tone pitch and instruments. In absence of constant user interaction the instant invention enters a creative mode wherein the initial user defined settings are varied to introduce variance into the jam session. The system and method also monitors data input by instruments connected and played by the user and intelligently adapts the setting selection accordingly.

A device for controlling playback of digital multimedia displays in first and second portion a representation of a part of the multimedia data, where in the first portion a representation of a part of the multimedia data, which is displayed on the second portion, is displayed, and where the first portion operatable in at least a first and a second mode, where in the first mode independently of a position of a touch point a direction and a speed of the playback is controllable in dependence of a change of the touch point, and in the second mode a new playback position is definable in dependence of the position of the touch point,
for displaying in the second portion a marker for indicating a neighbourhood around the playback position, and
for switching the modus of the first portion, when the marker is moved by user input.

Sensory outputs are synchronized to input tempos for providing soothing and other effects for children and other persons. In example embodiments, juvenile products such as rockers and swings have motors that are controlled to produce an oscillatory motion with an adaptive tempo that is synchronized to rhythmic inputs such as a parent's heartbeat. In other example embodiments, juvenile products such as music players are controlled to output signals to play songs via speakers with an adaptive tempo that is synchronized to rhythmic inputs such as an infant's respiratory rate.

An electronic musical instrument in one aspect of the disclosure includes; a plurality of operation elements to be performed by a user for respectively specifying different pitches; a memory that stores musical piece data that includes data of a vocal part, the vocal part including at least a first note with a first pitch and an associated first lyric part that are to be played at a first timing; and at least one processor, wherein if the user does not operate any of the plurality of operation elements in accordance with the first timing, the at least one processor digitally synthesizes a default first singing voice that includes the first lyric part and that has the first pitch in accordance with data of the first note stored in the memory, and causes the digitally synthesized default first singing voice to be audibly output at the first timing.

An acoustic device includes: a first display unit; a second display unit; an operation unit configured to receive a user's operation; a judging unit configured to judge a type of the operation performed on the operation unit; and a display controller configured to, in response to the type of the operation determined by the judging unit, change display contents of the first display unit to display contents corresponding to the type of the operation and display on the second display unit at least a part of the display contents having been displayed on the first display unit.

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.

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 method comprises obtaining a playlist that comprises a plurality of audio items. The playlist is divided into a plurality of coherent groups. 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, a parameter value of a first audio item of the respective sequence is determined, a parameter value of a second audio item of the respective sequence is adjusted based on the determined parameter value of the first audio item, and a transition media item is formed. The transition media item corresponds to a transition between the first and second audio items that are adjacent in the respective sequence. The transition media item is provided to a second electronic device.

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 performance 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 performance.
