An apparatus, method, and computer-readable storage medium that generate a harmonized musical piece. The method includes receiving a chord selection including a musical key and a scale selection, generating, within a digital audio work session, a chord progression sequence based on the received chord selection, in response to a detected chord selection change, modifying the chord progression sequence to include a chord progression corresponding to the chord selection change, setting the chord progression sequence as a master sequence, in response to detecting a second progression sequence within the digital audio work session, transmitting an identifier to the second progression sequence setting it as a slave sequence, and establishing a synchronized communication link between the master and the slave sequences such that changes made in the master sequence are automatically effectuated in the slave sequence, and combining the master sequence and the slave sequence to form a composed musical piece.

In a performance operator group, a partial region including at least one first performance operator and at least one second performance operator is set as a first key region. An allocator allocates musical sound data to the first key region. An operation detector detects an operation using each of the plurality of first and second performance operators of the performance operator group. A reproduction controller carries out first control relating to a reproduction method of the allocated musical sound data in response to detection of an operation using one of the first and second performance operators in the first key region, and carries out second control relating to the reproduction method of the allocated musical sound data and being different from the first control in response to detection of an operation using another one of the first and second performance operators in the first key region.

A keyboard musical instrument, a method, and a non-transitory computer-readable recording medium that improve operability are provided. An electronic musical instrument comprises a keyboard including plural white keys each of which is allocated with plural characters and plural black keys, and a controller. The controller executes, in a musical sound producing mode that is set, accepting a sound producing instruction of a musical sound in response to an operation of the keyboard, and, in a symbol input mode that is set, according to both a white key designated from the plural white keys and a black key designated from the plural black keys, accepting an input of a character among the plural characters allocated to the white key designated from the plural white keys.

An accordion includes a right hand play side, a left hand play side, a bellow provided between the right hand play side and the left hand play side. A plurality of columns of buttons provide on at least one of the right hand play side and the left hand play side. Each of the plurality of columns may have at least three buttons to which three single pitches are assigned, the three single pitches constituting a triad major chord. Embodiments of the present invention provide a user-friendly system for accordionists that can also cover more than 90% of the accordion songs being public in the world.

A media application for providing outputs (e.g., audio outputs) in response to inputs received from an input device is provided. The media application may connect input mechanisms of an input device with parameters of channel strips (e.g., which may define output sounds) using an intermediate screen object. The media application may first assign an input mechanism to a screen object, and separately map a screen object to a channel strip parameter. The media application may map a screen object to several channel strips simultaneously such that, based on the value of the screen object, the volume of each of the several channel strips changes. The media application may provide a graphical representation of available channel strips using layers. As the media application accesses a channel strip, the appearance of the portion of the layer associated with the channel strip may change. The media application may also allow the patches, which may include several channel strips, to survive after a new patch is selected instead.

A smart music device and process provide users with an interface to play a selected song in the correct song key. The device includes a graphical user interface with areas demarcated by translucent conductive ink printed on the layer's underside. A layer of force sensor resistors (FSRs) are under the areas. Touching one of the areas closes a circuit between then conductive ink and FSR triggering a note to be played. The demarcated areas are illuminated to guide the user on scale and root node position. Metadata in memory storage includes the song key which is used during song playback to trigger assignment of the key correct scale across the FSRs and illuminate its root position of musical notes. Touching an area triggers a signal sent to a connected musical instrument to play the note.
