[Problem] To provide an arpeggiator capable of creating a rich arpeggio performance that includes multiple pieces of performance information, and a program equipped with a function therefor. [Solution] When the key press mode for a sounding part is a chord, a synthesizer 1 acquires all note numbers from a remain table for the sounding part in a setting table 11e and stores all the note numbers in an Arp note memory 12b. This allows all the notes corresponding to the note numbers set in the remain table to be concurrently generated at the sounding time set in an Arp pattern. That is, an expressive arpeggio based on a chord made up of all the notes corresponding to the note numbers set in the remain table can be produced.

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.

An electronic musical instrument includes: a chord-playing input device; a sounding part that emits chord sounds; and a display part that displays an image. The chord-playing input device includes: a chord designating button group assigned with chords; a chord changing button group assigned with change methods for changing an assignment state for the chord designating button group; a sounding information generating part that generates sounding information for making the sounding part emit the sound of the chord corresponding to operation for the chord designating button group and chord changing button group; and a display information generating part that generates display information for making the display part display a plurality of chord images and change method images in the same arrangement order as those of the chord designating button group and chord changing button group.

A virtual instrument can manage separate static and dynamic samples for various notes that can be played by the virtual instrument. In some cases, the static samples correspond to resonance sounds recorded for an instrument and are the same for every note. However, the dynamic samples may correspond to isolated sounds that are recorded for each variation of a note that can be played. In response to a user's selection of a note on a user interface of the virtual instrument, the virtual instrument may determine a rule for layering the various static and dynamic samples for playback.

When a harmony function is on state, a generator determines a chord based on one or more notes of depressed keys in a chord kea area, automatically generates one or more additional notes having pitches which harmonizes the pitch of the note of the depressed key in a performance key area according to the determined chord, and inputs the “note of the pressed key in the performance key area+additional notes” to an assignment controller. The assignment controller assigns plural parts (timbres) to the inputted notes, and sounds the notes in timbres of the plural parts according to the assignment. That is, tone generation assignment process is performed regarding not only notes according to performance operation by a user but also automatically generated additional notes.

Conventionally, an electronic musical user input, such as an electronic keyboard has pre-programmed pitches associated with each key. These pre-programmed pitches correspond to the pitches from their acoustic counterparts. While some methods do exist of remapping the keys in such a way that a user cannot make a so called ‘bad’ sound by playing a wrong 5 not, there is little freedom in the selection of the ‘good’ notes. Therefore, there is herein provided a method of adjusting the complexity of a chord which therein determines the actual set of pitches which can be assigned to a user input device in order to increase the flexibility of remapping systems.

A musical instrument with an improved interface for playing the instrument is provided. The musical instrument may be configured with a musical scale and a key. An input interface of the musical instrument may be configured based on the scale and key to allow a player of the instrument to easily play multiple collections of notes, or chords, in a simplified manner. For example, the improved interface allows a user to play a number of chords or other collection of notes without having to depress or engage a number of sound actuators at different locations along instrument.

The present invention aims to change contents of an automatic accompaniment in accordance with a pitch range of a key that a user plays. The electronic musical instrument includes operated keys and a processor. The processor acquires the number of operated keys for each pitch range in accordance with the operation of the keyboard and instructs to switch an automatic accompaniment pattern accompaniment sounds to be emitted in accordance with the acquired number of operated keys for each pitch range.

An electronic musical instrument includes a plurality of performance elements that specify pitch data; a sound source that produces musical sounds; and a processor configured to perform the following: when a user performance of the plurality of performance elements satisfies a prescribed condition, instructing the sound source to produce automatic arpeggio playing sounds corresponding to pitch data specified by the user performance; and when the user performance of the plurality of performance elements does not satisfy the prescribed condition, instructing the sound source to produce a sound of a pitch data specified by the user performance without producing the automatic arpeggio playing sound.

A music based video game provides a user directed sound generation feature. In some embodiments, the user is provided a video game controller simulating a musical instrument, which the user may operate similarly to its real musical instrument counterpart. A free play feature is provided for users to operate the video game controller, where a processor of a video game console receives input signals from the video game controller and outputs audio samples based on the received input signals. During the free play feature, multiple suggestions as to how to operate the video game controller are simultaneously provided to give users some guidance as to what to play using the video game controller.
