The present invention provides a method and apparatus for controlling a light-emitting device of a digital keyboard musical instrument. The method includes: detecting a touch action generated by a user upon a key of the digital keyboard musical instrument and generating a touch signal, by a sensor placed underneath the key, and transmitting the touch signal to a processor, wherein the touch signal comprises the magnitude information of the touch action; receiving the touch signal and generating a corresponding control signal in accordance with the magnitude information of the touch signal, by the processor; and actuating the light-emitting device to produce a light-emitting effect in accordance with the control signal by the processor. Since the detection of the touch action upon the key by the sensors is accurate enough to capture all details of the complete key-touching action, the light-emitting effect produced based on this more detailed detection of the touch action is more exquisite and accurate.

Embodiments of the present disclosure can provide systems, methods, and computer-readable medium for implementing user interfaces for interacting with a virtual instrument. For example, first touch input indicating a string location of a plurality of string locations within the note selection area. Audio output corresponding to the sting location may be presented on a speaker based at least in part on the first touch input. Second touch input corresponding to an ornamental interface element of the user interface may be received. In response to the first and second touch input, a series of two or more audio outputs may be presented on the speaker according to a predetermined pattern.

An ergonomic, portable, electronic, string-like instrument that utilizes a string-like interface. The string-like interface is tactile for sightless playability and capable of advanced input such as force and pressure sensitivity. The string-like interface functions to select a note, trigger a selected note, select and play a note on the instrument or an external peripheral. The instrument is played using the techniques of multiple stringed instruments and the ergonomics allow the user to hold and handle the device consistent with playing techniques familiar to musicians of multiple instruments. It is internally or externally powered and connects directly to industry-standard musical hardware such as MIDI devices, amplifiers and multi-track recorders.

A control device, a musical tone generation method, and a musical tone generation program capable of realizing fine change in pitch are provided.

In a synthesizer 1, when a tone generation mode is string pitch bend, pitch bend is set in an acquired MIDI message MM, and when a string number S of the MIDI message MM is generating a tone and a key-off flag is ON, a pitch of only a tone of the string number S is changed by a pitch change amount PB set in the MIDI message MM. This makes it possible to make fine pitch change in which strings of which pitches are changed on the basis of the pitch change amount PB and strings of which pitches are not changed are both included.

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.

Notwithstanding practical limitations imposed by mobile device platforms and applications, truly captivating musical instruments may be synthesized in ways that allow musically expressive performances to be captured and rendered in real-time. Synthetic musical instruments that provide a game, grading or instructional mode are described in which one or more qualities of a user's performance are assessed relative to a musical score. By providing a range of modes (from score-assisted to fully user-expressive), user interactions with synthetic musical instruments are made more engaging and tend to capture user interest over generally longer periods of time. Synthetic musical instruments are described in which force dynamics of user gestures (such as finger contact forces applied to a multi-touch sensitive display or surface and/or the temporal extent and applied pressure of sustained contact thereon) are captured and drive the digital synthesis in ways that enhance expressiveness of user performances.

According to one aspect of the present invention, there is provided an audio system. The audio system includes a user computer to output a note; a musical instrument unit to transmit a first electrical signal to the user computer, and a user operation recognition device attached to or disposed at a specific part of the musical instrument unit to transmit a second electrical signal to the user computer. The user operation recognition device is to change or adjust a note of the musical instrument unit on the basis of a touch applied to the user operation recognition device. The user operation recognition device includes a substrate, and at least one unit cell including a first partial electrode formed along a first pattern on the substrate and a second partial electrode formed along a second pattern on the substrate.

Provided are an electronic musical instrument, a processing execution method, and a processing execution program capable of quickly performing registration to a key group based on key depression from key depression, and special processing based on keys registered to the key group. In a case where the depressed position of a key 2a is between a determination start position D3 and a determination end position D4, the key 2a is registered to a key group. Registration of the key 2a to the key group can be quickly determined by only confirming the depressed position of the key 2a. In a case where a key 2a registered to the key group reaches a sound generation start position Ds, and the registration number in the key group at that point is two or more, a musical note with a special tone based on that key 2a is generated. Therefore, the time lag from the registration of the key 2a to the key group to the start of sound generation based on the key 2a registered to the key group is minimized, making it possible to quickly register a key 2a to the key group based on key depression from key depression, and generate a musical note based on the key 2a registered to the key group.
