Provided are a control device, a control method and a control system. In a control system, a headphone and a pedal device are in communication with each other through first communication, and the pedal device and a portable terminal are in communication with each other through second communication. Accordingly, even when the headphone can be connected to only one control device, a control instruction from the pedal device can be transmitted to the headphone through the first communication, and a control instruction from the portable terminal can be transmitted to the headphone through the second communication and the first communication.

A pedal device receives a connection signal transmitted from headphone to establish first communication that is communication with the headphone. Then, in a case where the first communication has been established, the pedal device transmits the connection signal including information indicating that communication with the headphone has been established. By receiving the connection signal from the pedal device, a portable terminal establishes second communication that is communication with the pedal device. In a case where the received connection signal includes information that the communication with the headphone has been established, the portable terminal may determine that communication establishment between the pedal device and the headphone has been completed.

An electronic device has setting data in binary format formulated according to a specific format suitable to realize a function in the device. In order to share the setting data in binary format with another device, the electronic device converts the setting data in binary format to setting data in text format and transmits (uploads) a set of text data containing the converted setting data in text format to a network communication service provided on a server through a communication network. The network communication service may be a conventional communication service of a web site capable of handling text data. Another electronic device can access the network communication service through communication network, receive (download) the set of text data, and then reversely convert the setting data in text format contained the received set of text data to the original setting data in binary format.

A musical device between one or more Musical Instrument Digital Interface (MIDI) controllers and one or more musical instruments comprises a housing and a plurality of potentiometers on a surface of the housing. A method of mapping music messages using a musical device is provided. The method includes defining a preset value corresponding to a frequency to be received within a MIDI message. Once a MIDI message having the frequency is received by the device, the device uses the data of the MIDI message and the preset value to create a new output MIDI message. The new output message is then transmitted to a sound module for producing a sound that differs from the sound that would have been produced from the MIDI message, had it been received.

A musical instrument digital interface (MIDI) controller is provided. It has a housing having a hollow interior portion, a first audio jack and a second audio jack positioned on the housing, wherein the first audio jack is configured to accept a first audio signal from an electronic music instrument, and wherein the second audio jack is configured to accept a second audio signal from a microphone, a conversion module configured to receive the first signal from the first audio jack and the second signal from the second audio jack, wherein the conversion module is configured to transform the first signal into an outgoing digital signal and retain the second signal in a database and an output module configured to utilize the outgoing digital signal and the retained second signal from the database, and output both signals as a dual signal of audio and digital outputs during a user performance.

A sound control device includes a selector, a sound signal generator, a switcher, and a controller. The selector is configured to select, based on a user operation, one piece of setting information among a plurality of pieces of setting information including at least one timbre group and one effect setting group. The sound signal generator is configured to generate a sound signal based on performance information and the selected setting information. The switcher configured to switch between a hold-enabled state and a hold-disabled state based on a user operation. The controller configured to control the sound signal generator to generate the sound signal such that in the hold-enabled state, even if the selection of the setting information is switched by the selector, at least the effect setting is maintained.

Provided is a control device which controls an electronic musical instrument, comprising: an acquisition means which understands the intention of an utterance of a user on the basis of the utterance, and acquires from a dialogue engine that generates first data in which the intention is stated, the first data generated in response to the utterance; a storage means which stores conversion data in which the first data and a control command for controlling the electronic musical instrument are associated with each other; and a conversion means which generates, on the basis of the acquired first data and the conversion data, second data suitable for a control interface of the electronic musical instrument to be controlled, and transmits the second data to the electronic musical instrument.

A method for interfacing tones with a computer enables a music device to emulate the functions of a computer keyboard. The method includes receiving a digital signal representing one or more note events and identifying a group of concurrent notes from the one or more note events, wherein the one or more note events each have a pitch, a velocity and an initiation. In accordance with a pitch class of a base note of the group of notes and intervals computed between pitch classes of the notes of the group as ordered by the pitch of the note events, the group of notes are translated into a computer input signal representative of one or more keystrokes on a computer keyboard and the computer input signal is sent to a computer for output or further processing.

A microtonal musical instrument interface device between one or more Musical Instrument Digital Interface (MIDI) controllers and one or more musical instruments comprises a housing and a plurality of potentiometers on a surface of the housing. The potentiometers comprise twelve tuning potentiometers constructed and arranged to correspond to notes of a musical scale, each tuning knob for tuning one of the notes; an offset potentiometer for globally tuning all of the notes by a same amount; and a range potentiometer for setting a maximum tuning range of the tuning potentiometers. A microprocessor in the housing modifies a MIDI data stream received from the one or more MIDI controllers for output to the one or more musical instruments according to a position of the potentiometers.

To assist a human player in performing a plurality of foot operators (pedal keys) operable with a human player's foot, a foot operator image indicative of the foot operators is displayed on a display screen. Model performance data including at least information indicative of a rhythm and a pitch of a foot performance part to be performed by use of the foot operators is acquired, and a particular foot operator corresponding to the pitch of the foot performance part included in the acquired model performance data is visually designated. At the same time, based on rhythm information for the foot performance part, a rhythm of a sound corresponding to the particular foot operator is presented. The presentation of the rhythm is performed by presenting a sound generation timing and a time length of the sound, and a suitable marker indicative of a performance progression may be additionally displayed.
