Abstract: In a server 70, usage counts of tone data of an electronic musical instrument 30, such as load counts of times that the tone data are loaded in the electronic musical instrument 30 are stored for each tone data and each user H utilizing the electronic musical instrument 30. When a recommendation information request is received from a portable terminal 50, the server 70 obtains a similar user similar to a request user included in the recommendation information request from the stored usage counts. Tone data to be recorded in the recommendation information are obtained from the usage count of each tone data of the request and the usage count of each tone data of the similar user, and the recommendation information is generated from the obtained tone data. Accordingly, the recommendation information generated by the user 70 can conform to the preference of the request user.

Abstract: Provided is a musical instrument controller capable of accurately controlling a musical sound parameter. This musical instrument controller includes: a reception means for receiving, from a musical performance device, a sound emission start signal transmitted on the basis of a musical performance operation; a sensor for detecting an amount of displacement from a reference position; and a control means for generating a control signal on the basis of the amount of displacement from the reference position and transmitting the control signal to a sound generation device. The control means sets the reference position on the basis of the sound emission start signal received from the musical performance device.

Abstract: Provided are an electric musical instrument system and a control method thereof. The electric musical instrument system includes a musical sound transmitting means and a musical sound receiving means having a first mode and a second mode that consumes less electric power than the first mode. The musical sound transmitting means has a detecting means for detecting rocking of a musical instrument and a transmitting means that transmits an audio signal emitted from the musical instrument to the musical sound receiving means in the first mode and transmits, when detecting rocking of the musical instruments, detected information to the musical sound receiving means in the second mode. The musical sound receiving means has a controlling means that processes the audio signal received in the first mode and cancels the second mode and changes the mode to the first mode when the detected information is received in the second mode.

Abstract: To provide an electronic wind instrument capable of accurately detecting the amount of rotation of a transmission member. During an electronic wind instrument performance by a performer, external light (such as light from lighting) may easily shine on the upper surface side of an instrument main body. However, the light-receiving section of an optical sensor faces toward the bottom surface side of the instrument main body therefore external light from the upper surface side of the instrument main body can be prevented from reaching the light-receiving section of the optical sensor. As a result, erroneous detection of the external light by the optical sensor can be suppressed therefore the rotation amount of a transmission member can be accurately detected by the optical sensor.

Abstract: An effector mounting plate is provided, which can protect wiring when carried while enabling work on the wiring. A back surface side of a plate is covered by a back case, and wiring (not shown) can be stored in a space formed between the plate and the back case. Therefore, when the plate and the back case are used as an effect pedal or carried, an external force can be prevented from acting on the wiring. Therefore, the wiring (jack) can be prevented from falling off an effector or from being forcibly bent and broken. By removing fastening screws, the back case can be removed from the plate to open the back surface side of the plate. Therefore, work on the wiring such as work of connecting/disconnecting the wiring to/from the effector and work of checking the wiring before performance can be easily performed.

Abstract: A frame body fixed to a membrane 10 is divided into multiple long-side frame bodies 11 and a short-side frame body aligned in a peripheral direction of a frame 3. Tension is applied to the frame body 10 by pulling each frame body 11, 12. Accordingly, it is not necessary to make the shape of each frame body 11, 12 consistent with the frame 3 (support part 30) in a complicated polygonal shape, and the shape of each frame body 11, 12 can be formed as a linear shape. Therefore, the shape of each frame body 11, 12 hardly varies. In addition, even if the shape of each frame body 11, 12 varies, tension can be uniformly applied to the membrane 10, as it is configured that each frame body 11, 12 is pulled to apply tension to the membrane 10.

Abstract: A wireless communication device and a wireless communication method capable of curbing occurrence of latency even when performing wireless communication at predetermined time intervals are provided. MIDI data is transmitted and received by communication (B) performed through a wireless module during an intermission between communications (A) performed at predetermined time intervals through the wireless module. Accordingly, a communication speed for wireless communication is improved. Therefore, compared to a case in which wireless communication is performed by only the communication (A), MIDI data can be quickly transmitted and received, and thus occurrence of latency can be curbed.
