Abstract: The disclosure provides a wireless communication device, an electronic device, and a wireless communication method. A wireless communication device is connected to an electronic musical instrument and transmits and receives MIDI data input to and output from the electronic musical instrument to and from other wireless communication devices paired through wireless communication at a predetermined communication interval, the pair is formed with each of a plurality of the other wireless communication devices. The wireless communication device includes a communication interval setting part configured to set a communication interval of each pair to a different time interval; and a communication interval transmission part configured to transmit the communication intervals set by the communication interval setting part to the corresponding other wireless communication devices.

Abstract: A wireless communication device and a wireless communication method are provided. When a master mode is set in a mode memory, a mode setting notification is transmitted to a different wireless communication device. When a mode setting permission notification for the mode setting notification is received from the different wireless communication device, the master mode is settled as a communication mode, and the master mode is set in the mode memory. When a slave mode is set in the mode memory and when a mode setting notification is received from the different wireless communication device, the slave mode is settled as the communication mode, the slave mode is set in the mode memory, and a mode setting permission notification is transmitted to the different wireless communication device. Thus, the communication mode can be automatically set in a pair of wireless communication devices.

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: 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.
