Abstract: An electronic device and a data usage method are provided. An electronic musical instrument confirms whether respective sound data stored in a timbre memory or a wave memory can be used or cannot be used based on management information acquired from a server. A sound data determined to be usable in the management information is validated so that it can be used for loading or writing. On the other hand, a sound data determined to be unusable in the management information is invalidated so that it cannot be used.

Abstract: A communication system including a communication device, a terminal configured to be able to communicate with the communication device, and a server is provided. The communication device includes a request transmission part transmitting to the terminal a request for connection information for connecting to the server, a connection information reception part receiving from the terminal the connection information requested by the request transmission part, and a connection part communicably connecting to the server by using the connection information received by the connection information reception part.

Abstract: A communication system including a communication device, an electronic device, and a server is provided. The communication device includes an authorization information request part transmitting a request for authorization information, an authorization information reception part receiving the authorization information, a first data request information reception part receiving data request information, a data request information transmission part transmitting the received data request information, a data reception part receiving data, and a first data transmission part transmitting the received data.

Abstract: A communication system including a terminal, an electronic device, and a server is provided. The terminal includes a login part logging in to the server, an identifier reception part receiving a device identifier corresponding to a user who has logged in, and a terminal instruction transmission part transmitting to the server the device identifier received by the identifier reception part and an instruction for the electronic device.

Abstract: A communication device is provided. The communication device includes a connection instruction acquisition part acquiring a connection instruction from a user, a first communication establishment part establishing a first communication being communication with a terminal in response to acquisition of the connection instruction by the connection instruction acquisition part, a first connection information reception part receiving connection information for connecting to a server from the terminal via the first communication established by the first communication establishment part, and a second communication establishment part establishing a second communication being communication with the server by using the connection information received by the first connection information reception part.

Abstract: Systems and methods are generally described for generation and transmission of musical performance data. In some examples, the musical input device may generate a first command encoding a first musical event. In various further examples, the musical input device may generate a first message corresponding to the first command, the first message encoding a first acoustic attribute type of the first musical event. In some examples, the musical input device may generate a second message corresponding to the first command, the second message encoding a second acoustic attribute type of the first musical event. In various examples, the musical input device may generate timestamp data denoting a time of an occurrence of the first musical event. In some examples, the musical input device may send the timestamp data, the first command, the first message and the second message to a computing device.

Abstract: A storage medium storing a device driver is a storage medium storing a device driver executed by a computer to control communication between the computer and a peripheral device connected to the computer, and a process for matching a first characteristic and a second characteristic is executed by the device driver, with respect to information transmitted and received between the application software and the peripheral device, on the basis of first information and second information acquired from the peripheral device.
