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.

Electronic device, data usage method, and recording medium

An electronic musical instrument, method for a musical sound generation process and a non-transitory computer readable medium that stores an electronic musical instrument program are provided. The program causes a computer provided with a storage part to execute a musical sound generation process using sound data. The program causes the computer to execute: acquiring, from the storage part, first sound data and first user identification information indicating a user who has acquired the first sound data from a distribution server; acquiring second user identification information indicating a user who causes the musical sound generation process to be executed using the first sound data; determining whether or not the first user identification information matches the second user identification information; and inhibiting execution of the musical sound generation process using the first sound data in a case when the first user identification information does not match the second user identification information.

Non-transitory computer readable medium storing electronic musical instrument program, method for musical sound generation process and electronic musical instrument

The disclosure provides a server, an electronic device, a server communication method, a device communication method, and a communication system. In loading of a communication system, in the case where an identifier of a timbre data and an instruction for loading the timbre data are transmitted from a mobile terminal to a server, the server acquires the timbre data corresponding to the identifier of the timbre data from a timbre DB, and transmits the timbre data together with the received instruction to a communication device (electronic musical instrument). In the electronic musical instrument, the received timbre data is stored to a work memory in response to the instruction received from the server.
