Abstract: 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.
