Communication system, terminal, server and communication method

A terminal configured to communicate with a server, comprising:

• a first hardware processor configured to execute:
• a login part that logs in to the server;
• an identifier reception part that receives from the server a device identifier being an identifier of an electronic device corresponding to a user who has logged in by the login part;
• and
• a terminal instruction transmission part that transmits to the server the device identifier received by the identifier reception part and an instruction for the electronic device, wherein the server transmits the instruction received from the terminal instruction transmission part to the electronic device corresponding to the device identifier received from the terminal instruction transmission part, wherein
• the electronic device is an electronic musical instrument;
• and
• the electronic musical instrument is configured to acquire timbre data used for sound production by the electronic musical instrument from the server in response to the instruction from the user.

A server configured to communicate with an electronic device and a terminal, comprising:

• a memory comprising an identifier storage part that stores a user identifier being an identifier of a user in association with a device identifier being an identifier of the electronic device corresponding to the user;
• and
• a second hardware processor configured to execute:
• an identifier transmission part that acquires from the identifier storage part the device identifier corresponding to the user identifier of the user of the terminal that has logged in and transmits the device identifier to the terminal that has logged in;
• a first server instruction reception part that receives from the terminal the device identifier and an instruction for the electronic device;
• and
• a server instruction transmission part that transmits the instruction received by the first server instruction reception part to the electronic device corresponding to the device identifier received by the first server instruction reception part, wherein
• the electronic device is an electronic musical instrument;
• and
• the electronic musical instrument is configured to acquire timbre data used for sound production by the electronic musical instrument from the server in response to the instruction from the user.

A communication method by a terminal, an electronic device and a server, comprising:

• storing on the server a user identifier being an identifier of a user in association with a device identifier being an identifier of the electronic device corresponding to the user;
• in the terminal, logging in to the server;
• in the server, acquiring the device identifier corresponding to the user identifier of the terminal that has logged in and transmitting the device identifier to the terminal that has logged in;
• in the terminal, transmitting to the server the transmitted device identifier and an instruction for the electronic device;
• and
• in the server, transmitting the transmitted instruction to the electronic device corresponding to the transmitted device identifier, wherein
• the electronic device is an electronic musical instrument;
• and
• the electronic musical instrument is configured to acquire timbre data used for sound production by the electronic musical instrument from the server in response to the instruction from the user.
