<p>In an electronic music apparatus system, a unique musical instrument ID is stored in an electronic musical instrument (10A,10B,10C) by means of a plant computer before shipment thereof. After purchase of the electronic musical instrument (10A,10B,10C), a user transmits the stored musical instrument ID to a management computer (22) via a network (20) without use of any intermediate device or by use of a user computer (11) or a user portable communication terminal (12) and performs user registration. By use of the musical instrument ID, the user downloads a program or content item suitable for the electronic musical instrument from a program distribution computer (24) or a contents distribution computer (23) via the network (20). <IMAGE></p> |
