Abstract
An electronic musical instrument is equipped with manual operators such as switches and controls arranged on an operation panel and keys of a keyboard as well as a display and a tone generator. It is characterized by automatically running demonstration programs when it is supplied with electric power but is left unattended at a store or in an exhibition area. The demonstration programs are started after a lapse of a predetermined time or more under prescribed conditions where none of the manual operators is operated by a user, no tone-generation instruction is issued with respect to automatic performance being played by internal functions, and no tone-generation instruction is issued with respect to external performance data being supplied by means of a communication interface. Under each of those conditions, the electronic musical instrument automatically runs a display demonstration program for displaying preset images on a screen of the display and/or a sound demonstration program for generating preset sounds. Specifically, the display automatically shows specifications, system configurations and messages with regard to the electronic musical instrument. In addition, the tone generator automatically generates automatic performance sounds or vocalized sounds of voice guidance to overall operation of the electronic musical instrument. Thus, it is possible to attract interests of visitors and customers at stores or exhibition areas.
