Music game equipment and electronic music equipment and its computer programme

一种音乐游戏设备，其按照乐曲信息显示一个给定游戏屏幕。该屏幕包括按照该乐曲信息待操作的演奏操作器的图像。该游戏设备以比该特定演奏操作器应操作的定时更早的定时，将用于提供一个指示待操作的特定操作器(键)的指导信息，传输到一个包括演奏操作器比如键的电子音乐设备。该音乐设备提供显示器，以按照接收的指导信息向该用户指示该待操作的特定操作器。按照音符信息而非该指导信息，该游戏设备可控制该音乐设备以禁止实现该演奏指导。而且，该游戏设备可控制该音乐设备从而防止代表已操作的演奏操作器的操作相关信息被提供给一个音调产生器。 A music game apparatus (PC) displays a given game screen according to music piece information. The game screen includes images of performance operators to be operated according to the music piece information. The game apparatus transmits, to an electronic musical apparatus (10) including performance operators, e.g. keys, guide information for providing a performance guide to indicate a particular operator (key) to be operated at timing earlier than timing at which the particular operator should be operated. The musical apparatus provides display to indicate to the user the particular operator to be operated according to the received guide information. The game apparatus may control the musical apparatus to prohibit the performance guide from being carried out according to note information other than the guide information. Further, the game apparatus may control the music apparatus so as to prohibit operation related information representing the operated performance operator from being supplied to a tone generator.
