Abstract:
1. An electronic music apparatus comprising: a sound generator for generating a music sound signal according to music data, which is voice data configured for controlling a timbre of the music sound signal; a display device for displaying information associated with the music data; a storage medium that stores a plurality of music data files, each file being written with the music data for generating the music sound signal, the music data file having a file name containing a name of the music data and an icon ID identifying an icon; an information retention section that retains file information, which is created based on the file names and storage locations of the plurality of the music data files, the file information containing the name and the icon ID of each music data file based on the file name, and containing the storage location of each music data file; a reading command section that issues a command of reading a target music data file among the plurality of the music data files from the storage medium according to the file information; a display control section that generates display data representing the name of the music data and an image of the icon based on the icon ID provided by the file information of the target music data file and that controls the display device, when the target music data file is successfully read, to display the name and the icon associated with the successfully read target music data file based on the display data, and that controls the display device, when the target music data file is unsuccessfully read, to display the name and the icon associated with the unsuccessfully read target music data file differently from the name and the icon associated with the successfully read target music data file; and selection switches provided in correspondence to the names and the icons of the music data files displayed on the display device, the selection switches including one selection switch corresponding to a music data file successfully read from the storage medium and another selection switch corresponding to a music data file unsuccessfully read from the storage medium, wherein when the target music data file is unsuccessfully read, the display control section modifies the display data, while maintaining the file information, to change the name associated with the unsuccessfully read target music data file to a new name containing the original name associated with the target music data file plus at least the characters “not found” to distinguish from the name associated with the successfully read target music data file, and to change the icon associated with the unsuccessfully read target music data file to a predetermined icon that is different from the icon associated with the successfully read target music data file and that indicates that the target music data file is not found, and wherein the display control section controls the display device to display an overview that displays the names and the icons associated with the plurality of the music data files, including the new name and the icon associated with each unsuccessfully read music data file, in a same display window of the display device such that the new name and the icon associated with each unsuccessfully read music data file is readily recognizable, wherein when the one selection switch is operated, voice data contained in the music data file corresponding to the one selection switch is set to the sound generator for controlling the timbre of the music sound signal, and wherein when the another selection switch is operated, no music data file is selected and the timbre of the music sound signal generated by the sound generator is not changed.
