PURPOSE:To identify easily the music number set for indication of playback as well as to identify easily a music number under playback from other music numbers, by displaying in regular order the music numbers indicated for playback and having optically different displays between the number of music under playback and the numbers of other music not under playback. CONSTITUTION:A designated music number counter 102 counts the designating frequencies every time a music number is designated by a digit key switch 101. A music number memory means 103 stores successively the designated music numbers. These memory contents are successively displayed ever time a music number is designated to the means 103. While a display switch means 115 applies an optical change including a change in color, the flickering, etc. to the display of a display means 104 for designated number of music under playback by means of a signal obtained while the designated music is played. Thus the number of a designated music under playing is indicated. At the same time, the output of a playing music pointer 114 is compared with the counted value of the counter 102 through a comparing means 116. Then the generation of output is stopped when the output of the pointer 114 exceeds the counted value of the counter 102. |
