Next, FIG. 8 shows a flowchart of a reproduction start switch process for instructing reproduction of the selected music data operated on the main screen. When the reproduction start switch is operated, the lyrics data in the song data (song data) is searched in step S31. If it is found in step S32 that the song data contains lyrics data, the flag is set to be a lyrics presence flag. If the lyrics data cannot be searched, the flag is set to a no lyrics flag. Set so that Next, the routine proceeds to step S33, where it is determined whether or not the state of the function switch F3 is turned ON and the lyrics display mode is instructed. Here, if the function switch F3 is ON, it is determined as YES and the process proceeds to step S34, and it is determined from the flag set in step S32 whether or not there is lyrics data in the song data. Then, if the flag is set to the lyrics presence flag and there is lyrics data in the song data, the screen is switched so that the lyrics are displayed on the screen of the display 11-1. Will be started.

If it is determined in step S33 that the lyrics display mode has not been turned on, the process proceeds to step S33.
The process branches to 37 to determine whether or not the piano roll notation display mode is ON. If it is determined that the switch is ON, the process proceeds to step S38, where the screen is switched to the display screen of the piano roll score, and the reproduction process of the song data is started in step S36. Further, step S
If it is determined in 37 that the piano roll notation display mode is not turned on, the process branches to step S39, where it is determined whether or not the score display mode is turned on. If it is determined that the score display mode is ON, the process proceeds to step S40, where the screen is switched to the score display screen, and the reproduction process of the song data is started in step S36. Further, if it is determined in step S39 that the score display mode has not been turned ON, the function switch F4 has been turned OFF, so that the currently displayed main screen remains unchanged and the process proceeds to step S36. As a result, the reproduction process of the song data is started.

The song data includes performance data,
Lyric data and chord data are mixed. The song data is stored in the external storage device 5 or the like, for example, in the form of a standard MIDI file, and the lyrics data and chord data are stored as meta events. In the standard MIDI file, the identification code of the lyrics data (the first byte of the event is "FF" and the second byte is "05") is defined. The presence or absence can be determined. In step S31 described above, lyrics data is searched using such a technique.

Next, FIG. 9 is a flowchart of the song data reproduction process. The reproduction process is started when the timer 4 interrupts the CPU 1 at predetermined time intervals according to the tempo, and the song data is reproduced. Display control is executed in accordance with the progress of reproduction and song data. The period at which an interrupt occurs is, for example, about 5 ms. When a timer interrupt is generated from the timer 4 to the CPU 1, the reproduction process is started, and an event that has reached the timing to be processed in step S41 is performed.

Next, in step S42, it is determined whether or not the state of the function switch F3 is turned ON and the lyrics display mode is instructed. Here, if the function switch F3 is ON, it is determined as YES and the process proceeds to step S43, and it is determined from the flag set in the reproduction start switch process whether or not there is lyrics data in the song data. Then, if the flag is set to the lyrics presence flag and the lyrics data exists in the song data, the lyrics display processing is performed so that the lyrics are displayed on the screen of the display 11-1, and the process returns.

In the lyrics display processing, display processing is performed so that the lyrics are displayed on the screen for each page using the line feed code and the page break code embedded in the lyrics data. Further, the displayed lyrics may be wiped according to the progress of the music. If it is determined in step S42 that the lyrics display mode is not turned on, the process branches to step S45 to determine whether the piano roll notation display mode is turned on. And O
If it is determined that the answer is N, the process proceeds to step S46, where the display process of the piano roll music is performed, and the process returns. In this piano roll notation display process, the piano roll notation is scrolled according to the progress of the song,
A display process is performed so that the sounding key is displayed on the keyboard.

If it is determined in step S45 that the piano roll notation display mode is not turned on,
The process branches to step S47, where it is determined whether the score display mode is ON. If it is determined that the score display mode is ON, the process proceeds to step S48, where the score display process is performed and the process returns. In this musical score display processing, a musical score of one page (for example, 12 measures) is displayed on the screen, and a display processing of displaying the performance position is performed. Further, step S4
If it is determined in step 7 that the score display mode is not turned on, the function switch F4 is turned off, so that the main screen is left as it is and the process returns.

The display area of the switch function name and the setting state in the display control device of the present invention is not limited to the lower part of the area where the lyrics, the piano roll notation or the score is displayed, but may also be the upper part or the left and right vertical direction. Good. The display at this time is not limited to the LCD, but may be a fluorescent display tube, a CRT, a plasma display, or the like.
