The operation of the circuit shown in FIG. 12 will be described with reference to the flow chart shown in FIG. As described above, the system CPU 50 reads the file management information recorded in a predetermined area of the disc via the system processor 54 in order to obtain all the information necessary for performance including sequence use. The read information is stored in the system ROM & RAM 52 until the power of the reproducing apparatus is cut off (step S1).

In reproducing the disc, first, the sequence use (SCAT) is analyzed to determine whether or not it is the karaoke mode. If the mode is other than the karaoke mode, the operation of the disk device is set according to the mode (steps S2 and S3).

If in karaoke mode,
The display section 4A indicates that it is in the karaoke mode by using an LED or the like.
Is displayed and the start point of the first song is searched,
The pose state is set at that position (steps S3 and S4). Here, the screens as shown in FIGS. 14A, 14B, and 14C can be displayed on the monitor 6 by adjusting the key input unit 4B.
That is, when the microphone volume is adjusted while looking at the adjustment screen as shown in FIG. 14A, the adjustment command is given to the microphone voice input unit 120 via the key input unit 4B, and the amplification factor of the input microphone voice signal changes. FIG. 14B
If you adjust the echo while looking at the adjustment screen as shown in,
The adjustment command is given to the reverberation effect control means 129 via the key input unit 4B, and the echo of the input microphone audio signal is changed. Further, as shown in FIG. 14C, when the key control corresponding to the pitch of the sound is adjusted, the adjustment command is transmitted via the key input unit 4B to the voice tone control unit 1.
26, the tone of the main audio signal is changed. Further, as shown in FIGS. 14D and 14E, when the level of the sub-audio and the left and right balance thereof are adjusted while looking at the adjustment screen, the adjustment command causes the sub-audio signal amplitude adjustment unit 124 and the sub-audio signal to be input via the key input unit 4B. It is given to the L / R balance adjustment unit 125, and the reproduced voice level of the sub voice and the left and right balance thereof are adjusted. If the adjustment is incorrect, as shown in FIG. 14F, a reset command is issued to the microphone voice input unit 120, the reverberation effect control unit 129, and the voice tone control unit 1 according to the screen for canceling the adjustment and the release.
26, the sub audio signal amplitude adjusting unit 124, and the sub audio signal L /

26, the sub audio signal amplitude adjusting unit 124, and the sub audio signal L /
The R balance adjustment unit 125 is returned to the standard state before the adjustment. If such an adjustment has been made, after this adjustment, it is confirmed whether or not there is menu information, especially the menu of all songs (step S5). If there is menu information, the menu screen shows all songs. It is confirmed whether or not to display the menu (step S6). When displaying the menus of all the songs (step S7), the menus are displayed, and the performance song name is selected from the display (step S9). Here, it is clear that the menu of all the songs may be composed of the main menu and a plurality of sub-menus as described above. Here, if the performance song name is not selected, step S is performed again.
It will be returned to 5. If there is no menu in step S5 or if the menu is not displayed in step S6, the song name menu is not displayed and the song is selected by specifying the code in the song list (step S8). , Step S9). As described above, the selection of the musical piece to be played corresponds to the selection of the program in a certain sequence, and the head cell in the program is searched by the designation of this program. In this way, interactive karaoke operation is possible in the paused state. When the performance song is selected, it is confirmed whether or not the performance start key is pressed (step S10). If the performance start key is not pressed, the process returns to step S5. When the performance start key is pressed, the designated music is searched and the performance is started (step S11). After that, when the performance ends, the pause mode is maintained at the start position of the next song and the process returns to step S5 (step S1).
3). The end of the performance is the end of the program selected as described above, and corresponds to the reproduction of the cell data in the program. When the performance is finished, the adjustment command already set before the performance is reset unless the hold for holding the adjustment operation is pressed in the key operation portion 4B. That is, a reset command is issued from the key input unit 4B at the end of the performance,
The reset command is the microphone voice input unit 120, the reverberation effect control unit 129, the voice tone control unit 126, the sub voice signal amplitude adjustment unit 124, and the sub voice signal L / R balance adjustment unit 1.
25, the microphone voice input unit 120, the reverberation effect control unit 129, the voice tone control unit 126, the sub voice signal amplitude adjusting unit 124, and the sub voice signal L / R balance adjusting unit 125 are returned to the standard state before the adjustment. To be done. This reset command may be generated when the title of the song to be sung next is selected on the next menu screen, or it is maintained as it is during the song of the selected genre,
A reset command may be issued when the genre changes.

If the performance has not ended, for example,
When the re-sing key is pressed in the middle of the performance in hope of re-sending (step S14), the process returns to step S11. In this re-song mode, the head data cell of the program already selected is designated as a reproduction cell and the data cells are reproduced one after another. If the tone or reverberation key is pressed during the performance and the tone key or the reverberation key is pressed (step S15), the processing corresponding to the pressed key is performed and the display screen is switched, and after a predetermined time The screen is returned to the original playing screen, that is, step S12. When the sub voice level or the balance key is pressed (step 16), the processing corresponding to the pressed key is similarly performed, and the display screen is switched, and after a predetermined time, the original playing screen, That is, the process returns to step S12.

On the menu screen described above, it is possible to select not only the main voice such as the performance corresponding to the title but also the sub voice. For example, only the orchestra may be purely used as the main voice corresponding to the master stream, and vocals as a model of the singing corresponding to the sub-voice may be selected as the slave stream in addition to the master stream. By such selection, it is possible to select whether to perform only karaoke or to mix vocal voices and perform with a voice guide.

Furthermore, if male vocals are assigned to L (left) and female vocals are assigned to R (right) of the vocal voice, for example, when a male sings a duet song alone, only R (right) of the vocal voice becomes the orchestra. You can mix and sing. When a female is duet alone, the male vocal of L (left) is mixed in reverse to the above.
Such a setting can be realized by selecting a slave stream from the menu screen in addition to the master stream. .

In addition to this, in the karaoke mode, it is possible to adjust the tone (key) of the audio signal of the orchestra and add a reverberation effect (echo) to the externally input sound from the microphone, and according to the operation of these keys. Microphone volume, reverberation level, tone, sub-audio level and balance, etc. are symbolized and displayed on the screen. Also, in the case of karaoke, a function that is especially required is provided so that when you want to sing again from the beginning, the re-sing function is provided. This is the beginning of the song being played immediately when the re-sing key is operated. It returns to and reproduces.
