The header is composed of various data (song code, song name, genre, release date, performance time, etc.) relating to this song data. Of these, the genre data is used as data for selecting a background image. For example, if the genre is "Enka of winter", the scene of the snow country is selected, and if the genre is "pops", the foreign image is selected.

The musical tone track is composed of a plurality of part tracks such as a guide melody track, various musical instrument tracks, and a rhythm track. Each track is composed of event data and duration data indicating a time interval between the event data. When performing automatic performance C
When the PU 30 reads the event data from the track, it outputs this to the sound source device 39. When the duration data is read, it is counted down according to the tempo clock, and when the count value becomes 0, the next data is read.

The lyrics track is a sequence track in which the lyrics displayed on the monitor 21 are stored, and is composed of duration display data (event data) and duration data indicating a time interval between consecutive event data. Note that the lyrics track data is not general-purpose MIDI data, but in order to unify the implementation and facilitate the work process, all audio tracks and effect tracks including this track are described in MIDI format. . The lyrics display data includes character data of one line of lyrics, display time of the lyrics, and wipe sequence data. The wipe sequence data is sequence data for changing the display color of the lyrics in accordance with the progress of the song.

The voice track is sequence data for controlling the generation of human voice such as back chorus or harmony singing which is difficult to synthesize in the sound source section, and is the ADP alarm screen data stored in the voice data section. Event data that controls generation timing and the like is written together with duration data.

The effect track is an effect device D.
It is composed of event data and duration data for controlling the function of SP42. The event data is data instructing what kind of effect is applied to the musical tone signal and to what extent.

FIG. 3C is a diagram showing the structure of alarm screen data. The alarm screen data has the same basic structure as the music data, but the musical sound track and the effect track are omitted because no musical sound is involved. Further, the alarm screen track corresponds to the lyrics track of the music data, and the announcement track corresponds to the voice track. The header is
It is composed of various data relating to the alarm screen data (alarm screen code, warning content, registration date, projection time, etc.).

The alarm screen track corresponds to the lyrics track of the music data as described above, and stores the alarm screen displayed on the monitor 21. As shown in FIG. 4, the alarm screen is composed of a message indicating that evacuation is required and a diagram showing an evacuation route, etc., but these are both coded and written in the alarm screen track. When the warning screen has several screens, it is stored as sequence data.

The voice data section is composed of data of a word for notifying that an emergency has occurred and a word for guiding the evacuation, and the announcement track controls the utterance timing.

FIG. 5 is a flow chart showing the operation of the karaoke apparatus 2. This operation shows an interrupt operation when an emergency signal is input from the host device 1. The karaoke device 2 normally executes the performance operation of the music data in response to the request from the customer, but when the emergency signal is input from the host device 1, the karaoke device 2 executes the following operation as the highest interrupt operation. First, it is determined whether or not music data is currently being played (s1). If the music data is being played, the performance is stopped (s2). This stopping operation is performed by the sound source device 3
9 includes the transmission of an all-note-off signal to 9 and the transmission of a STOP signal to the LD changer 44.
Next, the alarm screen data to be displayed is determined from the content of the sent emergency signal (s3). The storage address of the determined alarm screen data is searched (s4), this alarm screen data is taken into the execution data storage area of the RAM 32 (s5), and the same reproduction operation as that of normal music data is started (s6). As a result, an indication of an emergency and a guidance screen for evacuation or the like are displayed on the monitor 21, and an announcement prompting evacuation is played from the speaker 22.
However, since the alarm screen data does not have a musical sound track and an effect track, the sound source device 39 and the DSP 42 are not driven, and data for selecting a background image such as genre data is not included in the header. The changer 44 is also not driven.

As described above, when an emergency occurs,
Since the karaoke performance can be stopped and the monitor 21 and the speaker 22 can be used to notify the user of the emergency, it is possible to facilitate the evacuation of the customer. Also, by making the emergency screen data almost the same as the music data,
No special configuration is required to reproduce the emergency screen data, and the alarm can be issued by the function provided in the karaoke apparatus 2 conventionally.

In the above embodiment, the alarm screen data is incorporated in the same structure as the music data, but the LD incorporated in the LD changer 44 may be provided with an alarm screen chapter. In addition, the BGM data (music track,
(Effect track) may be included.
