[0026]
B. Next, the operation of the karaoke apparatus according to this embodiment will be described. This karaoke apparatus is characterized by a jump process in which the performance of the currently played music is stopped and the performance of the next music is started in accordance with an instruction from the user input during the performance of the music. Among the jump processes, the song data is a medley song (see FIG. 4A), and the medley song jump process for jumping from the song included in the medley song to the next song included in the medley song, and the song data. Is data other than the medley music (see FIG. 4B), and there is an inter-music jump process for jumping to the reserved music data, which will be described separately below.
[0027]
B-1. First, the medley song jump process will be described with reference to FIG. In this case, as a method for determining whether or not the karaoke song reserved by the user via the operation unit 7 is a medley song, the song number of the medley song is stored in the ROM 3 in advance and stored therein. There is a method for determining that the song is a medley song when a song number is input. Moreover, you may include the information which shows that it is a medley music in the header of music data.
[0028]
When the medley music is reserved by the user, the music data of the medley music reserved by the user (hereinafter referred to as medley music data) is read from the hard disk device 5 and stored in the music data reading areas 42a and 42b in the RAM 4. Written to each. That is, the same medley music data is written in each of the music data reading areas 42a and 42b. Then, the medley music data is sequentially read from the music data reading area 42a and output to the sound source device 8a. Then, based on the medley song data sequentially output from the song data reading area 42a, the tone generator 8a generates a tone signal and outputs it to the amplifier speaker 10. The musical tone signal from the sound source device 8a is amplified and then emitted from the amplifier speaker 10. In this way, the performance is started from the beginning of the medley song data (step Sa1).
[0029]
When a jump command is input from the user during the performance of this song (step Sa2), a bridge process is performed to connect the currently played song and the next song to be started (step Sa3). In the bridge processing, note-on event data at the start of the bridge processing is held for a predetermined bridge section, for example, one bar. That is, the musical sound that has been pronounced so far is pronounced as it is, and no new musical sound is produced.
[0030]
In this way, while the bridge processing is performed by the a system, the head mark of the next music included in the control information track of this medley music data is searched (step Sa4). When the performance of the music by the a system is stopped at the time when the predetermined bridge section is finished, the music data to be executed after the timing indicated by the searched head mark, that is, the music data of the next music is sequentially transmitted from the music data reading area 42b. Is output to the sound source device 8b. Then, based on the data read from the music data reading area 42b, the sound source device 8b generates a musical sound signal and outputs it to the amplifier speaker 10, and starts playing the next music by the b system (step Sa5). In this way, by performing a bridge process and continuously playing between the first song and the next song, the sound is not interrupted between the first song and the next song. .
[0031]
Here, FIG. 7 is a diagram showing the processing contents of each performance system in the medley song jump processing. As shown in the figure, when the user inputs a jump command, the bridge process is performed and the performance of the first song is stopped after the first song is stopped. If a jump command is input during the performance of this song, the same processing as step Sa2 and after is performed, the performance of the b system is stopped, and the performance of the next song of the a system is started.
[0032]
On the other hand, if a jump command is not input during performance, the performance corresponding to the medley song data is continued. That is, the jump process is not performed, and each song included in the medley song is played sequentially. In the above description, the case where the jump command is input during the performance of the first song among the medley songs has been described. However, when the jump command is input during the performance of the second and subsequent songs, The same processing from step Sa2 to step Sa5 as described above is performed.
[0033]
If the start mark of the next song cannot be searched when a jump command is input, that is, if the currently playing song is the last song included in this medley song data, the current performance is being executed. The performance by the performance system is stopped when the bridge section ends.
[0034]
In the karaoke apparatus according to the present embodiment, for example, when a song that the user does not know is played while performing a medley song, the medley song jump process described above performs the next song performance. Can be done from the beginning. Therefore, even if there is a medley song that the user does not know, the song can be skipped and the next song can be played immediately from the beginning of the song. There is no waiting for the performance to end.
[0035]
B-2. Next, the inter-music jump process will be described with reference to FIG. In the song jump process, if multiple songs (other than medley songs) are reserved for the user and a jump command is input while playing the reserved songs, the currently playing song is stopped. This is a process of starting the performance of the next reserved song from the designated portion of the song.
[0036]
First, the music data of the first song reserved for the user is read from the hard disk device 5 and written in the music data reading area 42 a of the RAM 4. Also, after the second music data reserved for the user is read from the hard disk device 5 and written to the music data reading area 42b of the RAM 4, the first music data is sent from the music data reading area 42a to the sound source device 8a. Is output. Then, based on the first song data output from the song data reading area 42a, the tone generator 8a generates a musical sound signal and outputs it to the amplifier speaker 10. In this way, the performance of the first song data is started (step Sb1).
[0037]
When a jump command is input from the user while playing a song corresponding to the first song data (step Sb2), the same bridge process as in the above-described medley song jump process is performed (step Sb3). .
[0038]
In this karaoke apparatus, when performing a song jump process, the user can designate a performance start portion of the next song via the operation unit 7. As a designation method in this case, for example, a plurality of jump buttons are provided on the operation unit 7 and the music portion corresponding to the jump button pressed by the user (in this embodiment, two bars before chorus, chorus of chorus) There are a method of designating one part before one bar and a chorus part), a method of designating a performance start part by the number of times the jump button is pressed, and the like. Hereinafter, the case where it is designated to jump one bar before the chorus will be described.
[0039]
While the bridge process described above is being performed, the mark before the one bar included in the control information track of the second song data is searched. Then, when the performance corresponding to the music data of the first song is stopped at the time when the bridge processing is completed, the data executed after the timing indicated by the searched one-bar previous mark, that is, after the first bar of chorus in the next music Are sequentially read from the music data reading area 42b and output to the sound source device 8b. Then, based on the data read from the music data reading area 42b, the sound source device 8b generates a musical sound signal and outputs it to the amplifier speaker 10, and starts playing the next music from one bar before the chorus (step). Sb4).
[0040]
Here, FIG. 9 is a diagram showing the processing contents of each performance system in the inter-jump jump processing. As shown in the figure, when a jump command is input to the user, the bridge processing is performed by the a system and the performance of the first music is stopped, and then the performance of the second music by the system b is performed one measure before the chorus. Start with the part. If the third song is reserved by the user, the performance of the first song by the system a is stopped, and then the song data of the third song is read from the hard disk device 5 and written in the song data reading area 42a. If a jump command is input during the performance of the second song, the same processing as step Sb2 and subsequent steps is performed, and the performance of the third song is started from the portion designated by the user.
[0041]
On the other hand, if a jump command is not input from the user during the performance of the music corresponding to the music data of the first music, the performance of the first music is continued as it is. When the performance of the first song is completed, the second song data stored in the song data reading area 42b is read from the beginning and output to the tone generator 8b. Based on the music data of the second music outputted from the music data reading area 42b, the tone generator 8b generates a musical sound signal and outputs it to the amplifier speaker 10. Thus, the performance of the music corresponding to the music data of the second music is started from the beginning of the music.
[0042]
In this way, if a jump command is input during performance of a song other than a medley song in the karaoke apparatus according to the present embodiment, the performance of this song is stopped and the performance of the next reserved song from the portion designated by the user is performed. Can start. Therefore, after singing the chorus part of the first song, enter a jump command to start playing from the chorus part of the second song, and after singing the chorus part of the second song, enter the jump command Thus, it becomes possible to start the performance from the chorus portion of the third song, and the user can continue to sing only the chorus portion in the reserved plural songs.
[0043]
In the inter-song jump processing of the karaoke apparatus according to the present embodiment, the performance start portion of the next song was one measure before the chorus, one measure before the chorus, and chorus. If, for example, a mark such as three bars before the chorus is written in the control information track, it is possible to start the performance of the next song from the portion where the mark is written.
[0044]
