An application using information ("MIDI" is a registered trademark) has also been filed. This is information standardized internationally and indicates coloring, pitch, volume, and the like. That is, the MIDI information is read, and a predetermined accompaniment music is reproduced by a musical sound reproducing means such as a synthesizer via the MIDI interface.

In a karaoke apparatus using such a musical tone information storage medium, for example, when a singer selects a desired song, the accompaniment sound is usually reproduced so that the song can be sung in a full chorus (generally number 1 to 3). It is a mechanism.

In addition, recent karaoke apparatuses are provided with a mechanism for displaying a background image in addition to the karaoke accompaniment, and the display image includes a lyric information stored for each tune in the musical sound information storage medium. Is converted into an image signal and projected on a display screen together with a background image.

[Problems to be Solved by the Invention] However, in the musical sound reproducing apparatus such as the above-mentioned karaoke apparatus, a user such as a singer can only select a desired musical piece, and the reproduced musical accompaniment sound and image are displayed. The lyrics are reproduced in the order stored as the musical sound information, that is, in the order of the prelude section, the chorus section (each number of the song), the interlude section for each chorus, and the backtrack section.

Therefore, it has been difficult for the singer to sing the chorus in any order of singing, because the displayed lyrics and the like do not match.

However, in karaoke, trendy songs are played many times in a short period of time, and the listeners often get bored, and the singers sometimes want to change the order of singing and wish to change. is there.

In such a situation, there has been a problem that the accompaniment and the interlude music of each chorus section are to be reproduced in the chorus order desired by the singer, and the lyrics display is to be adapted to the order.

The present invention has been made in order to solve the above problems, and an object of the present invention is to reproduce one karaoke song.
It is an object of the present invention to provide a musical sound reproducing apparatus capable of reproducing an accompaniment sound according to a changed chorus order without deteriorating the flow, and displaying corresponding lyrics in the changed chorus order.

[Means for Solving the Problems] To achieve the above object, a karaoke reproducing apparatus according to the present invention comprises a music storage unit, an input unit, a control data storage unit, a control unit, a musical sound reproduction unit, and a video conversion unit. In the karaoke reproducing apparatus, the music storage means includes: music information divided into a prelude section, a plurality of chorus sections, one or more interlude sections, and a rearrangement section; lyrics information corresponding to each chorus section; Storing control data for specifying the order, input means,
The playback order of the chorus section is specified, and the control data storage means stores control data obtained by changing only the playback order of the chorus section based on the playback order of the specified chorus section,
The control means sequentially reads out the music information and the lyrics information based on the reproduction order of the control data stored in the control data storage means, and the music reproduction means reproduces the read music information,
The video conversion means is configured to perform conversion so as to output the read lyric information to the lyric display means.

[Operation] In the karaoke reproducing apparatus having the above configuration, the music storage means
Musical sound information divided into a prelude, a plurality of choruses, one or more interludes, and a rearrangement, lyric information corresponding to each chorus, and control data for specifying a reproduction order of the divisions are stored and used. When the user specifies the playback order of the chorus section by the input means, the control data storage means stores control data in which only the playback order of the chorus section has been changed based on the playback order of the specified chorus section, Reads out music information and lyrics information sequentially based on the reproduction order of the control data stored in the control data storage means.
The read musical sound information is reproduced, and the video conversion means performs conversion so that the read lyric information is output to the lyric display means.

Therefore, for one song, the prelude, the interlude, and the rearrangement can be reproduced in a predetermined chorus order instead of the normal chorus order, and despite the change of the chorus order, as predetermined. Thus, desired changes can be made without deteriorating the reproduced music.

Thus, in a karaoke apparatus or the like, if the division information is divided into a prelude section, each chorus section, each interlude section, and a rearrangement section, the user can arbitrarily change the reproduction order of the chorus section and reproduce the musical sound. It is possible to do.
