DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke apparatus capable of performing not only singing but also musical instruments together with karaoke performance.

[0002]

2. Description of the Related Art Some people who enjoy karaoke not only sing along with karaoke performances, but also enjoy instrumental music along with karaoke performances. That is,
Use karaoke as a minus one playing device. The minus one performance is a performance in which the part played by the user is not performed.

[0003] In addition, people who perform in a band or the like rent a studio and practice, but the number of studios is not large.
In recent years, however, karaoke rooms have been remarkably widespread and opened. This karaoke room also has a soundproofing function similar to a studio, and is also suitable for playing instrumental music such as a band. In addition, band practice cannot be done unless everyone is present. From the above situation, you may want to practice the band in the karaoke room. Further, even when the members of the band are not arranged, there is a case where it is desired to perform only the members who are arranged and to play the parts which are not arranged by the karaoke apparatus.

[0004]

However, the conventional karaoke apparatus has a function of turning on / off a melody (lead melody) for model singing or singing. However, it turns on a musical sound other than the melody for singing. There was no function to turn on / off.

On the other hand, as a device similar to a karaoke device, there is a device called a sequencer for reading MIDI data stored in a memory and automatically performing the performance. In this device,
By turning off one of the tracks, it was possible to prevent the tone stored in that track from being produced. However, since it is not known which instrument's timbre is stored in which track, there is a drawback that the sequence data must be checked or the sound must be actually erased to find the tone.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a karaoke apparatus in which a part can be muted by designating a timbre, that is, a musical instrument name, and a minus one performance can be easily performed.

[0007]

According to the present invention, a storage means for storing music data including performance data of a karaoke music composed of a plurality of parts and scene instruction data indicating a scene in the music, and a part to be muted is designated. A designating means, a performance means for playing a karaoke song according to the performance data of the plurality of parts, and a mute for the part designated by the designating means; and A scene display means for displaying a scene in the song of the karaoke song based on the scene instruction data is provided.

According to the present invention, the performance means executes a karaoke performance of a plurality of parts. The multiple parts are generally composed of different tones. The receiving means receives an input of a tone color name from a user. This tone color name is the tone color name of the part to be muted. Since the timbre name is an instrument name, the user only has to input the name of the instrument to be played by the user. The table stores the tone color name of each part. When a timbre name is input from the receiving means, a part corresponding to the timbre name is searched, and the part is muted. At this time, a scene is displayed based on the scene instruction data. The scene is, for example, a theme or an ad lib.
This makes it easier for a person playing the muted part to know what performance to perform.

Waltz) is displayed. When the performance of a song is started, a bar axis (horizontal line indicating the progress of the song and vertical line indicating a break of the bar) is displayed, and a chord name is displayed at the same time as the chord change timing. Further, the scene data of the current song is displayed. FIG. 2B shows “theme” as scene data, and FIG. 2C shows “ad lib”.

FIGS. 6 and 7 are flowcharts showing the operation of the karaoke apparatus main body 1. FIG. 6 shows the main routine of the karaoke performance operation. First, a music selection code is input using the remote controller 6 (n1). When the music selection code is input, the music data corresponding to the music selection code is set to H
The data is loaded from the DD 17 to the RAM (n2). The part table is read from the header of the music data, and the name of the mutable instrument is displayed on the monitor 2 based on the contents of the part table (n3). After that, start karaoke performance. The karaoke performance includes a sound generation operation (n7) and a display operation (n8). In parallel with this operation, it is monitored whether a mute instrument code is sent from the remote controller 6 (n4). If you receive a mute instrument code,
Search the table and set its part number to i (n
5) Invert the mute flag MUTE (i) of part i corresponding to the mute instrument (n6). Since the operations of n4 to n8 are repeatedly executed while the karaoke performance is being performed (n9), it is possible to immediately respond to any timing during which the mute is instructed during the performance.

FIG. 7A is a flow chart showing the sound generation operation. First, 1 is set to the part pointer i (n10). Mute flag of this part MUTE
It is determined at n11 whether or not (i) is set. M
When UTE (i) is reset, the tone generation operation is performed as usual, so that M
The IDI data is transmitted as it is to the corresponding sounding channel of the tone generator 19 (n12). If MUTE (i) is set, this part (track) is muted (n13). That is, the data of the part to be muted is transmitted to the tone generator 19 as usual, but at the same time, the data of the output level = 0 is transmitted to the tone generator 19. As a result, the tone signal of this part is not output to the mixer amplifier. As described above, the data readout operation and the tone synthesis operation are performed as usual, and only the output level is set to 0. When the mute is released in the middle of the music, the output level is reset to immediately start sound generation. can do. The release of the mute is set when MUTE (i) is inverted by turning on the mute switch 6a again.

FIG. 3B is a flowchart showing the display operation. The display tracks are read out in parallel with the musical tone tracks, and the lyrics are displayed based on the contents of the lyrics tracks (n20). However, this operation is automatically skipped because there is no lyrics for instrumental songs. Next, it is determined whether or not the mode is the minus one mode, that is, whether or not any one of the mute flags MUTE (i) (i = 1 to 16) is set (n2).
1). If the mode is not the minus one mode, the display returns only because the lyrics are sufficient. If the mode is the minus one mode, the display of the name of the muted instrument on the monitor 2 is changed (n22). That is, the display color of the name of the muted instrument among the names of the mutable instruments displayed at the bottom of the monitor 2 is changed (see FIGS. 4 and 5). Next, a chord name is displayed in accordance with the progress of the music (n23). In the case of a vocal song, the displayed chord name is read from the vocal song chord name track and displayed along with the lyrics. In the case of an instrumental song, it is read from the instrumental song chord name track and is displayed together with the bar axis. Since the scene data of the music is also stored in the chord name track, it is also displayed simultaneously with the progress of the music.

Thus, any musical instrument can be muted in response to the operation of the remote controller 6 to perform minus one performance. In this case, the chord name is displayed at the same time so that the musical instrument player can easily understand the progress of the music. can do. Also, by displaying scene data indicating which scene of the current song, the performance becomes easier. In addition, since the mixer amplifier 3 is provided with an input terminal such as a guitar jack, it is not necessary to bring an amplifier when carrying an electric instrument and performing minus one.

When this apparatus is installed in a karaoke room for use by customers, minus one performance may be set at a different fee from normal karaoke performance. further,
In this case, a remote control with a list of songs capable of performing minus one and a mute switch is manufactured separately from the normal song list and the remote control, and the remote control can be rented at a different fee, thereby setting a different fee. It will be easier.
