Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a karaoke device which can play not only a song but also a musical instrument along with a karaoke performance.

[0002]

2. Description of the Related Art Some people who enjoy karaoke want not only to sing a karaoke performance as an accompaniment but also to enjoy instrumental music along with the karaoke performance. That is,
Use karaoke as a minus one playing device. A minus one performance is a performance in which the part played by itself is not played.

Also, people who perform in bands or the like rent a studio for practice, but the number of studios is not large.
However, in recent years, the spread of karaoke rooms has been remarkably widespread. This karaoke room also has the same soundproof function as the studio, and is suitable for playing instrumental music such as bands. Also, the band cannot be practiced without all the members. Due to the above situations, it may be desirable to practice a band in a karaoke room. In addition, even if the band members are not available, there may be a case in which it is desired that only the available members perform, and the non-equal parts are performed by the karaoke device.

[0004]

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

On the other hand, as a device similar to the karaoke device, there is a device called a sequencer which reads out MIDI data stored in a memory and automatically plays. In this device,
By turning off one of the plurality of tracks, it was possible to prevent the musical sound stored in that track from being sounded. However, there is a drawback that it is necessary to check the sequence data or actually find the sound by erasing the sound, because it is not known which musical tone is stored in which track.

It is an object of the present invention to provide a karaoke device in which a part to be played can be easily muted by designating a tone color, that is, a musical instrument name.

[0007]

According to the present invention, there is provided a playing means for performing a karaoke performance of a plurality of parts, a receiving means for receiving an input of a tone color name to be muted, a table for storing a tone color name of each part, and When the receiving means receives the tone color name, the table is searched for a corresponding part, and the muted means is provided for muting the searched part.

[0008]

According to the present invention, the playing means executes the karaoke performance of a plurality of parts. The plural parts are generally composed of different tones. The reception means receives the input of the tone color name from the user. This tone color name is the tone color name of the part to be muted. Since the timbre name is the name of the musical instrument, the user may input the name of the musical instrument to be played by the user. The table stores the tone color name of each part.
When a tone color name is input from the reception means, the part corresponding to this tone color name is searched and the part is muted. As a result, a desired part can be muted by designating a tone color name, and a minus one performance can be easily performed.

Waltz) is displayed. When a song starts playing, the bar axis (horizontal line showing the progress of the song and vertical line showing the bar separation) is displayed, and along with this, the chord name is displayed at the timing of chord change. In addition, the scene data of the current song is displayed. In the figure (B), "theme" is displayed as scene data, and in the figure (C), "adlib" is displayed.

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 song selection code is entered, the song data corresponding to this song 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 mutable musical instrument name is displayed on the monitor 2 based on the contents of the part table (n3). After this, the karaoke performance starts. The karaoke performance consists of a sounding operation (n7) and a display operation (n8), and in parallel with this operation, it is monitored whether or not a mute musical instrument chord is sent from the remote controller 6 (n4). If you send me a muted instrument chord,
Search the table and set the 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 whatever timing the mute is instructed during the performance.

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

FIG. 3B is a flow chart showing the display operation. The display track is read out in parallel with the musical sound track, and the lyrics are displayed based on the content of the lyrics track (n20). However, for instrumental songs, this action is automatically skipped because there is no lyrics. Next, it is determined whether or not the minus one mode is set, that is, whether or not any one of the mute flags MUTE (i) (i = 1 to 16) is set (n2).
1). If it is not minus one mode, the display content is sufficient because only the lyrics are displayed. If it is the minus one mode, the display of the muted instrument name on the monitor 2 is changed (n22). That is, the display color of the muted instrument name among the mutable instrument names displayed at the bottom of the monitor 2 is changed (see FIGS. 4 and 5). Next, the chord name is displayed as the music progresses (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 chord name track for the instrumental song and displayed along with the bar axis. Since the scene data of the song is also stored in this chord name track, this is also displayed at the same time as the song progresses.

Thus, an arbitrary musical instrument can be muted in accordance with the operation of the remote controller 6 and a minus one performance can be performed. In this case, by displaying the chord name at the same time, the musical instrument player can easily understand the progress of the musical composition. can do. Also, by displaying scene data indicating which scene of the current song, the performance becomes easier. Further, 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 bringing an electric musical instrument and playing a minus one.

When this device is installed in a karaoke room and is used by the customer, the minus one performance may be set at a different charge from the normal karaoke performance. further,
In this case, a remote control with a list of songs that can be played by minus one and a mute switch is manufactured separately from the normal song list and remote control, and it is possible to set a different fee by lending this at a different fee. It will be easier.
