The purpose of the present invention is to provide a performance device that can bring out the singer's singing ability.

Means for Solving the Problems In order to solve the above-mentioned problems, the performance device of the present invention includes a disc playback means for playing back compact discs, video discs, etc., and a key of the output signal of the disc playback means for playing back compact discs, video discs, etc. a key conversion means for converting the TOC data from the disk reproduction means; an amplification means for amplifying the output signal of the key conversion means; an audio signal input means for inputting the audio signal to the amplification means; It is provided with a control storage means that inputs, controls and stores sub-code data, and can control the keys of the key conversion means.

Effect of the Invention With the above-described configuration, the present invention allows the user to register a key only once for each side of the disc used, and from then on, no matter which disc is played back, the user can play the key without having to perform any key operations. The most suitable key will be automatically set.

EMBODIMENT OF THE INVENTION Below, the performance device of the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of main parts showing the configuration of a performance apparatus in an embodiment of the present invention. In FIG. 1, 1 is a disc playback means, 2 is a key conversion means, 3 is a control storage means, 4 is an amplification means, and 5 is an audio input means, which is usually composed of a microphone or the like. 6 is a signal output end, to which a loudspeaker such as a speaker is connected.

The basic operation of the musical performance apparatus of this embodiment configured as described above will be explained.

When a user plays a karaoke disc using the disc playback means 1, a performance music signal is sent to the amplification means 4 via the key conversion means 2.

On the other hand, in order to sing along with the performance music signal, the sound is inputted from the sound input means 6 composed of a microphone, etc., mixed and amplified by the amplification means 4, and connected to a public address system from the signal output end 6 to amplify the sound. You can also enjoy karaoke.

In addition, the key of the performance music signal played from the disk,
If the user's key does not match, key conversion method 2
You can use this to set the most suitable key for the user.

The control storage means 3 has a function that allows the user to register optimal key data for each side of each disc, and - if key data is registered, it automatically determines the disc to be played and selects the song to be played. The system automatically sets the optimal key for the user.

FIG. 2 shows the control storage means 3 according to the embodiment of the present invention realized by a microcomputer 10.TOC data and subcode data from the disc playback means 1 are input to an input terminal 101, and to an input terminal 102. Key data from the key conversion means 2 is input, and key data for controlling the key conversion means 2 is output from the output terminal 103. The registration switch 11 is connected to the input terminal 104 .

The operation of this embodiment will be explained below based on the flowchart K showing the main part of the processing operation of the microcomputer shown in FIG.

First, it is assumed that steps 21 and 34 are connectors, and 1cJI is deleted in the middle of the entire main program. In step 22, data from the TOC area is input when the disc is loaded. Next, in step 23, the total time in the TOC data is recorded in memory. This total time is made up of minutes, seconds, and frames. Next, in step 24, it is determined whether or not playback is in progress. If it is being played back, the process goes to step 26; if it is not being played back, it goes to step 34. This is provided to perform the following processing only during playback. In step 25, a subcode is input, and the track code of the song currently being played is recognized. Next, in step 26, it is determined whether the registration key 11 is pressed. In other words, if the registration key is pressed, the user determines that the current key data is most suitable for the song and stores it.
If the registration key is not pressed, either the user has already registered the key data or the registration process has not yet been performed. If the determination is YES in step 26, the process proceeds to step 27, and if the determination is NO, the process proceeds to step 29.

In step 27, current key data is input.

Next, in step 28, the track attributes input in step 26 and the key data input in step 27 are stored in the memory. The process then proceeds to step 34. On the other hand, if the determination in step 26 is NO, the process proceeds to step 29, but here, the
A search is made to determine whether or not the total time of the currently used disk stored in step 23 is stored. and,
If it is found that the file exists in the memory, YES is determined in step 3o, and the process proceeds to step 31. This is to identify the disc based on the total time of the disc. Further, when the determination in step 30 is NO, the process proceeds to step 34. In step 31, the tracker of the currently playing song is searched in memory, and then in step 3
In step 2, the key data on the memory corresponding to the truck shop searched in step 31 is loaded. This key data has been previously registered by the user.

Next, the process proceeds to step 33, where the key data loaded from the memory is outputted from the output terminal 103 in FIG. 2, and the keys of the key conversion means 2 are automatically set.

The process then proceeds to step 34.

In this way, once the user has registered his/her most suitable key data for each side of each disc, the microcomputer will automatically determine which song is on which disc. It will automatically be set as the user registration key.
