In the karaoke terminal, when a user inputs a music number, the music is reproduced based on the music data corresponding to the music number. In this case, the key of the music used in karaoke is set so that it can be easily sung by a general person, and is different from the key of the original music. On the other hand, since the key that is easy to sing is different for each user, the karaoke terminal has a change function for moving the key up and down, so that the user can change the key to a desired key. For example, change the scale up / down (transposition amount) in semitone steps (+
1, +2, 0, -1, -2, etc.).

[0004]

By the way, the user is
In many cases, he or she listens to the original song on the radio or television, and in many cases, he purchases a CD (Compact Disk) and practices the song with the original song. Therefore, the user may want to sing with the key of the original song. However, since it is not possible for general users to know how much the key should be changed to become the key of the original song, improvement in operability has been desired. In addition, since the vocal range is different between male and female, there was a similar problem when matching the key of the music to either one. The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a karaoke device that can accurately and easily change the key of a music piece to a predetermined key.

Next, the music data will be described. FIG.
(A) is a figure which shows the format of the music data for one music. In FIG. 3A, 100 is music data,
It has a header H. The header H has information such as the music number and the data length of the music data. DAB is a data section, and is composed of performance information for reproducing a music piece, lyrics information of the music piece, and the like. In the case of this embodiment, this performance information is MIDI (Musical Instrument).
Digital interface) information, but the key of that scale is set to a key that is easy for a general user to sing, and is often different from the key of the original song. In addition,
As is well known, the scale in the MIDI information is composed of data called Note code.

KOS is a key offset, which indicates a transposition amount for changing the key of the performance information to the key of the original music piece. By referring to this, the process of automatically changing the key of the music to the key of the original music is performed (details will be described later).

Next, the alternative music data 20 shown in FIG.
0 will be described. The alternative music data 200 is data used in place of the music data 100 under a predetermined condition, and is composed of a header H and a data section DAB.
The header H has information such as an alternative music number RMON for identifying the alternative music data and a data length. The data portion DAB is the data portion DAB of the song data 100 described above.
However, the key of the performance information in this case is the key of the original song. Also, each part (part for each musical instrument) in the performance information corresponds to the original song. That is, the atmosphere of the entire song is close to that of the original song.

The alternative music data 200 shown in FIG.
It is prepared as needed and is not provided for all song data. This alternative song data 200
Is prepared in the following cases. That is, when the key of the music is changed to the key of the original music by using the above-described key offset KOS, if the key of the music is far from the key of the original music, the performance music becomes unnatural and the atmosphere of the music is spoiled. Be done. Therefore, in this case, it is desirable to use the performance information dedicated to the key of the original song. Therefore, in addition to the song data 100, the alternative song data 200 for playing with the key of the original song (see FIG. (See (B)) is prepared.

Then, as shown in FIG. 3 (A), the music data for which the alternative music data 200 is prepared includes the music data 10
The substitute music number RMNO is inserted at a predetermined position of 0. By referring to this alternative music number RMNO, the corresponding alternative music data 200 can be read.

2. Operation of Embodiment Hereinafter, the overall operation of this embodiment will be described with reference to FIG.
First, when the user operates the input unit 2 to input the song number of a performance song, this song number is temporarily stored in the RAM 7. In this case, the song number may be one song or a plurality of songs. Next, the CPU 4 reads the first inputted song number from the RAM 7. Then, with reference to the song number, the corresponding song data is read from the hard disk 6 and loaded into the RAM 7. After that, the music data is sequentially interpreted, the performance information is supplied to the musical tone synthesizer 8, and the font information corresponding to the lyrics information is transferred from the ROM 5 to the image synthesizer 13.

The CPU 4 also supplies the music number included in the music data to the image reproducing device 12. Based on the music number, the CD-ROM 13 reads out the image information corresponding to the music number and supplies it to the image synthesizing device 13.

In this way, the tone signal generated by the tone synthesizer 8 is synthesized with the voice signal output from the microphone 10 by the mixer 9, and then is produced by the speaker 11 and by the image synthesizer 14. The image information and the font information of the lyrics are combined, and the image and the lyrics corresponding to the progress of the song are displayed on the display 15. Then, when the currently playing song ends, the song data of the song is erased from the RAM 7, and the next entered song number is stored in the RAM.
7, and the same operation as described above is performed based on this music number.

Next, the key change will be described in detail with reference to FIGS. FIG. 4 shows a subroutine showing an operation in which the CPU 4 monitors the state of the ORG key 3. It should be noted that this subroutine is an interrupt processing routine that is activated every predetermined period. Now, step S1 shown in FIG.
At 00, it is determined whether or not there is an ORG key event. Here, "There is an ORG key event" means
It means that there is a change in the state of the ORG key 3, which includes a change from the ON state to the OFF state and a change from the OFF state to the ON state. Then, if there is no ORG key event, it is determined to be "NO", and the operation is repeated from step S100 again at the next interrupt timing.

On the other hand, if the state of the ORG key 3 has changed, it is determined to be "YES", the process proceeds to step S110, and the O
It is determined whether the RG key is ON. If it is in the ON state, it is determined to be "YES" and step S120.
Then, the flag ORGFLG is set to "1". This flag ORGFLG is a flag indicating whether or not there is a key change, and when "ORGFLG = 1", the key change is designated. The processing of this subroutine is completed by the processing of step S120, and when the next interrupt timing comes, the operation starts again from step S100.

On the other hand, if the ORG key 3 is OFF, the determination in step S110 becomes "NO", and step S13
The routine proceeds to 0 and it is determined whether or not the ORG key is OFF. Here, if it is determined to be "YES", step S1
In step 40, ORGFLG is set to "0", and the subroutine is finished. Then, when the interrupt timing comes again, the process is performed again from the determination of step S100.

By the way, in step S130,
If "NO" is determined, it is inconsistent with the determination result of step S110, so an error is generated and the current flag ORG is set.
Maintain FLG status. As described above, the value of the flag ORGFLG is set based on the ON / OFF state of the ORG key 3.

Next, FIG. 5 is a flowchart showing the key changing process. First, as described above, when the user inputs the song number, the CPU 4 loads the song data corresponding to the song number of the song from the hard disk 6 to the RAM 7 (step S1). Then, in step S2, the register ΔKEY (register set in the RAM 7) is initialized to "0". This register ΔKE
Y is a register for storing the variation amount (transposition amount) of the scale of the Note chord in the performance information.

Thereafter, the process proceeds to step S3, and the flag O
It is determined whether RGFLG is “1”, that is, whether the key of the music is changed to the key of the original music. If this determination is “NO”, the register ΔKEY is set to “0” in step S4, and then the process proceeds to step S10. In step S10, the transposition amount stored in the register .DELTA.KEY is added to the Note code that is sequentially read as the music progresses, and the result is transferred to the tone synthesizer 8 as a new Note code. As a result, the musical sound synthesizer 8 uses the Note calculated in step S10.
A musical tone signal is generated with a scale according to the chord. However, as described above, the steps S3 and S4 are followed by the step S
When the value reaches 10, the register ΔKEY has been cleared, so the calculation result of step S10 is the original Note.
Will be the same as the code. That is, the performance is performed with the keys of the performance data of the music data 100 as they are.

Next, in step S11, it is judged whether or not the performance is finished, and if it is finished, step S1
In step 2, the flag ORGFLG is set to "0", and the process ends. On the other hand, if the performance has not ended, step S
Return to the process of 3. Now, in step S3, "YE
If it is determined to be "S", the process proceeds to step S5 and it is determined whether or not the performance of the music has started. If it is determined that the performance of the music has begun, the process proceeds to step S6, where the key offset KOS in the music data being played is found.
(See FIG. 3A) is read from the RAM 7, stored in the register ΔKEY, and then the process proceeds to step S10.

On the other hand, if the performance of the song has not started,
The determination in step S5 is "NO", and the process proceeds to step S7 to determine whether or not there is an alternative song. Specifically, C
The PU 4 accesses the RAM 7 to determine whether or not the alternative music number RMNO (see FIG. 3) is included in the music data of the music being played. If there is no alternative song, it is determined to be "NO", and the process proceeds to step S10 via step S6.

On the other hand, if the selected song data includes the alternative song number RMNO, the determination in step S7 is "YE."
S ”, and the process goes to step S8, and the alternative song number R
The alternative music data 200 corresponding to the MNO is read from the hard disk 6 and loaded into the RAM 7. Then, the process proceeds to step S9, the flag ORGFLG is returned to "0", and the process proceeds to step S10.

By the way, when the process proceeds from step S5 → S6 → S10, or in the step S5 → S7 → S6 → S10.
If it proceeds to, the value of the key offset KOS is stored in the register ΔKEY. Therefore, step S
The calculation result of 10 is the key offset K with respect to the Note code of the music data 100 sequentially read from the RAM 7.
The note code is transposed up or down by the value of the OS. In this case, since the value of the key offset KOS is set to the transposition amount for making it the key of the original music, the key of the music is transposed to the key of the original music by the process of step S10.

On the other hand, steps S7 → S8 → S9 → S10
No. of the alternative song 200 shown in FIG.
The te code is sequentially read from the RAM 7. Since the register ΔKEY in this case is reset in step S2, the calculation result of step S10 is eventually
The Note code read from the RAM 7 remains as it is, and the key of the alternative music 200 is used to perform. Since the performance data of the alternative music 200 is created according to the key of the original music, steps S7 → S8 → S9 → S10.
Even in the case of, the performance is performed by the key of the original song. As described above, when the performance of the music starts, the key of the music is changed to the key of the original music by using the key offset KOS regardless of whether or not there is an alternative music. This prevents the user from being confused as the atmosphere of the song changes in the middle, and the alternative song data 200 is stored in the RAM 7
This is to prevent the song being played from being interrupted during the loading period. As described above, according to the configuration of the present embodiment, the ORG is changed without knowing the key change value for making the original music key.
By operating the key 3, it is possible to easily change to the key of the original song.

Further, when the alternative music data 200 is used, it is possible to obtain the tone color and the mood of the musical instrument in accordance with the key of the original music, so that it is more natural than when the key of the music data 100 is changed. You can get pronunciation.

If the alternative song data 200 does not exist, the key is changed based on the key offset KOS in the song data 100, so that it is not necessary to provide the alternative song data 200 for all the songs to be distributed. It is possible to have flexibility in data distribution. For example, even if new songs occupy a large number of distributed songs and the alternative song 200 cannot be created in time, it is possible to change the original song key without any trouble. In the present embodiment as well, the key can be changed in semitone steps by operating the input unit 2, but this point is the same as in the conventional device, and therefore the description is omitted.

C: Modifications The present invention is not limited to the above-described embodiments, but various modifications described below are possible. In the above embodiment, the communication karaoke system which distributes the music data via the public telephone line or the ISDN is assumed, but the present invention may be applied to a karaoke device in which the music data is held by an optical disk or the like. .

In the above embodiment, the alternative music data 20
In the data section DAB of 0, only the performance information for reproducing the music may be stored, and the lyrics information regarding the alternative music may be shared with the music data 100.

In the above embodiment, the display 14 is asked whether or not the key of the music is changed to the key of the original music without specially providing the ORG key 3 for changing the key of the music to the key of the original music. It is also possible to display and operate the input unit 2 to input a change instruction. In this case, if the program for controlling the operation of the CPU 4 is configured to be distributed from the host computer A to the karaoke terminal B via the communication line N, the karaoke terminal B that has been used conventionally can be used to play music. It is possible to change the key to the key of the original song.

In the above embodiment, step S
In 7, it is judged whether or not there is an alternative song by referring to the alternative song number RMNO in the song data 100.
Access the hard disk 6, and substitute song data 2 there
After confirming that 00 is actually stored, "YE
It may be determined to be "S". In this case, malfunction does not occur even if the alternative song data 200 has not been distributed yet.

The key may be changed by using only the key offset KOS without using the alternative music data 200. In this case, since the alternative music data 200 is unnecessary, the data distribution can be completed in a short time, and
The capacity of the hard disk 6 can be reduced. Also, in a karaoke terminal that handles only such song data,
If steps S5 and S7 to S9 shown in FIG. 4 are omitted and “YES” is determined in step S3, the process may proceed to step S6.

On the other hand, it is also possible to change the key using only the alternative music data. In this case, the key offset KOS can be omitted from the song data 100. In a karaoke terminal that handles only such song data, steps S5 and S6 shown in FIG. 4 are omitted, and if “YES” is determined in step S3, the process proceeds to step S7, and in step S7. If it is determined to be "NO", the process may proceed to step S4.

In the above embodiment, the ORG key 3 is O
In the FF state, the key of the original song may be played, and in the ON state, a predetermined key that is easy to sing may be played. In this case, the performance information in the music data 100 and the performance information in the alternative music data 200 are reversed, and the performance information in the music data 100 is transposed by the transposition amount represented by the key offset KOS. The key offset KOS is set so that

In the above embodiment, the key offset K
The performance information in the OS and the alternative song data 200 has been described as the information for changing to the key of the original song, but the present invention is not limited to this and two types of preset keys can be selected. Good as a thing. In this case, the key before change can be used for men and the key after change can be used for women.

[0043]

As described above, according to the structure described in the claims, the key of the music piece can be automatically changed to a predetermined key, so that the key of the original music piece can be easily switched. Further, according to the configuration described in claim 1, since the key of the performance information is changed by using the transposition information, it is not necessary to separately store the performance information, and the storage area of the storage means can be reduced. According to the configuration of claim 2, the second
Since it has the second performance information corresponding to the key of, the performance according to the key can be performed. Especially when the second key is the key of the original song, the atmosphere of the original song is faithfully reproduced. can do. Further, even when the music is being played, the key of the music can be changed to the key of the original music, and the atmosphere of the music being played is not spoiled.
