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 a medley performance by extracting a performance section from music data of a plurality of karaoke music pieces and continuously playing the music data.

[0002]

2. Description of the Related Art Among music data played by a karaoke apparatus, there is a so-called medley song made by connecting well-known portions of a plurality of karaoke songs, and the popularity of karaoke singers has been increasing. ing.

[0003]

The medley tune is composed by connecting a plurality of tunes, but the medley tune itself is one karaoke tune, and each of the plurality of tunes is separately formed as a karaoke tune. Even if they were registered, they had to be created separately. Therefore, on the side of registering the karaoke song to the karaoke apparatus, it is necessary to produce the medley song separately from the plurality of songs, which takes time and effort, and is performed after the individual karaoke song is released (registered). There was a problem that the release was greatly delayed because it needed to be produced. Also, medley songs have the same data volume as normal karaoke songs,
There is a problem that a storage area is required for that. Further, on the user side, the song that the user wants to sing is not always the medley song, so the registered medley song may not be the one he likes.

[0004] It is an object of the present invention to provide a karaoke apparatus capable of performing a medley performance by connecting some performance sections of a song selected by a user from existing karaoke songs.

[0005]

According to a first aspect of the present invention, there is provided a song designating means for designating a plurality of karaoke songs and a content of each song data for executing the plurality of karaoke songs. Performance section determining means for determining a start position and an end position of a medley performance section in each music data, and performance execution means for continuously playing the plurality of karaoke songs by sequentially connecting the medley performance sections of each music data. , Is provided.

According to a second aspect of the present invention, the performance section determining means determines one or both of a start position and an end position of the medley performance section based on the presence or absence of main melody data on the time axis of the music data. It is characterized by a means for determining.

In the present invention, when the user selects and designates a plurality of karaoke songs, the karaoke songs are connected to perform a medley performance. The medley performance is a performance mode in which a melody part is connected continuously for a plurality of music pieces without a prelude or a subsequent performance. If all the melody parts of a plurality of music pieces are played, the performance becomes too long. Therefore, only a part of the melody part, such as the first melody part, is set as a medley performance section. The user may arbitrarily specify the performance section, or the karaoke apparatus may fixedly or automatically specify the performance section. However, since the data indicating the start position and the end position of the performance section is not written in the music data, the karaoke apparatus determines the performance section on the music data based on the content of the music data. For example, the song data includes a melody track for a singing guide, but note data (data for controlling pronunciation) exists in the singing portion such as No. 1 and No. 2,
There is no note data in the performance-only part such as the prelude, interlude, and subsequent performance. Therefore, when the number 1 is designated as the performance section, it can be determined that the number from the timing of the first note data of the melody track to the beginning of the section where the note data is lost for a certain period of time is the first. Also,
If the climax part of a song is specified as a performance section, reference is made to the backing track on which the data of the accompaniment sound is written, in addition to the melody track, and the change in the volume and motif is detected to determine the climax part. What should I do?

As described above, when a performance section is designated by musical content such as No. 1 or rust portion, the location of this section is detected on the music data, and only that section is performed. Even if there is no mark indicating a section, a specified performance section can be found on the music data and only that section can be played.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A karaoke apparatus according to an embodiment of the present invention will be described with reference to the drawings. This karaoke apparatus stores music data for about 10,000 karaoke music performances, reads out the music data according to the music numbers registered and reserved by the user, and plays the karaoke music. Also, in the medley mode, only the first of a plurality of selected karaoke songs is connected without a break and played continuously. Although no data indicating the performance section for medley performance is written in the normal music data, this karaoke apparatus can determine the performance section based on the content of the music data, and which music data medley performance can be performed. Can be.

FIG. 1 is a block diagram of a karaoke apparatus having the medley performance function. The CPU 10, which controls the operation of the entire apparatus, has a ROM 11, a RAM 1

An amplifier speaker 26 is connected to the mixer 22, and a vocal microphone 27 is connected to the effect DSP 21c. A monitor 28 is connected to the display control unit 25. The amplifier speaker 26, vocal microphone 27, and monitor 28 are separate from the karaoke apparatus main body.

The ROM 11 stores a startup program and the like. The startup program is read when the power of the apparatus is turned on. The system program, the karaoke execution program group, the loader, and the like stored in the hard disk storage device 14 are read into the RAM 12 to start the apparatus. The system program is a program that controls the basic operation of the device and data transmission / reception with peripheral devices. The karaoke execution program group executes operations as shown in the flowcharts of FIGS. The loader is a program for downloading music data for karaoke performance from the distribution center via the communication control unit 15.

In the RAM 12, the program read area and the music data read area for two songs are set.
The song data read area for two songs is set in parallel with the song data of the currently played karaoke song and the song data of the next karaoke song played in the medley mode. In the RAM 12, a reservation list for registering a music number input by the user, a start mark data storage area and an end mark data storage area for storing a start position and an end position of a performance section in the medley mode are set.

The communication control unit 15 downloads music data for karaoke performance from the center and writes it to the HDD 14. The communication control unit 15 has a built-in DMA circuit, and can directly write the downloaded music data to the HDD 14 without passing through the CPU 10. HDD1
4 is provided with a music data storage area for accumulating and storing about 10,000 pieces of downloaded music data.

The commander receiving section 16 receives the infrared signal sent from the commander 3 and restores the data. The commander 3 has various key switches such as a numeric keypad and a mode switching key. When the user operates these switches, the commander 3 transmits an infrared signal of a code corresponding to the operation. The user can input a song number to the karaoke apparatus main body by turning on the various key switches. By operating the mode switching key,
It is possible to switch between the normal mode in which the songs are played separately and the medley mode. Also, using the commander 3 to perform a medley performance section (only the first, only the second,
, No. 2 and No. 1 only). It is also optional whether this designation is common to all songs or individual for each song.

The display panel 17 includes an LED display for displaying the input music number and the like. Also,
The panel switch 18 includes a key switch of the same type as that of the commander 3 in addition to the numeric keypad. The panel switch can be operated to input a music number.

This karaoke apparatus has two systems (a system, b system).
Karaoke performance section (sound source device 19, audio data processing section 20, effect DSP 21). this is,
This is because the karaoke performance of the previous tune and the karaoke performance of the next tune are performed in different systems in order to smoothly carry over the performance when the performance switches from the previous tune to the next tune in the medley performance mode. In a normal mode in which only one song is played, only one of the systems may be used, or both systems may be operated to create a thick sound.

Hereinafter, one system will be described. The sound source device 19 forms a tone signal based on note event data input from the CPU 10 during a karaoke performance. The note event data is data written in a musical tone track, a melody track, and a rhythm track of the music data, and is data for controlling tone generation / muting of a musical tone. The audio data processing unit 20 forms an audio signal such as a back chorus based on the audio data. The audio data is obtained by converting a signal waveform (such as a back chorus) that is hardly generated electronically by the sound source device 19 from a raw audio signal to an ADPC
The audio data processing unit 20 decompresses the M data and outputs it. DSP 21 for effect is sound source device 1
Various effects are given to the tone signal input from the input unit 9 and the audio signal expanded by the audio data processing unit 20. The karaoke performance sound given the effect is output to the mixer 22.

On the other hand, the singing microphone 27 is connected to the preamplifier 3.
Connected to 0. The singing voice signal input from the microphone 27 is amplified by the preamplifier 30 and is amplified by the A / D converter 3.

c. The effect DSP 21 c adds an effect such as an echo to the singing voice signal, and outputs the signal to the mixer 22. The mixer 22 mixes the karaoke performance sound and the singing voice signal input from the DSPs 21a, 21b, 21c at an appropriate ratio, converts them into analog signals, and outputs them to the amplifier speaker 26. The amplifier speaker 26 amplifies this analog signal and emits it from the speaker. Note that DS
The type and degree of the effect given to P21a, 21b, 21c is controlled by DSP control data input from CPU10. The DSP control data is stored in the DSP control track of the music data together with the delta time data.
To enter.

The character display section 23 receives character display data for displaying the title and lyrics of the karaoke song. The character display data is data written in the character display track of the music data, and the time interval data is displayed so that the song title and lyrics are displayed in synchronization with the karaoke performance based on the tone track and the display color is changed. (Delta time data). The character display unit 23 generates character patterns such as song titles and lyrics based on the character display data. Also, the CD-ROM changer 24 stores the MPE on the CD-ROM when performing karaoke.
Play video recorded in the G format. CP
U10 decides what kind of background picture is to be reproduced based on the genre data of the karaoke tune to be played, etc., and stores the chapter number of the background picture in the CD-ROM changer 2.
Send to 4. The CD-ROM changer 24 uses this C
The video of the chapter specified by the PU 10 is selected from a plurality of (about 5) CD-ROMs and reproduced. Character pattern and CD-R generated by the character display unit 23
The background video reproduced by the OM changer 24 is displayed on the display control unit 2.

FIG. 2 is a diagram showing a music flow of an average karaoke music played by the karaoke apparatus and a schematic structure of music data. FIG. 3 is a diagram showing a data configuration of each track of the music data. The music data includes a tone display track for karaoke performance, a track such as a character display track, an audio track, a DSP control track, a control information track, an audio data section, and a header.

In FIG. 2, the average karaoke song is a prelude (intro), No. 1 (1st chorus), No. 2 (2nd chorus), No. 3 (3rd chorus), and a follow-up (ending).
, And each chorus contains the most prominent part (rust). Also, an interlude is inserted between No. 1 and No. 2 and / or between No. 2 and No. 3. The backing track (musical sound track, voice control track, etc.) and the rhythm track for generating performance musical notes and the rhythm track have note event data written throughout them, while the melody tracks for singing guides are numbered 1, 2, and 3. Note event data is written only in the singing section of the number. In the control information track, an intro start mark, a first start mark, a second start mark, a third start mark, an ending start mark, an interlude start mark, a chorus start mark, and a chorus end mark indicating the above section are written. ing. However, these data are data written at the position of a bar line that separates measures, and a mark of a weak melody (a melody starting from a weak beat such as the fourth beat) does not coincide with the start point and end point of this mark. The control information track also includes data indicating the setting / change of the tonality (key: C major, A minor, etc.) and time signature (4 time, 3 time, etc.) of the music, time signature, and the number of beats (1 beat). The data for displaying the eye, second beat, etc.) is also written.

In FIG. 3, data for performing all of the above-mentioned prelude, No. 1, No. 2, No. 3, post-play and interlude are implemented in the musical tone track.
It consists of multiple tracks that handle multiple parts such as stringed instruments. The musical tone track is composed of event data for instructing tone generation and silence of musical tones, and delta time data (Δt) representing the read timing of the event data by a time interval between the event data. The event data is note event data (note-on data, note-off data) that instructs the above-mentioned musical tones and mute.
In addition, data (parameter change, program change, etc.) for tone adjustment and change is included. CP
U10 reads the data of this track based on the sequence program. When the delta time data is read, it is counted down according to the tempo clock, and when the count value becomes 0, the next data is read. When the event data is read, the event data is output to the sound source device 19 or the corresponding functional unit. The melody track and the rhythm track have the same data structure. The data of the melody track is input to the sound source 19 to generate a guide melody sound, and the data of the rhythm track is the sound source 1.
When it is input to 9, a rhythm sound is generated.

The character display track is sequence data in which the title and lyrics of the karaoke song are implemented, and is composed of character display data (event data) and delta time data indicating a time interval between each event data. Note that the data of this character display track is not general MIDI data, but in order to unify the implementation and facilitate the work process, all audio tracks and DSP control tracks including this track are in MIDI format. It has been described. The character display data is the character data of one line of lyrics, the display coordinates of the lyrics,
Further, it is composed of wipe sequence data for controlling color change and erasure.

The audio track is a track for controlling the reproduction timing of a plurality of types of back chorus data stored in the audio data section, and is composed of audio designation data and delta time data as event data. The voice designation data specifies which voice data is to be pitch-shifted to which frequency and which volume to sound.

The DSP control track is composed of event data and delta time data for controlling the functions of the effect DSPs 21a, 21b, 21c. The event data is data for instructing what effect and to what extent to the tone signal.

At the beginning of each track (before the intro start mark), event data for resetting / initializing the tone generator 19 and the DSP 21 and the like before the start of the karaoke performance are written together. The header is composed of various data (music code, music title, release date, performance time, etc.) relating to the music data. The genre data of the music may be included in the header or may be included as data different from the music data.

Referring to the flow charts of FIGS. 4 to 7 and FIG. 8 illustrating the connection method of the performance sections of the previous and next music pieces, the connection method of the performance sections in the karaoke apparatus will be described.

FIG. 4 is a flowchart showing the reservation operation. When the user enters a song number using Commander 3,
The song number is registered in the reservation list. If the previously entered song number is registered in the reservation list, the current song number is registered below it. The song numbers registered in the reservation list are read out from the higher-ranking ones by the karaoke performance execution program, and the performance of the corresponding karaoke music is executed. The read song number is deleted,
Lower ones are moved up. 1 in the reservation list
About 0 song numbers can be registered in advance.

FIG. 5 is a flowchart showing the reservation list execution processing operation. This operation is performed at regular intervals. First, it is determined whether a music number is registered in the reservation list (s10). If there is no reserved song, the routine returns. If there is a reserved song, it is determined whether or not the current mode is the medley mode (s11). In the case of the normal performance mode instead of the medley mode, it is determined that the music is not being played at that time (s12), and the music number registered at the head of the reservation list is read out to execute the performance processing ( s13). Since the performance processing is a general processing operation, a detailed description thereof will be omitted.

On the other hand, in the case of the current medley mode, it is determined whether or not the music is currently being played in the medley mode (s1).
4). If a tune is being played, it is determined whether the preparation flag is set (s15). The setting of the preparation flag indicates that the music to be played next (the next music) in addition to the music currently being played (the previous music) has already been read out to the RAM 12 and prepared. When the performance of the previous song ends and the performance of the next song starts, the preparation flag is reset. Until then, no new music data can be read, and if the preparation flag is set, the process returns. If the preparation flag has been reset (s15), the preparation processing operation of FIG. 6 is executed.

Further, in the medley mode (s11), when no music is currently played (s14), it means that the medley performance is to be started from now on. After preparing the first song of the medley with the song data of the song number specified (s1
7) The medley performance processing operation (s18) is started.

FIG. 6 is a flowchart showing the medley preparation processing operation. First, the music data specified by the music number registered at the top of the reservation list is read into the read area of the RAM 12 (s21). Then, each track including the melody track of the music data is scanned from the beginning (s22), and the following processes are sequentially executed. If this song is the first song of Medley (s
23) Jump to s28 to play from the beginning of the song (prelude: intro). The first song includes the case where the first song is entered after entering the medley mode, and the case where the reservation of the song is interrupted in the medley mode and the performance ends, and then the song is entered again and the performance is started. If it is not the first song, the prelude of the song is cut and the performance is started from the first beginning, so that a preparation flag is first set (s24), the song data is read from the beginning, and the parameters to be read are stored (s25). ). That is, the sound source 19 and the D
A new parameter is set in SP21 and the like, and the operation is updated. However, since the performance of the second and subsequent songs of the medley starts from the middle of the song, the parameters of the previous section are read separately from the performance and set in advance. By doing so, a performance can be performed with correct parameter settings when the performance section starts. At the same time, the melody track is monitored (s26), and the timing one bar before the timing when the first note data is written in the melody track and the address of the first note data are stored as start mark data (s27). Melody start 1
The start timing before the bar is set so that one bar before the start of the melody is a bridge section for shifting from the previous tune to the next tune. Then, the reading of the melody track is continued as it is to search for a section where the note data of the melody track is interrupted for a certain time (for example, 4 bars or more) (s28), and the timing at which this section starts is stored as end mark data (s2).
9). That is, it is determined that the section in which the singing is interrupted for a certain period of time or more is an interlude, and the section immediately before that is the first melody section. After that, the parameter is set to an unused one of the two systems (a, b) of the karaoke performance section which is not used for the current performance (performance of the previous song) (s30). In the case of the first tune in which both systems are not played, either may be set. Then, in s31, it is determined again whether or not this music is the first music. In the case of the first music, the medley performance process is started using this data (s32). On the other hand, if the previous song is currently being played instead of the first song, the medley preparation processing operation is terminated.

Although the above operation has been described in the case where the first start data and the first end data are not written in the control information track of the music data, the first start data and the first end data are written in the control information track. If it is, the following operation may be performed instead of s26 to s29. That is, as described above, the mark data such as the first start data and the first end data are written at the bar line position, but the melody starts from the bar line position accurately and ends at the bar line position. Not necessarily. Therefore,
With reference to these mark data, an accurate start timing before and after the mark data is searched. First, the first start data is searched (s33). When the first start data is read, a position where the note data of the melody track starts near the mark data is searched (s34), the timing one bar before the start position of the melody and the address of the note data. Is stored as start mark data (s35). Then, the first end data is searched (s36). When the first end data is read, a position where the note data of the melody track is interrupted is searched near the mark data (s37), and this timing is stored as the end mark data (s38).
According to the above operation, the start position and the end position of one chorus can be detected more accurately from the music data containing the mark data.

FIG. 7 is a flowchart showing a medley performance processing program. This program is executed independently and in parallel for each music piece at the time of linking the previous music piece and the next music piece. FIG. 8 is a diagram for explaining a method of connecting the performance sections of the previous music piece and the next music piece. First, the performance processing of the first music will be described. As in the normal performance mode, the performance of the music is executed from the beginning, and the performance is continued until the timing stored in the end mark data storage area comes (s41). During this time,
The singer can sing as usual. And
The medley preparation processing operation (FIG. 6) in parallel with this operation
Thus, the preparation of the second tune is performed, and the setup of the other karaoke performance section is performed. When the performance of the first tune (previous tune) progresses to the end mark data, the start of the performance is notified to the medley performance program for controlling the performance of the next tune (s42).

When the preparation operation of FIG. 6 is completed, the medley performance processing program for processing the performance of the next tune waits until there is a notification from the previous tune (s50), and the medley performance for controlling the performance of the previous tune. When the processing program notifies the start of the performance, only the performance of the rhythm track is started at the tempo set for this music (the next music) (s5).
1).

At this point, the medley performance processing program for the previous song has passed the tempo clock control to the program for the next song (s43), and performs tempo control according to the tempo clock for the next song. Thereafter, the medley performance processing program of the previous song executes only the note-off event data among the event data read out thereafter (s4).
4). In other words, only the tone of the musical tone that has been produced so far is executed, and no new musical tone is produced.

On the other hand, when one bar has passed after the melody performance processing program of the next music starts the rhythm performance (s51), the melody part of the next music starts because the first melody part of this music is played. The program is instructed to end the operation (s53), and the performance of all parts of the next music is started (s54).

In response to this instruction, the medley performance processing program for the previous tune (first tune) performs note-off of all currently sounding musical tones (s46). As a result, the karaoke performance section that has been processing the performance of the previous music piece becomes empty, and processing of a new next music piece becomes possible. Therefore, the preparation flag is reset (s47), and the operation ends.

By repeatedly performing the above operation for each piece of music data selected by the user, it is possible to continuously perform a plurality of music pieces.

In the above embodiment, the performance section is fixedly numbered one, but the performance section is not limited to this, and the karaoke apparatus may automatically change the karaoke apparatus according to the music or arbitrarily. Good. The user may be allowed to specify a performance section. This specification may be either specification for the entire medley music or individual specification for each music.

[0041]

As described above, according to the present invention, when a plurality of karaoke songs are medley-played, even if data indicating the medley performance section is not present in the song data,
Since the performance section can be detected and played based on the contents of music data such as melody tracks, natural medley performance can be performed no matter what karaoke song is specified, and karaoke of medley songs can be performed. This eliminates the need for specially creating song data, and saves time and makes it possible to play the song as part of the medley immediately when the song data of a normal karaoke song is registered.
