[0010]
BEST MODE FOR CARRYING OUT THE INVENTION
A medley performance performed by the karaoke apparatus according to the embodiment of the present invention will be described with reference to FIG. During a normal karaoke performance, as shown in FIG. 1A, the entire data of the karaoke tune is read from the beginning to the end and the entire tune is played. The medley description file has designation data for designating a plurality of music data to be played by the medley, section designation data for designating the medley section, and bridge data for connecting the medley sections. The section designation data includes a medley start address and a medley end address.
[0011]
The medley performance is performed by connecting medley sections of a plurality of pieces of performance data, and as shown in FIG. 3B, the performance connection is improved by performing the bridge data between the medley sections. I do. The bridge data corresponds to the medley section to be played next, and plays the role of a prelude to the medley section, such as shifting the key, rhythm, and chord from the previous medley section to the medley section to be played.
[0012]
According to the present invention, since the data specifying the music data to be played by the medley and the individual bridge data are stored in a single medley description file in association with each other, each bridge data is naturally connected to the corresponding medley section. You can play medley songs with a good flow. Further, since the medley description data is identified by the same music number as the normal music data, the user can request the medley music by the same operation as the normal request operation.
[0013]
The performance data for playing a karaoke song includes not only instructing sound generation and mute, but also setting data for setting what kind of musical sound should be generated by the sound source. This is transmitted, for example, in the form of a control change message, a program change message, or a system exclusive message in the case of the MIDI format. In the performance of a general karaoke song, a sound source or the like is set at the beginning of the song and the setting is changed according to a change in the scene of the song during the performance. For this reason, the setting data is written collectively at the beginning of the performance data, and is also written at some point in the middle as necessary. When performing a normal karaoke song, the setting data may be read while performing the karaoke from the beginning, but in the case of a medley performance, it is necessary to quickly read up to the medley start address and set only the setting data to a sound source or the like. This requires several tens of seconds, but by providing two karaoke performance units and performing medley performance in one system while setting the next medley section in the other system, the performance of the karaoke will be improved. The void has been eliminated. Then, by playing the bridge data that connects the medley sections using the karaoke performance section that plays the next medley section, it is possible to generate musical tones by setting the next sound source, etc. Can play the bridge data. Further, by reading the bridge data by the sequencer in which the performance of the immediately preceding medley section has been completed, the load on the other sequencer that has read to the medley start address and is on standby can be reduced.
[0014]
This will be specifically described with reference to the block diagram of the karaoke apparatus shown in FIG. This karaoke apparatus stores about 10,000 pieces of music data for performing karaoke music on a hard disk 14 and a DVD (digital video disk), and the user uses the remote controller 3 to select a music number (four-digit singer). When the user inputs a number + a two-digit singer-specific song number), the song data of the song number is read out and a karaoke song is played.
[0015]
The karaoke apparatus can also play a medley tune that continuously plays a plurality of tunes. The performance of the medley tune is realized not by playing a piece edited as one piece of music data (medley tune) but by successively playing a partial section (medley section) of a plurality of pieces of music data. . A plurality of music data used for playing the medley music and a file indicating the medley section of each music data are stored on the hard disk 14 or DVD as a medley description file, and are identified by a music number having the same configuration as normal music data. . The singer number (5300-xx) for the medley song is attached to the song number for identifying the medley song. Bridge data, which is short performance data connecting each medley section, is also included in this medley description file.
[0016]
In order to enable such a medley performance, this karaoke apparatus is provided with two systems of karaoke performance units including a sound source and an effect DSP, and when one system is playing the first medley section, the other system is used.

[0024]
As described above, the karaoke apparatus includes two karaoke performance units (a system and b system) (sound source device 19, audio data processing unit 20, and effect DSP 21). This is when the performance switches from the previous song to the next song by performing the karaoke performance of the previous song and the karaoke performance of the next song in a different system in the medley mode, that is, shifting from the current song data to the next song data. This is in order to smoothly carry over the performance when performing. In the 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.
[0025]
Hereinafter, one system will be described. The tone generator 19 is set up with various setting data input from the CPU 10 and forms a tone signal based on note event data input from the CPU 10. The setting data includes, for example, a control change for controlling the modulation of the waveform and the degree of the filter, and a program change for changing the tone. The note event data is composed of note-on data for instructing generation of a musical tone, note-off data for instructing mute of a musical tone, and the like. These setting data and note event data are written in chronological order along with the timing data in the music progression order on the musical tone track, melody track and rhythm track of the music data.
[0026]
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 into ADPCM data, and the audio data processing unit 20 expands and outputs the data.
[0027]
The effect DSP 21 gives various effects to the tone signal input from the sound source device 19 and the audio signal expanded by the audio data processing unit 20. The karaoke performance sound to which the effect has been added is output to the mixer 22.
[0028]
On the other hand, the singing microphone 27 is connected to the preamplifier 30. The singing voice signal input from the microphone 27 is amplified by the preamplifier 30 and converted into a digital signal by the A / D converter 31, and then input to the effect DSP 21c. The effect DSP 21c 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 the analog signals to the amplifier speaker 26. The amplifier speaker 26 amplifies this analog signal and emits it from the speaker.
[0029]
Note that the type and degree of the effect given to the DSPs 21a, 21b, 21c are controlled by DSP control data input from the CPU 10. The DSP control data is stored in the DSP control track of the music data in chronological order together with the timing data in the order of the progress of the music.
[0030]
Character display data for displaying the title and lyrics of the karaoke song is input to the character display unit 23. The character display data is data written in the character display track of the music data, and the song title and lyrics are displayed in synchronization with the karaoke performance based on the musical tone track, and the timing data is changed so that the display color is changed. Implemented. The character display unit 23 generates a character pattern such as a song title or lyrics based on the character display data. Further, the DVD changer 24 reproduces a video recorded in the DVD in the MPEG format during a karaoke performance. The CPU 10 determines what kind of background video is to be reproduced based on the genre data of the karaoke song to be played, and transmits the chapter number of the background video to the DVD changer 24. The DVD changer 24 selects and reproduces a chapter image designated by the CPU 10 from a plurality of DVDs (about five). The character pattern generated by the character display unit 23 and the background video reproduced by the DVD changer 24 are input to the display control unit 25. The display control unit 25 superimposes a character pattern on the background video in a superimposed manner and displays the superimposed character pattern on the monitor 28.
[0031]
In the karaoke apparatus having the above configuration, when a user inputs a song number from the remote controller 3 or the like, the song number is registered in a reservation list in the RAM 12. The apparatus executes the karaoke performance in order from the music registered in the upper rank of the reservation list. When a normal karaoke song is requested, the song data of the song is read and played. When a medley song is requested, the medley description file of the medley song is read out, the music data specified in the medley description file is sequentially read out, and the medley section is divided into a system and a b system karaoke performance section. Play alternately with.
[0032]
With reference to FIGS. 3, 4, and 5, music data and medley description data used in the karaoke apparatus will be described. FIG. 3 is a diagram showing a configuration of music data. FIG. 4 shows the structure of the medley description file. FIG. 5 is a diagram showing the structure of a song number index file.
[0033]
In FIG. 3, the music data includes a header, a track group, and an audio data section. Bibliographic data such as song numbers and titles are written in the header. The track group includes a music track for controlling the sound source device 19, a lyrics track for controlling the display of characters such as lyrics, a voice control track for controlling voice data input to the voice data processing unit 20, and an effect for controlling the DSP 21 for effects. It is composed of control tracks.
[0034]
The musical sound track is configured by arranging event data such as note event data and setting data and timing data indicating read timing of each event data in a time series. The timing data indicates a time interval between event data. The CPU 10 sequentially reads the data of the track from the head, and outputs the event data to the tone generator 19 when the event data is read. Upon receiving this data, the tone generator 19 generates or silences a musical tone or changes a musical tone forming function. When the timing data is read out, it is counted down in accordance with the tempo clock, and when the count value becomes 0, the next data is read out.
[0035]
The lyrics track is sequence data that implements the title and lyrics of the karaoke song, and is composed of character display data, which is event data, and timing data that indicates the time interval between each event data. Although the lyrics track data is not general MIDI data, all audio control tracks and effect control tracks including this track are in MIDI format in order to unify the implementation and facilitate the work process. It has been described. The event data of the lyrics track includes one line of character data of the lyrics, display coordinates of the lyrics, and wipe sequence data for controlling color change and deletion.
[0036]
The audio control 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 timing data as event data. The voice designation data specifies which voice data is to be pitch-shifted to which frequency and which volume is to be sounded.
[0037]
The effect control track includes event data and timing data for controlling the functions of the effect DSPs 21a, 21b, and 21c. The event data is data for instructing what effect and to what extent to the tone signal.
[0038]
At the head of the track group, initialization setting data (control change data, program change data, etc.) for setting up the tone generator 19 and the effect DSP 21 in a state suitable for the performance of the music before starting the performance is written. Have been. The karaoke apparatus reads out the initialization setting data and inputs it to the sound source 19 or the DSP 21 to set up the sound source 19 or the DSP 21 in a state where the performance can be started. Then, based on the note event data read from the performance data, etc. To form musical sounds. The setting data is also written in the middle of the song as needed, and the setting is changed according to the progress of the song.
[0039]
FIG. 4 shows the structure of the medley description file. The medley description file includes a header, a plurality of medley section setting data indicating music data to be played by the medley, and bridge data connecting the medley sections. The song number, title (song name), key control permission range, and total playing time of the medley song are written in the header. The total playing time is the sum of playing times of all medley sections and bridge data.
[0040]
The medley section setting data includes a song number designating music data, a start address of the medley section in the music data, an end address of the medley section, and playing between the medley section and the next medley section. It consists of a bridge number designating bridge data, and key shift amount data indicating how much the key should be moved up and down from the original key in this medley section.
[0041]
With reference to FIG. 6, the key shift amount in each medley section and the key control permission range of the entire medley music will be described. The karaoke apparatus has a function of raising and lowering a key (tonality) of a song in accordance with a singer's voice range, and this is called a key control function. The key control can be up and down from +7 semitones (5 degrees above) to -7 semitones (5 degrees below) within the range of the sound generation function of the sound source and the processing function of digital audio (DSP etc.).
[0042]
On the other hand, if the keys of each medley section (song data) of the medley music are mixed and performed continuously as they are, unnatural modulation occurs at the joints, and the medley performance becomes poor. Therefore, key shift is performed so that each medley section has a natural tonality, and this key shift amount is written in each medley section setting data. As shown in FIG. 6, the key shift is a key in which the tonality of each medley section can be connected by the same key (or the same key), a fifth key up, a fifth key down, and a natural modulation. To do so.
[0043]
By the way, during the medley performance, the key is shifted as described above irrespective of the user operation. However, the key control function of the karaoke apparatus has a key range of +7 semitones to -7 semitones from the first key described in the music data. The key shift as described above shifts the range in which the user can move the key up and down. Each medley section is key-shifted according to the relationship between the original key of the song and the key to be matched as the medley, so that the range that can be controlled by the user can be shifted. Key control is allowed. That is, if the key control is permitted outside this range, the key in any medley section will be out of the range of +7 semitones to -7 semitones from the original. In the header, a range in which key control can be permitted for the user is written as a key control permitted range. When playing a medley tune, the karaoke apparatus reads the data in the key control permission range, and permits the user to move the key up and down within this range.
[0044]
At the time of the medley performance, two system (a system, b system) sequence programs (karaoke performance programs) operate in parallel to drive two systems (a system, b system) of karaoke performance units. During the performance of the medley section, the sequence program of the a system drives the karaoke performance section of the a system and the sequence program of the b system drives the karaoke performance section of the b system. The sequence program of the “a” system that has completed the performance drives the karaoke performance unit of the “b” system set up for the performance of the next medley section to play the bridge section, and the “b” system that has completed the performance of the medley section. The sequence program drives the a-system karaoke performance section set up for the performance of the next medley section to play the bridge section.
[0045]
The operation of the karaoke apparatus will be described with reference to the flowcharts of FIGS. 7 to 11 and the drawings of FIGS.
FIG. 7A is a flowchart showing a reservation operation by the remote controller 3 or the like. When a song number of a karaoke song is input from the remote controller 3 or the panel switch 18 (s1), the song number is registered in a reservation list (s2). This registration is performed by the FIFO, and the one registered first is played first.
[0046]
FIG. 7B is a flowchart showing the operation of confirming the reserved music. First, it is determined whether or not a karaoke song is being played (s3). If a karaoke song is being played, the process returns. If a karaoke song is not being played, the reservation list is searched (s4), and it is determined whether there is a reserved song (s5). If there is no reserved music, the process proceeds to a corresponding process such as playing BGM.
[0047]
If there is a reserved song, the song number stored at the top (head) of the reserved list is read out (s6), and the process proceeds to the performance of this song. First, it is determined whether or not this song is a medley song (s7). If the song is a medley song, the medley description file is searched and read out based on the index table (s8), and the process proceeds to the medley performance process. On the other hand, in the case of a normal karaoke song, the song data specified by the song number is read out based on the index table (s9), and the performance operation of the song data is executed. Since the normal karaoke performance operation is well known, the description is omitted.
[0048]
8 to 10 are flowcharts showing the medley performance processing.
When the medley description file is read in the processing of FIG. 7B, the process proceeds to the processing of FIG. First, the title written in the header of the medley description file is displayed on the monitor 28 (s11), the key control permission range written in the header is set in the key control permission range register, and this range is displayed on the monitor 28. To inform the singer (s12). Next, the first music performance processing is executed (s13), and in parallel with this, the second music performance preparation processing is executed (s14). The performance preparation processing includes an operation of quickly reading music data to a medley start address and setting a sound source and the like. The performance preparation processing for the second music ends earlier than the performance processing for the first music. However, when the preparation is completed, the process stands by until the performance processing for the first music ends.
[0049]
When the performance processing of the first music is completed (s15), the performance processing of the standby music (the second music) is executed (s16), and the performance sequential processing of the next music is executed (s18). This performance processing (s16) and the performance preparation processing of the next music piece (s18) are performed until the music data specified as the medley section ends, and in the case of the last medley section (s17), the performance of the music piece ends. Then, the operation is terminated (s20).
[0050]
FIG. 9 is a flowchart showing the performance processing operation of the first music. This operation is performed by driving the karaoke performance section of the a system by the sequencer of the a system (see FIG. 12A). First, the first song number is read from the first medley section setting data of the medley description file (s21), and the song data specified by this song number is read (s22). Then, the sound source is initialized by reading out the header and track data of the music data and outputting the data to a sound source or the like (s23). During the setup operation of the sound source 18a and the like, the medley end address, the key shift amount data and the bridge data connecting the first and second songs in the medley section setting data are read (s24, s25). When the initial setting of the sound source is completed, the performance processing of the first music is executed (s26). At this time, note data to be output to the sound source 18a is key-shifted and output based on the key shift amount. This performance processing is continued until the address of the music data being read reaches the medley end address. When the address of the music data reaches the medley end address, the performance of the music data is ended (by fading out) (s27), and the performance of the bridge data read earlier is performed. The process is executed (s28). This processing is performed for the karaoke performance section of the opposite system (b system) (see FIGS. 12B and 13). At this time, the set-up operation for the second music performance processing has already been set up for the performance of the medley section of the second music by the set-up operation of the performance processing of the second music (see FIG. 7A). To play the bridge data that connects the first and second songs. When the bridge section ends (s29), a trigger is output to the second song sequencer (FIG. 10) (s30), and this operation ends.
[0051]
FIG. 10 is a flowchart showing the performance preparation processing operation and the performance processing operation for the second and subsequent music pieces. In this processing operation, the even-numbered tunes of the second tune, the fourth tune,... Are performed by the b-system sequencer for the karaoke performance section of the b-system, and the odd-numbered tunes of the third tune, the fifth tune,. (See FIGS. 12A and 12C). First, a song number is read from the medley section setting data next to the currently played song (s31), and song data specified by the song number is read (s32). Then, the medley start address is read from the medley section setting data (s33), and the music data is quickly read up to the medley start address (s34). At this time, of the read data, the data other than the note data is output to a sound source or the like to perform the setup processing. Then, the medley end address, the key shift amount, and the bridge data between the next medley section are read out (s35, s36), and the performance of the medley section and the bridge data currently being played is completed, and the sequencer of the opposite system is used. It waits until there is a trigger (s37). The operation so far is the performance preparation processing of FIG.
[0052]
When a trigger is input from the sequencer on the opposite side (s37), the above-mentioned preparation processing is completed and the performance processing of the medley section in the standby state is executed (s38). At this time, note data to be output to the sound source 18 is key-shifted and output based on the key shift amount. This performance processing is continued until the address of the music data being read becomes the medley end address, and when the address becomes the medley end address, the performance of the music data is ended (by fading out) (s39), and the performance of the bridge data previously read is performed. The processing is executed (s40). This processing is performed for the karaoke performance section of the opposite system. When the bridge section ends (s41), a trigger is output to the sequencer of the opposite system that is on standby for the next medley section performance (s42), and this operation ends.
[0053]
FIG. 11 is a flowchart showing the performance operation in the last medley section. First, a song number is read from the medley section setting data next (last) of the currently played song (s51), and song data specified by the song number is read (s52). Then, the medley start address is read from the medley section setting data (s53), and the music data is quickly read up to the medley start address (s54). At this time, of the read data, the data other than the note data is output to a sound source or the like to perform the setup processing. Then, the medley end address, the key shift amount, and the bridge data (ending data) for ending are read out (s55, s56), and the performance of the currently played medley section and the bridge data is completed, and the sequencer of the opposite system is used. It waits until there is a trigger (s57).
[0054]
When a trigger is input from the sequencer of the opposite system (s57), a performance process for the last medley section for which setup has been completed is executed (s58). At this time, note data to be output to the sound source 18 is key-shifted and output based on the key shift amount. This performance processing is continued until the address of the music data being read becomes the medley end address. When the address becomes the medley end address, the performance of the music data is terminated (s59), and the performance processing of the ending data that has been read earlier is executed. (S60). Since this medley section is the last and the karaoke performance section of the opposite system has not been set up for the next medley section, this ending data is performed by the karaoke performance section of the same system. When the ending data ends (s61), the performance of the medley tune ends.
[0055]
Here, the key control operation by the singer will be described with reference to the flowchart of FIG. Key control, that is, up and down of the performance key (tonality) can be performed by operating the key control switches △ and 設 け provided on the remote controller 3 or the panel switch 18. When the △ switch is turned on once, the performance key rises by one semitone. Then, when the オ ン switch is turned on once, the performance key is lowered by one semitone. When the key-con switch is turned on (s70), it is determined whether the upper and lower sides of the key by this operation are within the permission range stored in the key-con permission range register (s71). To end the operation. If it is within the allowable range, the key shift bias register is updated (s72). This key shift bias is added to the key shift amount when the sequencer outputs note data to the sound source.

Although the bridge data is included in the medley description file, it may be stored as separate data corresponding to the medley section of each karaoke song individually. In this case, even when downloading, the music data body and the bridge data can be downloaded separately, and only the bridge data can be replaced.
[0057]
When the last bridge section ends, the ending bridge data (ending data) is played to end the song. However, the last song data is played to the end and the medley song ends. Is also good.
[0058]
Further, the bridge pattern may be generated in real time during the medley performance without storing the bridge data in the medley description file.

【The invention's effect】
As described above, according to the present invention, when a part of a plurality of karaoke songs is medley-played, the bridge data individually corresponding to each medley section is stored. A melody bridge that can be played can be played, and since each song is individual, the bridge performance does not become monotonous.
[0060]
Also, since the setting data of the sound source etc. is written in the bridge part, even if the performance data is read out from the medley section in the middle of the song, the sound source etc. is already set optimally, so it is the same as a normal karaoke performance The tone of the state can be generated.
