Description

The present invention relates to an automatic performance device capable of performing a medley performance by extracting a performance section from a plurality of music data and performing the performance section continuously.

In the karaoke machine which is an automatic performance device, there is a so-called medley song created by connecting well-known parts of multiple karaoke songs in the music data to be played, and the popularity of karaoke singers has been increasing. I am collecting.

A medley song is made by joining a plurality of songs. However, even if the medley song itself is a single karaoke song and the plurality of songs are individually registered as karaoke songs, It had to be created separately. Therefore, on the side of registering the karaoke song in the karaoke apparatus, it is necessary to produce the medley song separately from the plurality of songs, which takes time and effort, and is also required after the individual karaoke song is released (registered). There was a problem that the release was greatly delayed because it had to be produced. Also, since the medley tune has the same data amount as a normal karaoke tune, there is a problem that a storage area for that is required. Furthermore, on the user side, the song that he / she wants to sing is not always the medley song, so the registered medley song may not be his / her favorite.

An object of the present invention is to provide an automatic performance device that enables a continuous medley performance by connecting partial performance sections of a music selected by a user from ordinary music.

According to the present invention, a song designating means for designating a plurality of songs, and a start position and an end position of a medley performance section in each song data based on contents of each song data for executing the plurality of songs. And a performance section for performing a continuous play of the plurality of music pieces by sequentially connecting the medley performance sections of each piece of music data. The performance execution means comprises two systems of music performance sections. Means for alternately playing the plurality of medley sections, wherein, while performing performance in one music performance section, performing setup for performance of the next medley section in the other music performance section. It is characterized by.

The present invention is characterized in that the performance executing means executes setup for the other music performance section by inputting setting parameters of music data to the other music performance section.

According to the present invention, the performance executing means starts the performance of the other music performance section before the performance of the one music performance section is completed, and the rhythm track is added to the other music performance section until the performance of the one music performance section is completed. It is characterized by having only one perform.

The present invention is characterized in that when the performance executing means starts the performance of the other music performance section, the performance tempo of the one music performance section matches the performance tempo of the other music performance section. .

The present invention is characterized in that when the performance execution means starts the performance of the other music performance section, the one music performance section executes only the note-off event of the event data read from the music data. I do.

As described above, according to the present invention, when a plurality of music pieces are medley-played, a natural medley performance can be performed without interruption of the music pieces at the joints of the music pieces, and it is necessary to specially create medley-specific music data. This eliminates the hassle and makes it possible to immediately play the song as part of the medley using normal song data.

A karaoke apparatus according to an embodiment of the present invention will be described with reference to the drawings. In the karaoke apparatus described below, when a user selects and designates a plurality of karaoke songs, the user performs a medley performance by connecting the karaoke songs. The medley performance is a performance mode in which a melody part is connected to a plurality of music pieces and a continuous performance is performed without a prelude or a postlude. If all the melody parts of a plurality of music pieces are played, the performance becomes too long. Therefore, a part of the melody part, such as only the first melody part, is defined 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, song data includes a melody track for a singing guide, but singing portions such as No. 1 and No. 2 contain note data (data for controlling pronunciation), and performers such as preludes, interludes, and subsequents. There is no note data in only the part. 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 time is the first. If the climax part of the song is specified as a performance section, the climax part is detected by detecting not only the melody track but also the backing track on which the data of the accompaniment sound is written, and detecting changes in the volume and musical ideas. You just have to figure it out.

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

FIG. 1 is a block diagram of a karaoke apparatus having the medley performance function. 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 seamlessly and played continuously. Although the data indicating the performance section for the medley performance is not written in the normal music data, this karaoke apparatus can determine the performance section based on the content of the music data, and any music data performs the medley performance. be able to.

The CPU 10 that controls the operation of the entire apparatus includes a ROM 11, a RAM 12, a hard disk storage device (HDD) 14, a communication control unit 15, a remote control receiving unit 16, a display panel 17, a panel switch 18, and sound source devices 19a and 19b via a bus. , Audio data processing units 20a, 20b, effect DSPs 21a, 21b, 21c, a mixer 22, a character display unit 23, a CD-ROM changer 24, and a display control unit 25. 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.

(4) The ROM 11 stores a startup program and the like. The startup program is read when the power of the apparatus is turned on, and 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 an operation as shown in the flowcharts of FIGS. The loader is a program for downloading music data for karaoke performance from a distribution center via the communication control unit 15.

The program read area and the music data read area for two songs are set in the RAM 12. The song data reading area for two songs is set in parallel with the song data of the karaoke song currently being played and the song data of the karaoke song to be played next 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 going through the CPU 10. The HDD 14 is provided with a music data storage area for storing and storing about 10,000 downloaded music data.

The commander receiving section 16 receives the infrared signal sent from the commander 3 and restores the data. The commander 3 includes 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. Further, by operating the mode switching key, it is possible to switch between the normal mode in which each piece of music is played separately and the medley mode. Alternatively, the commander 3 may be used to specify a performance section during medley performance (only the first section, only the second section, only the first and second chorus portions, etc.). 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. 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.

The karaoke apparatus includes two karaoke performance units (a system and b system) (a sound source device 19, an audio data processing unit 20, and an effect DSP 21). This is because the karaoke performance of the previous song and the next karaoke are performed in different systems in order to smoothly carry over the performance when the performance switches from the previous song to the next song in the medley performance mode. is there. 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.

One system will be described below. 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 music data, and is data for controlling tone generation / silence 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 into ADPCM data, and the audio data processing unit 20 expands and outputs the data. 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.

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 them to the amplifier speaker 26. The amplifier speaker 26 amplifies this analog signal and emits it from the speaker. 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 together with the delta time data. The CPU 10 reads out the karaoke performance at a predetermined timing and inputs the karaoke performance to the DSP 21.

Character display data for displaying the title and lyrics of the karaoke tune is input to the character display section 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 tone track, and the time interval data is changed so that 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. Further, the CD-ROM changer 24 reproduces an image recorded in the CD-ROM 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 CD-ROM changer 24. The CD-ROM changer 24 selects and reproduces a chapter image specified by the CPU 10 from a plurality of (about five) CD-ROMs. The character pattern generated by the character display unit 23 and the background video reproduced by the CD-ROM 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.

FIG. 2 is a diagram showing a flow of music of an average karaoke music played by the karaoke apparatus and a schematic structure of music data. FIG. 3 is a diagram showing the data structure of each track of the music data. The music data is composed of 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 has a prelude (intro), No. 1 (1st chorus), No. 2 (2nd chorus), No. 3 (3rd chorus), and a follow-up (ending). Part (rust) is included. 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 musical tones are written with note event data throughout the entire tune, 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 to be written at the position of the bar line that separates the bars, and the mark and the start point and the end point of a melody of a weak eruption (a melody starting from a weak beat such as the fourth beat) do not match. 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, the second beat, etc.) is also written.

In FIG. 3, the music track implements data for playing all of the above-mentioned prelude, No. 1, No. 2, No. 3, back and interlude. Is composed of trucks. The musical tone track is composed of event data for instructing tone generation and silence of a musical tone, and delta time data (Δt) indicating a read timing of the event data by a time interval between the event data. The event data includes note event data (note-on data, note-off data) for instructing the tone generation and mute, and data (parameter change, program change, etc.) for tone color adjustment and change. The CPU 10 reads the data of this track based on the sequence program. When the delta time 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. 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 configuration. The melody track data is input to the sound source 19 to generate a guide melody sound, and the rhythm track data is input to the sound source 19 to generate a rhythm sound.

The character display track is sequence data that implements the title and lyrics of the karaoke song, and is composed of character display data (event data) and delta time data indicating the time interval between each event data. 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 includes one line of character data of lyrics, display coordinates of the lyrics, and wipe sequence data for controlling color change and deletion.

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 is to be sounded.

The DSP control track includes event data and delta time 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.

Note that event data for resetting / initializing the sound source device 19 and the DSP 21 and the like prior to the start of the karaoke performance are collectively written at the head (before the intro start mark) of each track. The header is composed of various data (song code, song name, release date, performance time, etc.) regarding 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.

The connection method of the performance section in the karaoke apparatus will be described with reference to the flow charts of FIGS. 4 to 7 and the diagram of FIG.

FIG. 4 is a flowchart showing the reservation operation. When the user inputs a music number using the commander 3, the music 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 music number is erased, and the lower music number is moved up. About ten music numbers can be registered in the reservation list 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 music, 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 (S12). 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 (s14). 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 tune ends and the performance of the next tune starts, the preparation flag is reset. Until then, new music data cannot be read, so if the preparation flag is set, the process returns as it is. If the preparation flag has been reset (s15), the preparation processing operation of FIG. 6 is executed.

Further, in the medley mode (s11), when the tune is not currently played (s14), it means that the medley performance is to be started from now on, so that the tune read from the reservation list in the preparation operation of FIG. After preparing the first song of the medley with the song data of the number (s17), 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 processing is sequentially performed by the following processing. If this song is the first song of the medley (s23), the process jumps 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 reserved and the performance is started again. 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, new parameters are set in the sound source 19, the DSP 21, and the like according to the progress of the music, and the operation is updated. However, since the music after the second music of the medley starts playing in the middle of the music, the performance of the section before the music is started. By reading the parameters separately from the performance and setting them in advance, the performance can be performed with the 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). One bar before the start of the melody is set as the start timing so that one bar before the start of the melody is set as a bridge section for shifting from the previous music to the next music. 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 (s29). ). That is, it is determined that the section where 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 parameters are set to the empty system which is not used for the current performance (the performance of the previous tune) among the karaoke performance units of the two systems (a, b) (s30). In the case of the first tune in which both systems are not played, either may be set. 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 processing 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 ends.

Although the above operation has been described for 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. In such a case, 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 exactly from the bar line position and ends at the bar line position. Not necessarily. Therefore, an accurate start timing before and after the mark data is searched with reference to these mark data. 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). By 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 song and the next song. First, the performance process 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 is reached (s41). During this time, the singer can sing as usual. In parallel with this operation, the second tune is prepared by the medley preparation processing operation (FIG. 6), and the other karaoke performance section is set up. When the performance of the first tune (previous tune) progresses to the end mark data, the start of the performance is notified to this medley performance program for controlling the performance of the next tune (s42).

When the preparatory 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). When the performance start is notified, only the performance of the rhythm track is started at the tempo set for this music (the next music) (s51).

At this point, the medley performance processing program of the previous music has passed the tempo clock control to the program of the next music (s43), and performs the tempo control according to the tempo clock of the next music. Thereafter, the medley performance processing program of the previous song executes only the note-off event data among the event data read out thereafter (s44). 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 elapsed after the melody performance processing program of the next music starts the rhythm performance (s51), the melody part of the next music is played because the first melody part of this music is played. In addition to instructing the end (s53), the performance of all parts of the next music is started (s54).

(4) The medley performance processing program for the previous tune (first tune) performs note-off of all currently sounding musical tones in response to this instruction (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.

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

In the above-described embodiment, the performance section is fixedly numbered 1. However, the performance section is not limited to this, and the karaoke apparatus may automatically change the performance in accordance with the music or arbitrarily. Further, the user may be allowed to specify a performance section. This designation may be either a designation for the entire medley song or an individual designation for each song.
