Description

  The present invention relates to a karaoke apparatus capable of playing not only singing but also a musical instrument together with karaoke performance.

  Among those who enjoy karaoke, there are those who not only sing along with karaoke performance but also want to enjoy instrumental performance along with karaoke performance. That is, karaoke is used as a minus one performance device. The minus one performance is a performance in which the part that the player performs is not played.

  Also, those who perform such as bands are renting studios to practice, but the number of studios is not large. However, in recent years, karaoke rooms have become extremely popular. This karaoke room also has a soundproofing function similar to a studio, and is suitable for playing musical instruments such as bands. Also, band practice is not possible without all of them. In some cases, you may want to practice a band in a karaoke room. Further, even when the band members are not aligned, there are cases where it is desired to perform only with the aligned members and to perform the unmatched parts with the karaoke apparatus.

  However, the conventional karaoke apparatus has a function to turn on / off the model singing and melody for singing (lead melody), but has no function to turn on / off instrument sounds other than the singing melody. .

  On the other hand, as a device similar to a karaoke device, there is a device called a sequencer that automatically reads out MIDI data stored in a memory. In this apparatus, by turning off one of a plurality of tracks, it is possible to prevent the musical sound stored in the track from being generated. However, since it is not known which timbre of which instrument is stored in which track, there is a drawback in that it is necessary to examine sequence data or to find it by actually erasing the sound.

  An object of the present invention is to provide a karaoke apparatus in which a part can be muted by designating a tone color, that is, an instrument name, and a minus one performance can be easily performed.

According to the present invention, there is provided storage means for storing music data including performance data, lyrics data , chord progression data and a flag representing vocal music or instrumental music , and performance data of the plurality of parts. a karaoke apparatus and a playing means for generating a lyrics telop based on said lyrics data with playing karaoke, further comprising a specifying means for specifying the part to be muted, said playing means, said music If the karaoke song to be played is an instrumental song with reference to the data flag, the tone of the song is displayed at the start of the performance , and the mute is controlled so as not to sound the part specified by the specifying means in the performance data and executes the control, when running the mute control, instrumental music The lyrics telop based on the chord progression data without generating generates tickers chord name, and generates a telop chord name together with the lyrics telop if vocals if Re.

  In the present invention, the performance means performs a multi-part karaoke performance. Then, the accepting unit accepts designation of the part to be muted from the user. When a part is designated by the receiving means, the part is muted and a chord name telop is displayed together with the lyrics telop or instead of the lyrics telop. By displaying the chord name, the instrument player can easily perform.

As described above, according to the present invention, when the part is muted and played, the scene is displayed according to the progress of the song. Easy to understand.
In addition, it is possible to know the progress of the song as well as the lyrics. In addition, by displaying lyrics and chord names in parallel, it is possible to know the timing of chord changes according to the lyrics, and this has the advantage that the music player can easily understand the progress of the song.

  FIG. 1 is a diagram for explaining an installation form of a karaoke apparatus according to an embodiment of the present invention. This karaoke apparatus is an apparatus installed in a so-called karaoke room. A monitor 2 and a mixer amplifier 3 are connected to the karaoke apparatus body 1. The karaoke apparatus body 1 is a so-called sound source karaoke apparatus. The tone generator karaoke device synthesizes a tone signal by inputting tone data to the tone generator device. The musical sound data is described based on the MIDI format. MIDI is an abbreviation for Musical Instrument Digital Interface, and is a global standard for data exchange between electronic music related devices. The musical sound data is stored in a musical sound track in the music data.

  In addition to the karaoke device main body 1, a microphone 5 and a speaker 4 are connected to the mixer amplifier 3. Further, the mixer amplifier 3 has an input jack, and an electric musical instrument such as an electric guitar 30 and an electronic musical instrument can be connected as shown. The user can sing along with the karaoke performance using the microphone 5 and can also play the electric guitar 10. These signals are once inputted to the mixer amplifier 3 and amplified, and then emitted from the speaker 4. The operation panel of the mixer amplifier 3 is provided with a volume for adjusting the input level of a musical sound signal input from the karaoke apparatus main body 1, microphone 5, electric guitar 30 or the like, a mixing volume, and the like (user or singer or performance). Person) can adjust the gain according to his / her own performance. The musical instrument played by the user is not limited to an electric musical instrument such as the electric guitar 30 or an electronic musical instrument, and may be a natural musical instrument such as a piano 31 or a saxophone 32, for example. In this case, the musical sounds of these natural musical instruments are emitted directly from the musical instruments.

  This karaoke apparatus can perform a so-called minus one performance. In other words, it is possible to perform a performance by muting any part of the musical sound track. In the minus one performance mode, the user plays the muted part. The remote controller 6 that transmits a music selection code or the like to the karaoke apparatus main body 1 is provided with a mute switch 6a for instructing mute. The mute switch 6a is provided for each instrument that can be muted, such as piano, guitar, saxophone, and drums. When this switch is turned on at the start of karaoke performance or during karaoke performance, the part of the instrument that is switched on is muted and a minus one performance is obtained.

  FIG. 2 is a block diagram of the karaoke apparatus main body 1. The CPU 10, which controls the operation of the entire apparatus, has a ROM 11, a RAM 12, a remote control receiver 13, a display panel 14, a panel switch 15, an ISDN controller 16, a hard disk storage device (HDD) 17, a sound source device 19, D / D via a bus. An A conversion circuit 20, a DSP 21, a character display unit 23, an LD changer 24, and a display control unit 25 are connected.

  The ROM 11 stores a sequence program, font data, and the like. The sequence program is composed of a main sequencer, a musical tone sequencer, a character sequencer, a voice sequencer, and a DSP sequencer necessary for playing the music data having the configuration shown in FIG. When the music data is played, each sequencer is processed in parallel by the CPU 10. The font data is for displaying lyrics, song titles, and the like, and fonts of a plurality of types of character types such as Mincho type and round gothic type are stored.

The remote control receiver 13 receives the infrared signal sent from the remote control 6 and restores the data. Data such as a music selection code and a mute instrument code are sent from the remote controller 6 in response to the turning on of the music selection switch or mute switch. When these codes are sent, the codes are set in a predetermined register. The display panel 14 is provided on the front face of the karaoke apparatus, and displays the currently playing song code, the number of reserved songs, and the like. The panel switch 15 is provided in the front operation unit of the karaoke apparatus, and includes a song code input switch, a key change switch, and the like.

  The HDD 17 has a music data file that can store hundreds to thousands of music data, and the stored music data is identified by a file name. The ISDN controller 16 is a controller for communicating with the host station via the ISDN line. The host station stores the song data of the new song, and downloads the song data of the new song to the karaoke apparatus 1 connected via the ISDN line. The ISDN controller 16 has a built-in DMA circuit, and writes the downloaded music data directly to the HDD 17 without going through the CPU 10.

Here, the composition of the music data will be described with reference to FIG. In FIG. 2A, one piece of music data is composed of a header, a musical sound track, a display track, an audio track, a DSP control track, and an audio data portion. The header is a part in which various data relating to the music data is written. In addition to data such as the music title, genre, release date, and performance time (length) of the music, a flag indicating whether the music is a vocal song or an instrumental song and The part table shown in FIG. The sequencer 18 determines the content of the moving image background video based on the genre data, and transmits the chapter number of the video to the LD changer 24. The background video determination method is to select a video of the sea in the case of pops with the theme of summer. The part table stores a muteable flag indicating what tone color of each of the musical sound tracks (PART1 to PART16) is, and whether the part can be muted.

  As shown in FIG. 5B, the musical tone track is composed of 16 tracks (parts) for storing sequence data for each tone color. Each track stores sequence data of timbres such as a guide melody, piano, guitar, bass, and drums. The sequence data consists of event data and duration data.

  As shown in FIG. 3C, the display track is composed of three tracks: a lyrics track, a vocal chord name track, and an instrumental chord name track. The lyrics track stores the lyrics to be displayed on the monitor 26 and the display timing thereof. This track is also described in the MIDI format. The chord name track for vocals and the chord name track for instrumental memorize the chord progression of this song. This code name is displayed in minus one mode. In the case of a vocal song (a song for singing), a chord name is displayed in addition to the display of lyrics. In the case of instrumental music (instrumental music), the chord name is displayed together with the bar axis (the time axis represents a horizontal line and the bar breaks represent a short vertical line: see FIG. 5). The chord name track also stores scene data indicating which scene the current song is. The scene data includes intro, theme, rust, solo, melody, ad lib, and the like.

  The audio track is data for generating a human voice such as a back chorus or a harmony melody voice that is difficult to synthesize by the sound source device 19, and actual ADPCM data (audio data n (n = 1, 2,...)) Is generated. In combination with the written audio data part, a back chorus or harmony melody is generated in this karaoke system. In the audio track, audio specification data specifying audio data and duration data specifying timing for outputting the audio data to the D / A conversion circuit 20 are written. The voice designation data includes a voice data number, pitch data, and volume data. The audio data number is the identification number n of each audio data recorded in the audio data portion, and the audio data of this number is output to the D / A conversion circuit 20 at this time. The D / A conversion circuit 20 sets the output level based on the volume data, converts the sampling clock at the time of D / A conversion based on the pitch data, and sets the pitch of the output analog signal.

  Control data of the DSP 21 to which the sound source device 19, the D / A conversion circuit 20, and the microphone 27 are connected is written on the DSP control track. The DSP 21 is mainly for imparting a reverberation-type effect such as reverb to a musical sound, and the effect is temporally adjusted based on the effect type data and change amount data recorded in the DSP control track. .

  In FIG. 2, when the CPU 10 processes the music data based on the sequence program, the event data of the music data is input to the sound source device 19, the D / A conversion circuit 20, and the DSP 21 at predetermined timings, respectively. The CPU 10 processes the sequence program corresponding to each track in parallel and outputs the event data of each track to a predetermined device at a predetermined timing.

  At the start of karaoke performance, the CPU 10 reads the music data header based on the main sequencer. The header stores music genre data and a part table. The CPU 10 determines which background video is to be reproduced from the genre data, and outputs the chapter number (image number) to the LD changer 24. The LD changer 24 receives the chapter number, reproduces the moving image, and inputs it to the display control unit 25. Further, the CPU 10 sends the muteable part instrument name (tone name) from the part table (FIG. 3D) to the character display unit 23 and displays the instrument name at the bottom of the screen (see FIGS. 4 and 5). ).

  The event data of the musical tone track relates to the generation / stop of musical tone such as note on / off and control of the sound source device 19, and the CPU 10 outputs this data to the sound source device 19 based on the music sequencer. The event data includes channel designation data, and the tone generator 19 controls the operation of the tone generation channel designated by the channel designation data among the plurality of tone generation channels. The tone signal synthesized by the tone generator 19 is input to the DSP 21. Predetermined audio data is input to the D / A conversion circuit 20 at a timing based on the operation of the audio sequencer. The voice data is human voice data recorded by ADPCM, and the D / A conversion circuit 20 restores this data to an analog voice signal and outputs it to the DSP 21. The DSP 21 is a circuit that inputs effects such as reverberation by inputting a musical sound signal synthesized by the sound source device 19, an audio signal restored by the D / A conversion circuit 20, and a singer's singing signal input from the microphone 27. The tone signal output from the DSP 21 is amplified and output by the amplifier / speaker 22. The CPU 10 inputs the effect control data written in the DSP control track to the DSP 21 based on the DSP sequencer. The DSP 21 controls the type and degree of the effect based on this data.

The character display unit 23 develops characters of the lyrics on the memory based on the lyrics display data input from the CPU 10 based on the character sequencer. The expanded character data is input to the display control unit 25. The display control unit superimposes the character data on the moving image background image input from the LD changer 24, adjusts the display color based on an instruction from the CPU 10, and displays it on the monitor 26. The LD changer 24 incorporates about five (120 scenes) laser discs, and reproduces a moving image instructed by the CPU 10 using a chapter number. When the karaoke performance starts, the CPU 10 determines the chapter number of the moving image background video based on the genre data included in the header of the selected music data, and notifies the LD changer 24 of the chapter number.

4 and 5 are diagrams showing display examples on the monitor 2. FIG. 4 is a display example when a vocal tune is played. Along with the start of the song, muteable instrument names (piano Pf, guitar Gt, bass bass) are displayed at the bottom of the screen. In the figure, a state in which the guitar Gt is instructed to be muted is shown. As a result, the performance is a minus one mode performance. Since it is a vocal song, the chord is displayed along with the lyrics in the minus one mode ((B) in the figure). In addition, “Solo” indicating solo is displayed based on the scene data stored in the chord track in a scene without lyrics such as an interlude ((C) in the figure).

  FIG. 5 shows a display example when playing an instrumental song. At the start of the song, the muteable instrument name (piano Pf, bass bass) is displayed along with the song name, and the tonality (key F), time signature (beat 3/4) and rhythm type (rhythm Waltz) of this song are displayed. Is done. When the performance of the song is started, a bar axis (a horizontal line indicating the progress of the music and a vertical line indicating the break of the bar) is displayed, and a chord name is displayed in accordance with the chord change timing. In addition, the scene data of the current song is displayed. In FIG. 5B, “theme” is displayed as scene data, and in FIG. 4C, “ad lib” is displayed.

  6 and 7 are flowcharts showing the operation of the karaoke apparatus body 1. FIG. 6 shows the main routine of the karaoke performance operation. First, a music selection code is input using the remote controller 6 (n1). When the music selection code is input, the music data corresponding to this music selection code is loaded from the HDD 17 to the RAM (n2). The part table is read from the header of the music data, and the muteable instrument name is displayed on the monitor 2 based on the contents of the part table (n3). After this, karaoke performance starts. The karaoke performance consists of a sound generation operation (n7) and a display operation (n8). In parallel with this operation, whether or not a mute instrument code is sent from the remote controller 6 is monitored (n4). If a mute instrument code is sent, the table is searched and its part number is set to i (n5), and the mute flag MUTE (i) of the part i corresponding to the mute instrument is inverted (n6). Since the operations of n4 to n8 are repeatedly executed while the karaoke performance is being performed (n9), it is possible to immediately respond to any timing when mute is instructed during the performance.

  FIG. 7A is a flowchart showing the sound generation operation. First, 1 is set to the part pointer i (n10). It is determined at n11 whether or not the mute flag MUTE (i) of this part is set. When MUTE (i) is reset, the sounding operation is performed as usual, so the MIDI data read from the musical tone track is sent as it is to the corresponding sounding channel of the tone generator 19 (n12). If MUTE (i) is set, this part (track) is muted (n13). That is, the data of the part to be muted is sent to the sound source device 19 as usual, but at the same time, data of output level = 0 is sent to the sound source device 19. As a result, the tone signal of this part is not output to the mixer amplifier. In this way, the data read operation and tone synthesis operation are executed as usual, and only the output level is set to 0, so that when the mute is canceled in the middle of the song, the sound is started immediately by resetting the output level. can do. The mute release is set when MUTE (i) is inverted by turning on the mute switch 6a again.

  FIG. 5B is a flowchart showing the display operation. The display track is read out in parallel with the music track, and the lyrics are displayed based on the contents of the lyrics track (n20). However, this action is automatically skipped for instrumental songs because there are no lyrics. Next, it is determined whether or not the minus one mode is set, that is, whether or not any one of the mute flags MUTE (i) (i = 1 to 16) is set (n21). If it is not minus one mode, the display contents are sufficient because only the lyrics are displayed. In the minus one mode, the display of the muted instrument name on the monitor 2 is changed (n22). That is, the display color of the muted instrument name among the muteable instrument names displayed at the bottom of the monitor 2 is changed (see FIGS. 4 and 5). Next, a chord name is displayed in accordance with the progress of the song (n23). In the case of vocal music, the displayed chord name is read from the chord name track for vocal music and displayed along with the lyrics. In the case of instrumental music, it is read from the chord name track for instrumental music and displayed with the bar axis. Since the scene data of the song is also stored in the chord name track, this is also displayed simultaneously with the progress of the song.

  Thus, any musical instrument can be muted in accordance with the operation of the remote controller 6 and a minus one performance can be performed. In this case, the chord name is displayed at the same time so that the musical instrument player can easily understand the progress of the song. it can. Also, by displaying scene data indicating which scene of the current song, the performance becomes easier. In addition, since the mixer amplifier 3 is provided with an input terminal such as a guitar jack, it is not necessary to bring an amplifier when performing an minus musical performance with an electric musical instrument.

  In addition, when installing this apparatus in a karaoke room and using it for a customer, you may set minus one performance as a separate charge from normal karaoke performance. Furthermore, in this case, a separate list can be set by lending the remote control with a list of songs that can be played in minus one and a mute switch separately from the normal song list and remote control. Becomes easier.
