Technology has already been proposed. The user who is a musical instrument player can perform the musical instrument performance part by performing the musical instrument performance part that has been removed (or reduced) according to the karaoke music played in the minus one state, You can enjoy an ensemble of all karaoke songs. And the technique of displaying the chord progression of the music together with the screen for displaying the lyrics of the music to the user at the time of reproduction in such a minus one state is already known (see, for example, Patent Document 1).

JP-A-8-30284

  For example, as a musical score for guitars such as electric guitars, acoustic guitars, classical guitars, and guitar instruments having bass guitars, ukuleles, mandolin, banjos, etc., TAB scores representing fingering positions on each string are widely used. ing. Therefore, when considering the use of a musical instrument player who plays a guitar instrument, not only the chord progression is displayed on the screen as in the prior art, but also the TAB score data for the guitar instrument of the music is displayed. The performer can easily perform, and convenience is enhanced.

  By the way, in general, in a performance device that plays karaoke, it is possible to instruct key control of karaoke music data. For example, for the convenience of a user who sings and a user who plays a musical instrument, a key that is easy to sing and a key that is easy to play The key can be changed to the plus side (or minus side) to become the key. As described above, when such key control is performed when displaying the TAB score data, it is necessary to shift the TAB score data to the plus side (or minus side) in accordance with the instruction of the key control. There is.

  However, a guitar instrument usually includes a plurality of strings, and a range in which each string can be played (a range in which sound can be generated) is determined. Accordingly, when new TAB score data that is simply shifted to the TAB score plus side (or minus side) in accordance with the key control instruction as described above is generated, the shift does not deviate from the playable range. Actually, there may be a case where the performance cannot be performed according to the TAB score data.

  Moreover, the above-described key control instruction can be performed even after the reproduction of the karaoke song data is started. When the TAB music data is displayed as described above after the start of reproduction, the musical instrument player is playing the guitar musical instrument by looking at the displayed data. During the performance, if new TAB score data is generated as described above by the key control instruction again, the contents of the TAB score data may suddenly change from the previous contents. . In such a case, the musical instrument player who is playing is confused and may not be able to perform.

  An object of the present invention is to reliably display a TAB score that can be actually played by a user who plays a guitar instrument, regardless of what key control instruction is given to karaoke music data at any timing. An object of the present invention is to provide a musical sound performance device.

  In order to achieve the above object, the first invention reproduces karaoke song data composed of a plurality of instrument performance parts including a guitar instrument performance part and associated with the TAB score data of the guitar instrument performance part. Possible karaoke music reproducing means, a keycon input means capable of inputting a key for shifting the pitch of the karaoke music data reproduced by the user by the karaoke music reproducing means to the plus side or the minus side, and the keycon A TAB score shift means for generating new TAB score data by shifting the TAB score data to the plus side or the minus side according to the key control instruction input by the input means, and the TAB score shift means. The new TAB score data is provided for the guitar instrument played by the user. TAB score determination means for determining whether or not fingering data that falls outside the playable range of each string is included, and fingering data that falls outside the playable range in the new TAB score data by the TAB score determination means TAB score replacement means for generating another TAB score data in which the fingering data is replaced with fingering data of another string giving the same pitch, and the karaoke piece reproducing means Display means for displaying the new TAB score data generated by the TAB score shift means or the other TAB score data replaced by the TAB score replacement means in accordance with the reproduction of the karaoke song data of A performance signal input means for inputting a performance signal from the user's guitar instrument, and whether the performance signal is input to the performance signal input means. While it is determined that the performance signal is being input to the performance signal input means by the performance determination means after the karaoke music data has been reproduced by the performance determination means and the karaoke music reproduction means, Control means for maintaining the value of the key and the value of the TAB score data is provided.

  In the first invention of this application, karaoke song data including a guitar instrument playing part is played by the karaoke song playing means. At that time, the TAB music data of the guitar instrument performance part is associated with the karaoke music data in advance, and the TAB music is displayed by the display means when the karaoke music data is reproduced.

  Here, in the musical tone performance apparatus according to the first invention of the present application, it is possible to instruct key control of karaoke music data. For example, for the convenience of a user who sings or a user who plays a musical instrument, The key can be changed to the plus side (or minus side) so that the key becomes easy. When a key control instruction to the plus side (or minus side) is input by the keycon input means, the TAB score data associated with the karaoke song data as described above is automatically added to the plus side ( (Or minus side) to become new TAB score data.

  By the way, for example, a guitar instrument composed of a general guitar, bass guitar, ukulele, mandolin, banjo, and the like has a plurality of strings, and a range in which each string can be played (a range in which sound can be generated) is determined. Therefore, when the TAB score shift means simply generates new TAB score data shifted to the plus side (or minus side) as described above, the shift does not deviate from the playable range. , There is a case where it is not possible to perform according to the TAB score data.

  Accordingly, in the first invention of the present application, a TAB score determination means is provided, and it is determined whether or not the new TAB score data includes fingering data that is outside the playable range of each string. If there is fingering data outside such a playable range, the TAB score replacement means replaces the fingering data with another fingering data that gives the same pitch, and replaces another TAB score data. Generate. Then, the display means displays the replaced other TAB score data. Thus, regardless of what key control instruction is given to the karaoke piece data, the TAB score that can be actually played by the user who plays the guitar instrument can be reliably displayed on the display means.

  However, in the first invention of the present application, the key control instruction by the key-con input means can be performed not only before the reproduction of the karaoke song data but also after the reproduction is started. After the reproduction is started, the display means displays the new TAB score data generated by the TAB score shift means as described above, or another TAB score data replaced by the TAB score replacement means, The user is playing a guitar instrument by looking at the displayed data. Therefore, if the TAB score is suddenly shifted again or replaced as described above by the key control instruction again during such performance, the user who is performing is confused and performs the performance. There is a risk that it will not be possible.

  Accordingly, in the first invention of the present application, performance determination means is provided, and when a key control instruction is input by the key control input means, it is determined whether or not a performance signal from the guitar instrument is input by the performance signal input means. When the key control instruction is input during the reproduction of the karaoke song data, and the performance determination means determines that the performance signal is input, the control means substantially outputs the key control instruction. The key value and the TAB score data value set before the start of reproduction are maintained to be invalidated. Specifically, in the above case, the key control instruction itself is not accepted, or the key control instruction is accepted but not reflected in the reproduction content. As a result, the generation of new TAB score data by the TAB score shift means, the determination by the TAB score determination means, and the generation of another TAB score data by the TAB score replacement means are not executed, and suddenly TAB is performed during the performance. The staff will not change. Therefore, once the reproduction of the karaoke music data is started, the user can play the guitar instrument with peace of mind while watching the TAB score.

  As described above, according to the first invention of the present application, the user who plays the guitar instrument can actually perform the performance regardless of what key control instruction is given to the karaoke piece data at any timing. Possible TAB music can be displayed reliably. As a result, user convenience is improved.

  According to a second aspect of the present invention, in the first aspect of the invention, when the karaoke piece data is reproduced by the karaoke piece reproduction unit and the key control instruction is inputted by the key controller input unit, the control means determines the performance determination. If it is determined by the means that the performance signal is not input to the performance signal input means, generation of new TAB score data corresponding to the key control instruction and generation of the new TAB score data are possible. The TAB staff shift means to execute determination of whether fingering data out of range is included and generation of the other TAB music data replaced with the fingering data of the other string The TAB score judging means and the TAB score replacing means are respectively controlled.

  As described above, while the user is playing the guitar instrument, if the TAB score is suddenly shifted or replaced, the user cannot play. However, even after the karaoke song data is played, there are cases where the user is before starting the performance of the guitar instrument, or the guitar instrument performance part is closed (non-performance period) between the songs. . In such a case, there is a high possibility that the user can sufficiently follow even if the above-described TAB score shift or replacement is performed again. Therefore, in the second invention of this application, when the key control instruction is input during the reproduction of the karaoke music data, and the performance determination means determines that the performance signal from the guitar instrument is not input, the control means The above-described processing corresponding to the newly input key control instruction is executed without substantially invalidating the key control instruction. That is, generation of new TAB score data by the TAB score shift means, determination by the TAB score determination means, generation of another TAB score data by the TAB score replacement means, and the like are executed. Thus, in response to a key control instruction after playback of karaoke song data, for example, the user who performs the singing can change the key to be easy to sing, and the playing user can surely play the guitar instrument while watching the TAB score. it can.

  According to the present invention, it is possible to reliably display a TAB score that can be actually played by a user who plays a guitar instrument, regardless of what key control instruction is given to the karaoke piece data. can do.

That is, in order to pronounce the voice “C4”, it is necessary to press the fifth fret of the fifth string of the electric guitar, and in order to pronounce the voice “D4”, it is necessary to press the fifth fret of the fifth string of the electric guitar. In order to pronounce the voice “E4”, it is necessary to press the 2nd fret of the 4th string of the electric guitar, and in order to pronounce the sound “F4”, it is necessary to press the 3rd fret of the 4th string of the electric guitar. In order to pronounce “G4”, it is necessary to press the 4th string 5th fret of the electric guitar, and in order to pronounce the sound “A4”, it is necessary to press the 4th string 7th fret of the electric guitar, and the sound “B4” Is required to press the 3rd string 4th fret of the electric guitar, and the 3rd string 5th fret of the electric guitar needs to be pressed to generate the sound "C5".

<Display of TAB score data>
In the present embodiment, the TAB score data obtained by converting the TAB score into data is incorporated in the song data 100 of each song as described above. Thereby, when the song data 100 is reproduced by the karaoke apparatus 10 and the song is played, the TAB score data of the song is displayed on the monitors 13 and 14. A display example when the TAB score data is displayed on the monitors 13 and 14 is shown in FIG. 10A (the TAB score display in the right half in the figure is omitted for the sake of complexity). FIG. 11A shows a staff score and a TAB score of this example song. As shown in FIG. 10 (a), in this example, a lyrics telop of the song's lyrics "If you don't even say that word ..." is displayed, and the chord progression and the melody line are displayed below the electric guitar. TAB score data representing fingering positions to be pressed by the user (guitar player) in order to play 4 is displayed. In addition, as shown in FIGS. 10A and 11A, the chord progression is Em → Bm7 → .. in the portion corresponding to the lyrics of “That word”, and the melody of “That word” is displayed. In order to play, the 1st 3rd fret, 2nd fret, and 0th fret of the electric guitar 4 (the fingering designation with the open string that does not need to hold down the fret is referred to in this way for convenience, hereinafter the same), 2 It can be seen that the 0th and 3rd frets of the string should be used. The “keyboard” display in FIG. 10A will be described later.

<Problems caused by key control>
By the way, as already described, in the karaoke device 10, key control of karaoke music data can be instructed by the flat key 29 and the sharp key 31 of the control device 20 and the flat key 66 and the sharp key 67 of the remote controller 60. For example, when a user sings or plays a musical instrument, the key setting when the song is played is lowered to a minus side or raised to a plus side so that the key is easy to sing and play. There are many. In the present embodiment, in response to this, when the key control instruction to the minus side (or the plus side) is input, the TAB score data 160 associated with the karaoke piece data 100 as shown in FIG. , The data is automatically shifted to the minus side (or the plus side) to become new TAB score data.

  Here, the guitar instruments such as the electric guitar and the bass guitar have a plurality of strings, and a range in which each string can be played (a range in which sound can be generated) is determined. Therefore, when new TAB score data that has been simply shifted to the plus side (or minus side) as described above is generated, the shift does not deviate from the playable range. You may not be able to play on the street.

  For example, FIG. 11 (b) shows a case where the music shown in FIG. 11 (a) is lowered by one sound from the original music key shown in FIG. 11 (a). When such a key-down key control (corresponding to a key control “−2” in which the flat keys 29 and 66 are pressed twice from the standard key) is performed, as shown in FIG. All the above notes become a melody line with one note down. When the corresponding TAB score data is generated by simply lowering the TAB score data shown in the lower part of FIG. 11A by one note, as shown in the lower part of FIG. ) Is obtained by subtracting the fret number of the fingering data of the TAB score data shown in the lower row by 2 (without buying the strings). In this case, in FIG. 11A, the first sound of the first measure is “B4” and the fingering position is the 0th fret (open string) of the second string, whereas in FIG. A4 "sound, fingering position becomes -2 frets of 2 strings, and for example, in FIG. 11 (a), the 2nd sound of the 2nd measure is" E5 "sound, and the fingering position is 1 string 0 frets 11 (b), the sound is “D5”, and the fingering position is the −2 fret of the 1st string, both of which cannot be an actual guitar. This is the fingering position for "Fret". That is, there is a problem that the fingering data deviates from the playable range.

  FIG. 12A and FIG. 12B are diagrams for explaining the above-described deviation state of fingering data. FIG. 12 (a) shows the range of fingering positions in the TAB score data in the 1st bar and 2nd bar corresponding to the lyrics of the song “even that word”, and FIG. The range of the fingering position in the TAB score data generated by simply shifting as described above is shown. As shown in FIG. 12A, the fingering position in the original music key shown in FIG. 12A (indicated by the keycon “0” in the figure) is 0 in the first string. Frets (corresponding to “E5” sound), 2 frets (corresponding to “F # 5” sound), 3 frets (corresponding to “G5” sound), 2 strings 0 frets (“B4” sound) 3 frets (corresponding to “D5” sound).

  On the other hand, the fingering position of the TAB score data generated by the simple shift as described above corresponding to the key control for lowering the sound by 1 (indicated by the key-con “-2” in the figure) is as shown in FIG. From the state of a), it is simply shifted to the bass side (left side in the figure) by two frets. That is, 1st string is -2 fret (corresponding to "D5" sound), 0th fret (corresponding to "E5" sound), 2th fret (corresponding to "F5" sound), and 2nd string is -2 fret (Corresponding to the sound of “A4”) 1 fret (corresponding to the sound of “C5”) 1 finger -2 fret, 2 string -2 fret Become.

  Therefore, in the present embodiment, as described above, when fingering data at a fingering position that is an incapable range is included in the TAB score data generated by the simple shift, the fingering data is the same. Replace with another fingering data that gives the pitch. In the case of the above example of FIG. 11B, as shown in FIG. 11C, the fingering data of the 2nd string -2 fret (corresponding to the sound of “A4”) is the same as “A4”. Replace the fingering data of the 2nd fret of the other string (3 strings in this example) corresponding to the sound and the fingering data of the 2nd fret of the 1st string (corresponding to the sound of “D5”) with the same “D5” "3" fret fingering data of another string (2 strings in this example) corresponding to the sound "." When this replacement is viewed within the range of fingering positions, as shown in FIG. 12C, the fingering position of the 1st -2nd fret, which was in the unplayable range, moves to the 2nd 3rd fret. The fingering position of the -2 fret of the string moves to the 2nd fret of the 3rd string, so that all the fingering positions are outside the unplayable range (in other words, within the playable range). can do.

  In the present embodiment, another TAB score data in which all fingering data becomes playable data is generated by the above replacement, and the other TAB score data is finally displayed on the monitors 13 and 14. FIG. 10B is based on the above example, and finally the monitor 13 is displayed when the key of the song is lowered by one tone from the state shown in FIG. 10A (see “Keycon-2” display). , 14 shows an example of TAB score data. As in FIG. 10 (a), the lyrics telop of the song's lyrics "If you don't even say that word ..." is displayed, and below it, the chord progression Dm → Am7 → ... Is displayed. In addition, the final TAB score data representing the fingering position for playing the melody line is displayed. As shown in the figure, in order to play the melody of “That Kotoba” with the key down by one note, the first and third frets of the electric guitar 4, the first and third frets of the two strings, and 3 It turns out that it is only necessary to use two frets of strings.

<Processing when there are multiple fingering data replacement candidates>
By the way, when replacing fingering data by the method as described above, there may be a plurality of replacement candidates. A countermeasure in that case will be described with reference to FIGS.

  FIG. 13 shows the relationship between each fingering position and the pitch from 0 to 14th fret of the 1st to 6th strings of the electric guitar. For example, according to the above-described example, the second note “E5” in the second measure in FIG. 11A is the same as that described above with reference to FIG. Consider a case where the finger position of the 1st string -2 fret ("D5" sound) needs to be replaced. In this case, in the range up to 14 frets shown in FIG. 13, the pitch of D5 is a plurality of fingerings of 3 strings (3 strings 7 frets, 4 strings 12 frets) (in this example, 3 positions) Exists in position. That is, as described above, another TAB score data (fingering data within the fingering range) that can be played with the new TAB score data (fingering data outside the fingering range) that cannot be played due to the change of the original music key as described above. When replacing with (data), a plurality of (three in this example) fingering data of different strings that can give the same pitch exist as replacement candidates.

  However, when a plurality of strings (three in this example) are picked up, the tone (tone quality) of the fingering positions of the other strings giving the same pitch as the fingering position of one string is the above one. It is known that the strings closer to the fingering position of the strings are more aurally similar than the far strings. This will be described with reference to FIG. The thick line shown in FIG. 14A is a frequency spectrum diagram of the sound when the sound of “E5” is played with one open string, and the thick line shown in FIG. 14B is the same as “E5”. Is a frequency spectrum diagram of the sound when the sound of “4” is played at the fingering position of the 14th fret of the 4th string, and the thick line in FIG. 14C is the fingering of the 5th fret of the 2nd string of the same “E5”. It is a frequency spectrum figure of the sound when playing at a position. As shown in the figure, the frequency spectrum (Fig. 14 (a)) when the open string of the first string is played, the frequency spectrum (Fig. 14 (a)) played by pressing the two frets of the two strings that are close to the fingering position of the string. c)) has a similar spectrum envelope shape than the frequency spectrum (Fig. 14 (b)) played by pressing the 14th fret of the 4th string, where the fingering position of the string is far away. It turns out that it is a tone.

  For this reason, in the present embodiment, when the fingering data in the inoperable range is replaced with the fingering data in the playable range as described above, the replacement is performed from among a plurality of fingering data as replacement candidates. The replacement is performed using the fingering data that requires the minimum moving distance to another string, and another TAB score data is generated.

<Control procedure>
FIG. 15 shows the processing contents executed by the CPU 45 when the karaoke apparatus 10 reproduces the music, including the processing procedure for realizing generation and replacement of the TAB score data. In FIG. 15, this flow is started when the user of the karaoke device 10 presses the power button 39 of the control device 20 to turn on the power supply of the control device 20. In conjunction with the rising of the power supply of the control device 20, the power supply of the amplifier 16, the musical instrument connection board 8 and the monitors 13, 14 is started up. Note that, as described above, in this example, the user of the karaoke apparatus 10 will be described by taking the case where the electric guitar 4 is connected to the musical instrument connection board 8 for performance. That is, when the user connects the phone plug 4a of the electric guitar 4 to the phone jack 85 of the musical instrument connection board 8, the voltage appearing at the detection port P03 of the expansion I / O port 88 changes from low level to high level.

  In FIG. 15, first, in step S <b> 10, the CPU 45 reads the instrument type detected by the detection ports PO <b> 0 to PO <b> 3 from the input ports D <b> 0 to D <b> 7 via the expansion I / O port 88 as designated data. Thereafter, the process proceeds to step S15.

  In step S15, the CPU 45 retrieves designated data from the data table 78 stored in the ROM 47 based on the data read in step S10. In this example, since the voltage appearing at the detection port P03 changes from the low level to the high level as described above, the CPU 45 detects the data “1” from the input port D3 corresponding to the detection port P03. As a result, the CPU 45 acquires designated data X8H corresponding to the case where the data of the input port D3 is “1” and the data of the other input ports D0, D1, and D2 is “0” from the data table 78. . The designation data X8H designates deletion of MIDI data # 4 that designates the MIDI sound source of the electric guitar 4 as shown in the data table 78. When step S15 ends, the process proceeds to step S20.

  In step S20, the CPU 45 temporarily stores the designated data retrieved in step S15 (designated data X8H in this example) in the RAM 46. Thereafter, the process proceeds to step S25.

  In step S25, the CPU 45 determines whether or not the music selection by the user has been completed. For example, when the user inputs a song selection number of a song that the user wants to sing with the numeric keypad 68 of the remote controller 60, a number corresponding to the numeric keypad 68 is displayed each time the key is pressed, and the song selection number display unit 23 of the remote controller 60. Are displayed in sequence. Next, when the music selection button 69 is pressed after the last numeric keypad 68 is pressed, the music selection is completed. At the time of music selection, if the user wants to perform key control on the selected music together, the user gives an instruction using the flat keys 29 and 66 (or sharp keys 31 and 67). Such a key control instruction is also acquired in step S25 together with the music selection instruction. Until the music selection is completed, the determination in step S25 is not satisfied (step S25: NO), and a loop standby is performed. When the music selection is completed, the determination in step S25 is satisfied (step S25: YES), and the process proceeds to step S30.

  In step S30, the CPU 45 temporarily stores music selection number data indicating the music selection number in the RAM 46 corresponding to the music selection result in step S25, and includes TAB score data corresponding to the music selection number via the LAN board 50. A request signal for requesting transmission of the music data 100 is transmitted to the server 58 via the LAN line 15. As a result, the server 58 searches and reads the music data 100 including the TAB music data corresponding to the music selection number indicated in the request signal from a storage device (not shown), and reads the music data 100 that has been read out to the LAN line 15. Is transmitted to the control device 20 via. When step S30 ends, the process proceeds to step S35.

  In step S <b> 35, the CPU 45 receives the song data 100 including the TAB score data transmitted from the server 58 via the LAN line 15 via the LAN board 50. Thereafter, the process proceeds to step S40.

  In step S40, the CPU 45 temporarily stores the song data 100 received in step S40 in the RAM 49. Thereafter, the process proceeds to step S45.

  In step S45, the CPU 45 reads the designated data (designated data X8H in the above example) stored in the RAM 46 in step S20 described above. Thereafter, the process proceeds to step S50.

  In step S50, the CPU 45 starts reading the MIDI data 110 stored in the RAM 49 in step S40 described above. Thereafter, the process proceeds to step S55.

  In step S55, the CPU 45, based on the designation data read in step S45 (in this example, designation data X8H), the MIDI data read in step S50 and being processed at this time is the MIDI data designated by the designation data. It is determined whether the data (in this example, MIDI data # 4 designating the MIDI sound source of the electric guitar 4). If it is the specified MIDI data, the determination is satisfied (step S55: YES), and the process proceeds to step S60. If it is not the specified MIDI data, the determination is not satisfied (step S55: NO), and the process proceeds to step S65 described later.

  In step S60, the CPU 45 performs a minus one process for deleting the MIDI data to be processed at this time. Thus, when steps S50 to S105 are repeated as will be described later, only when the data including the MIDI data # 4 designating the MIDI sound source of the electric guitar 4 is read in step S50, the MIDI data # 4. Is deleted (see FIG. 6D described above). In the minus one process, instead of deleting the MIDI data to be processed, the data 118 for muting may be added as shown in FIG. As a result, it is possible to realize reproduction of karaoke music data in a minus one state excluding the electric guitar music part. When step S60 ends, the process proceeds to step S65.

  In step S <b> 65, the CPU 45 determines whether or not there is a change instruction (shift) of key control (hereinafter referred to as “keycon” as appropriate) of the music data 100 by the player of the electric guitar 4. The performer operates the flat key 66 of the remote control 60 (or the sharp key 29 of the control device 20) or the sharp key 67 of the remote control 60 (or the sharp key 31 of the control device 20) to shift the key of the song data 100 from the current state. If it is changed (changed in the flat direction or changed in the sharp direction), the determination in step S65 is satisfied (step S65: YES), and the process proceeds to step S70. If there is no instruction to change the key converter of the song data 100, the determination in step S45 is satisfied (step S45: YES), and the process proceeds to step S95 described later.

  In step S70, the CPU 45 determines whether or not the performer is playing (playing) the electric guitar 4 based on the input level of the performance signal input from the phone plug 4a of the electric guitar 4 via the phone jack 85. Determine. For example, the level of the input level of the performance signal is compared with a predetermined threshold value that can be considered that the performance signal is substantially input. If the input level of the performance signal is equal to or higher than the threshold value, the determination is satisfied (step S70: YES), and the process proceeds to step S95 described later. If the input level of the performance signal is less than the threshold value, the determination is not satisfied (step S70: NO), and the process proceeds to step S75.

  In step S75, the key amount shift amount (for example, the above-mentioned one-note reduction etc.) designated in step S65 is changed (= shift processing) with respect to the MIDI data read in step S50 by a known method. ). Of the MIDI data, MIDI data # 1 related to the electronic drum that is a percussion instrument system is excluded from the shift processing target. Thereafter, the process proceeds to step S80.

  In step S80, the CPU 45 shifts the TAB score data 160 included in the song data 100 to the minus side (or plus side) by the shift amount of the key control designated in the step S65, so that new TAB score data is obtained. Generate. Thereafter, the process proceeds to step S85.

  In step S85, the CPU 45 determines whether or not the new TAB score data generated in step S80 includes fingering data outside the playable range. If the new TAB score data includes fingering data (fingering position where no fret exists) outside the playable range as shown in FIG. 12B, for example, the determination in step S85 is satisfied. (Step S85: YES), the process proceeds to step S90. If the new TAB score does not include fingering data outside the playable range, the determination in step S85 is not satisfied (step S85: NO), and the process proceeds to step S95 described later.

  In step S90, the CPU 45 replaces the fingering data outside the playable range included in the new TAB score data generated in step S80 with playable fingering data giving the same pitch as described above. Then, another new TAB score data is generated. In this case, when there are a plurality of fingering data of different strings giving the same pitch, as described above with reference to FIGS. 13 and 14, among the plurality of fingering data, it is necessary for replacement. Replacement is performed using the fingering data that minimizes the moving distance to the other string, and the other TAB score data is generated. Thereafter, the process proceeds to step S95.

  In step S95, the CPU 45 incorporates the MIDI data 110 that has been read in step S50 and has undergone the processing in steps S55 to S75 (minus one processing or key conversion processing) into the CPU 45 via a sequencer (not shown). Is written in the MIDI sound source board 51 in accordance with the timer count. When step S95 is completed, the process proceeds to step S100.

  In step S100, the CPU 45 outputs a control signal to the MIDI sound source board 51, and causes the MIDI sound source board 51 to output a sound source signal corresponding to the MIDI data written in step S95. The sound source signal output from the MIDI sound source board 51 is output to the sound control circuit 52 and converted into a music signal that can be amplified by the amplifier 16, and the converted music signal is transmitted from the sound output terminal 41 to the amplifier 16. Is output. Also, the audio signal input from the microphones 17 and 18 is mixed with the music signal in the mixing circuit 9 built in the amplifier 16. At this time, the performance signal output from the phone plug 4a of the electric guitar 4 is input to the mixing circuit 9 via the musical instrument connection board 8, the output terminal 87, and the control device 20, and is mixed with the audio signal and the music signal. The The mixed signal thus mixed is amplified by an amplifier circuit (not shown) built in the amplifier 16 and then output to the speaker 11 and the speaker 12 and reproduced by both speakers. When step S100 ends, the process proceeds to step S105.

  In step S105, the CPU 45 outputs a control signal to the monitors 13 and 14, and if the new TAB score data generated in step S80 or the new TAB score data cannot be played, it is replaced in step S90. Another TAB score data that can be played is displayed on the monitors 13 and 14. Thereafter, the process proceeds to step S110.

  In step S110, the CPU 45 determines whether or not the reproduction of the music data 100 has been completed (in other words, whether or not the reading of the MIDI data in step S70 has been completed up to the last MIDI data of the music data 100). If the reproduction of the song data 100 is finished, the determination is satisfied (step S110: YES), and this flow is finished. Until the reproduction of the song data 100 is completed, the determination is not satisfied (step S110: NO), the process returns to step S50, and the procedure of steps S50 to S105 is repeated. During the repetition, the MIDI data # 4 included in the MIDI data read in step S50 is not written to the MIDI sound source board 51, and therefore a sound source signal indicating the sound of the electric guitar is not output from the MIDI sound source board 51. . As a result, the karaoke music data is reproduced in a minus one state excluding one desired musical instrument performance part (a performance part of the electric guitar 4 in this example). Thereby, the user who is the player of the electric guitar 4 can play and enjoy the removed electric guitar performance part by himself according to the karaoke music reproduced in the minus one state. That is, the user can play the electric guitar 4 while causing the karaoke device 10 to reproduce normal karaoke music data (karaoke performance). In this case, as described above, since the sound of the electric guitar performance part is not reproduced in the karaoke performance, the performance sound of the electric guitar 4 performed by the performer is not canceled by the sound emitted from the speakers 11 and 12. In addition, since the TAB score data is displayed on the monitors 13 and 14 together with the lyrics, the user can easily play the electric guitar 4 in accordance with the song to be played in the minus one state while viewing the TAB score data. Can play.

  In the above flow, the procedure of step S65 functions as the key input means described in each claim, the procedure of step S70 functions as the performance determination procedure, and the procedure of step S80 functions as the TAB score shifting means. The procedure of step S85 functions as a TAB score determination unit, the procedure of step S90 functions as a TAB score replacement unit, and the procedure of step S100 functions as a karaoke piece reproduction unit.

  In addition, when the above-mentioned repetition after the start of the reproduction of the karaoke music data in step S100, the performer shifts the key of the music data 100 from the current state (the state set before the start of the reproduction) as described above. Even if there is (step S65: YES), if the performer is not playing the electric guitar 4 (step S70: NO), the performer does not shift the key of the song data 100 from the current state (step S65: NO). Similarly to the above, the keycon shift process in step S75, the TAB score shift process in step S80, the TAB score replacement process in step S90, and the like are not executed. That is, the key setting of the music data 100 at that time is maintained. The flow of the above procedure of the flow executed by the CPU 45 functions as control means described in each claim.

  As described above, in the karaoke apparatus 10 according to the present embodiment, the TAB music data of the guitar performance part is associated with the karaoke music data in advance, and the karaoke music data is reproduced on the monitors 13 and 14 when the karaoke music data is reproduced. A TAB score is displayed. At that time, when a key control instruction to the plus side (or minus side) is input by the user, the TAB score data associated with the karaoke music data as described above is automatically added to the plus side (or minus side). ) To become new TAB score data. Then, if the generated new TAB score data includes fingering data that is outside the playable range of each string, the fingering data is replaced with another fingering data that gives the same pitch, TAB score data is generated, and the replaced TAB score data is displayed on the monitors 13 and 14. This makes it possible to reliably display a TAB score that can be actually played by the user who plays the electric guitar 4 regardless of what key control instruction is given to the karaoke song data.

  Moreover, the above-mentioned key control instruction is possible not only before the start of reproduction of karaoke music data but also after the start of reproduction. At this time, after the reproduction is started, the new TAB score data generated as described above (or another TAB score data replaced as described above) is displayed on the 13th and 14th stages of the monitor. The user who plays the electric guitar 4 is playing the electric guitar 4 while viewing the displayed data. Therefore, when performing such a performance, if the TAB score is suddenly shifted again or replaced as described above by a key control instruction again, the user who is playing the electric guitar 4 You may be confused and unable to play.

  Therefore, in the present embodiment, whether or not a performance signal from the electric guitar 4 is input in step S70 of FIG. 15 when a key control instruction is input after the start of reproduction of karaoke song data as described above. Determined. If a performance signal is input, the process proceeds from step S70 to step S95 (by not executing step S75 or step S80), thereby substantially invalidating the key control instruction and starting playback. The previously set key value and TAB score data value are maintained. As a result, the generation of new TAB score data in step S80, the determination in step S85, and the generation of another TAB score data in step S90 are not executed, and the TAB score changes suddenly during the performance. There is no need to do it. In this case, the key control instruction is accepted but not reflected in the reproduction content. Alternatively, the key control instruction itself may not be accepted. As a result, once the reproduction of karaoke music data is started, the user can play the electric guitar 4 with confidence while watching the TAB music.

  As described above, according to the present embodiment, the user who plays the electric guitar 4 can actually perform the performance regardless of the key control instruction given to the karaoke piece data at any timing. Possible TAB music can be displayed reliably. As a result, user convenience is improved.

  On the other hand, even after the reproduction of karaoke song data, before the user starts playing the electric guitar 4, or the performance part of the electric guitar 4 is closed (non-performance section) between songs. In some cases. In such a case, there is a high possibility that the user can sufficiently follow even if the above-described TAB score shift or replacement is performed again. Therefore, in the present embodiment, in particular, when the key control instruction is input during the reproduction of karaoke song data, and when it is determined in step S70 that the performance signal from the electric guitar 4 is not input, the above-described case. The above-described processes corresponding to the newly input key control instruction are executed without substantially invalidating the key control instruction. That is, generation of new TAB score data in step S80 described above, determination in step S85, generation of another TAB score data in step S90, and the like are executed. Thus, in response to the key control instruction after the reproduction of the karaoke song data, for example, the user who performs the singing changes to a key that is easy to sing, and the user who performs is surely playing the electric guitar 4 while watching the TAB score. Can do.

  In addition, in the above, the arrow shown in FIG. 3 shows an example of the signal flow, and does not limit the signal flow direction.

  Further, the flowchart shown in FIG. 15 does not limit the present invention to the procedure shown in the above-described flow, and the procedure may be added / deleted or the order may be changed without departing from the spirit and technical idea of the invention. Good.

  In addition to those already described above, the methods according to the above-described embodiments and modifications may be used in appropriate combination.

  In addition, although not illustrated one by one, the present invention is implemented with various modifications within a range not departing from the gist thereof.
