  In a karaoke apparatus for reproducing karaoke music data, a technique for reproducing karaoke music data including a plurality of musical instrument performance parts has already been proposed (for example, see Patent Document 1). A user who is a musical instrument player can play the musical instrument performance part in accordance with the reproduced karaoke music piece to practice the musical instrument or enjoy an ensemble of the entire karaoke musical piece.

JP-A-8-30284

  By the way, for example, in order to make it easy for beginners and unfamiliar people to play a guitar such as an electric guitar, an acoustic guitar, and a classical guitar, a capostat is sometimes used. When the fingering position of each string when the desired chord is played by the guitar is complicated, the capo tasting is performed when the desired chord is played by changing the length of each string between the guitar necks (see FIG. 1). By changing the fingering position to an uncomplicated fingering position, the fingering position is simplified and the fingering burden on the performer is reduced. The performer can enjoy playing the guitar easily and easily by attaching the capotast to an appropriate position of the guitar neck.

  Here, even when a user enjoys playing a musical instrument together with the karaoke apparatus as in the above-described prior art, there may be a case where the user wants to play the guitar with the capotast attached to the guitar neck as described above. However, since the position of capotast in the guitar neck is usually set for each song, when a plurality of karaoke songs are reserved, the capotast position may differ between one karaoke song and another karaoke song. possible. In this case, after the user enjoys playing the guitar of the one karaoke piece by wearing the capotast at a certain position set for one karaoke piece, another user set to the next karaoke piece is set. Capotast needs to be installed in position. In other words, it is necessary to change the mounting position by removing the capotast, moving the removed capotast to another position, and then reattaching the capotast at the moved new position. In general, Capotast is a structure that is firmly attached to the guitar neck so that multiple strings stretched on the guitar can be pressed without slipping, so it takes a lot of effort to attach, remove and move . In particular, the greater the movement distance on the way from removal to remounting, the greater the burden on the user of the entire mounting position changing operation.

  The objective of this invention is providing the karaoke apparatus which can reduce the labor burden of the mounting position change operation | work of the capotast between music at the time of several karaoke music reproduction.

  In order to achieve the above object, the first invention is a reservation receiving means capable of receiving a reservation of karaoke music by a user, and a plurality of musical instrument performances prepared for the karaoke music and including a guitar instrument performance part. Karaoke music data that is composed of parts and is associated with capotast position data of the guitar instrument performance part can be played back according to the playback of the karaoke music data in the karaoke music data playback means and the karaoke music data playback means. When the reservation means accepts the reservation of a plurality of the karaoke songs, the display means for displaying the capotast position data corresponding to the karaoke music data, a plurality of the karaoke songs corresponding to each of the plurality of karaoke songs The reproduction order of the karaoke music data reproduction means of the karaoke music data is set to the adjacent order. One of the differences of the karaoke each other of the capo position data in the music data determined to be or minimizing the 0, characterized by having a a reproduction order determination means.

  In the first invention of this application, when a reservation for the karaoke song of the user is received by the reservation receiving means, karaoke music data including the guitar instrument performance part is played back by the karaoke music playing means in response to the reservation. At that time, the capostat position data of the guitar instrument performance part is associated with the karaoke music data in advance, and the capostat position data is displayed by the display means when the karaoke music data is reproduced. The capo tasto simplifies the fingering position and reduces the fingering burden on the performer when the fingering position on each string when a desired chord is played by the guitar is complicated. The user can easily and easily enjoy playing the guitar in accordance with the karaoke music data reproduced from the reproducing means by attaching the capotast to the position indicated by the displayed capotast position data on the guitar neck. it can.

  Here, since the position of the capotast in the guitar neck is normally set for each song, when a plurality of karaoke songs are reserved, the capotast position differs between one karaoke song and another karaoke song There can be. In this case, after the user enjoys playing the guitar of the one karaoke piece by wearing the capotast at a certain position set for one karaoke piece, another user set to the next karaoke piece is set. Capotast needs to be installed in position. In other words, it is necessary to change the mounting position by removing the capotast, moving the removed capotast to another position, and then reattaching the capotast at the moved new position. In general, Capotast is a structure that is firmly attached to the guitar neck so that multiple strings stretched on the guitar can be pressed without slipping, so it takes a lot of effort to attach, remove and move . In particular, the greater the movement distance on the way from removal to remounting, the greater the burden on the user of the entire mounting position changing operation.

  Therefore, in the first invention of the present application, when a plurality of karaoke songs are reserved as described above, the reproduction order determination means can reduce the labor burden of the user so that the plurality of karaoke songs data can be reduced. Determine the playback order. That is, the order is determined so that the capotast position data of the two karaoke music data in the adjacent order are the same (difference is 0) or the difference is minimized. As a result, the plurality of karaoke songs are arranged in such an order that there is no change in the position of the capo tasto when one song is finished and the next song is moved, or the moving distance is minimized. Accordingly, it is possible to reduce the labor burden of the capotast mounting position changing operation performed by the user between the above-described songs at the time of reproducing the plurality of karaoke songs, and the convenience of the user can be improved.

  In a second aspect based on the first aspect, the reproduction order determining means compares reserved music data to be played first with reservation music data after that among the reservations of the karaoke music. The playback order in the karaoke music playback means is determined for the subsequent reserved music data so as to continuously play back a plurality of karaoke music data having the same capotast position data. .

  Thus, when the playback order is determined for the karaoke music pieces for which the reservation has been accepted, if there are a plurality of karaoke music pieces having the same specific capo tast position, the plurality of karaoke music pieces are played back continuously. As a result, while the plurality of karaoke songs are continuously played back, the above-described mounting position changing operation is not necessary, so that the convenience for the user can be reliably improved.

  According to a third aspect of the present invention, in the first or second aspect of the invention, the playback order determination means is the karaoke already played by the karaoke music playback means when the reservation reception means receives a reservation for the plurality of karaoke songs. If there is music data, the adjacent 2 in the karaoke music data group including the karaoke music data being reproduced and the plurality of karaoke music data corresponding to each of the received karaoke music data. The reproduction order of the plurality of karaoke song data is determined so that a difference between the capotast position data in one karaoke song data is 0 or minimized.

  Thus, when the playback order determination means determines the playback order of the karaoke song data, not only the capotast position of each of the reserved karaoke songs but also the current capotast position corresponding to the currently played karaoke song is taken into account. Thus, it is possible to reduce the labor burden in the mounting position changing operation. This result can further improve the convenience for the user.

  According to the present invention, when reproducing a plurality of karaoke songs, it is possible to reduce the labor burden of the work for changing the mounting position of the capostat between songs.

<Features of this embodiment>
In the above basic configuration, the feature of the present embodiment is that when a reservation for a plurality of karaoke pieces including a guitar instrument performance part is accepted, it is possible to reduce the labor burden of the user who performs the guitar replacement of the capotast 92 described above. In addition, the reproduction order of a plurality of karaoke song data is to be determined. Hereinafter, the details will be described in order.

<Indication of capotast position>
As described above, the capostat 92 is attached to the neck 90 of the electric guitar 4. The capostat 92 is generally used when a desired chord is played by a guitar instrument such as an electric guitar, an acoustic guitar, a classic guitar, or a guitar instrument having a fret such as a bass guitar, ukulele, mandolin, or banjo. When the position is complicated, the fingering position is changed to a simplified performance key that is easy to play, and the fingering burden on the performer is reduced.

  In the present embodiment, in order to reduce the fingering burden on the performer, when the karaoke pieces are played, the monitor position suitable for playing the guitar instrumental performance part of the karaoke pieces is the monitor 13,14. Is displayed.

In FIG. 9, the example of a display displayed on the monitors 13 and 14 according to reproduction | regeneration of karaoke music is shown. In this example, as shown in FIG. 9A, the original music key when performing without attaching the capostat 92 to the neck 90 of the electric guitar 4 is F ^# m. Then, the chord progression of the song corresponding to the lyrics “if you don't even say that word” becomes F ^# m → C ^# m7 → Dadd9 → C ^# m7 → ..., for example, a beginner plays on the electric guitar 4 The code is relatively difficult to finger. On the other hand, when the capostat 92 is attached to the two frets of the neck 90 of the electric guitar 4, as shown in FIG. 9B, the apparent performance key of the above-mentioned song to be played by the user (player) is shown. Is changed to Em, and the chord progression (apparently) corresponding to the above lyrics after changing the performance key “I have to say that word” becomes Em → Bm7 → Cadd9 → Bm7 →. Simplified fingering can be achieved with a low code.

<Capo tasto table>
In the present embodiment, the capotast table 80 is used to perform the display as described above. An example of this capo last table 80 is shown in FIG.

As shown in FIG. 10, in this capo last table 80, the correspondence relationship between the performance key of the original music, the capo last position of the electric guitar, and the (apparent) performance key after using the capoast is tabulated. . As shown in the drawing, in this table 80, a suitable capotast position is uniquely set for the performance key of the original music. In this example, the capotast position indicates the position of the fret to which the capotast is to be attached by the number of frets (note that the fret “0” indicates that the capotast is unnecessary). According to the above-described example, when the original music key is “F ^# m”, the capo last position is determined to be “2”. As a result, as described above, the apparent performance key that the performer should perform is “Em”.

  By using such a capostat table 80, for example, when the performance key of the original music is acquired from the music data 100, the mounting position of the corresponding capostat 92 is uniquely determined, and the mounting position is changed by the mounting. Then, the apparent performance keys, such as low chords, which are regarded as simple fingerings, are displayed on the monitors 13 and 14 as described above. The capo last table 80 is stored in advance in the ROM 47 of the control device 20, for example. Then, based on the capo last table 80 read from the ROM 47 during the reproduction of the karaoke music, the capo last position is displayed on the monitors 13 and 14 according to the reproduction of the karaoke music.

<Moving the position of capotast when playing multiple songs>
Here, normally, the position of the capostat 92 to the guitar neck is individually set for each music piece. Therefore, when a plurality of karaoke songs are reserved in the karaoke apparatus 10, one karaoke song and another karaoke song may have different capotast positions on the neck 90 of the electric guitar 4. In this case, as it is, the user (performer) mounts the capoast 92 at a certain position set for one karaoke piece and enjoys playing the electric guitar 4 of the one karaoke piece. It is necessary to attach the capostat 92 to another position set for the karaoke piece. That is, it is necessary to perform a mounting position changing operation of removing the capostat → moving the removed capostat 92 to another position → remounting the capostat 92 at the moved new position. In general, Capotast is a structure that is firmly attached to the guitar neck so that multiple strings stretched on the guitar can be pressed without slipping, so it takes a lot of effort to attach, remove and move .

  Therefore, in the present embodiment, when a plurality of karaoke pieces are reserved by the above-described numeric keys 21, 68, the music selection buttons 22, 69, etc., it is possible to reduce the labor burden of changing the capo tast 92 of the user who plays the guitar. Thus, the reproduction | regeneration order of several karaoke music data is determined.

<Reserved song arrangement processing>
FIG. 11 shows the processing contents of the reserved song arrangement process executed in the control device 20 in order to determine the reproduction order of the plurality of karaoke song data.

  In FIG. 11, this flow is a process in which a reservation for a karaoke song including a guitar instrument performance part is newly received from a user, and is not currently being played or is being prepared for playing (hereinafter simply referred to as “current song” as appropriate). Is started when there are a plurality of reserved songs (hereinafter simply referred to as “reserved songs”). Therefore, in addition to the current song, this flow is started when a plurality of new songs are reserved in addition to the current song, and in addition to the current song, one or more additional songs are added next. It is started in any of the cases where the total number of reserved songs becomes a plurality of songs by making a reservation, and when one or more additional songs are reserved in the state where there are a plurality of reserved songs. Then, in the state where there is a reserved song (which has not been played and not in preparation for playback) whose playback order has already been determined in the procedure of steps S10 to S105 described later in this flow, one or more new songs Is added, all the reserved songs including the one or more additional songs are subjected to the arrangement process again by the procedure of steps S10 to S105 described later. In addition, the function of CPU45 of the control apparatus 20 which receives the reservation of the karaoke music from the above-mentioned user functions as a reservation reception means as described in each claim.

  In FIG. 11, first, in step S <b> 10, the CPU 45 of the control device 20 downloads the original performance key (N) from the reserved music data 100 downloaded from the server 58 and stored in the RAM 49. Key information representing the original music key) is fetched. Here, N is an integer of 2 or more. Note that the key information of each song may be acquired in advance in the song data 100. Alternatively, the key information may be detected from MIDI data by a known method. When detecting from the MIDI data, the chord at the end of the performance in the MIDI data 110 (which is often a so-called result code) may be detected as a performance key, or the chord at the performance start portion may be detected as the performance key. You may detect as. The captured key information is stored in, for example, the RAM 49 of the control device 20. When step S10 ends, the process proceeds to step S15.

  In step S15, the CPU 45 calculates the capo last position (fret position) for the reserved music N songs from the key information for the reserved music N songs fetched in step S15 with reference to the capo last table 80 of FIG. To do. That is, as described above, the song data 100 and the capo last position data are associated with each other via the capo last table 80. The capo last position data may be included in the song data 100 in advance, instead of being calculated from the key information of the song using the capo last table 80. In this case, the capo last position data is associated with the music data 1000 in a form incorporated in the music data 100. In this case, the capo last table 80 is not necessary. Thereafter, the process proceeds to step S20.

  In step S20, the CPU 45 sets a variable n representing the processing order when the N reserved songs are processed in a predetermined order (for example, the order of reservation acceptance, the order of song names, the order of singer names, etc.) to n = 1. After initialization, the process proceeds to step S25.

  In step S25, the CPU 45 determines whether or not the capotast position calculated in step S15 for the n-th reserved song is the same position (ie, the same fret) as the capotast position for the current song. Although not clearly shown in the procedure of this flow, at this point, the current song also has the capotast from the key information of the obtained song by the same method as in steps S10 and S15 as described above. The capotast position is determined using the table 80 and displayed on the monitors 14 and 15 as described above. Therefore, in this step S25, the capo last position of the current song is compared with the capo last position of the nth reserved song.

  If the n-th reserved song has the same position as that of the current song (ie, if the deviation between the n-th reserved song and that of the current song is ± 0), step S25. (Step S25: YES), the process proceeds to step S30. Hereinafter, a song having the same position as the current song is called “a song at the same position”. On the other hand, when the capo last position of the n-th reserved song is different from the capo-tast position of the current song (that is, when the deviation between the n-th reserved song and the current song is not 0) ) Is not satisfied (step S25: NO), the process proceeds to step S45 described later. It should be noted that a song having a different position from the current song in this manner is hereinafter referred to as “a song at a different capotast position”.

  In addition, as described above, the position of the capostat 92 of each song is represented by “2” and “4” depending on the number of frets of the neck 90 to which the capostat 92 is attached. For convenience, the position of capotast is represented as “0”.

  In step S30, the CPU 45 determines that another reserved song whose playback order has already been set (set) before the n-th song currently being processed (hereinafter referred to as “other reserved song that has been set” as appropriate). In other words, it is determined whether or not there is a song (= a song at the same capostat position) in which the other reserved song has the same capostat position as the current song. If there is no song at the same capotast position among the other reserved songs that have been set (that is, if all the other reserved songs that have been set are songs at a different capotast position), the determination is not satisfied (step (S30: NO), the process proceeds to step S35. On the other hand, if there is a song at the same position in the other reserved songs that have been set, the determination is satisfied (step S30: YES), and the routine goes to step S40.

  In step S35, the CPU 45 sets the playback order of the n-th reserved music in the order next to the current music. An example of the set result in step S35 is shown in FIG.

  In FIG. 12A, a new set song 132 represents the song data of the nth reserved song for which the playback order has been newly set by the processing of step S35, and the already set song 131 is the playback of the new set song 132. It represents the song data of other reserved songs for which the playback order has already been set before the order set time. The numerical values attached to the frames representing the data of the new set song 132 and the already set song 131 indicate the deviations in the capotast position of the new set song 132 and the already set song 131 from the current song 130, respectively. Therefore, the value of the deviation is “± 0” in the music at the same capostat position, and the value of the deviation is a value other than “± 0” in the music at the different capostat position. Note that, in this example, the case where the position of the reserved music capotast is located on the plus side where the number of frets increases (or is at the same position) with respect to the current music capotast position will be described as an example. Needless to say, the present invention can also be applied to a case where the value is on the minus side where the value decreases. Also, a numerical value added outside the frame between two adjacent songs, for example, the new set song 132 and the already set song 131, indicates the difference in the capotast position between the new set song 132 and the already set song 131.

  In the example shown in FIG. 12A, the new set music 132 has a capotast position deviation of ± 0. There are two already-set songs 131, one with a deviation of +1 for the capostat position and one with a deviation of +2 for the capostat position. Since the deviation of the capo last position of the new set song 132 is smaller than that of any of the already set songs 131, the playback order of the new set song 132 is set to the next order of the current song 130 in step S35. .

  When step S35 is completed as described above, the process proceeds to step S100 described later.

  On the other hand, in step 40, since there is a song at the same position in the other reserved music that has been set, the CPU 45 changes the playback order of the nth reserved music to the other same capotest that has already been set. Set it at the end of the song at the position. An example of the set result of step S40 is shown in FIG.

  In FIG. 12 (b), in this example, the set music 131 has two cases where the deviation of the capotast position is ± 0 and one of the deviations of the capotast position is +1 and +2, respectively. There are four. The new set song 132 has a deviation of ± 0 on the capostat position. Therefore, the new set song 132 is added to the end of the two already-set songs 131 that have the capotast position deviation of ± 0. Is set. It should be noted that the set positions of the two already-set music pieces 131 and 131 with the deviation of the capotast position +1 and +2 are changed so as to follow the new set music piece 131 in the order of the smallest deviation of the capotast position.

  When step S40 is completed as described above, the process proceeds to step S100 described later.

  On the other hand, in step S45, where the determination in step S25 is not satisfied and the process proceeds to step S45, the CPU 45 determines that the other reserved music that has been set is different from the current music (= different from the current music). It is determined whether or not there is a song at the position of capotast. If there is a song at the different capo last position among the other reserved songs that have been set, the determination is satisfied (step S45: YES), and the routine goes to step S65 described later. On the other hand, if there is no song at the different capo last position among the other reserved songs that have been set, the determination is not satisfied (step S45: NO), and the process proceeds to step S50. In this case, only the n-th song currently being processed is a song at a different capo last position.

  In step S50, as in step S30, the CPU 45 determines whether there is a song at the same position in the other reserved songs that have been set. If there is a song at the same position in the other reserved songs that have been set, the determination is satisfied (step S50: YES), and the routine goes to step S55. If there is no song at the same position in the other reserved songs that have been set, the determination is not satisfied (step S50: NO), and the process proceeds to step S60.

  In step S55, the CPU 45 sets the playback order of the n-th reserved music in the order next to the last of the music at the other set-up position. An example of the set result of step S55 is shown in FIG.

  In FIG. 12C, the already-set music piece 131 is a music piece at the same position where the deviation of the position of the capostat is ± 0. The new set song 132 is set in the next order of the already set song 131 that is a song at the same capostat position because the deviation of the capostat position is +1 and the song is at a different capostat position.

  When step S55 ends, the process proceeds to step S100 described later.

  On the other hand, in step S60, the CPU 45 sets the reproduction order of the n-th reserved music in the order next to the current music. An example of the set result in step S60 is shown in FIG.

  In FIG. 12D, the new set song 132, which is the nth reserved song to be processed at this time, is the only reserved song at this time as a result of the determination in step S45 and step S50 not being satisfied. (There is no existing set song), and the song is in a different capotast position. In this example, in the new set music 132, the deviation of the capo last position is +1. In addition to the current song 130, there is no song that has already been set at the different capostat position or at the same position, so the new set song 132 is set in the next order of the current song 130.

  When step S60 ends, the process proceeds to step S100 described later.

  On the other hand, in step S65, where the determination in step S25 is satisfied and the process proceeds to step S65, the CPU 45 is the other reserved music that has already been set, and the deviation of the capo last position of the other reserved music is the current processing target. It is determined whether there is a song having the same deviation as the above-described deviation of the capotast position of the nth reserved song. When there is a song in which the deviation of the capostat position is the same as that of the nth reserved song among the other reserved songs that have been set (that is, the position of the capotast in the other reserved songs that have been set) And when the difference between the n-th reserved music and the capo last position is 0), the determination is satisfied (step S65: YES), and the process proceeds to step S95 described later. On the other hand, when there is only a song in which the deviation of the capotast position is different from the deviation of the capotast position of the nth reserved song in the other reserved music that has been set (that is, the position of the capotast in the other reserved music that has been set) Is not satisfied (step S65: NO), the process proceeds to step S70.

  In step S70, the CPU 45 determines whether or not there is a song that is another reserved song that has been set, and the deviation of the capotast position is smaller than the deviation of the capotast position of the nth reserved song. To do. If all the deviations in the set other reserved songs are larger than the deviation of the n-th reserved song, the determination is not satisfied (step S70: NO), and the process proceeds to step S75. On the other hand, if there is a tune whose deviation is smaller than the deviation of the nth reserved tune among the other reserved tunes that have been set, the determination is satisfied (step S70: YES), and the process proceeds to step S90 described later. Move.

  In step S75, the CPU 45 determines whether there is a song at the same position in the other reserved songs that have been set, as in steps S30 and S50. If there is no song at the same position in the other reserved songs that have been set, the determination is not satisfied (step S75: NO), and the process proceeds to step S80. If there is a song at the same position in the set other reserved songs, the determination is satisfied (step S75: YES), and the process proceeds to step S85 described later.

  In step S80, the CPU 45 sets the playback order of the n-th reserved song in the order next to the current song. An example of the set result of step S80 is shown in FIG.

  In FIG. 12 (e), the new set tune 132 is a tune at the capotast position with a deviation of +1. However, the already-set music 131 has only one with a capotast position deviation of +2 and two with a deviation of +3, and there is no music with the same capotast position. The new set music 132 is set in the next order of the current music 130 because there is no existing set music 131 at the same position.

  When step S80 ends, the process proceeds to step S100 described later.

  On the other hand, in step S85, the CPU 45 sets the reproduction order of the n-th reserved music by adding it to the end of the other music set at the same capo last position. An example of the set result of step S85 is shown in FIG.

  In FIG. 12 (f), in this example, the new set song 132 is a song at a different capo last position with the above deviation of the capo last position being +1. The already-set music piece 131 has two music pieces at the same capostat position where the deviation of the capostat position is ± 0, and one music piece at a different capostat position where the deviations are +2 and +3. As a result, the new set song 132 is interrupted in the form of being added to the end of the already set song 131 at the same position, and the playback order is set.

  When step S85 is completed as described above, the process proceeds to step S100 described later.

  In step S90, the CPU 45 sets the reproduction order of the n-th reserved song in the order next to the last of the other reserved songs that have been set, the deviation being smaller than the deviation of the n-th reserved song. To do. An example of the set result of step S90 is shown in FIG.

  In FIG. 12 (g), in this example, the new set music 132 is a music at a different capostat position where the deviation of the capostat position is +2. In the already-set music 131, there are two ones with a deviation of +1 in capotast position, one with +2, and two with +3. Of these, two already set songs 131 and 131 with a deviation of +1 have a smaller deviation than the new set song 132. Therefore, the new set music 132 is set in the order next to the last of the already set music 131 and 131 having the small deviation.

  When step S90 ends, the process proceeds to step S100 described later.

  On the other hand, in step S95, the CPU 45 adds the playback order of the n-th reserved song to the end of the other reserved songs that have been set, the deviation of which is the same as the deviation of the n-th reserved song. set. An example of the set result of step S95 is shown in FIG.

  In FIG. 12 (h), in this example, the new set music 132 is a music at a different capotast position where the deviation of the capotast position is +3. In the already-set music 131, the deviation of the capotast position is +1, two are +3, three are +4, and one is +5. Of these, three already set songs 131 with a deviation of +3 have the same deviation as the new set song 132. Therefore, the new set music 132 is set by adding to the end of the three already set music 131, 131, 131 having the same deviation of +3.

  When step S95 ends, the process proceeds to step S100 described later.

  In step S100 transferred from step S35, step S40, step S55, step S60, step S80, step S85, step S90, and step S95, the CPU 45 adds 1 to n, and then proceeds to step S105.

  In step S105, the CPU 45 determines whether n has reached N. If n has not reached N (n <N), the determination is not satisfied (step S105: NO), the process returns to step S20, and the same procedure is repeated. If n has reached N (n = N), the determination is satisfied (step S105: YES), and this flow ends.

  In the above, the whole procedure of step S10 to step S105 functions as a reproduction order determination unit described in each claim.

<Music playback process>
FIG. 13 shows the processing contents executed by the CPU 45 when the karaoke apparatus 10 plays the music. In FIG. 13, for example, when the user of the karaoke device 10 presses the power button 39 of the control device 20 to turn on the power of the control device 20, this flow is started in conjunction with the flow of FIG. 11. That is, the flow of FIG. 13 is performed in parallel with the flow of FIG. 11 described above. Such concurrent processing can be performed by one control device by a known method similar to “multitask processing”, which is often performed by an OS of a computer, for example. The power of the amplifier 16, the musical instrument connection board 8, and the monitors 13 and 14 is started up in conjunction with the start-up of the control device 20. 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. 13, first, in step S <b> 115, the CPU 45 reads the instrument type detected by the detection ports PO <b> 0 to PO <b> 3 as designated data from the input ports D <b> 0 to D <b> 7 via the expansion I / O port 88. Thereafter, the process proceeds to step S120.

  In step S120, the CPU 45 retrieves designated data from the data table 78 stored in the ROM 47 based on the data read in step S115. 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. . As shown in the data table 78, the designation data X8H designates deletion of MIDI data # 4 that designates the MIDI sound source of the electric guitar. When step S120 ends, the process proceeds to step S125.

  In step S125, the CPU 45 temporarily stores the designated data (designated data X8H in this example) retrieved in step S120 in the RAM 46. Thereafter, the process proceeds to step S130.

  In step S130, the CPU 45 specifies the reserved music in the order to be reproduced next in accordance with the reproduction order of the reserved music set in the reserved music arrangement process of FIG.

  Thereafter, the process proceeds to step S200, and after tuning processing of the guitar instrument (in this example, the electric guitar 4) is performed using the internal tuner 93, the process proceeds to step S135. Note that the tuning process in step S200 will be described later with reference to FIG.

  In step S135, the CPU 45 temporarily stores the song number data of the reserved song specified as the next playback order in step S130 in the RAM 46 and transmits the song data 100 corresponding to the song number via the LAN board 50. Is transmitted to the server 58 via the LAN line 15. As a result, the server 58 retrieves and reads the song data 100 corresponding to the song number indicated in the request signal from a storage device (not shown), and the read song data 100 is transmitted to the control device via the LAN line 15. 20 to send. When step S135 is completed in this way, the process proceeds to step S140.

  In step S140, the CPU 45 receives the music data 100 transmitted from the server 58 via the LAN line 15 via the LAN board 50. Thereafter, the process proceeds to step S145.

  In step S145, the CPU 45 temporarily stores the music data 100 received in step S140 in the RAM 49. Thereafter, the process proceeds to step S150.

  In step S150, the CPU 45 reads the designation data (designation data X8H in the above example) stored in the RAM 46 in step S145. Thereafter, the process proceeds to step S155.

  In step S155, the CPU 45 starts reading the MIDI data 110 stored in the RAM 49 in step S145 described above. Thereafter, the process proceeds to step S160.

  In step S160, the CPU 45 reads out the MIDI data read in step S155 based on the designation data read in step S150 (designation data X8H in this example) and is the processing target at this point in time. 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 S160: YES), and the process proceeds to step S170. If it is not the specified MIDI data, the determination is not satisfied (step S160: NO), and the process proceeds to step S175 described later.

  In step S170, the CPU 45 deletes the MIDI data to be processed at this time. Thus, when steps S155 to S185 are repeated as will be described later, the MIDI data # 4 only when the data including the MIDI data # 4 designating the MIDI sound source of the electric guitar 4 is read in step S155. Is deleted (see FIG. 6D described above). Instead of deletion, data 118 for muting may be added as shown in FIG. 6 (e). 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 S170 ends, the process proceeds to step S175.

  In step S175, the CPU 45 sends the MIDI data 110, which has been read in step S155 and then processed in steps S160 to S170, to the MIDI tone generator board 51 according to the count of the timer built in the CPU 45 via a sequencer (not shown). Write to. When step S175 ends, the process proceeds to step S180.

  In step S180, 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 S175. 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 S180 ends, the process proceeds to step S185.

  In step S185, the CPU 45 determines whether or not the reproduction of the music data 100 has ended (in other words, whether or not the reading of the MIDI data in step S155 has been completed up to the last MIDI data of the music data 100). Until the reproduction of the music data 100 is completed, the determination is not satisfied (step S185: NO), the process returns to step S155, and the same procedure is repeated. When the reproduction of the song data 100 ends, the determination is satisfied (step S185: YES), and the process proceeds to step S190.

  In step S190, the CPU 45 determines whether or not the reproduction of all reserved songs reserved by the user has been completed. The determination is not satisfied until the reproduction of all reserved songs is completed (step S190: NO), the process returns to step S130 and the same procedure is repeated. If the reproduction of all reserved songs is finished, the determination is satisfied (step S190: YES), and then this flow is finished.

  In the above, the procedure of the step S180 functions as the karaoke piece reproducing means described in each claim.

<Tuning process>
Next, the tuning process in step S200 will be described with reference to FIG. As described above, this tuning process is performed by the CPU 45 controlling the internal tuner 93. In FIG. 14, first, in step S210, the CPU 45 initializes a variable K representing the string number of the guitar instrument (in this example, the electric guitar 4) to K = 1. Thereafter, the process proceeds to step S215.

  In step S 215, the CPU 45 outputs a control signal to the monitors 14 and 15 to display a guidance display such as “Do you want to tune?” On the monitors 14 and 15. Thereafter, the process proceeds to step S220.

  In step S <b> 220, the CPU 45 determines whether or not a selection operation for tuning by a user has been performed, for example, using an appropriate button of the remote controller 60. The user intends to tune the electric guitar 4 by looking at the guidance display on the monitors 14 and 15 in the above step S215 (especially when the capostat 92 is attached, the pitch is likely to be distorted and tuning may be necessary frequently). ) If the above selection operation is performed, the determination in step S220 is satisfied (step S220: YES), and the process proceeds to step S225. If the user does not perform the selection operation, the determination is not satisfied (step S220: NO), and this flow is terminated.

  In step S225, the CPU 45 outputs a control signal to the monitors 14 and 15 to display "Please play the K string". Incidentally, at the beginning, by the process of step S210, K = 1 and “Please play the first string” is displayed (hereinafter, the same applies to other values of K). When step S225 ends, the process proceeds to step S230.

  The user sees the display on the monitors 14 and 15 in step S225, and after removing the capostat 92, the user plays the K string (for example, 1st string) of the electric guitar 4, so that the performance signal corresponding to this plays the CPU 45. Via the internal tuner 93. In step S230, the CPU 45 determines that the pitch of the performance signal input to the internal tuner 93 is based on the result of the articulation output from the internal tuner 93 and that the reference tone of the K string performance sound (for example, A = 440 Hz, etc.). It is determined whether or not the pitch is shifted to a higher pitch (which is fixedly set in the center) (shifted to the so-called sharp side). If the performance signal of the K string is shifted to the sharp side, the determination is satisfied (step S230: YES), and the process proceeds to step S235. If the performance signal of the K string is not shifted to the sharp side, the determination is not satisfied (step S230: NO), and the process proceeds to step S240 described later.

  In step S235, the CPU 45 outputs a control signal to the monitors 14 and 15 to display that the tuning state of the open string of the K string is shifted in the higher direction (for example, sharp display by the symbol “#”). Thereafter, the process returns to step S225, and the same procedure is repeated.

  On the other hand, in step S240, the CPU 45 shifts the pitch of the performance signal input to the internal tuner 93 to a pitch lower than the reference tone of the K string performance sound based on the result of the articulation output from the internal tuner 93 (so-called so-called pitch). It is determined whether or not it is shifted to the flat side. If the performance signal of the K string is shifted to the flat side, the determination is satisfied (step S240: YES), and the process proceeds to step S245. If the performance signal of the K string is not shifted to the flat side, the determination is not satisfied (step S240: NO), and the process proceeds to step S250 described later.

  In step S245, the CPU 45 outputs a control signal to the monitors 14 and 15 to display that the tuning state of the open string of the K string is shifted in the lower direction (for example, a flat display of the symbol “♭”). Thereafter, the process returns to step S225, and the same procedure is repeated.

  In step S250, the CPU 45 responds to the fact that the determinations in steps S230 and S240 are not satisfied (that is, no deviation occurs in the tuning state of the open string of the K string). A control signal is output, and tuning OK display indicating tuning completion (no pitch shift) is performed. Thereafter, the process proceeds to step S255.

  In step S255, after adding 1 to K, the CPU 45 proceeds to step S260.

  In step S260, the CPU 45 determines whether or not K has reached the maximum number of strings of the guitar instrument (6 in this example). If K has not reached 6 (K <6), the determination is not satisfied (step S250: NO), and the process returns to step S225 to repeat the same procedure. When K reaches 6 (K = 6), the determination is satisfied (step S260: YES), and the process proceeds to step S265.

  In step S265, the CPU 45 outputs a control signal to the monitors 14 and 15, and displays "Tuning completed" indicating that tuning of all the strings of the electric guitar 4 has been completed. Thereafter, the process proceeds to step S135 in FIG.

  Note that, as described above, the internal tuner 93 determines the performance signal of each open string of the guitar and the reference of a predetermined K string (K = 1 to 6 or the like) when the tuning is performed. Although contrast with sound was performed, it is not restricted to this. That is, the internal tuner 93 may perform the above comparison in a state where the capotast 92 is still attached to the neck 90. In this case, when the operator inputs the position of the capotast 92 to the internal tuner 93 by an appropriate operation, the internal tuner 93 shifts the corrected reference sound shifted according to the position of the capotast 92 with respect to the reference sound. And the performance signal may be compared. Alternatively, the internal tuner 93 may select each pitch (for example, 12 pitches of C, C #, D, D #, E, F, F #, G, G #, A, A #, B, or partially from them) Each of the absolute pitch signals) may be stored, and the performance signal with the capostat 92 attached may be close to and match one of the absolute pitch signals. “Sharp” and “flat” may be displayed. In this case, the guitar can be tuned without performing the operation input of the position of the capostat 92 by the operator as described above.

  As described above, in the karaoke apparatus 10 according to the present embodiment, when a reservation for a karaoke piece by a user is accepted, a guitar instrument performance part (in this example, an electric guitar performance part) is included in response to the reservation. Karaoke song data is played. At that time, the capostat position data of the guitar instrument performance part is associated with the karaoke music data in advance, and the capostat position data is displayed by the monitors 14 and 15 when the karaoke music data is reproduced.

  In the present embodiment, when there are a plurality of reserved songs for karaoke music including the guitar performance part as described above (including the case where the total number of reserved songs is increased to a plurality of songs as described above). Determines the playback order of a plurality of karaoke song data by the processing of each procedure of steps S10 to S105 in the flow of FIG. 11 so that the user's labor burden can be reduced (as described above, once determined). Including rearranged playback order). That is, the order is determined so that the capotast position data of the two adjacent karaoke piece data in the adjacent order are the same (the difference is 0) or the difference is minimized (FIG. 11 step S35, step S40, step S55, step S60, step S80, step S85, and step S90). As a result, the plurality of karaoke pieces are arranged in such an order that the position of the capostat 92 is not changed or the moving distance is minimized when one piece ends and moves to the next piece. For example, in the example of FIGS. 12A to 12H described above, the value of the difference between the capostat positions of adjacent songs in the adjacent order is “0” (a part of the capostat 92 except for a part of FIG. 12H). No change in position) or “1” (the position of the capostat 92 need only be shifted by one fret). In this way, in the present embodiment, it is possible to reduce the labor burden of changing the mounting position of the capostat 92 performed by the user between the songs at the time of playing a plurality of karaoke songs, improving the convenience for the user can do.

  In the present embodiment, in particular, the order of the songs currently being played or being prepared for playback is left as it is, and the reservation of a plurality of karaoke song data thereafter is a karaoke song having the same capotast position as described above. The playback order is determined so that the data is continuously played back, or the difference between adjacent karaoke song data is as small as possible. As a result, at least a plurality of karaoke pieces at the same specific capo tast position are continuously reproduced. As a result, while the plurality of karaoke pieces are continuously reproduced, the work for changing the mounting position of the capostat 92 is not necessary, and the convenience of the user can be improved without fail.

  As in the above embodiment, when determining the playback order of a plurality of subsequent karaoke song data while keeping the order of the songs currently being played or being prepared for playback, the songs currently being played or being prepared for playback are determined. For the karaoke music data to be played in the next order, the play order is determined so that the difference from the capotast position is as small as possible, taking into account the capotast position of the song currently being played or prepared for playback. You may make it perform. That is, when there is karaoke song data that is already being played when a reservation for a plurality of karaoke songs is received, a plurality of karaoke songs corresponding to the karaoke song data being played and the received karaoke songs The reproduction order of the plurality of karaoke song data is set so that the difference between the capotast position data in the two adjacent karaoke song data in the karaoke song data group combined with the song data is 0 or minimized. It is determined. In this case, in step S10 and step S15 of FIG. 11, after the key information is captured and the capo last position is calculated including the music currently being reproduced or currently being prepared for reproduction, the current reproduction or the current reproduction is being prepared. It is sufficient to forcibly set the order of the songs to the first and determine the order of the second and subsequent playback orders using the same procedure as in steps S20 to S105 for the remaining reserved songs.

  As a result, when determining the playback order of the karaoke song data, not only the capotast position of each of the reserved karaoke songs but also the current capotast position corresponding to the currently played karaoke song is taken into account. It is possible to reduce the labor burden in changing the mounting position of 92. This result can further improve the convenience for the user.

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

  Further, the flowcharts shown in FIGS. 11, 13, and 14 do not limit the present invention to the procedures shown in the above-described flow, and the addition / deletion of the procedures or the order of the procedures are within the scope not departing from the gist and technical idea of the invention. Changes may be made.

  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.
