<Features of this embodiment>
In the above basic configuration, the feature of this embodiment is that when the performer is playing the electric guitar 4 in the minus one playback state excluding the electric guitar playing part, the player performs the performance in the minus one playback state at the player's own will. Is to be able to cancel. That is, when using a karaoke music reproduction service, a plurality of persons usually enjoy the same room together. When an electric guitar player performs his / her electric guitar 4 in the minus one playback state as described above, if the player performs well, it is comfortable for the roommate and high entertainment can be obtained with a live feeling. If the performance is poor, it will be painful for the roommates. Accordingly, the karaoke device 10 is provided with a musical instrument performance scoring function, and when the scoring value of the performance of the electric guitar 4 is low, a display prompting to cancel the minus one playback state is performed. The details will be described below with reference to FIG.

  FIG. 9 shows the processing contents executed by the CPU 45 when the karaoke apparatus 10 plays the music. In FIG. 9, this flow starts 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. 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 startup 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. 9, first, in step S10, the CPU 45 initializes a flag F relating to the reproduction state of the karaoke song data to F = 0. Note that F = 0 indicates that karaoke music data including a plurality of instrument performance parts is reproduced in a minus one playback state excluding the electric guitar performance part, and F = 1 indicates that all karaoke music data is reproduced. It shows that the playback is performed in the normal playback state including the performance part.

Thereafter, in step S15, the CPU 45 reads the instrument type detected by the detection ports PO0 to PO3 from the input ports D0 to D7 via the expansion I / O port 88 as designated data. Thereafter, the process proceeds to step S20.
(Please delete Figure 11)

  In step S20, the CPU 45 retrieves designated data from the data table 78 stored in the ROM 47 based on the data read in step S15. 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 S20 ends, the process proceeds to step S25.

  In step S25, the CPU 45 temporarily stores in the RAM 46 the designated data retrieved in step S20 (in this example, designated data X8H). Thereafter, the process proceeds to step S30.

  In step S30, 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. Until the music selection is completed, the determination is not satisfied (step S30: NO), and a loop is waited. When the music selection is completed, the determination is satisfied (step S30: YES), and the process proceeds to step S35.

  In step S35, the CPU 45 temporarily stores the music selection number data indicating the music selection number in the RAM 46 corresponding to the music selection result in step S30, and transmits the music data 100 corresponding to the music selection 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 music data 100 corresponding to the music selection number indicated in the request signal from a storage device (not shown), and the read music data 100 is transmitted to the control device via the LAN line 15. 20 to send. When step S35 is completed, the process proceeds to step S40.

  In step S <b> 40, the CPU 45 receives the song data 100 transmitted from the server 58 via the LAN line 15 via the LAN board 50. Thereafter, the process proceeds to step S45.

  In step S45, the CPU 45 temporarily stores the song data 100 received in step S40 in the RAM 49. Thereafter, the process proceeds to step S50.

  In step S50, the CPU 45 reads the designation data (designation data X8H in the above example) stored in the RAM 46 in step S45. Thereafter, the process proceeds to step S55.

  In step S55, the CPU 45 starts reading the MIDI data 110 stored in the RAM 49 in step S45 described above. Thereafter, the process proceeds to step S60.

  In step S60, the CPU 45, based on the designation data read in step S50 (in this example, designation data X8H), the MIDI data read out in step S55 and to be processed at this time is specified by the MIDI data designated in 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 S60: YES), and the process proceeds to step S65. If it is not the specified MIDI data, the determination is not satisfied (step S60: NO), and the process proceeds to step S75 described later.

  In step S65, the CPU 45 determines whether or not the flag F relating to minus one reproduction is F = 1. When F = 0, the determination in step S65 is not satisfied (step S65: NO), and the process proceeds to step S70. If F = 1, the determination at step S65 is satisfied, and the routine goes to step S75 described later.

  In step S70, the CPU 45 deletes the MIDI data to be processed at this time. Thus, when steps S55 to S140 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 out in step S50, the MIDI data # 4. 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 S70 is completed, the process proceeds to step S75.

  In step S75, the CPU 45 sends the MIDI data 110, which has been read in step S55 and then processed in steps S60 to S70, to the MIDI tone generator board 51 according to the count of a timer built in the CPU 45 via a sequencer (not shown). Write to. If the MIDI data is deleted in step S70 (because there is no write target), this procedure is substantially omitted. When step S75 is completed, the process proceeds to step S80.

  In step S80, 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 S75. 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 S80 ends, the process proceeds to step S85.

  In step S85, the CPU 45 performs the performance of the electric guitar 4 by the performer based on the guitar performance signal (guitar sound) output from the electric guitar 4 by the performance of the performer and input to the instrument connection board 8 by the phone plug 4a. Score by a known method. This scoring is performed for each predetermined time segment. Thereafter, the process proceeds to step S90.

  In step S90, the CPU 45 determines whether or not the flag F is F = 0. If F = 0, the determination is satisfied (step S90: YES), and the routine goes to step S95. In the case of F = 1, the determination is not satisfied (step S90: NO), and the process proceeds to step S115 described later.

  In step S95, the CPU 45 determines whether or not the score value of the performance of the electric guitar 4 performed in step S85 is a score lower than a predetermined first threshold value. If the scoring value is lower than the first threshold value, the determination is satisfied (step S95: YES), and the process proceeds to step S100. On the other hand, for example, when the player's performance is relatively good and the scoring value is equal to or higher than the predetermined first threshold value, the determination is not satisfied (step S95: NO), and the process proceeds to step S140 described later. .

  In step S100, the CPU 45 outputs a display control signal to the monitors 13 and 14, and causes the player of the electric guitar 4 to perform a display prompting to stop the reproduction of the karaoke music piece in the minus one reproduction state. Thereafter, the process proceeds to step S105.

  In step S105, the CPU 45 performs a performance signal input by the phone plug 4a of the electric guitar 4 in a predetermined period after the display for urging to stop the minus one playback state is executed on the monitors 13 and 14 in step S100. Whether the input level is lower than a predetermined second threshold value. If the input level of the performance signal is lower than the second threshold value, the determination is satisfied (step S105: YES), and the process proceeds to step S110. If the input level of the performance signal is equal to or higher than the second threshold value, the determination is not satisfied (step S105: NO), and the process proceeds to step S140 described later.

  In step S110, the CPU 45 sets the flag F to 1. That is, the setting is switched from reproduction in the minus one reproduction state to reproduction in the normal reproduction state. Thereafter, the process proceeds to step S140.

  On the other hand, in step S115, the CPU 45 determines whether or not the scoring value of the performance of the electric guitar 4 performed in step S85 is higher than the first threshold value. If the scoring value is higher than the first threshold value, the determination in step S115 is satisfied (step S115: YES), and the process proceeds to step S120. On the other hand, if the scoring value is equal to or less than the predetermined first threshold value, the determination in step S115 is not satisfied (step S115: NO), and the process proceeds to step S140 described later.

  In step S120, the CPU 45 outputs a display control signal to the monitors 13 and 14 to cause the player of the electric guitar 4 to perform a display prompting the player to play the karaoke music piece in the minus one playback state. Thereafter, the process proceeds to step S125.

  In step S125, the CPU 45 plays the performance of the electric guitar 4 by the performer for a predetermined period after the display for prompting the reproduction in the minus one reproduction state is executed on the monitors 13 and 14 in step S120. Based on the guitar performance signal (guitar sound) input to the musical instrument connection board 8 by 4a, a score is given by a known method. Thereafter, the process proceeds to step S130.

  In step S130, the CPU 45 scores the score of the performance of the electric guitar 4 in step S120 above a predetermined third threshold value (may be the same value as the first threshold value or another value). It is determined whether or not. If the scoring value is greater than or equal to the third threshold value, the determination is satisfied (step S130: YES), and the routine goes to step S135. On the other hand, if the scoring value is less than the third threshold value, the determination in step S130 is not satisfied (step S130: NO), and the process proceeds to step S140 described later.

  In step S135, the CPU 45 sets the flag F to 0. In other words, the setting is switched from playback in the normal playback state to playback in the minus one playback state. Thereafter, the process proceeds to step S140.

  In step S140, the CPU 45 determines whether or not the reproduction of the song data 100 has been completed (in other words, whether or not the reading of the MIDI data in step S55 has been completed up to the last MIDI data of the song data 100). Until the reproduction of the music data 100 is completed, the determination is not satisfied (step S140: NO), the process returns to step S50 and the same procedure is repeated.

  As described above, when step S50 to step S140 are repeated, if F = 0, the MIDI data is deleted (or muted) in step S70, and playback in the minus one playback state is performed in step S80. In step S85, scoring is performed. At this time, for example, if the player's performance is relatively good, the process proceeds to step S140 through step S95, and the procedure from step S50 is repeated again, and the minus one reproduction state is continued. For example, if the player's performance is not very good, a display prompting to stop the reproduction in the minus one state is performed in step S100 through step S95.

  At this time, if the performer continues to perform without following this display, the process proceeds from step S105 to step S140 and the procedure from step S50 is repeated again, and the performance that is not very good in the minus one playback state is continued. As a result, the display prompting to stop the reproduction in the minus one state is continuously (repeated). On the other hand, if the performer stops playing the electric guitar 4 or plays the electric guitar 4 with a small sound in accordance with the above display in consideration of the roommate, F = 1 in step S110 after step S105, When the procedure from step S140 is repeated again from step S140, it is switched to the normal reproduction state instead of the minus one reproduction state.

  When switching to the normal reproduction state in this way, the reproduction in the normal reproduction state is performed in step S80 through step S50, step S55, step S60, step S65, and step S75, and scoring is performed again in step S85. Here, as described above, the player is in a normal playback state because the player's performance is not so good, but the performance is relatively good due to the music (or performance part) that the player is good at. If so, a display prompting the reproduction of the minus one state is performed in step S120 through steps S90 and S115.

  At this time, if the performer decides to switch to the minus one state in consideration of the room attendant in accordance with the display, the determination is made at step S130 via step S125 by continuing the relatively good performance as it is. Is satisfied, and F = 0 in step S135, and when the procedure from step S140 is repeated again, the normal playback state is switched to the minus one playback state. On the other hand, if it is not intended to switch to the minus one state despite the above display, if the performance of the electric guitar 4 is stopped or the electric guitar 4 is played with a small sound, the scoring result in step S125 is poor. Thus, the process proceeds from step S130 to step S140, the procedure from step S50 is repeated again, and the reproduction in the normal state is continued.

  As described above, depending on whether the player's performance is good or bad and whether or not to switch the playback state according to the recommendation by the display at that time, the procedure flow is appropriately determined. While being switched, steps S50 to S140 are repeated. When the reproduction of the song data 100 is completed, the determination in step S140 is satisfied (step S140: YES), and this flow is completed.

  In the above flow, the procedures of step S60, step S65, and step S70 function as minus one switching means described in each claim, the procedure of step S80 functions as karaoke music piece reproducing means, and step S85. The procedure of step S125 functions as a musical instrument performance scoring means. Further, the procedure of Step S90, Step S95, Step S100, Step S105, Step S110, Step S115, Step S120, Step S130, and Step S135 constitutes a minus one control means. Steps S15 and S20 function as instrument identification means.

  As described above, the karaoke apparatus 10 according to the present embodiment has a function of reproducing karaoke music data in a minus one reproduction state, and in the above example, reproduces in a minus one reproduction state excluding the performance part of the electric guitar. Can do. Thereby, the performer (user) who plays the electric guitar 4 performs the removed electric guitar performance part on the electric guitar 4 in accordance with the karaoke music reproduced in the minus one reproduction state. The user can practice the electric guitar 4 and enjoy an ensemble of the entire karaoke music.

  The karaoke apparatus 10 has a musical instrument performance scoring function. When a performance signal from the performer's electric guitar 4 is input, the performance of the electric guitar is scored. If the scoring value is lower than the first threshold value, a display prompting to stop the reproduction in the minus one reproduction state is performed on the monitors 13 and 14 (see step S100 in FIG. 9). Thus, the performer can recognize the possibility that the performance of his / her electric guitar 4 may be painful to the roommate.

  In this embodiment, the level of the performance signal in a predetermined period after the display for prompting the stop is executed in preparation for the case where the performer stops the performance of the electric guitar 4 by the recognition. If lower, the setting is automatically switched from playback in the minus one playback state to playback in the normal playback state (see step S110). Thus, as described above, the performer of the electric guitar 4 can perform the performance of the electric guitar 4 in the minus one playback state by his / her own intention, for example, by stopping the performance of the electric guitar 4 or hardly performing the performance. You can stop and take care of the roommates.

  As described above, in the present embodiment, it is possible to determine whether or not to cancel the minus one performance by the performer's own intention while inviting the performer of the electric guitar 4 to consider the roommate. it can. Therefore, the convenience of both the performer and the roommate can be improved.

  On the other hand, as described above, if the performer of the electric guitar 4 is good, the performance is comfortable for the roommate, and high entertainment can be obtained with a live feeling. Therefore, it is preferable to continue the performance as much as possible. Therefore, particularly in the present embodiment, when the performer plays the electric guitar 4 so that the musical sound overlaps with the performance part of the electric guitar 4 reproduced in the normal reproduction state, the performance of the electric guitar 4 is performed. When the scoring value is higher than the second threshold value, a display prompting the reproduction in the minus one reproduction state is performed on the monitors 13 and 14 (see step S120). Accordingly, it is possible to give a recognition to the performer that in order to please the roommate by playing his / her electric guitar 4, it may be better to use the minus one playback state.

  Then, in preparation for the case where the performer switches to the minus one playback state by the recognition, in this embodiment, the level of the performance signal in a predetermined period after the display for prompting the playback in the minus one playback state is executed. If it is greater than or equal to the third threshold value, the setting is automatically switched from playback in the normal playback state to playback in the minus one playback state (see step S135). Thus, as described above, the performer, for example, continues to play the electric guitar 4 that is good, and switches to playback in the minus one playback state by his / her own intention, and further care for the roommates is performed. can do.

  In the present embodiment, in particular, the musical instrument player's musical instrument (electric guitar 4 in this example) is connected by the processing in steps S15 and S20 in FIG. In the example, an electric guitar 4) is detected, and this switches the setting to playback in minus one playback state, excluding the performance part of the detected instrument (in this example, electric guitar 4) among a plurality of instrument performance parts. It is done.

  As a result, as described above, the player simply connects his / her own electric guitar 4 in order to start playing the electric guitar 4, and the playback setting of the karaoke music data is minus minus the performance part of the electric guitar. The mode is automatically switched to the one playback state (see step S60 and step S70 in FIG. 9). Therefore, the electric guitar player does not need to manually perform the setting for switching to the minus one playback state, and the operation labor can be reduced.

  Note that, as described above, the present invention is not limited to automatically detecting a minus one target instrument (electric guitar 4 in the above example) by connecting to the instrument connection board 8. That is, the instrument may be set manually by the remote controller 60.

  In the above description, the electric guitar 4 has been described as an example of the musical instrument in which the performance part is deleted or muted in the minus one playback state in the musical sound performance device of the present invention, but the present invention is not limited to this. Other instruments such as electric drums, keyboards and electric bass guitars are also possible.

  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.

  In addition, the flowchart shown in FIG. 9 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.
