<Features of this embodiment>
In the above basic configuration, the feature of the present embodiment is that the karaoke apparatus 10 determines whether the karaoke apparatus 10 is installed in the musical instrument performance room or the singing room according to the presence / absence of the connection authentication with the musical instrument box 6. In response, switching to either the musical instrument performance mode or the singing mode. Details will be described below.

<Significance of instrument box>
As described above, a store that provides a user with a karaoke music data reproduction service usually arranges the karaoke apparatus 10 in each of a plurality of rooms and provides the service for each room. When starting a service for a user who plays a musical instrument as described above, a room in which a karaoke device is provided for performing a karaoke music data reproduction service for a user who sings as usual, and a user who plays a musical instrument On the other hand, there is a possibility that a room in which the karaoke apparatus 10 according to the present embodiment capable of performing the reproduction service of karaoke music data is mixed. Alternatively, even in the room where the karaoke apparatus 10 according to the present embodiment is arranged, there is a case where the user does not have a musical instrument and uses only singing as usual.

  The manager on the store side needs to make different billing calculations for a user who sings and a user who plays a musical instrument. In addition, from the viewpoint of improving serviceability, which type of karaoke apparatus is used in each room, and even the karaoke apparatus 10 according to the present embodiment is used only for singing by the user. It is necessary to manage from time to time whether it was used for musical instrument performance.

  In this embodiment, based on the above, the karaoke apparatus 10 corresponding to a user's musical instrument performance is arranged at least in the musical instrument performance room. The musical instrument box 6 is connected to each karaoke apparatus 10 and used in order to manage the history of service provision to the user in the musical instrument performance mode. As described above, each instrument box 6 stores identification information (ID information) that is uniquely given to each instrument box 6. In providing a new service for users who play musical instruments as described above, the store side purchases a plurality of musical instrument boxes 6 in advance, for example, from a manufacturer, a karaoke distribution company, etc. (hereinafter referred to as “manufacturers etc.”) And apply for registration. Thus, the manufacturer or the like supplies the number of musical instrument boxes 6 for which application has been made to the store, and registers the identification information of each musical instrument box 6 in the server 58. On the store side, the musical instrument box 6 obtained as described above is connected to the karaoke apparatus 10 provided in the musical instrument room. With this connection, the control device 20 of each karaoke device 10 acquires the identification information of the musical instrument box 6 connected thereto from the musical instrument box 6.

  On the other hand, at this time, the karaoke apparatus 10 transmits and receives information to and from the server 58 at any given timing (described later). Based on the registration of the identification information in the server 58, the identification information of each of the plurality of instrument boxes 6 supplied from the server 58 to the store is transmitted to each karaoke apparatus 10 of the store in a list format, for example. Each karaoke apparatus 10 collates whether or not the identification information directly acquired from the instrument box 6 as described above is included in the list of identification information sent from the server 58 as described above. If the identification information acquired from the musical instrument box 6 is included in the list, the verification is OK, and the karaoke apparatus 10 shifts to a state where the musical instrument performance mode can be executed. And the karaoke apparatus 10 totals the history which provided the service to the user by the musical instrument performance mode, and reports to the server 58 regularly (as mentioned above, details are mentioned later).

<Control procedure in karaoke equipment>
The processing contents executed by the CPU 45 in the karaoke apparatus 10 are shown in FIG. In FIG. 9, 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 of the control device 20. In conjunction with the rising of the power supply of the control device 20, the power supplies of the amplifier 16, the musical instrument connection board 8 and the monitors 13 and 14 are started up. As described above, in this example, a case where the user of the karaoke apparatus 10 connects the electric guitar 4 to the musical instrument connection board 8 via the musical instrument box 6 and plays the electric guitar 4 will be described as an example. In this case, the user connects the instrument cable 96 a from the electric guitar 4 to the instrument box 6. Thereafter, the user further connects the instrument cable 96 c and the USB cable 96 b from the instrument box 6 to the instrument connection board 8. By connecting the musical instrument cable 96c to the horn 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 mode flag F so that F = 0. Thereafter, the process proceeds to step S200. In this mode flag F, F = 0 represents a state in which the karaoke apparatus 10 is used in the singing mode. F = 1 represents a state in which the karaoke apparatus 10 is used in the musical instrument performance mode (details will be described later).

  In step S <b> 200, the CPU 45 performs a musical instrument box setting process for establishing an electrical connection between the electric guitar 4 and the musical instrument connection board 8 via the musical instrument box 6.

  The instrument box setting process in step S200 will be described with reference to FIG. In FIG. 10, first, in step S <b> 210, the CPU 45 determines whether or not the mode flag F is “1”. As will be described later, when the musical instrument box 6 is connected to the musical instrument connection board 8 and the verification is OK (to be described later) by the control device 20, F = 1 and the determination is satisfied (step S210: YES). finish. If the musical instrument box 6 is not connected to the musical instrument connection board 8 or is connected, if it is collation NG (described later), F = 0 remains and the determination is not satisfied (step S210: NO), and step The process moves to S215.

  In step S215, the CPU 45 determines whether or not a new instrument box 6 has been connected. As described above, when a musical instrument box 6 is newly supplied from a manufacturer or the like, the musical instrument box 6 and the musical instrument connection board 8 are connected by the USB cable 96b and the musical instrument cable 96c. By connecting the USB cable 96b to the musical instrument connection board 8, the CPU 45 identifies that the musical instrument box 6 is connected. When the connection of the musical instrument box 6 is newly identified by the CPU 45 in this way, the determination in step S215 is satisfied (step S215: YES), and the process proceeds to step S220. If the instrument box 6 is not newly connected, the determination in step S215 is not satisfied (step S215: NO), and this routine is terminated.

  In step S220, the CPU 45 acquires the identification information of the musical instrument box 6 as mode setting information stored in the memory of the musical instrument box 6 via the USB cable 96b. And CPU45 memorize | stores the acquired identification information in RAM49, for example. Thereafter, the process proceeds to step S225.

  In step S225, the CPU 45 transmits a setting report to the server 58 via the LAN line 95 to the effect that the setting process accompanying the connection with the instrument box 6 has been completed as described above. Thereafter, the process proceeds to step S230.

  In step S230, in response to the transmission of the setting report to the server 58 in step S230, a list of instrument box identification information transmitted from the server 58 via the LAN line 95 (described later) is received. As described above, this list of identification information is created in advance for each store where the karaoke apparatus 10 is installed, and is a list in which identification information about the number of instrument boxes provided in the store is described. The list is not received when the setting report is transmitted to the server 58 as described above, but the list is received together with information transmission / reception periodically performed with the server 58. It may be. When step S230 ends, the process proceeds to step S235.

  In step S235, the CPU 45 collates the identification information of the musical instrument box 6 acquired in step S220 with the list of identification information received in step S230. Then, the CPU 45 determines whether the collation is OK, that is, whether the identification information acquired from the instrument box 6 matches any of the identification information in the list. If the verification is OK, the determination is satisfied (step S235: YES), and the process proceeds to step S240. When the determination in step S235 is satisfied, the instrument box 6 is set to the karaoke apparatus 10 as an appropriate one having the authority to provide services to the user in the instrument performance mode. If the collation is NG, that is, the identification information acquired from the instrument box 6 does not match any of the identification information in the list, the determination is not satisfied (step S235: NO), and this routine is terminated.

  In step S240, the CPU 45 changes the mode flag F to F = 1 representing a state that can be used in the musical instrument performance mode according to the result of the collation OK. Thereafter, this routine is terminated.

  Returning to FIG. 9, when step S200 is completed as described above, the process proceeds to step S20.

  In step S20, the CPU 45 determines whether or not the mode flag F is 1. As described above, if F = 1 in the collation OK, the determination in step S20 is satisfied (step S20: YES), and the process proceeds to step S25. When F = 0 other than the above-mentioned verification OK, the determination in step S20 is not satisfied (step S20: NO), and the process proceeds to step S80 described later.

  In step S25, the CPU 45 reads data from the input ports D0 to D7 by reading the chip select signal CS for selecting the expansion I / O port 88 when the predetermined read timing is reached. Thereafter, the process proceeds to step S30.

  In step S30, the CPU 45 retrieves designated data from the data table 78 stored in the ROM 47 based on the data read in step S25. For example, when the instrument box 6 to which the electric guitar 4 is connected as described above is connected, the voltage appearing at the detection port P03 changes from the low level to the high level as described above. As a result, the CPU 45 detects 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 S30 ends, the process proceeds to step S35.

  In step S35, the CPU 45 temporarily stores in the RAM 46 the designated data retrieved in step S30 (designated data X8H in the above example). Thereafter, the process proceeds to step S40.

  In step S40, the CPU 45 determines whether or not the music selection by the user has been completed. For example, when a user inputs a song selection number of a song that the user wants to sing with a numeric keypad (not shown) of the remote controller 60, a number corresponding to the numeric keypad is displayed each time the key is pressed. 23 are sequentially displayed. Subsequently, when the music selection button (not shown) is pressed after pressing the last numeric keypad, the music selection is completed. Thereby, the music selection is completed. Until the music selection is completed, the determination in step S40 is not satisfied (step S40: NO), and a loop standby is performed. When the music selection is completed, the determination in step S40 is satisfied (step S40: YES), and the process proceeds to step S45.

  In step S45, 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 S40. Further, the CPU 45 transmits a request signal for requesting transmission of the music data 100 corresponding to the music selection number to the server 58 via the LAN line 50 via the LAN line 95. As a result, the server 58 searches and reads the music data 100 corresponding to the music selection number indicated in the request signal from a storage device (not shown). Then, the server 58 transmits the read music data 100 to the control device 20 via the LAN line 95. When step S45 ends, the process proceeds to step S50.

  In step S 50, the CPU 45 receives the music data 100 transmitted from the server 58 via the LAN line 95 via the LAN board 50. Thereafter, the process proceeds to step S55.

  In step S55, the CPU 45 temporarily stores the song data 100 received in step S50 in the RAM 49. Thereafter, the process proceeds to step S60.

  In step S60, the CPU 45 reads the designated data (designated data X8H in the above example) stored in the RAM 46 in step S35 described above. Thereafter, the process proceeds to step S65.

  In step S65, the CPU 45 starts reading the MIDI data 110 stored in the RAM 49 in step S55 described above. Thereafter, the process proceeds to step S70.

  In step S70, the CPU 45 makes a determination based on the designation data read in step S60 (designation data X8H in the above example). That is, the CPU 45 reads out the MIDI sound source of the electric guitar 4 in the above example, whether or not the MIDI data read out in step S65 and processed at this time is the MIDI data designated by the designated data. It is determined whether or not the specified MIDI data # 4. If it is the specified MIDI data, the determination is satisfied (step S70: YES), and the process proceeds to step S75. If it is not the specified MIDI data, the determination is not satisfied (step S70: NO), and the process proceeds to step S105 described later.

  In step S75, the CPU 45 deletes the MIDI data to be processed at this time. Thus, when steps S65 to S110 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 S70. Is deleted (see FIG. 7B). Instead of deletion, mute data 118 for muting may be added as shown in FIG. 7C. As a result, it is possible to realize the reproduction of karaoke music data in the minus one state in which the music part of the electric guitar is substantially inaudible. When step S75 ends, the process proceeds to step S105 described later.

  On the other hand, if the determination in step S20 described above is not satisfied, the process proceeds to step S80 as described above. In step S80, the CPU 45 determines whether or not music selection by the user has been completed, as in step S40. As described above, for example, until the user operates the music selection button 69 of the remote controller 60 and the music selection is completed, the determination in step S80 is not satisfied (step S80: NO), and the loop waits. When the music selection is completed, the determination at Step S80 is satisfied (Step S80: YES), and the routine goes to Step S85.

  In step S85, the CPU 45 responds to the music selection result in step S80, and temporarily stores the music selection number data in the RAM 46 and transmits a request signal to the server 58, as in step S45. As a result, the song data 100 read from the server 58 is transmitted to the control device 20 as described above. When step S85 is completed, the process proceeds to step S90.

  In step S90, as in step S50, the CPU 45 receives the song data 100 from the server 58. Thereafter, the process proceeds to step S95.

  In step S95, as in step S55, the CPU 45 temporarily stores the song data 100 received in step S90. Thereafter, the process proceeds to step S100.

  In step S100, as in step S65, the CPU 45 starts reading the MIDI data 110 stored in step S95. Thereafter, the process proceeds to step S105.

  In step S105, the CPU 45 writes MIDI data to the MIDI tone generator board 51 via a sequencer (not shown) according to the count of a timer built in the CPU 45. The MIDI data to be written is the MIDI data 110 that has been read in step S65 and has undergone the processing in steps S70 and S75, or the MIDI data 110 that has been read in step S100.

  In step S110, 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 S105. 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 sent from the sound output terminal 41 to the amplifier 16. It is output to the mixing circuit 9. 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, if F = 1 due to the above-mentioned verification OK and the processing of steps S25 to S70 and S75 has been performed, the performance signal output from the musical instrument is the musical instrument connection board 8 and the output terminals 82d to 82d. The signal is input to the mixing circuit 9 via 85d and the like and mixed with the audio signal and the music signal. 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 the speakers 11 and 12. When step S110 ends, the process proceeds to step S115.

  In step S115, 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 S65 or step S100 has been completed up to the last MIDI data of the song data 100. judge. If the reproduction of the song data 100 is not completed, the determination is not satisfied (step S115: NO), and the process proceeds to step S120. If the reproduction of the song data 100 has been completed, the determination is satisfied (step S115: YES), and the process proceeds to step S125 described later.

  In the above description, the processes in steps S25 to S75 and steps S105 to S115 executed when F = 1 correspond to the musical instrument performance mode. Moreover, the process of step S80-step S100 and step S105-step S115 performed when F = 0 is equivalent to singing mode.

  In step S120, the CPU 45 determines whether or not the mode flag F is 1. If F = 1, the determination is satisfied (step S120: YES), the process returns to step S65, and the procedure from step S65 to step S115 in the instrument performance mode is repeated. At the time of the repetition, in the above example, the MIDI data # 4 included in the MIDI data read out in step S65 is not written to the MIDI sound source board 51, and the sound source signal indicating the sound of the electric guitar 4 is the MIDI sound source board. 51 is not output. As a result, the karaoke music data is reproduced in a minus one state where one desired musical instrument performance part, in this example, the performance part of the electric guitar 4 is removed. 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 apparatus 10 to reproduce normal karaoke music data. On the other hand, if F = 0, the determination in step S120 is not satisfied (step S120: NO), the process returns to step S100, and the procedure of steps S100 to S115 in the singing mode is repeated.

  In step S <b> 125, the CPU 45 aggregates the usage history of the karaoke apparatus 10. That is, in step S20, the operation mode is switched to the instrument performance mode or the singing mode depending on whether F = 1 or F = 0. In response to this switching, the CPU 45 divides the usage in the musical instrument performance mode and the usage in the singing mode, and performs the above-mentioned totaling for each operation mode. Thereafter, the process proceeds to step S130.

  In step S130, the CPU 45 determines whether or not it is a predetermined timing at which the usage history of the karaoke apparatus 10 counted in step S125 should be transmitted to the server. For example, the transmission timing is set to once every predetermined time of the day. If it is not the said predetermined timing, determination will not be satisfy | filled (step S130: NO), and it returns to step S200 and repeats the same procedure. If it is the said predetermined timing, determination of step S130 will be satisfy | filled (step S130: YES), and it will move to step S135.

  In step S <b> 135, the usage history of the karaoke apparatus 10 accumulated and accumulated every time step S <b> 125 is executed is transmitted to the server 58. Thereafter, this flow is terminated.

  In the above flow, the procedure of step S20 functions not only as a determination unit described in each claim but also as a switching unit. Further, the procedure of step S110 functions as a reproducing unit, and the procedure of step S125 functions as a totaling unit.

<Control procedure by server>
The control contents of the server 58 will be described with reference to FIG. FIG. 11 is a flowchart illustrating a control procedure executed by a control device (not shown) provided in server 58 when server 58 manages karaoke apparatus 10.

  In FIG. 11, first, in step S <b> 310, the control device of the server 58 determines whether or not an application for registration of the musical instrument box 6 has been made from a store where the karaoke device 10 is installed and the musical instrument box 6 is purchased. This registration application includes the name of the store where the purchased instrument box 6 is installed, the identification information of the purchased instrument box 6, and the like. If there is an application for registration of the musical instrument box 6 from the store, the determination is satisfied (step S310: YES), and the process proceeds to step S315.

  In step S315, the control device stores and registers the identification information and store name of the musical instrument box 6 acquired in step S310 in the storage device provided in the server 58. Thereafter, this flow is terminated.

  On the other hand, if there is no application for registration of the musical instrument box 6 in step S310, the determination is not satisfied (step S310: NO), and the process proceeds to step S320. In step S320, the control device determines whether or not there has been a setting report of the instrument box 6 from the store. When the setting report is transmitted from the karaoke apparatus 10 in step S225 of FIG. 10, the determination is satisfied (step S320: YES), and the process proceeds to step S325.

  In step S325, the control device gives a list of identification information of the instrument box 6 corresponding to the store where the karaoke device 10 is installed via the LAN line 95 to the karaoke device 10 for which the setting of the instrument box 6 has been reported. (Described above). Thereby, on the karaoke apparatus 10 side, as described above, it is possible to perform reception of the list of identification information of the musical instrument box in step S230 and subsequent verification. When step S325 ends, this flow ends.

  On the other hand, if the setting report is not transmitted in step S320, the determination is not satisfied (step S320: NO), and the process proceeds to step S330. In step S330, the control device determines whether or not the usage history of the karaoke device 10 has been received from the store. If the usage history of the karaoke apparatus 10 transmitted in step S135 has been received, the determination in step S330 is satisfied (step S330: YES), and the process proceeds to step S335. If the usage history has not been received, the determination is not satisfied (step S330: NO), and this flow ends.

  In step S335, the control device records the usage history of the karaoke device 10 received in step S330 in the database of the recording device provided in the server 58. Thereafter, this flow is terminated.

  As described above, the karaoke apparatus 10 according to the present embodiment includes both a musical instrument performance mode that enables musical instrument performance and a singing mode that does not support musical instrument performance, as music data playback operation modes. ing. The karaoke apparatus 10 is arranged in either a musical instrument performance room or a singing room. Then, under the control of the CPU 45, in step S20, when F = 1, the processing is switched to the instrument performance mode corresponding to the instrument performance room, and the karaoke piece data is reproduced in the instrument performance mode. On the other hand, when F = 0, the processing is switched to the processing in the singing mode corresponding to the singing room, and the karaoke music data is reproduced in the singing mode. In this manner, the usage history indicating that the karaoke apparatus 10 has been used in the musical instrument performance mode or the usage history indicating that the karaoke apparatus 10 has been used in the singing mode are totaled in step S125. . Thereby, the administrator of the karaoke device 10 can accurately acquire the usage history used by the user of the karaoke device 10 for playing the musical instrument and the usage history used for singing while distinguishing from each other. , Accurate device management can be performed.

  In the present embodiment, in particular, the musical instrument box 6 storing unique identification information indicating that it is used in the musical instrument performance room is used, and the operation mode is switched according to the collation result of the identification information of the musical instrument box 6. . As a result, the karaoke apparatus 10 depends on whether the instrument box 6 is installed or not (see step S215), and if it is installed, whether the identification information is valid (see step S235). It is possible to accurately and easily determine whether the instrument is installed in the musical instrument performance room or the singing room. That is, the CPU 45 can indirectly accurately determine that the karaoke apparatus 10 is installed in the musical instrument performance room by identifying that the mode flag F is F = 1, and the mode flag F is F = By identifying that it is 0, it can be indirectly accurately determined that the karaoke apparatus 10 is installed in the singing room. In addition, the karaoke apparatus 10 is switched to the musical instrument performance mode by installing the instrument box 6, thereby preventing the instrument performance room and the singing room from being randomly increased by setting by operating the karaoke apparatus 10. Management load can be reduced.

  In the present embodiment, in particular, when it is determined that the musical instrument performance room is used, the music data reproduction as the musical instrument performance mode is performed in the minus one state excluding a desired one musical instrument performance part among a plurality of musical instrument performance parts. Or play with the sound reduced. Thereby, the musical instrument player who is a user can enjoy a live performance feeling that combines the performance sound of the musical instrument he / she performs with the reproduction sound of the karaoke music data.

  The present invention is not limited to the above embodiment, and various modifications can be made without departing from the technical idea. Hereinafter, such modifications will be described.

(1) When the operation mode of music data reproduction is set by the remote controller 60 In the above embodiment, the karaoke apparatus 10 is connected to the instrument performance room or the musical instrument performance room based on the result of collation of the identification information of the instrument box 6 connected to the instrument connection board 8. Although it was determined in which of the singing rooms it is not limited to this. That is, the user himself / herself sets the operation mode using the remote controller 60, and uses the setting as mode setting information to determine whether the karaoke apparatus 10 is installed in the musical instrument performance room or the singing room. Also good. Hereinafter, such modifications will be described. Parts equivalent to those in the above embodiment are denoted by the same reference numerals, and description thereof is omitted or simplified as appropriate.

  FIG. 12 is an explanatory diagram showing the main configuration of the karaoke apparatus 10 in the present modification.

Other points are the same as in the above embodiment.

  FIG. 13 is a functional block diagram showing the main configuration of the control system of the control device 20 in this modification. As described above, in the control device 20 according to this modification, the electric guitar 4 is connected to the instrument connection board 8 without using the instrument box 6 described above. Other points are the same as in the above embodiment.

  In this modification, as described above, the remote controller 60 further includes a singing button and a musical instrument button for setting the operation mode. The user can set the singing mode in the karaoke device 10 by pressing a singing button, and can set the musical instrument performance mode in the karaoke device 10 by pressing a musical instrument button.

  FIG. 14 is a flowchart showing the processing contents executed by the CPU 45 in this modification. In FIG. 14, step S400 of mode setting processing is provided instead of the instrument box setting processing of step S200 of FIG.

  Details of the mode setting process in step S400 will be described with reference to FIG.

  In FIG. 15, first, in step S <b> 410, the CPU 45 determines whether or not the user has performed setting input of the operation mode using the remote controller 60. Until the user presses the singing button or the instrument button of the remote controller 60 and sets and inputs the operation mode, the determination in step S410 is not satisfied (step S410: NO), and a loop standby is performed. If the user inputs an operation mode setting, the determination in step S410 is satisfied (step S410: YES), and the process proceeds to step S415.

  In step S415, the CPU 45 determines whether or not the user has pressed the instrument button. If the user has pressed the instrument button, the determination is satisfied (step S415: YES), and the process proceeds to step S425.

  In step S425, the CPU 45 sets and stores a musical instrument performance mode as an operation mode in an appropriate mode recording area provided in the ROM 47. Thereafter, the process proceeds to step S430.

  In step S430, the CPU 45 sets the mode flag F to F = 1. Thereby, in step S25 to step S115 in FIG. 14, processing in the instrument performance mode similar to that in FIG. 9 is executed. Thereafter, this routine is terminated.

  On the other hand, if the user does not press the instrument button in step S415, the determination is not satisfied (step S415: NO), and the process proceeds to step S420.

  In step S420, the CPU 45 determines whether or not the user has pressed the singing button. If the user has not pressed the singing button, the determination is not satisfied (step S420: NO), and this routine is terminated. If the user is pressing the singing button, the determination is satisfied (step S420: YES), and the process proceeds to step S435.

  In step S435, the CPU 45 sets and stores the singing mode as the operation mode in an appropriate mode recording area provided in the ROM 47. Thereafter, this routine is terminated while F = 0. Thereby, in step S80-step S115 in FIG. 14, the process by the singing mode similar to the said FIG. 9 is performed.

  In the above flow, the entire processing in step S400 constitutes setting means described in each claim.

  In FIG. 14, the procedures other than step S400 are the same as those in FIG.

  According to this modification, as described above, the user sets the operation mode using the instrument button or the singing button of the remote controller 60. Thereby, the process of a corresponding mode can be performed according to which of the musical instrument performance mode and the singing mode is selected. Similarly to the above, the CPU 45 can indirectly and accurately determine that the karaoke apparatus 10 is installed in the musical instrument performance room by identifying that the mode flag F is F = 1. By identifying that F = 0, it can be indirectly accurately determined that the karaoke apparatus 10 is installed in the singing room.

(2) In the case where the presence / absence of activation of the musical instrument performance application is used as mode setting information In other words, in this modification, a dedicated musical instrument performance application program is executed by the CPU 45 in order to perform processing that enables musical instrument performance in the musical instrument performance mode. Used in Then, by using the presence / absence of the activation as the mode setting information, it is determined by itself whether the karaoke apparatus 10 is installed in the instrument performance room or the singing room.

  FIG. 16 is a flowchart showing the processing contents executed by the CPU 45 during music reproduction according to this modification. In the flowchart of FIG. 16, step S200, step S20, step S80, step S85, step S90, step S95, and step S120 shown in FIG. 9 are omitted. Further, step S32 and step S33 are newly provided between step S30 and step S35, and new step S57 and step S58 are provided between step S55 and step S60. The other points are the same as in FIG.

  In FIG. 16, in step S10 similar to FIG. 9, the CPU 45 initializes the mode flag F to F = 0, and proceeds to step S25.

  The procedure of step S25 and step S30 is the same as that in FIG. When step S30 ends, the process proceeds to newly provided step S32.

  In step S32, the CPU 45 determines whether there is designated data retrieved in step S30. When the electric guitar 4 is connected to the musical instrument connection board 8 directly or via the musical instrument box 6 as described above, the designation data X8H for deleting the MIDI data # 4 that designates the MIDI sound source of the electric guitar 4 exists. Will be. If there is designated data, the determination at step S32 is satisfied (step S32: YES), and the routine goes to step S33. If there is no designated data, the determination in step S32 is not satisfied (step S32: NO), and the process proceeds to step S40 described later.

  In step S33, the CPU 45 sets the mode flag F to F = 1 in response to the determination that “designated data exists” in step S32 is satisfied, that is, that the instrument is connected, and then proceeds to step S35. Move.

  The procedures of Step S35, Step S40, Step S45, Step S50, and Step S55 are the same as those in the flowchart of FIG. When step S55 ends, the process proceeds to newly provided step S57.

  In step S57, the CPU 45 determines whether or not the mode flag F is 1. If the mode flag F is F = 1 in step S33, the determination is satisfied (step S57: YES), and the process proceeds to newly provided step S58. If the mode flag F is not F = 1, the determination is not satisfied (step S57: NO), and the process proceeds to step S100 described later.

  In step S <b> 58, the CPU 45 activates a dedicated instrument performance application program (detailed explanation is omitted) for performing processing that enables performance by an instrument. That is, satisfying the determination in step S57 means starting the dedicated application in step S58. Therefore, the CPU 45 uses the presence / absence of activation of the dedicated application as the mode setting information, and indirectly identifies the activation of the dedicated application by identifying that the determination in step S57 is satisfied. It can be judged indirectly that it is installed in the musical instrument performance room. On the other hand, if the determination is not satisfied in step S57, the procedure of step S58 is not performed, and therefore the dedicated application is not activated. That is, the CPU 45 indirectly identifies that the dedicated application does not start by identifying that the determination in step S57 is not satisfied, and thereby indirectly identifies the karaoke apparatus 10 installed in the singing room. Judgment can be made. When step S58 ends, the process proceeds to step S60.

  Step S60, Step S65, Step S70, Step S75, Step S105, Step S110, Step S115 Musical Instrument Playback Procedure in Step S115 and Step S100, Step S105, Step S115 Song Playback Mode Is the same as the flowchart of FIG.

  When step S115 ends, the process proceeds to step S125. Since the procedure of step S125, step S130, and step S135 is the same as the flowchart of FIG. 9, description is abbreviate | omitted.

  In the above flow, the procedure of step S58 functions as an activation unit described in each claim. Further, the procedure of step S57 functions as a determination unit and also functions as a switching unit.

  According to this modification, the karaoke apparatus 10 is used in the musical instrument performance room according to whether or not the musical instrument performance application program that is normally activated when the musical instrument is connected is actually activated. And in the singing room can be accurately and easily determined.

  In addition, in the above, the arrow shown in each figure of FIG.3, FIG.5 etc. shows an example of the flow of a signal, and does not limit the flow direction of a signal.

  In addition, the flowcharts shown in FIGS. 9 and 14 do not limit the present invention to the procedure shown in the above-described flow, and the addition and deletion of the procedure or the change of the order within the scope of the invention and the technical idea You may do.

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