[Karaoke device 100 side processing]
Next, the karaoke side process executed on the karaoke apparatus 100 side will be specifically described with reference to the flowchart of FIG. The program of the karaoke device side processing is recorded in the ROM in the control unit 111 and the control unit 121 and is executed by the CPU in the control unit 111 and the CPU in the control unit 121.

  First, in S101, the control unit 111 receives an operation from the user. The operation from the user includes an instruction whether to perform accompaniment using musical instrument sound data of karaoke music, input of a musical instrument to be played, and input of music to be played. At this time, a screen for prompting an operation is displayed on the display unit 112. In step S101, the control unit 111 acquires information on which musical piece the user plays with which musical instrument and whether or not the accompaniment of the musical instrument sound data of the karaoke musical piece is used.

  In S102, the control unit 111 transmits information regarding the operation received in S101 to the server 200 as an inquiry signal. However, the musical composition code of the musical piece to be played is transmitted as an inquiry signal only when it is instructed not to perform accompaniment using the musical instrument sound data of the karaoke musical piece in S101 and the musical instrument to be played is other than a percussion instrument. It is assumed that the response signal from the server 200 in response to the inquiry signal transmitted from the remote controller 110 is received before the process of S109 described later is executed.

  In S103, the control unit 111 determines whether or not it is instructed to perform accompaniment using instrument sound data of karaoke music in S101. Here, the karaoke music is music data of normal communication karaoke, and music information necessary for ensemble by a user represented by guide melody, percussion instrument sound information, etc. is incorporated in advance in the karaoke music. The conventional music data is in the MIDI format. However, some recent karaoke music records PCM-recorded percussion instrument sounds (live sounds) together with information for identifying percussion instruments (instrument codes). In this process, when it is determined that an accompaniment is instructed using instrument sound data of karaoke music (S103: YES), the control unit 111 transmits the music code of the music to be played to the remote controller 110 for processing. To S104.

  In S <b> 104, the control unit 121 of the commander 120 reproduces the musical tone of the received music code by muting other than the percussion instrument sound, and acquires instrument sound data of the played instrument via the instrument sound acquisition unit 130. . The user performs the musical instrument based on the tempo of the percussion instrument sound to be reproduced. That is, the musical instrument is played while being synchronized with the percussion instrument sound to be reproduced. As a result, since the acquired instrument sound data includes data serving as a tempo reference, it is possible to synchronize with other instrument sound data. If the musical tone data to be reproduced does not exist in the commander 120, the commander 120 requests the musical tone data from the server 200.

  In S <b> 105, the control unit 121 creates post data and transmits the created post data to the server 200. The posted data includes instrument sound data, music code, instrument code, and contributor code of the played instrument. Here, the information acquired in S101 is used again for the instrument sound data and the music data. Further, when the user is logged in to the remote controller 110, the user ID of the login can be used as a contributor code. Note that the control unit 121 may display the music code and instrument code candidates that can be input via the remote controller 110 (identifiable by the control unit 201) on the display unit 112 and allow the user to post.

On the other hand, when it is determined in S103 that it is instructed not to perform accompaniment using instrument sound data of karaoke music (S103: NO), the control unit 111 shifts the process to S106.
In step S106, the control unit 111 determines whether the musical instrument to be played input in step S101 is a percussion instrument (for example, a drum). In this process, when it is determined that the musical instrument to be played is a percussion instrument (S106: YES), the control unit 111 instructs the commander 120 to acquire musical instrument sound data, and the process proceeds to S107.

In step S <b> 107, the control unit 121 of the commander 120 acquires instrument sound data of the played instrument via the instrument sound acquisition unit 130. The user plays the percussion instrument at his favorite tempo.
In S <b> 108, the control unit 121 creates post data and transmits the created post data to the server 200. The posted data includes instrument sound data, music code, instrument code, and contributor code of the played instrument. Here, the information acquired in S101 is used again for the instrument sound data and the music data. Further, when the user is logged in to the remote controller 110, the user ID of the login can be used as a contributor code. Note that the control unit 121 may display candidates for music codes and instrument codes that can be input via the remote controller 110 (identifiable by the control unit 201) on the display unit 112 and allow the user to post.

On the other hand, when it is determined in S106 that the musical instrument to be played is not a percussion instrument (S106: NO), the control unit 111 shifts the process to S109.
In step S <b> 109, the control unit 111 determines whether or not the instrument sound data of the percussion instrument of the music to be played has been posted in the posted music database 302. The answer signal received from the server 200 is used for this determination. In this process, if it is determined that the percussion instrument sound data has been posted (S109: YES), the process proceeds to S110.

  In S110, the control unit 111 determines whether or not there are a plurality of posted instrumental sound data. In this process, when it is determined that there are a plurality of posted instrumental sound data (S110: YES), the control unit 111 shifts the process to S111.

  In S <b> 111, the control unit 111 accepts an operation regarding which musical instrument sound data is to be played back among musical sound data of a plurality of percussion instruments. At this time, the control unit 111 displays an explanation of each instrument sound data on the display unit 112 (“poster code (corresponding to user ID)”, “post date / time”, “instrument code (instrument code) of the user who created the instrument sound data” Or the like. ”In addition, each instrument sound data may be used to view the musical sound.In this case, each instrument sound data is included in the answer signal for viewing. Configure as follows.

In S112, the control unit 111 instructs the commander 120 to reproduce the musical sound of the percussion instrument sound data, and shifts the processing to S113.
In step S <b> 113, the control unit 121 of the commander 120 reproduces a musical sound using the instructed percussion instrument sound data, and acquires instrumental sound data of the played instrument via the instrument sound acquisition unit 130. The user performs the musical instrument based on the musical tone tempo of the percussion instrument sound data. That is, the musical instrument is played while being synchronized with the percussion instrument sound to be reproduced. As a result, since the acquired instrument sound data includes data serving as a tempo reference, it can be synchronized with other instrument sound data.

  In S <b> 114, the control unit 121 creates post data and transmits the created post data to the server 200. The posted data includes instrument sound data, music code, instrument code, and contributor code of the played instrument. Here, the information acquired in S101 is used again for the instrument sound data and the music data. Further, when the user is logged in to the remote controller 110, the user ID of the login can be used as a contributor code. Note that the control unit 121 may display candidates for music codes and instrument codes that can be input via the remote controller 110 (identifiable by the control unit 201) on the display unit 112 and allow the user to post.

On the other hand, when it is determined in S109 that the instrument sound data of the percussion instrument has not been posted (S109: NO), the control unit 111 shifts the process to S115.
In S115, the control unit 111 displays on the display unit 112 that the instrument sound data cannot be posted. Further, it may be displayed on a display connected to the commander 120.
As a result, the control unit 111 prohibits posting of the instrument sound data when played by the instrument selected in S101. Note that the control unit 111 may be configured to prohibit the performance by the musical instrument selected in S101, or may be configured to permit the performance itself and prohibit only posting.

  According to the karaoke side processing described above, posting of musical instrument sound data that cannot be synchronized when reproducing musical sounds using a plurality of distributed musical instrument sound data is prohibited. Only posted instrument sound data that can be easily synchronized with other data is recorded, and as a result, each instrument sound data can be reliably synchronized in the playback apparatus.
