[User Usage 3]
The user usage mode 3 is a mode in which there is one logged-in user and one or more musical instruments are connected, and the performance information of the user is stored in the performance information storage area 113. The flow of processing in user usage mode 3 will be described with reference to FIG. The flowchart of FIG. 2 is started by selecting a musical instrument performance mode. The description of processing common to user usage mode 1 and user usage mode 2 is omitted.

  If it is determined in step S140 that the performance information is stored, the process proceeds to step S150.

  In step S150, it is determined whether or not performance information including instrument identification information of an instrument different from the instrument to be played is stored. For example, since each channel is configured as a dedicated channel according to the connected instrument, the instrument identification information is determined by the channel from which the performance sound of the instrument is input, and the determined instrument type is the instrument It is stored together with performance information as identification information. Further, before playing the instrument, the user operates the instrument to determine the channel and the type of instrument corresponding to the channel. The determination in step S150 is executed based on whether or not the instrument identification information stored in the performance information matches the instrument identification information corresponding to the instrument type determined by the user's instrument operation. As a result of determining whether or not they are different, if it is determined that the instrument type is different, the process of step S150 is YES, and the process proceeds to step S160. If it is determined that the instrument types match, the process of step S150 is NO, and the process proceeds to step S111.

  In step S160, it is determined whether or not the login user setting stored in the login information storage area 115 in association with the user ID is set to a storage / reproduction state indicating that performance information is stored and reproduced. . Since this process is the same as the process in step S143 described above, description thereof is omitted. If it is determined in step S160 that the login user setting in the storage / playback state is stored in the login information storage area 115, the process in step S160 is YES, and the process proceeds to step S170. If it is determined that the login user setting in the storage / playback state is not stored in the login information storage area 115, the process of step S160 is NO, and the process proceeds to step S111.

  Step S170 is a subroutine of performance information and accompaniment information reproduction subroutine. The performance information and accompaniment information are read and reproduced in synchronization. When the accompaniment information and performance information of the music reserved by the process of step S147 are reproduced, reading of accompaniment information in step S172 described later and reading of performance information in step S174 are not executed.

(Processing of playback information and accompaniment information playback subroutine)
The processing of the performance information and accompaniment information reproduction subroutine in step S170 will be described with reference to FIG. The flowchart of FIG. 3 shows the processing of the performance information and accompaniment information reproduction subroutine. The process of each step of the subroutine of the performance information and accompaniment information reproduction is a process executed by the control unit 100.

  In step S171, it is determined whether or not the accompaniment information of the reserved music is already stored in the RAM 102. Specifically, it is determined whether or not accompaniment information including music identification information that matches the music identification information of the reserved music is already stored in the RAM 102. Accordingly, when it is determined that accompaniment information including music identification information that matches the music identification information of the reserved music is stored, the process of step S171 becomes YES, and the process proceeds to step S173. If it is determined that accompaniment information including music identification information that matches the music identification information of the reserved music is not stored, the process of step S171 is NO, and the process proceeds to step S172. Since the process of step S172 is the same as the process of step S111 and step S141, the description thereof is omitted.

  In step S173, it is determined whether or not performance information corresponding to the reserved music is already stored in the RAM 102. Specifically, it is determined whether or not the music identification information of the reserved music and the performance information including the user ID of the user are already stored in the RAM 102. When it is determined that the music identification information of the reserved music and the performance information including the user ID of the user are stored, the process of step S173 is YES, and the process proceeds to step S175. When it is determined that the music identification information of the music reserved by the user and the performance information including the user ID of the user are not stored, the process of step S173 is NO, and the process proceeds to step S174.

  In step S174, performance information is read from the performance information storage area 113. Specifically, music identification information and performance information that matches the user ID of the user are read from the performance information storage area 113. The read performance information is stored in the RAM 102. When the performance information is stored in the RAM 102, the process of step S174 is moved to step S175.

  In step S175, the performance information and accompaniment information stored in the RAM 102 are reproduced in synchronization. Specifically, performance information and accompaniment information are sent from the RAM 102 to the sound control unit 140. At the same time that the performance information and accompaniment information are sent, information about the performance start time is sent to the audio control unit 140, and the performance information and accompaniment information are reproduced in synchronization.

  In step S176, it is determined whether or not the reproduction of performance information and accompaniment information has been completed. Specifically, if it is determined that the accompaniment information has been reproduced, the process of step S176 is YES, the subroutine process is terminated, and the process proceeds to step S146. If it is determined that the accompaniment information has not been reproduced, the process of step S176 is NO, and the process proceeds to step S171. The processing from step S171 to step S176 is repeated until the reproduction of the accompaniment information and the performance information is completed.

  Since the process after step S146 is the same as the usage pattern 2 of the user, the description thereof is omitted.

[Effect of the embodiment]
In the present embodiment, preparation processing for one user to practice playing a musical instrument is quickly and easily performed by steps such as step S140, step S143, step S150, and step S160.

  User usage mode 1 is a mode in which there are a plurality of login users. In this user usage mode 1, a normal music reproduction operation is performed so that all users in the karaoke room can enjoy playing musical instruments together or having a session together.

  The user usage mode 2 is a mode in which there is one logged-in user and one or more musical instruments are connected, and the performance information of the user is not stored in the performance information storage area 113. In this user usage mode 2, since performance information is not stored, it is not possible to perform a session with the performance sound of the musical instrument played first. However, performance information is stored in order to be able to session with the performance of another musical instrument that he or she will perform next time. Even if the user does not make a setting for recording the performance sound of the musical instrument, the control unit 100 determines whether or not the user intends to have a session in step S143, and the performance information is obtained in step S144. It is stored in the storage area 113. This prevents performance information from being stored due to forgotten operation.

  The user usage mode 3 is a mode in which there is one logged-in user and one or more musical instruments are connected, and the performance information of the user is stored in the performance information storage area 113. In this user usage mode 3, in step S170, the user's trouble of selecting performance information can be saved, and further, replaying of performance due to forgetting to select performance information can be prevented.

[Modification]
[Modification 1]
In step S150 of the present embodiment, it may be determined whether or not performance information including a performance part representing a melody corresponding to a type of musical instrument different from the musical instrument to be played is stored. At the time of music reservation, the user operates the operation unit 151, the portable terminal, or the remote controller to select a performance part corresponding to the type of musical instrument. The determination in step S150 is executed based on whether or not the performance part selected by the user is different from the performance part corresponding to the music identification information of the performance information stored in the performance information storage area 113.

[Modification 2]
In the user usage mode 3 of the present embodiment, the performance information may be stored in the performance information storage area 113. When the performance information is stored in the performance information storage area 113, the processing of step S143 and step S144 may be executed after step S175.

[Modification 3]
In the present embodiment, the performance information is information representing the performance sound of the musical instrument by the user, but may include an image representing the performance state of the user's musical instrument. Specifically, when the performance information includes a video, in step S173, the control unit 100 sends the video stored in the performance information to the video RAM 120 for storage. In step S175, the video stored in the video RAM 120 is sent the performance start time information to the audio control unit 140, and at the same time, the video playback unit 121 is also sent the performance start time information, according to the performance information and accompaniment information. The performance sound and the accompaniment sound are reproduced, and the video included in the performance information is reproduced synchronously. In order to include video in the performance information, the music reproducing device 1 may include a camera (not shown) and store the video from the camera in the performance information.

[Modification 4]
In the present embodiment, when the performance information and the accompaniment information are played back synchronously, the same performance part as the performance part included in the performance information may be minus one from the accompaniment information. Further, the performance part of the musical instrument played by the user may be minus one from the accompaniment information. When the music reproducing apparatus 1 according to the present embodiment executes minus one, the performance information stores information on the played instrument part, and the instrument performance part of the accompaniment information corresponding to the performance part of the instrument is minus. It only has to be done. For example, when the accompaniment information is MIDI data, the musical instrument performance part corresponding to the musical instrument performance part stored in the performance information in step S142 or step S175 may be minus one.

[Modification 5]
In the present embodiment, the instrument connecting means has a plurality of channels, but it may be one. When there is only one channel, the user inputs information about the type of instrument when reserving a song or connecting an instrument, and the external input unit can identify the instrument even if there is only one channel You can do it.

[Modification 6]
In step S <b> 111 of the present embodiment, the control unit 100 may read background video information corresponding to the music identification information from the storage unit 110. In this case, the control unit 100 stores the read background video information in the video RAM 120. In step S112, the control unit 100 sends a playback instruction for playing back the background video information stored in the video RAM 120 in step S111 to the video playback unit 121. Similar to the accompaniment information and the lyrics telop, the video playback unit 121 plays back the background video information based on the performance start time information included in the playback instruction and sends it to the video control unit 122. The video control unit 122 combines the lyrics telop and the background video and causes the display 201 to display them. Since the video playback unit 121 plays back based on the performance start time information, the background video, the accompaniment information, and the lyrics telop can be played back in synchronization.
