This information file is referred to by the mobile phone 200 in a file transfer process (FIG. 6) described later, and whether or not the song data file is transmitted to the electronic musical instrument 100 is controlled according to whether or not a predetermined condition is satisfied. The

  Next, each process executed by the CPU 210 of the mobile phone 200 of the present invention configured as described above will be described with reference to the flowcharts of FIGS. FIG. 5 is a flowchart of main processing in performance information transfer executed by the mobile phone 200.

  This main process is started when a performance information transfer application for performing performance information transfer is started. First, it is confirmed whether or not a request for obtaining song data is permitted (S501).

  As a result of checking in the process of S501, if the song data acquisition request is not permitted (S501: No), the electronic musical instrument 100 to which performance information is to be transferred is requested to output an information file (S502). After the process of S502, it is confirmed whether or not the information file is received within a predetermined time (for example, 10 seconds) from the output request (S503). If the information file is not received within the predetermined time (S503: No), Error processing is performed (S513), and the process returns to S502. In the error process (S513), the user is notified that the information file has not been received, and a display prompting the user to request the output again is displayed on the display 216 for a certain period of time.

  On the other hand, if the information file is received within a predetermined time as a result of the confirmation in S503 (S503: Yes), the model data is read from the received information data (S504). After the processing of S504, it is confirmed whether or not the model data read out corresponds to the corresponding model data fixedly recorded as a part of the program of the performance information transfer application stored in the flash ROM 213 ( S505).

  If the model data read out in the process of S504 is not a model corresponding to this application as a result of the confirmation in the process of S505 (S505: No), a display notifying that the model is not compatible with this application is displayed. Error processing performed for a predetermined time is performed at 216 (S514), and this performance information transfer processing is terminated.

  On the other hand, if the model data read out in S504 is a model corresponding to this application as a result of the confirmation in S505 (S505: Yes), the server 300 is requested to obtain a song data file. Permitted (S506), the process proceeds to S507.

  Through the processing of S506, the mobile phone 200 that has been permitted to obtain the song data file acquisition request to the server 300 can acquire the song data file corresponding to the model compatible with the performance information transfer application from the server 300. On the other hand, since the mobile phone 200 that cannot communicate with the electronic musical instrument of the model corresponding to the performance information transfer application is not permitted to request a song data file to the server, the song corresponding only to the model compatible with the performance information transfer application. The data file is not acquired from the server 300. Normally, when acquiring a song data file from an external server via the Internet, a fee charged for each song data file and a communication fee according to the data amount of the song data file are charged. When the user owns an electronic musical instrument of a model that does not support this application, it is convenient that there is no useless charge due to reception of a useless song data file that does not support the own model.

  On the other hand, as a result of checking in the process of S501, if the acquisition request for the song data file is permitted, the processes of S502 to S506, S513, and S514 are skipped, and the process proceeds to S507. That is, once the acquisition request of the song data file that is not permitted in the initial setting of the application is once permitted, the processing of S502 to S506, S513, and S514 is skipped from the subsequent (next) activation of the application. Processing related to transmission / reception of song data (the processing of S507 to S512 and S515 to S517 described later is executed.

  In the process of S507, it is confirmed whether or not the end of the performance information transfer application has been instructed. As a result of the confirmation in the process of S507, if the application is instructed to end (S507: Yes), the performance information transfer process is terminated.

  On the other hand, as a result of the confirmation in the process of S507, if the application termination instruction is not given (S507: No), it is confirmed whether or not an application operation instruction is given (S508). As a result of the confirmation in the process of S508, if no operation instruction is given (S508: No), the process returns to the process of S507 and waits for an application termination instruction or an operation instruction.

  As a result of the confirmation in the processing of S508, if an operation instruction has been performed (S508: Yes), what the instruction of the operation instruction is is confirmed (S509). As a result of confirmation in the process of S509, if the instruction is a reception process for receiving a song data file from the server 300 (S509: reception process), acquisition of a song data file desired to be downloaded (downloaded) to the server 300 is obtained. A request is made (S510). Next, it is confirmed whether or not the song data file has been received within a predetermined time (for example, 30 to 60 seconds) after the request for obtaining the song data file by the processing of S510 is performed (S511), and the song within the predetermined time. If a data file is not received (S511: No), an error process is performed in which a display for notifying the user that the song data file has not been received is performed on the display device 216 for a predetermined time (S516), and the process proceeds to S507. To do.

  On the other hand, if the result of the confirmation in S511 confirms that the song data file has been received within the predetermined time (S511: Yes), the song data file received in the RAM 212 is stored in the flash ROM 213 (S512). The process proceeds to S507.

  In addition, as a result of the confirmation in the process of S509, the operation instruction instructs the execution of transmission to the electronic musical instrument 100 after selecting the song data file desired to be transmitted (transferred) from the flash ROM 213 of the mobile phone 200 to the electronic musical instrument 100. If so (S509: transmission process), a file transmission process described later is executed (S515), and the process proceeds to S507.

  Furthermore, when the operation instruction is a process other than the reception process or the transmission process as a result of checking in the process of S509 (S509: other process), other processes according to the operation instruction (for example, other processes) (for example, other processes) Then, a process of deleting the song data file from the song data files already stored in the flash ROM 213 is performed (S517). After the process of S517, the process proceeds to S507.

  Next, the file transmission process (S515) will be described with reference to the flowchart of FIG. In this file transmission process (S515), first, the electronic musical instrument 100 at the file transfer destination is requested to output an information file (S601).

  After the processing of S601, it is confirmed whether or not the information file has been received within a predetermined time (for example, 10 seconds) from the information file output request (S602). If the information file is not received within a predetermined time from the output request of the information file by the process of S601 as a result of the confirmation by the process of S602 (S602: No), a display notifying the user that the information file has not been received is displayed. Error processing performed on the display device 216 is performed (S613), and the file transfer processing (S515) is terminated.

  On the other hand, if the information file is received within a predetermined time as a result of the confirmation in S602 (S602: Yes), the magic number is read from the received information file (S603). After the process of S603, it is confirmed whether or not the read magic number is a magic number that is fixedly recorded as a part of the performance information transfer application program stored in the flash ROM 213 (S604).

  If the value of the magic number read from the information file is a magic number that matches the performance processing transfer system as a result of checking in the process of S604 (S604: Yes), then model data is read from the information file ( S605). After the process of S605, it is checked whether or not the read model data corresponds to the corresponding model data that is fixedly recorded as a part of the performance information transfer application program stored in the flash ROM 213 (S606). . If the model data read from the information file is a model corresponding to this application as a result of checking in the process of S606 (S606: Yes), the free memory capacity of the electronic musical instrument 100 is read from the information file (S607). .

  After the processing of S607, the data size of the song data file is read from the header of the song data file selected for transmission (transfer) to the electronic musical instrument 100 in the operation instruction of S509 (S608). In this embodiment, the data size is read from the header of the song data file. However, the data size of the song data file may be stored in association with the song data file. The file size of each song data file stored in the flash ROM 213 of the mobile phone 200 may be displayed together with the song data file name as part of the song data list displayed on the display 216. .

  After the processing of S608, the read song data size is equal to or less than the free memory capacity read by the processing of S607 (the free memory capacity read by the processing of S607 ≧ the data size read by the processing of S608). It is confirmed whether or not (S609).

  As a result of checking in the process of S609, if the song data size read out in the process of S608 is equal to or smaller than the free memory capacity read out in the process of S607 (free memory capacity ≧ song data size) (S609: Yes). The song data file selected in the operation instruction in S509 is transmitted to the electronic musical instrument 100 (S610), and the file transfer process (S515) is terminated.

  On the other hand, as a result of checking in the process of S609, if the song data size read out in the process of S608 exceeds the free memory capacity read out in the process of S607 (free memory capacity <song data size) ( (S609: No), the electronic musical instrument 100 performs an error process for displaying on the display 216 that the user has no free memory capacity to receive the song data file selected for transmission (S611). The error file including the error number is transmitted to the electronic musical instrument 100 (S612). When the electronic musical instrument 100 receives the error file transmitted in the process of S612, the electronic musical instrument 100 executes predetermined error processing based on the received error file (see FIG. 7). After the process of S612, this file transfer process is terminated.

  If the electronic musical instrument 100 that is the transfer destination of the song data file has enough free memory capacity to store the selected song data file by the processing of S609 to S612, the song data file is transmitted. If the musical instrument 100 does not have a sufficient free memory capacity, the song data file is not transmitted. As a result, since the song data file is started to be transmitted from the mobile phone 200 to the electronic musical instrument 100, the file transmission process executed halfway is canceled due to a shortage of memory on the electronic musical instrument 100 side, and time and labor are wasted. Can be suppressed.

  If the magic number read from the information file is a magic number that does not correspond to the performance information transfer system (S604: No) as a result of the confirmation in S604, the file is not correct (this performance). An error process is performed to display on the display 216 to notify the user that the file does not match the information transfer system (S613), and the file transfer process (S515) is terminated. By the process of S604, the song data file is not transmitted to the electronic musical instrument 100 that does not have the magic number of the predetermined value, that is, does not correspond to the performance information transfer system. Therefore, it is possible to prevent the song data file from being transmitted to an unspecified number of electronic devices (electronic musical instruments, computers, etc.), thereby preventing, for example, unauthorized duplication of the song data file by the computer. it can.

  Furthermore, if the model data read from the information file is not a model that corresponds to this application as a result of checking in the process of S606 (S606: No), the electronic musical instrument 100 that is the song data transmission destination is a model that does not support the application. An error process is performed to display on the display 216 to notify the user of the presence (S613), and the file transfer process (S515) is terminated. By the processing of 606, the song data file is not transmitted to the electronic musical instrument 100 that is not compatible with the application, that is, the song data file transmitted by the application is not compatible and cannot be used. Therefore, useless transfer processing can be suppressed and useless charging can be suppressed. In addition, information regarding various errors is displayed on the display 216 by the error processing of S613 or S611, so that the user can know the cause of the error.

  Next, a file reception process executed by the CPU 110 of the electronic musical instrument 100 will be described with reference to the flowchart of FIG. This file reception process is a process that is activated when an output request for the information file output in the process of S601 of the file transfer process (FIG. 6) of the mobile phone 200 is received.

  In this file reception process, first, the value of a timer counter T (not shown) provided in the RAM 112 is set to “0” (S701). After the processing of S701, an information file (FIG. 4) including a magic number, model data, and information on the free memory capacity of the flash ROM 113 is created (S702). After the process of S702, the created information file is transmitted to the mobile phone 200 that requested the output of the information file (S703).

When information about the electronic musical instrument 100 is transmitted to the mobile phone 200 by the processing of S703, the transmission of the song data file is controlled according to the content in the file transmission processing (FIG. 6) executed by the mobile phone 200. When the electronic musical instrument 100 is not compatible with this performance information transfer system, and when the free memory capacity of the flash ROM 113 of the electronic musical instrument 100 is not sufficient to store the song data file, the electronic musical instrument 100 is transferred from the mobile phone 200 to the electronic musical instrument 100. Does not send song data files. Therefore, useless transfer processing can be omitted.

After the processing of S703, “1” is added to the timer counter T (S704). After the processing of S704, it is confirmed whether or not the value of the timer counter T is smaller than a preset standby time _Tmax (for example, 10 seconds) (T < _Tmax ) (S705).

When the value of the timer counter T reaches _Tmax (T ≧ _Tmax ) (S705: No) as a result of the confirmation in the process of S705, a display notifying the user that the file has not been received is displayed on the display unit 117. Error processing to be performed is performed (S709), and this file reception processing is terminated. That is, if either the song data file or the error file is not received within a predetermined time after the information file is transmitted to the mobile phone 200, the file is not waited for the receipt of the song data file and the error file. The reception process ends. Here, the fact that the song data file or the error file is not received from the mobile phone 200 indicates that a communication failure has occurred or that the magic number or model data included in the information file is not compatible with the application (S604). , S606). Therefore, when the electronic musical instrument 100 is not compatible with this performance information transfer system, useless transfer processing is not performed, and useless song data is not written in the flash ROM 113 of the electronic musical instrument 100.

On the other hand, if the value of the timer counter T has not reached _Tmax (T < _Tmax ) as a result of the confirmation in S705 (S705: Yes), it is confirmed whether a file has been received (S706). As a result of checking in S706, if the file has not been received yet (706: No), the process returns to S704, and until the value of the timer counter T reaches _Tmax or the file is received, S704 to S706. Repeat the process and wait.

  If the file is received as a result of the confirmation in S706 (S706: Yes), it is confirmed whether or not the received file is a song data file (S707). If the received file is a song data file as a result of the confirmation in S707 (S707: Yes), the received song data file is stored in the flash ROM 113 (S708). Here, in the processing of S708, processing may be performed such that the data is first stored in the RAM 112, which is a temporary memory, and then stored in the flash ROM 113. After the process of S708, this file reception process is terminated. It should be noted that the song data file stored in the flash ROM 113 in the process of S708 is selected when the user selects a desired song data file and executes a performance after the file receiving process is completed, and the selected song data is stored in the sound source 114. An automatic performance can be performed by inputting and generating a musical sound. Alternatively, an automatic performance may be performed based on the song data file stored in the flash ROM 113 before the file reception process is completed after the process of S708.

  On the other hand, if the received file is an error file indicating that the free memory capacity of the flash ROM 113 is insufficient as a result of checking in the process of S707 (S707: No), the flash file is flashed according to the error number included in the received error file. An error process is performed to display on the display device 117 to notify the user that the free space in the ROM is insufficient (S709), and the file reception process is terminated. In this case, in the error process (S709), in order to secure the free space of the flash ROM 113, a display prompting the user to delete the song data file that has already been stored may be performed. Information regarding various errors is displayed on the display device 117 by the error processing in S709, so that the user can know the cause of the error.

  As described above, according to the cellular phone 200 of the present invention, when the electronic musical instrument 100 is instructed to transmit a song data file, first, the electronic musical instrument 100 is requested to transmit an information file, and the request is made. Accordingly, whether or not to transmit the song data file is controlled in accordance with the contents of the information file returned from the electronic musical instrument 100. Therefore, if the free memory capacity of the electronic musical instrument 100 is insufficient with respect to the data size of the song data, or if the model of the electronic musical instrument 100 is not compatible with this performance information transfer system, the song data file is not transferred. Therefore, it is possible to suppress cancellations during transfer due to insufficient free memory at the transfer destination, or to prevent transfer to an unspecified number of electronic devices, so that song data can be copied illegally. Can be suppressed. That is, since whether or not to transfer the song data file is controlled according to the information file of the electronic musical instrument 100, it is possible to control the transfer of song data that cannot be controlled by the communication standard or communication protocol.

  In addition, according to the mobile phone 200 of the present invention, when the contents of the file received from the electronic musical instrument 100 satisfy a predetermined condition, downloading of the song data file from the server 300 is permitted.
