  The MIDI interface circuit 34 can be connected to a MIDI compatible external device 41 such as another electronic musical instrument or a personal computer, and the electronic musical instrument EL can communicate various programs and data with the external device 41. Similar to the communication interface circuit 17 of the personal computer apparatus PC, the communication interface circuit 35 is configured to be communicably connected to the server computer apparatus SV. The electronic musical instrument EL can receive various services including various music data from the server computer apparatus SV.

  Next, the operation of the embodiment configured as described above will be described. First, the creation operation of the connection environment setting file and the connection file by the personal computer apparatus PC will be described. The user operates the keyboard 11 to cause the computer unit 14 to execute the setting information input program shown in FIG. The execution of this program is started in step S10, and the computer unit 14 displays a setting information input screen on the display 12 in step S11. As shown in FIG. 5, the setting information input screen is a screen for the user to input connection environment setting information and connection information for connecting the electronic musical instrument EL to the server computer apparatus SV in a communicable manner.

  The connection environment setting information and the connection information will be described with an example. The connection environment setting information includes LAN environment setting information (IP address, IP address, and electronic instrument EL if necessary). Subnet mask, DHCP usage settings, gateway IP address, DNS IP address, etc.), wireless LAN setting information (SSID, channel, information related to encryption, etc.), model name and other setting information (proxy settings, etc.), etc. Is included. The connection information is login information including a user ID and a password. The initial values and item names of these various types of information are predetermined and embedded in the setting information input program, and are associated with the setting items of the connection environment setting information and the connection information when the setting information input screen is displayed. The initial value is temporarily stored in the RAM 14d and displayed on the display 12.

  In this state, the user uses the keyboard 11 to move the cursor to each setting item and then input connection environment setting information or connection information. In response to this information input operation, in step S12, the computer unit 14 changes the connection environment setting information or connection information stored in the RAM 31d to the input connection environment setting information or connection information. As long as the changing operation is continued, the computer unit 14 determines “No” in step S13, and continues to change the connection environment setting information and the connection information by the process of step S12. When the user finishes changing the connection environment setting information and the connection information and instructs to save the setting information using the keyboard 11, the computer unit 14 determines "Yes" in step S13, To step S14 and subsequent steps.

  In step S14, the computer unit 14 reads out an encryption key corresponding to a decryption key in the electronic musical instrument EL described later, and in step S15, uses the read out encryption key to obtain connection information (user ID and password). Encrypt so that it can be decrypted by the electronic musical instrument EL. In this case, the encryption key may be embedded for each model in the setting information input program, and the corresponding encryption key may be read according to the model name input by the user. A setting information input program may be prepared for each model, and when this setting information input program is executed, an encryption key corresponding to the corresponding model may be automatically read out. In this case, it is not necessary to input the model name. Furthermore, the same encryption key may be used in all the product groups including a plurality of models. In short, an encryption key that can be decrypted by the electronic musical instrument EL may be used. In step S16, the encrypted connection information is included in the connection file, and the connection file is stored in a predetermined storage location (for example, a top directory) of the removable medium RM.

  After the process of step S16, the computer unit 14 reads fixed connection environment setting information belonging to items other than the items displayed on the display unit 12 in step S17. The fixed connection environment setting information includes, for example, the URL of a dedicated server that provides a service to the electronic musical instrument EL, the URL of a dedicated server for maintenance, and the like. This is so that when the user tries to select music data on the server, input by the user of the URL providing the service can be omitted. In addition, when a special operation for maintenance is performed, the URL for maintenance can be automatically accessed.

  Next, in step S18, the computer unit 14 uses the encryption key read out in the process of step S14, and the connection environment setting information belonging to the item displayed on the display device 12 and the fixed connection environment setting information. Is encrypted. In step S19, the encrypted connection environment setting information is included in the connection environment setting file, and the connection environment setting file is stored in a predetermined storage location (for example, the top directory) of the removable medium RM. In step S20, the execution of the setting information input program is terminated. Accordingly, the connection information and the connection environment setting information are stored in the removable medium RM according to the model of the electronic musical instrument EL.

  Next, a connection operation for connecting the electronic musical instrument EL to the server computer apparatus SV in a communicable manner and a connection environment setting operation for the connection will be described. After the power switch is turned on, the user causes the computer unit 31 to start executing the main program shown in FIG. After the execution of the main program is started, the computer unit 31 repeatedly executes a circulation process including steps S21 to S24. In step S21, the computer unit 31 determines whether an operator for network setting processing has been operated, an operator for connection to the server computer apparatus SV has been operated, or an operator for other processing. It is determined whether has been operated. When an operator for network setting processing is operated, the computer unit 31 executes a network setting processing routine in step S22.

  The execution of the network setting processing routine is started in step S30 of FIG. 7, and the computer unit 31 determines whether or not the removable media RM is mounted on the removable media mounter 33 in step S31. If the removable media RM is loaded in the removable media mounter 33, the computer unit 31 determines “Yes” in step S31, and executes the removable read processing routine in step S32. This removable read processing routine is started in step S50 of FIG.

  After the execution of the removable read processing routine is started, the computer unit 31 determines whether or not a connection environment setting file exists in a predetermined storage location (for example, a top directory) of the removable medium RM in step S51. If the connection environment setting file exists, the computer unit 31 determines “Yes” in step S 51, and in step S 52, a setting information reading screen (in which the user is asked to read the setting information). FIG. 10A is displayed on the display 23.

  In step S53, an operation indicating whether or not setting information is read, that is, as shown in FIG. 10A, the panel operators 22a to 22d arranged near the display 23 constituting the panel operator group 22 as shown in FIG. Among them, the operation of the panel operators 22b and 22d is awaited. If the panel operator 22b, that is, the reading operator is operated, the computer unit 31 determines “Yes” in step S53, and executes the processes of steps S54 to S55. On the other hand, if the panel operator 22d, that is, the reading canceling operator is operated, the computer unit 31 makes a “No” determination at step S53, and ends the execution of the removable reading processing routine at step S57.

  In step S54, a decryption key for decrypting the connection environment setting information in the connection environment setting file is obtained. The decryption key is stored in advance in the ROM 31c when the electronic musical instrument EL is shipped from the factory, and is provided for each type of electronic musical instrument EL or for each product. Next, the computer unit 31 decrypts the connection environment setting information in the connection environment setting file using the acquired decryption key. Then, in step S56, the computer unit 31 uses the decrypted connection environment setting information to set a network environment for connecting the electronic musical instrument EL via the communication network CN. In step S57, the removable read processing routine is terminated. In this case, the connection environment of the network connection device NT is mainly set, but if the connection environment of the electronic musical instrument EL itself is necessary, the connection environment is also set.

  Returning to the description of the network setting routine in FIG. 7 again, after the processing in step S31 or step S32, the computer unit 31 can connect the electronic musical instrument EL to the server computer apparatus SV in a communicable manner in step S33. A display screen for displaying the first predetermined setting items necessary for setting the network connection environment is displayed on the display unit 23, and the cyclic processing including steps S34 to S40 is repeatedly executed. . When the user instructs the end of the execution of the network setting process routine by operating the panel operator group 22 during the circulation process, the computer unit 31 determines “Yes” in step S40 and ends the execution of the network setting routine. To do. Accordingly, when the network connection environment is set by the connection environment setting information stored in the removable medium RM by the processing of steps S31 and S32, the user instructs execution of the network setting processing routine. Simply set up the network connection environment.

  In addition, when the removable media RM is loaded into the removable media mounter 33 during the circulation process of steps S34 to S39, the computer unit 31 determines “Yes” in step S38, and described above in step S39. The removable read processing routine of step S32 is executed. Also in this case, if the connection environment setting file including the connection environment setting information is stored in the removable medium RM, and the user selects the network environment setting based on the perceptual environment setting information, the network is set in the same manner as described above. The environment is automatically set. When the user gives an instruction to end the execution of the network setting processing routine by operating the panel operator group 22, the computer unit 31 determines “Yes” in step S40 and ends the execution of the network setting routine. Therefore, also in this case, it is possible to easily set the network connection environment using the connection environment setting information stored in the removable medium RM.

  On the other hand, if the removable media RM is not mounted on the removable media mounter 16, the connection environment setting file does not exist in the mounted removable media RM, or it is not selected by the user even though it exists. The network connection environment is set using the panel operator group 22 by the processing of steps S34 to S37. For example, when the panel operators 22e and 22f arranged in the vicinity of the display 23 shown in FIG. 10 in the panel operator group 22 are operated, the current display screen is determined in advance by the processing of steps S34 and S35. It is sequentially switched to the ascending order side and the descending order side according to the order. This operation and display switching means switching of the setting items of the connection environment setting information. In the state of the display screen of the desired setting item (for example, the IP address item display screen of FIG. 10B), FIG. When the panel operator 22c arranged in the vicinity of the display 23 shown in FIG. 10 is operated, the screen is switched to the IP address input screen of FIG.

  When the user instructs to input or change the IP address by operating the panel operators 22a to 22d and the rotary switch 22g arranged in the vicinity of the display device 23, the IP address is changed by the processing of steps S36 and S37. The The rotary switch 22g sequentially changes a value or a symbol by rotation. Then, after changing the setting items of the connection environment setting information, the connection environment setting information is set one after another by operating the panel operators 22a to 22g in relation to the display state of the display unit 23 as described above. . In inputting or changing the connection environment setting information, other panel operators of the panel operator group 22 may be used as necessary. In this way, the network connection environment is set according to the operation of the panel operator group 22 of the electronic musical instrument EL. Such a setting operation is not limited to the display 23, and the type of the panel operator group 22 is not limited. Since the number is limited, it takes time to input the connection environment setting information.

  Returning to the description of the main program in FIG. When the panel operator group 22 for connection to the server computer apparatus SV is operated, the computer unit 31 executes a server connection processing routine in step S23. This server connection processing routine is started in step S60 of FIG. 9, and the computer unit 31 determines whether or not the removable media RM is mounted on the removable media mounter 33 in step S61. If the removable media RM is loaded in the removable media loader 33, the computer unit 31 determines “Yes” in step S61, and proceeds to step S62. In step S62, it is determined whether a connection file exists in a predetermined storage location (for example, the top directory) of the removable medium RM. If the connection file exists, the computer unit 31 determines “Yes” in step S62, and advances the program to steps S63 and S64.

  In step S63, a decryption key for decrypting the connection information in the connection file is obtained. This decryption key is the same as the decryption key for decrypting the connection environment setting information. In step S64, the connection information in the connection file is decrypted using the obtained decryption key, and the user ID and password are extracted. After the processes of steps S63 and S64, the computer unit 31 executes a login process for the server computer apparatus SV via the network connection device NT and the communication network CN in step S65. In this case, since the network connection device NT is set as described above, the electronic musical instrument EL is communicably connected to the server computer device SV. As described above, as a result of using the connection information (user ID and password) stored in the removable medium RM, the electronic musical instrument EL can be connected to the server computer device SV in a simple operation.

  After the process of step S65, the electronic musical instrument EL obtains desired data from the server computer apparatus SV in step S66. In this case, the obtaining operation is performed by operating the panel operators 22a to 22g in association with the display state of the display device 23, thereby receiving provision of desired music data or the like from the server computer apparatus SV. For example, as shown in FIGS. 10D and 10E, a screen for selecting a folder storing music data and a screen for selecting music data in the same folder are displayed on the display 23, and the music data is stored in the server computer. Obtain from device SV.

  On the other hand, if the removable media RM is not mounted on the removable media mounter 16 or the connection information is not included in the removable media RM, the computer unit 31 determines “No” in step S61 or step S62. In step S67, connection information (user ID and password) is input. Also in this case, for example, the display screen of the setting items of the connection information is switched by the operation of the panel operators 22e and 22f in FIG. Then, a user ID and a password are input by operating the panel operators 22a to 22g in FIG. 10 (see FIG. 10F). Therefore, also in this case, the electronic musical instrument EL is communicatively connected to the server computer apparatus SV by the process of step S65 described above. However, in this case, it takes time to input the user ID and password compared to using the removable medium RM.

  Returning to the description of the main program in FIG. When the panel operator 22 for purposes other than the above-described network environment setting and connection to the server computer apparatus SV is operated, the computer unit 31 executes other processing in step S24. Other processing includes selection and playback of music data stored in the built-in storage device 32, setting of tone color, volume and effect for performance sound in the electronic musical instrument EL, and performance operation by operating the panel operator group 22. This is a general process as an electronic musical instrument EL, such as generation of a musical sound signal according to performance by the child group 21.

  As can be understood from the above operation description, according to the above embodiment, the connection information necessary for connecting the electronic musical instrument EL to the server computer device SV on the communication network CN so as to be able to communicate with each other, or the environment for the connection. Connection environment setting information necessary for the setting is supplied to the electronic musical instrument EL via the removable medium RM. In the electronic musical instrument EL, the environment such as the network connection device NT is set using the connection environment setting information. Further, the electronic musical instrument is connected to the server computer apparatus SV on the communication network CN using the connection information so as to be able to communicate. Therefore, even if the display 23 provided in the electronic musical instrument EL is small and the number and type of the panel operator groups 22 are small, the setting of the connection environment or the connection can be easily realized. Furthermore, since the connection information or the connection environment setting information is encrypted and stored in the removable medium RM, there is no problem of information leakage and unauthorized use.

  Furthermore, in carrying out the present invention, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the object of the present invention.

  For example, in the above embodiment, a connection file for storing connection information and a connection information file for storing connection environment setting information are provided separately. However, these two files may be combined into one setting file and the connection information and connection environment setting information may be stored in one setting file. In this case, the processing in step S16 in FIG. 4 is deleted, and in step S19, the connection information is included in one setting file together with the connection environment setting information, and stored in a predetermined position on the removable medium. Good. In the removable read processing routine of FIG. 8, the presence of the setting file is confirmed in step S51, and the connection environment setting information in the setting file is read and decoded in step S55. In the server connection processing routine of FIG. 9, the presence of the setting file is confirmed in step S62, and the connection information in the setting file is read and decoded in step S64.

  Next, a modified example in which the setting information input program of FIG. 4 executed by the personal computer apparatus PC of the above embodiment is modified will be described. In this modification, the personal computer apparatus PC (that is, the client computer apparatus) acquires the encrypted connection information and connection environment information in cooperation with the server computer apparatus SV. Note that the connection information and the connection environment setting information are the same as those in the above-described embodiment. However, in the present modification, hereinafter, both the connection information and the connection environment setting information are simply referred to as setting information.

  The user accesses the personal computer apparatus PC to the server computer apparatus SV and starts execution of the setting processing program of FIG. 11 in step S70. After the start, in step S71, the computer unit 31 requests the server computer device SV for a setting information input screen for inputting setting information. The computer unit 14 in the server computer apparatus SV starts execution of the setting information generation program in step S80 of FIG. 11, and in step S81, information indicating the requested setting information input screen is sent to the personal computer apparatus PC. Send. In the personal computer PC, the computer unit 14 receives the information representing the setting information input screen transmitted from the server computer SV in step S72, and uses the received information to enter the setting information input screen. Is displayed on the display 12. This setting information input screen is the same as that in the above embodiment, and is a screen for the user to input setting information as shown in FIG.

  Next, the computer unit 14 inputs or changes the setting information by the process of step S73 similar to the process of step S12 of FIG. Also in this case, the user inputs or changes the setting information by operating the keyboard 11 while viewing the display on the display device 12. If the user does not instruct the saving of the setting information, the input or change process of the setting information is continued by the circulation process including steps S73 and S74 based on the determination of “No” in step S74. On the other hand, when the storage of the setting information is instructed, the computer unit 14 determines “Yes” in step S74, and transmits the input or changed setting information to the server computer apparatus SV in step S75.

  The server computer apparatus SV receives the transmitted setting information in step S82, and reads setting information other than the received setting information in step S83. The setting information other than the received setting information corresponds to the fixed connection environment setting information read in step S17 of FIG. 9 of the above embodiment, and is prepared in advance in the server computer apparatus SV. Next, in step S84, the server computer apparatus SV encrypts the received setting information and the read setting information so that the electronic musical instrument EL can be decrypted using an encryption key. This encryption key corresponds to the decryption key of the electronic musical instrument EL, as in the case of the above embodiment, and is prepared in advance in the server computer apparatus SV. Then, the server computer apparatus SV transmits the encrypted setting information to the personal computer apparatus PC in step S85, and ends the execution of the setting information generation program in step S86.

  In the personal computer apparatus PC, the computer unit 14 receives the transmitted setting information in step S76, and includes the received and encrypted setting information in the setting file in step S77. Then, the setting file is stored in a predetermined position (for example, the top directory) of the removable medium RM, and the execution of the setting information input program is terminated in step S78.

  Even in the modified example configured as described above, the connection information necessary to connect the electronic musical instrument EL to the removable media RM to the server computer device SV on the communication network CN so as to be able to communicate with each other, or the environment setting for the connection. Stores necessary connection environment setting information. Therefore, even if the display 23 provided in the electronic musical instrument EL is small and the number and type of the panel operator groups 22 are small, the setting of the connection environment or the connection can be easily realized. Furthermore, since the connection information or the connection environment setting information is encrypted and stored in the removable medium RM, there is no problem of information leakage and unauthorized use.

  In this modification, the connection information and the connection environment setting information are stored in one setting file. However, as in the above embodiment, the connection information is stored in the connection file and the connection information is connected. The environment setting information may be stored in the connection environment file. Further, in this modification, the server computer apparatus SV that encrypts the setting information is the same as the server computer apparatus that the electronic musical instrument EL receives services such as provision of music data, but the two server computer apparatuses are independent of each other. You may comprise by the separate thing.

  In the embodiment and the modification, the connection environment setting information and the encryption key and the decryption key for the connection information are made common. However, the encryption key and the decryption key for the connection environment setting information and the connection information may be different from each other. Further, in the connection environment setting information, in the connection information, different encryption keys and decryption keys may be used for each information.

  Furthermore, in the above-described embodiment, the present invention is applied to the electronic musical instrument EL that employs a keyboard as the performance operator group 21. However, instead of the key, a performance operator that designates a pitch using a simple switch, touch switch, or the like. You may apply this invention to the electronic musical instrument which employ | adopted. In particular, the present invention can be applied to electronic musical instruments such as electronic stringed musical instruments and electronic wind instruments regardless of the form of the electronic musical instrument.
