(6) Flow of processing of musical instrument cooperation program

Next, a flow of processing of the instrument cooperation program PB which operates on the tablet 5 will be described. Fig. 6 is a flowchart of instrument cooperation processing executed by the instrument cooperation program PB. First, the state acquiring unit 513 of the tablet 5 determines whether or not the communication between the tablet 5 and the electronic keyboard instrument 1 is established (step S11). If it is determined that the communication between the tablet 5 and the electronic keyboard instrument 1 is established, the state obtaining section 513 then determines whether or not the performance assisting program PC is started up on the tablet 5 (step S12).

When it is determined that the performance assisting program PC is started, the invalidation instructing unit 514 performs the invalidation process for the specific operation unit 12B of the electronic keyboard instrument 1 (step S13). Specifically, the invalidation instructing unit 514 acquires the identification information ID from the storage device 506. Then, the invalidation instructing section 514 transmits an invalidation instruction to the tablet 5 via the communication interface 507 in accordance with the identification information ID. If it is determined in step S11 that the communication between the tablet 5 and the electronic keyboard instrument 1 is not established, and if it is determined in step S12 that the performance support program PC is not activated, the process returns to step S11.

(7) Flow of processing of tablet cooperative program

Next, a flow of processing of the tablet cooperative program PA operating in the electronic keyboard musical instrument 1 will be described. Fig. 7 is a flowchart of the tablet cooperation process executed by the tablet cooperation program PA. First, the invalidation unit 112 of the electronic keyboard instrument 1 determines whether or not an invalidation instruction including the identification information D1 is received from the tablet 5 via the communication interface 107 (step S21). That is, it is determined whether or not the invalidation instruction transmitted in step S13 in fig. 6 has been received. When receiving the invalidation instruction including the identification information ID, the invalidation unit 112 invalidates the specific operation unit 12B among the plurality of operation units 12B (step S22). Specifically, the invalidation unit 112 instructs the reception unit 111 not to receive an operation from the specific operation unit 12B. In response to this, the receiving unit 111 stops receiving the instruction from the specified specific operation unit 12B. Further, the invalidation unit 112 gives an instruction to change the display form to the specific operation unit 12B. In response to this, the specific operation unit 12B changes the display mode, and the player is clearly shown that the specific operation unit 12B is invalidated. Examples of the change of the display mode include turning off an LED and turning off a touch panel.

The specific operation unit 12B invalidated by the invalidation unit 112 is stored in advance as setting information in the storage device 106, the ROM 103, or the like. For example, as the specific operation unit 12B, all the operation units 12B except the power supply operation unit are set. In this case, all of the plurality of operation units 12B of the electronic keyboard instrument 1 except for the power supply operation unit are invalidated along with the connection of the tablet 5. The invalidation unit 112 invalidates at least 1 operation unit 12B of the plurality of operation units 12B included in the electronic keyboard instrument 1. The invalidation unit 112 may invalidate all of the plurality of operation units 12B included in the electronic keyboard instrument 1.

The invalidation unit 112 may not execute the invalidation process of the specific operation unit 12B when the identification information ID acquired from the tablet 5 is not included in the registered ID. For example, the invalidation process of the specific operation unit 12B can be executed only when a connection to the tablet 5 registered in advance is received.

Next, the setting unit 113 of the electronic keyboard instrument 1 acquires the setting parameters SP stored in the storage device 106, and transmits the acquired setting parameters SP to the tablet 5 via the communication interface 107 (step S23). That is, the setting parameters SP are transmitted to the tablet 5 so that the current setting contents of the electronic keyboard instrument 1 are reflected on the tablet 5.

Next, the setting unit 113 of the electronic keyboard instrument 1 determines whether or not the end notification of the performance assisting program PC and the setting parameter SP are received from the tablet 5 (step S24). Upon receiving the notification of the end of the performance assisting program PC and the setting parameter SP, the setting unit 113 updates the setting parameter SP stored in the storage device 106 based on the received setting parameter SP (step S25). Thus, the contents of the settings changed on the tablet 5 are reflected on the electronic keyboard instrument 1. Next, the setting unit 113 instructs the receiving unit 111 to activate the specific operation unit 12B that has been deactivated (step S26). Thereby, receiving unit 111 returns to a state of receiving operations of all operation units 12B. The setting unit 113 instructs the specific operation unit 12B to return the display mode to the original state. This restarts the lighting of the LEDs and the touch panel, and the player can recognize that all the operation units 12B are activated.

(8) Flow of processing of performance support program

Next, a flow of processing of the performance assisting program PC that operates on the tablet 5 will be described. Fig. 8 is a flowchart of the performance assisting process executed by the performance assisting program PC. First, the setting unit 512 of the tablet 5 receives the setting parameter SP from the electronic keyboard instrument 1 via the communication interface 507. The setting unit 512 stores the received setting parameter SP in the storage device 506 (step S31). That is, the setting parameter SP transmitted from the electronic keyboard instrument 1 in step S23 of fig. 7 is reflected on the tablet 5.

Next, the receiving unit 511 of the tablet 5 determines whether or not the operation unit 51B has received an operation on the electronic keyboard instrument 1 (step S32). That is, it is determined whether or not the setting operation for the electronic keyboard instrument 1 is performed by the player who operates the touch panel display 51. When the receiving unit 511 receives an operation for the electronic keyboard instrument 1, the setting unit 512 executes a process corresponding to the received operation (step S33). For example, the setting unit 512 transmits an instruction corresponding to the received setting operation to the electronic keyboard instrument 1 via the communication interface 507. In the electronic keyboard instrument 1, the setting operation is performed in accordance with the instruction. For example, the setting of the performance mode specified in the tablet 5 is executed in the electronic keyboard musical instrument 1. In addition, the setting unit 512 updates the setting parameter SP stored in the storage device 506 in accordance with the received setting operation.

Next, the setting unit 512 of the tablet 5 determines whether or not an instruction to end the performance support program PC has been received (step S34). When receiving the end instruction of the performance support program PC, the setting unit 512 transmits the setting parameters SP stored in the storage device 506 to the electronic keyboard instrument 1 via the communication interface 507 (step S35). In the electronic keyboard instrument 1, the update process of the setting parameters SP is executed through steps S24 and S25 shown in fig. 7. Thus, the contents of the setting parameters SP updated during the operation of the tablet 5 are reflected on the electronic keyboard instrument 1. After the above processing, the performance assisting program PC ends.
