Set over data sets parameters of a tone constituting a music piece to be reproduced by the automatic playing unit 46. When one of the registration switches 13 is pressed while a light switch (not shown) is pressed, the registration setting unit 42 changes the parameters as previously set for the one switch. Associate actions.

  At this time, the parameter updating unit 43 executes the operation to change the parameter when the automatic performance is not performed or when the operated switch does not correspond to the operation for changing the musical sound parameter related to the automatic performance. To do. Further, the parameter update unit 43 does not change the parameter when the operated switch corresponds to the operation of changing the musical sound parameter related to the automatic performance during the automatic performance.

  At this time, the guide unit 48 lights the LED of the switch whose parameter is changed by the parameter update unit 43 when operated in the registration switch 13 in red, and the parameter is updated by the parameter update unit 43 even if operated. The LED of the switch that is not changed is lit in blue.

  The operation of the electronic musical instrument 1 includes an operation of setting an operation on the switch and an operation of changing a parameter value related to a musical sound.

  In the operation of setting the operation to the switch, first, the user performs a keyboard conductor area 14, a first lower pedal solo area 15, a second lower pedal solo area 16, a first lower orchestra area 17, and a second lower orchestra area 18. Upper party percussion area 19, tibia control area 20, upper special area 21, lower special area 22, first upper orchestra area 23, second upper orchestra area 24, first upper solo area 25, and second upper solo area 26 The switches arranged in the pedal orchestra area 27, the auto play orchestra rhythm area 28, the auto play orchestra accompaniment area 29 and the LCD area 31 are operated by the performance section 45. Set the parameters of a tone constituting a music piece to be produced, it sets the parameters of a tone constituting a music piece to be reproduced by the automatic playing unit 46. This setting can be executed regardless of whether the electronic musical instrument 1 is performing automatically. When a light switch (not shown) is pressed, one of the switches of the knee lever 4, the left foot switch 6, the right foot switch 7, and the registration switch 13 is pressed when the electronic musical instrument 1 is pressed. The operation of changing the parameter is associated with the one switch as previously set.

  The operation for changing the value of the parameter relating to the musical sound includes a first operation and a second operation. The first operation is as follows: keyboard conductor area 14, first lower pedal solo area 15, second lower pedal solo area 16, first lower orchestra area 17, second lower orchestra area 18, apparel percus area 19, and tibia. Control area 20, upper special area 21, lower special area 22, first upper orchestra area 23, second upper orchestra area 24, first upper solo area 25, second upper solo area 26, pedal orchestra area 27, and auto play orchestra This is performed using a plurality of switches arranged in the rhythm area 28, the auto play orchestra accompaniment area 29, and the LCD area 31. The second operation is executed using the knee lever 4, the left foot switch 6, the right foot switch 7, and the registration switch 13.

  In the first operation, the user performs a keyboard conductor area 14, a first lower pedal solo area 15, a second lower pedal solo area 16, a first lower orchestra area 17, a second lower orchestra area 18, and an upper beer percussion area 19. And tibia control area 20, upper special area 21, lower special area 22, first upper orchestra area 23, second upper orchestra area 24, first upper solo area 25, second upper solo area 26 and pedal orchestra area 27 Musical sounds constituting the music played by the performance unit 45 by operating switches arranged in the auto play orchestra rhythm area 28, the auto play orchestra accompaniment area 29 and the LCD area 31. Set parameters to set the parameters of a tone constituting a music piece to be reproduced by the automatic playing unit 46. This setting can be executed regardless of whether the electronic musical instrument 1 is performing automatically.

  FIG. 5 shows the second operation. This operation is started when the registration switch 13 is pressed. When the registration switch 13 is pressed, the electronic musical instrument 1 first determines whether or not an automatic performance is in progress (step S1). Whether the electronic musical instrument 1 is performing an automatic performance (step S1, YES), refers to the registration table 51, and whether or not the pressed switch corresponds to an operation for changing a musical sound parameter related to the automatic performance. Is determined (step S2).

  When the electronic musical instrument 1 is not playing automatically (step S1, NO), or when the pressed switch does not correspond to an operation for changing a musical sound parameter relating to automatic performance (step S2, NO), the electronic musical instrument 1 is pressed. The operation corresponding to the selected switch is executed to change the parameter (step S3). When the electronic musical instrument 1 is performing automatically (step S1, YES), when the pressed switch corresponds to an operation for changing a musical sound parameter relating to automatic performance (step S2, YES), the parameter is not changed. .

  When using both the upper keyboard 11 and the lower keyboard 12, the user may erroneously operate the registration switch 13 disposed between the upper keyboard 11 and the lower keyboard 12. When using the expression pedal 5, the user may erroneously operate the knee lever 4, the left foot switch 6, and the right foot switch 7. When using the pedal keyboard 8, the user may operate the knee lever 4 by mistake. According to such an electronic musical instrument 1, when a user erroneously operates any one of the knee lever 4, the left foot switch 6, the right foot switch 7, and the registration switch 13 during automatic performance, the musical sound by automatic performance is obtained. Is not changed, and musical sound parameter changes unintended by the user can be reduced.

  The electronic musical instrument 1 can also perform the operation shown in FIG. 5 with respect to a switch arranged adjacent to the keyboard when the front panel 3 includes only one keyboard.

  The electronic musical instrument 1 relates to a switch other than a switch in which which parameter is to be changed by the user, that is, a switch in which which parameter is to be changed by the user cannot be set. It is also possible to execute the operation.
