Next, the operation of the electronic musical instrument 10 will be described. The electronic musical instrument 10 has a performance mode in which the operator is used to perform, and a setting mode in which various functions are set. The operation of setting the function of the manipulator will be described below. The user first operates the cursor key CK, the touch panel TP, etc. to shift the operation mode of the electronic musical instrument 10 to the setting mode, and selects the performance part PT _n to be set. Then, an image as shown in FIG. 6 is displayed on the display unit 13. That is, the display 13 displays an image for setting the function of the manipulator. A display filter button B1 and an auto select button B2 are arranged above the image. Further, below the display filter button B1 and the auto select button B2, a display area A1 for displaying an image representing the setting data set SS _n is arranged. In the display area A1, as will be described below, an image representing one or a plurality of setting data SD _m regarding the manipulator to be set among the setting data SD _m=1 to setting data SD _m=16 is displayed. ..

The display filter button B1 is a button for selecting an operator to be set. When the user touches the display filter button B1, a list of operator names is displayed as shown in FIG. The user operates the touch panel TP, the cursor key CK, etc. to select an operator to be set. Then, the selected operator is determined as a setting target, and the name of the selected operator is displayed on the display filter button B1. For example, in the example of FIG. 7, the expression pedal is selected. Therefore, in this case, the expression pedal is determined as the setting target, and "expression pedal" is displayed on the display filter button B1 as shown in FIG.

The auto select button B2 is a toggle switch set to an on state or an off state. That is, each time the user touches the auto select button B2, the ON state and the OFF state are alternately switched. When the user operates a desired operator while the autoselect button B2 is in the ON state, the operated operator is determined as a setting target, and the name of the operated operator is displayed on the display filter button B1. It The operation mode when the auto select button B2 is set to the on state corresponds to the predetermined operation mode of the present invention.

That is, when the CPU 12a starts the setting target determination process in step S10 shown in FIGS. 9A and 9B, it determines in step S11 whether or not the autoselect button B2 is touched. When the auto select button B2 is not touched, the CPU 12a determines “No” and advances the process to step S17 described later. On the other hand, when the auto-select button B2 is touched, the CPU 12a determines “Yes” and determines in step S12 whether the auto-select button B2 is on. When the auto select button B2 is in the on state, the CPU 12a determines “Yes”, sets the auto select button B2 in the off state in step S13, and advances the process to step S17. On the other hand, when the auto select button B2 is in the off state, the CPU 12a determines “No” and sets the auto select button B2 in the on state in step S14. Next, in step S15, the CPU 12a determines whether or not the list of the names of the operators is being displayed. When the list of operator names is not displayed, the CPU 12a determines “No” and advances the process to step S17. On the other hand, when the list of the names of the operators is displayed, the CPU 12a determines “Yes”, and sets the list of the names of the operators to non-display in step S16.

Next, the CPU 12a determines in step S17 whether or not the operator is operated. When the operator is not operated, the CPU! 2a determines “No” and advances the process to step S22 described later. On the other hand, when the operator is operated, the CPU 12a determines “Yes”, and determines in step S18 whether or not the autoselect button B2 is in the ON state. When the auto select button B2 is in the off state, the CPU 12a determines “No” and advances the process to step S22. On the other hand, when the auto select button B2 is in the ON state, the CPU 12a determines “Yes” and determines the operated operator as the operator to be set in step S19. Next, in step S20, the CPU 12a determines whether or not the list of the names of the operators is being displayed. When the list of the names of the operators is not displayed, the CPU 12a determines “No” and advances the process to step S22. On the other hand, when the list of operator names is displayed, the CPU 12a determines “Yes” and sets the operator name list to non-display in step S21.

Next, the CPU 12a determines whether or not the display filter button B1 is touched in step S22. When the display filter button B1 is not touched, the CPU 12a determines “No” and advances the process to step S24. On the other hand, when the display filter button B1 is touched, the CPU 12a determines “Yes” and displays a list of the names of the operators in step S23.

Next, in step S24, the CPU 12a determines whether or not the name of one operator in the list of operator names has been touched. When the list of the names of the operators is not touched, the CPU 12a determines “No” and advances the process to step S27. On the other hand, when the name of one operator in the list of operator names is touched, the CPU 12a determines “Yes” and selects the operator selected by the touch in step S25. Determined as the operator to be set. Next, in step S26, the CPU 12a sets the list of operator names to non-display. Then, the CPU 12a ends the setting operator determination process in step S27, and returns to the main routine (not shown). The setting target determining process is sequentially executed in a state where the setting target operator has not been determined. The setting target determination process may be executed when some event (for example, the operation of the touch panel TP) occurs in a state where the setting target operator has not been determined.

When the operator to be set is determined as described above, the current setting content regarding the operator to be set is displayed in the display area A1. That is, among the setting data SD _m, setting data SD _m is selected, an image representing the setting data SD _m said selected is displayed in the display area A1 with source data SO _m that matches the target operating element .. When a plurality of parameters are assigned to the operator to be set (that is, when there are a plurality of setting data SD _m having the same source data SO _m ), an image showing the plurality of setting data SD _m in the display area A1. Is displayed. For example, in the example shown in FIG. 4, the source data _{SO m = 1} and setting data _{SD m = 3} the source data _{SO m = 3} in the setting data _{SD m = 1} are both "first Assignable". Therefore, as shown in FIG. 6, when the operator to be set is the “first assignable knob”, an image showing the setting data SD _m=1 and the setting data SD _m=3 is displayed in the display area A1. As shown in the figure, in the display area A1, images representing a plurality of setting data SD _m are displayed in a tab format . That is, the tab TB _m are provided corresponding to the respective setting data SD _m. Then, the entire selected one tab TB _m is displayed, the other tabs TB _m are located on the back side of the selected tab TB _m , and only the heading part located at the upper end thereof is displayed. There is. Touching the heading of the tab TB _m, it is possible to select the tab TB _m. FIG. 6 shows a state in which the tab TB _m=1 is selected.

A destination button B3 is displayed in the heading section of each tab TB _m . The destination data DN _m (that is, the parameter name) of the setting data SD _m is displayed on the destination button B3. Further, the main body portion of each tab TB _m, source buttons B4 and change curve button B5 is displayed. The source data SO _m (that is, the name of the operator) of the setting data SD _m is displayed on the source button B4. The display of the source button B4 matches the name of the operator determined as the setting target. The change curve button B5 displays change curve data CD _m (name of change curve data) of the setting data SD _m . Then, on the right side of the change curve button B5, the change curve of the graph corresponding to the variation curve data CD _m are displayed.

When changing the correspondence between the manipulator and the parameter, the following operation is performed. The manipulator (that is, the manipulator displayed on the source button B4) for manipulating the parameter (that is, the parameter displayed on the destination button B3) corresponding to the currently selected tab TB _m is changed to another manipulator. To change to, the user touches the source button B4 on the tab TB _m . Then, a list of operator names is displayed. When the user operates the touch panel TP, the cursor key CK or the like to select another operator, the source data SO _m of the setting data SD _m is rewritten to the identification data (name of the operator) of the other operator. Then, the setting target can be switched to the other operator. That is, the display of the display filter button B1 is switched to the name of the other operator. Also, among the setting data SD _m, setting data SD _m is selected, an image representing the setting data SD _m said selected is displayed in the display area A1 with source data SO _m that matches the target operating element ..

Further, when changing the parameter corresponding to the currently selected tab TB _m (that is, the parameter displayed on the destination button B3) to another parameter, the user needs to change the destination button B3 on the tab TB _m . Touch. Then, a list of parameter names is displayed. When the user operates the touch panel TP, the cursor key CK, etc. to select another parameter, the destination data DN _m of the setting data SD _m is rewritten to the identification data (parameter name) of the other parameter. Then, the display of the destination button B3 is changed to the name of the other parameter.

When changing the change curve of the currently selected tab TB _m , the user touches the change curve button B5 on the tab TB _m . Then, a list of the names of the change curves is displayed. When the user operates the touch panel TP, the cursor key CK, or the like to select another change curve, the change curve data CD _m of the setting data SD _m is rewritten with the identification data of the other change curve (change curve name). Then, the display of the change curve button B5 is changed to the name of the other change curve.

According to the electronic musical instrument 10 configured as described above, if the user operates the manipulator with the autoselect button B2 set to the ON state, the manipulator is determined as the setting target. That is, it is not necessary to touch the display filter button B1 to display a list of the names of the operators and use the touch panel TP, the cursor key CK or the like to select the operator to be set. Therefore, the user can easily set the function of the operator. In addition, there is no risk of erroneously selecting a setting target. In addition, even when the user forgets the type of parameter assigned to a certain operator, by operating the operator with the autoselect button B2 set to the ON state, the operator is assigned to that operator. You can easily check the types of parameters that are present.

Also, among the setting data SD _m, setting data SD _m is selected, an image representing the setting data SD _m said selected is displayed in the display area A1 with source data SO _m that matches the target operating element .. Since only the necessary information is displayed in the display area A1 in this way, the visibility of the display area A1 is good.

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

In the above embodiment, an example in which the present invention is applied to an electronic musical instrument (sound signal generating device) has been described, but the present invention may be applied to an electronic acoustic device other than an electronic musical instrument. In addition, the present invention has a signal generation unit (a part of an image or a part that generates one layer of an image composed of a plurality of layers) that generates a signal representing an image (still image or moving image). It is also applicable to a video signal generation device.

Further, for example, when the operator is operated in a state where the display filter button B1 is touched (or a state in which a list of operator names is displayed), the operated operator may be determined as a setting target. In this case, the operation mode in the state where the display filter button B1 is touched corresponds to the predetermined operation mode of the present invention. In this case, the auto select button B2 may be omitted.

In addition, when changing the manipulator that operates the parameter corresponding to the currently selected tab TB _m to another manipulator, if the manipulator is operated while the source button B4 is being touched, it corresponds to the tab TB _m . Parameters may be assigned to the operated controls. In this case, the operation mode in which the source button B4 is touched corresponds to the predetermined operation mode of the present invention.

In the above embodiment, setting of the data SD _m, setting data SD _m is selected, the image display area indicating the setting data SD _m said selected having a source data SO _m that matches the target operating element A1 is displayed in a tab format. Instead of this, a list of parameters assigned to the operator to be set may be displayed, and only the information related to the parameter selected from the list may be displayed.

Further, the auto select button B2 may be provided, for example, in the performance mode instead of the setting mode for setting the function of the operator. In this case, when the auto select button B2 is set to the ON state and the operator is operated, it is preferable that the information regarding the parameter assigned to the operator is displayed. According to this, the parameter assigned to the operator can be easily confirmed.

In the setting target determination process, when the auto select button B2 is in the on state, the list of the names of the operators may be kept displayed. That is, step S15 and step S16 may be omitted.
