It The up button C4 and the down button C5 are used to increase and decrease the parameters displayed in the display area, respectively. The button C6 is a next page button (more button) and is used for switching the display of the edit screen to the next page.

Next, the allocation of the user main screen will be described with reference to FIGS. In the following, an example will be described in which the data of the setting screen regarding the pressure depths of a plurality of tracks is assigned to the user main screen.

First, when the power of the electronic musical instrument 1 is turned on,
A default screen is displayed on the display unit 30. This default screen displays, for example, the tone color currently sounded by the keyboard 2. Edit switch 3 here
When 8 is pressed, the screen of the display unit 30 shifts from the default screen to the edit menu screen. As shown in FIG. 5, the edit menu screen is divided into eight display areas “COMMON”, “DCO”, “DCF”, “DCA”,
"Additive", "LFO &Copy","Control" and "Eff"
ect ”.

Next, the display screen 30 is operated so that an edit screen regarding the pressure depth is displayed. Since the pressure depth is one of the parameters included in “Control”, “Co” is displayed on the edit menu screen.
The button B7 corresponding to the display area A7 of "ntrol" is pressed. As a result, the edit screen for one of the parameters included in "Control" is displayed.

When the screen displayed at this time is not the parameter desired to be set, in this example, the edit screen for pressure depth, the mower button C6 is pressed several times so that the edit screen for pressure depth is displayed. FIG. 6 shows a state in which an edit screen regarding pressure depth is displayed, and indicates that the pressure depth value of track number 1 (TR1) is 64. The cursor is located at the value of the pressure depth, and the value can be increased or decreased by operating the up button C4 or the down button C5 here.

When the edit screen relating to the parameter desired to be set is displayed, the parameter displayed on the edit screen is assigned to the desired display area of the user main screen and stored in the corresponding storage area of the RAM 6. For this allocation and storage, the write button C2 is pressed, and then the buttons B1 to B8 are pressed.
Select the display area to be assigned with. For example, in order to assign the parameters related to the pressure depth displayed on the edit screen to the display area A5, the write button C2 and the button B5 may be sequentially pressed.

By the above operation, when the parameters relating to the pressure depth are assigned to the display area A5 of the user main screen and stored in the corresponding storage area set in the RAM 6, the stored parameters are displayed.
The user main screen assigned to No. 5 as shown in FIG. 7 is displayed. It is not necessary to directly display the contents of the edit screen on this user main screen, and a display program may be set in advance so that the contents are displayed in a simplified manner. Sufficient information can be displayed even in the area. In the illustrated example, “Pressure Depth” is simplified and displayed as “Press Dep”.

Further, when it is desired to allocate other parameters to other display areas on the user main screen, the screen switching button C1 is pressed to display the default screen again, and further the edit switch 38 is pressed to press the edit switch 38 as shown in FIG. It is sufficient to display the edit menu screen as shown in and repeat the above operation. In the above, an example of selecting "Control" and assigning parameters related to pressure depth has been described. However, for example, when assigning parameters on the pitch envelope edit screen, the edit menu screen as shown in Fig. 5 is used. If the button B2 is pressed to select "DCO", and if necessary, the more button C6 is operated to bring up the pitch envelope edit screen, and then the same operation as the above-described operation for parameter allocation regarding pressure depth is performed. Good.

In order to change the parameters displayed on the user main screen, the buttons B1 to B8 at the positions corresponding to the parameters to be changed are pressed while the user main screen is displayed. This operation moves the edit cursor to the position of the parameter you want to change. For example, when the button B5 is pressed, a state in which the cursor 39 is moved to the position of the pressure depth value is displayed as shown in FIG. By operating the up button C4 or the down button C5 in this state, the value of the pressure depth can be increased or decreased. Of course, the parameters stored in the RAM 6 are also changed in accordance with this change.

The parameters assigned to the user main screen can be deleted. When deleting a parameter, in the state where the user main screen is displayed, after pressing the delete button C3, the display area A in which the parameter to be deleted is assigned
Buttons B1 to B8 corresponding to 1 to A8 are pressed. By this operation, the parameter displayed in the corresponding display area is erased and the parameter stored in the corresponding area of the RAM 6 is deleted.
