When the key 12-2 is operated, the PGM # changes according to the operation, and the tone assigned to the displayed PGM # becomes the tone assigned to the eighteenth part. At this time, the musical instrument type assigned to the set PGM # is graphically displayed.

In FIG. 3, since the generated tone levels of the 01st to 16th parts are all "0",
This is the case where no sound generation instruction is received from the sequencer 1 or the keyboard 2 or the volume parameters of the 01st to 16th parts are all set to “0”. In FIG. 4, the volume parameters of the 17th part to the 32nd part are respectively set, and the current 17th part to the 3rd part when the sounding instruction is received from the sequencer 1 or the keyboard 2 is set.
The music sound levels of two parts are displayed. To change the setting of the volume parameter, the cursor key 12-3 is operated so as to move the cursor to the VOL (volume) parameter position among the parameters shown below, and then the +/- VALUE key 12-4. May be set to a desired parameter amount. Other parameters can be set in a similar manner.

For example, FIG. 5 shows a display mode in which the cursor key 12-3 is operated to match the reverb send parameter (REV). FIG. 5 shows a state in which the part “18” is selected, and since the cursor is set to the reverb send parameter, “Rev Send = 10” is selected.

The reverb send amount of the ~ 32nd part is displayed. The displayed “100” is the reverb send amount of the selected 18th part, and the portion where the reverb send amount “100” of the 18th part is graphically displayed in a bar graph blinks.

In this case, the VALUE key 12-4
Is operated, the reverb send amount is set to “10” according to the operation.
"0". In this way, the reverb send amount can be set for each part.
When a parameter other than the reverb send parameter is set, the display mode is set to a display mode in which the parameter can be set by moving the cursor to the parameter. As described above, the parameter display of the first part, the tone name of the selected part, and the like are displayed separately in the left half and the right half, and the parts 01 to 16 and the parts 17 to 32 are displayed separately. Displaying on the LCD 13 with the display arrangement reversed is the first aspect of the present invention.
As an example, in the display mode of the first example, only one parameter of the 01th part to the 16th part or the 17th part to the 32nd part can be displayed on one display screen. To solve this, a second embodiment in which the display mode is changed each time the DISPLAY key 12-1 is operated will be described.

FIG. 6 shows a display screen when the DISPLAY key 12-1 is operated once in the state of the display screen shown in FIG. In this figure, the reverb send amounts of all the parts from the first part to the thirty-second part are displayed elongated in the center of the display area. For this reason, the reverb send amount is displayed on a half scale and a half size. In addition, the DISPLAY key 12
When -1 is operated again, the display screen shown in FIG. 7 is displayed.
In this display screen, “Rev Send = 100”
Is omitted, but the reverb send amount is displayed in full scale, so that the size can be clearly understood. When the DISPLAY key 12-1 is further operated, the display screen shown in FIG.
The display mode of the display screen shown in FIG. 7 is cyclically displayed each time the DISPLAY key 12-1 is operated.

Next, the display processing will be described with reference to the flowchart of the display processing routine of the CPU 9 shown in FIG. 8 for executing the processing for displaying information on the LCD 13 described above. When the display processing routine is started, it is determined in step S10 whether or not the part selection switch (PART key 12-2) has been operated. If it is determined that the part selection switch has been operated, the operated part selection switch is turned to the 01st part. To the sixteenth
It is determined in step S20 whether or not the part belongs. Then, the part selection switches are switched from the 01st part to the 1st part.
If it is determined that the part belongs to the sixth part, the parameters of the selected part are displayed on the right in step S30. If it is determined that the part selection switch does not belong to the 01st to 16th parts, the parameter is selected. The parameters of the part that was selected are displayed on the left.

Next, as in the case where it is determined in step S10 that the part selection switch has not been operated,
Proceeding to step S50, the display mode switch (DI
It is determined whether the SPLAY key 12-1) has been operated.
If it is determined that the operation has been performed, the content of the register ST is incremented by one in step S60, but if the content is "2", the content is returned to "0". If the register ST = 1 in step S70, the parameter values of the parameters of all parts are compressed and displayed, and the parameters of the selected part are displayed as shown in FIG. In the case of 2, the parameter values of the parameters of all parts are displayed at full scale as shown in FIG. 7, and when ST = 0, the screen returns to the original and the screen shown in FIG. 5 is displayed. Then, the display processing routine ends as in the case where it is determined that the display mode switch has not been operated in step S50.
