Abstract

When a name of a group level control section is tapped, the group level control section is expanded and a group expansion screen is displayed on a display. In the group expansion screen, the group level control section is expanded and images of channel level control sections for respectively controlling output levels of channels belonging to a group corresponded to the group level control section are displayed by juxtaposing next to the group level control section. In this case, each channel level control section belongs to a lower layer than that of the group level control section. Although the channel level control sections and the group level control section belong to the different layers, they are aligned in the same line on the same screen on the display.
