Abstract:
1. A digital mixer including a display, a plurality of cursor controls, an increase/decrease control, and a plurality of channel strips for controlling parameters, including an input signal level, of each of a plurality of input channels associated therewith, on a control panel, said channel strips each having a level setting control and a selection switch, said digital mixer comprising: a view selector for selecting one of a plurality of parameter views and displaying the selected parameter view on said display, said parameter views each corresponding to one of the parameters and showing a corresponding parameter for each of the plurality of input channels; a cursor controller for detecting a user operation of at least one of said plurality of cursor controls and positioning a cursor at one of the parameters shown in the selected parameter view; a level controller for detecting a user operation of said level setting control of one of said channel strips and controlling said input signal level for an input channel corresponding to the channel strip in accordance with the operation of said level setting control; a channel selector for detecting a user operation of said selection switch of one of said channel strips and positioning, in the selected parameter view, the cursor at one parameter for an input channel corresponding to the channel strip among the parameters for plural input channels; an assignor for selecting a parameter among the parameters of the input channel to be assigned to said increase/decrease control; and a parameter controller for detecting a user operation of said increase/decrease control, judging whether or not said selection switch of any one of said channel strips is operated at the same time while the operation of said increase/decrease control is detected, and when judging that no selection switch is operated at the same time, changing a value of the parameter corresponding to position of the cursor in the selected parameter view, in accordance with the operation of said increase/decrease control, and, when judging that said selection switch of a channel strip is being operated at the same time, changing a value of the parameter selected by said assignor among said parameters of an input channel corresponding to the channel strip in accordance with the operation of said increase/decrease control.
