Claim:
A digital mixer apparatus including a plurality of input channels and arranged to mix signals processed in individual ones of the input channels, said digital mixer apparatus comprising: a monitor section that outputs, for a monitoring purpose, the signals of one or more input channels selected, in response to a monitor channel selecting operation by a user, from among of the plurality of input channels; a plurality of effecters; an effecter insertion setting section that, in response to an insertion operation performed by the user for each of the plurality of effecters, inserts the effecter into an input channel designated by the insertion operation, from among the plurality of input channels, so that the inserted effecter imparts an effect to a signal being processed in the designated input channel in accordance with parameters of the inserted effecter; an editing section that displays on a display a parameter editing screen for an effecter selected, in response to an effecter selecting operation by the user, from among the plurality of effecters, and edits one or more of the parameters of the selected effecter on the parameter editing screen, in response to an editing operation by the user; a mode setting section that sets either an interlock mode that permits interlocked operation of one of the effecters and monitoring of the one or more input channels into which the effecter is inserted or a non-interlock mode that prevents interlocked operation of the effecter and the monitoring of the one or more input channels; and an interlock control section that, when one of the effecters has been selected via said editing section in response to the effecter selecting operation by the user, controls said monitor section to automatically select an input channel into which the selected effecter is inserted, and output, for monitoring purpose, a signal of the selected input channel if said digital mixer is in the interlock mode.
