Patent attributes
A digital mixer has a processor capable of executing a program to constitute an audio signal processing unit corresponding to various mixer configurations. Configuration ID is attached to each mixer configuration, and the same configuration ID is attached to the mixer configurations having compatibility between their scene data which is a data set of parameters for use in operation of the audio signal processing unit. When a mixer configuration is edited, the same configuration ID as that of the mixer configuration before editing is attached to the mixer configuration after editing. Under the condition that there is a match between the configuration ID of read source and the configuration ID of write destination, the scene data accompanying each mixer configuration is written from the mixer configuration of read source to the mixer configuration of write destination.
