Patent ID: 7738980

Claim:
An apparatus for editing mixer configuration data describing a mixer configuration to be executed by a digital mixer comprising a sound signal processing unit capable of executing a program and said mixer configuration composed of various components including one or more custom components each specified by a component identification code and a version code, the apparatus comprising: a first storage that stores custom component data which describe configuration of the custom components, including a first custom component and a second custom component; a creating section that creates a new custom component data of a new identification code and an initial version code and writes the created custom component data into the first storage; a first editing section that edits contents of the custom component data stored in the first storage, the component identification code of the custom component data is unchanged by the editing while the version code is updated by the editing; a second storage that stores first custom component scene data which is a data set of parameters for use in operation of the first custom component specified by a first component identification code and a first version code; a second editing section that edits contents of the first custom component scene data stored in the first storage section; a third storage that stores second custom component scene data which is a data set of parameters for use in operation of the second custom component specified by a second component identification code and a second version code; and a copy section that, in response to a copy operation by a user, confirms whether or not the first component identification code and the second component identification code match with each other, and only when the confirmation is affirmative even though the first version code and the second version code are different, reads the second custom component scene data from the second storage section and writes at least a common part of the read second custom component scene data into the first storage section, where the common part corresponds to a common portion of the first custom component and the second custom component.
