Abstract: As preset component data to perform processing on components for signal processing in a mixer engine, data for PC and data for transfer to be transferred to the mixer engine to cause the engine to perform signal processing are stored on the PC side, and data for engine is stored on the mixer engine side. When being directed to upgrade the preset component data on the mixer engine side, the PC compares the ID of each component included in the data for PC stored in the PC with the ID of each component included in the data for engine stored in the mixer engine, and, when detecting an ID existing only in the former, transfers the aforementioned data for transfer on the component corresponding to the ID to the mixer engine and causes the engine to store the data as the data for engine.

Abstract: A digital mixer has a custom component specified by a configuration ID. Further, the same configuration ID is provided to another custom component for ensuring compatibility of scene data which is used for operating the custom component. When a custom component of the mixer configuration is edited, the edited custom component is provided with the same configuration ID as the initial custom component before the editing. Scene data of the initial custom component can be copied to scene data of the edited custom component or vice versa provided that their configuration IDs match with each other.

The edited mixer configuration is written back to the storage. The storage may store a protected mixer configuration created and supplied by a vendor, such that the mixer configuration created by the vendor is protected with a vendor authority higher than the user authority with which the user is able to log on the mixer engine control program.
