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.
