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.

Apparatus for editing configuration data of digital mixer

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.

Editing apparatus of scene data for digital mixer

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.

Component data managing method

In a mixer system including: a plurality of mixer engines each provided with a programmable DSP; and a PC controlling operations of the respective mixer engines, the PC stores, as zone data, a plurality of configuration data each indicating a configuration of signal processing to be executed by one mixer engine or more out of the mixer engines under the control of the PC, accepts the selection of the zone data, and when the necessary mixer engines are in a controllable state, transfers data on a part of the aforesaid configuration which is to be assigned to each of the mixer engines, to the corresponding mixer engines. Then, when the selection of the configuration is accepted, each of the mixer engines to which the configuration is transferred is caused to execute the audio signal processing according to the selected configuration.

A digital mixer has a processor capable of operating in accordance with a program to constitute a sound signal processing module and executing a program corresponding to mixer configuration data defining a mixer configuration of the sound signal processing module to perform a sound signal processing operation of the mixer configuration. In the digital mixer, a current memory stores an operation data set having a data structure corresponding to the mixer configuration data. A control section controls the sound signal processing operation of the sound signal processing module based on the operation data set stored in the current memory. A storage is provided for storing a plurality of operation data sets and attribute information indicative of data structures of the respective operation data sets. A select section selects one of the operation data sets stored in the storage. A converting section converts the selected operation data set from the data structure indicated by the attribute information of the selected operation data set into a data structure corresponding to the mixer configuration data, and recalls the converted operation data set to the current memory.

A mixer engine control program is executable by a computer for performing a method of displaying and editing a mixer configuration which specifies a mixing process of a signal processing apparatus. Logging on is made to the mixer engine control program with a user authority. Mixer configuration is read from a storage. The read mixer configuration is displayed and edited within a scope permitted by the user authority with which the mixer engine control program has been logged on. 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. When the mixer configuration protected with the vendor authority is supplied, the supplied mixer configuration is protected against displaying and editing of the mixer configuration if the mixer engine control program has been logged on with the user authority.
