Abstract: Arrangements are made such that a plurality of operators, such as faders, can be set to opposite operational directions. When any one of the operators has been operated in a particular direction, a control value of each of the other operator, set to the same operational direction as the operated operator, is controlled in the same direction as the particular operated direction, while a control value of each of the other operators, set to the opposite operational direction from the operated operator, is controlled in the opposite direction from the particular operated direction. Where control values of a plurality of channels are to be controlled via a collective control controller, each of the channels is set to a forward or inverse operational direction. Thus, even faders that are to be operated in opposite directions can be appropriately operated collectively as a group.

Abstract: Scene data including a set of values of a plurality of signal processing parameters are stored in a memory. Adjusting values (offset values) of the parameters stored in a buffer are each modified only when a user has performed operation for modifying the value, and never modified automatically. Upon selection of new scene data, the individual parameters of the new scene data are read out from the memory, and the value of at least one of the read-out parameters is modified in accordance with the adjusting value. The values of the parameters, including the thus-modified value of the parameter, are collectively set in a signal processor, such as a mixer. If the modified parameter value is beyond a predetermined limit value, a value corresponding to the limit value is set in the processor, in which case the adjusting value stored in the buffer is not changed.
