There are provided k operators to be used for performing parameter setting. A channel strip screen displays a plurality of parameters for each of selected k channels. In response to selection operation to select a desired one of the parameters displayed on the channel strip screen, a parameter window related to the selected parameter is opened on a display. The parameter window displays, for each of selected k channels, a parameter of a same type as the selected parameter. Each of the parameters displayed for the selected k channels is assignable to any one of the k operators. When selection operation to select any desired one of first-type parameters has been performed, the parameter window is opened immediately, but, when selection operation to select any desired one of second-type parameters while the desired second-type parameter is in a non-selected state, the selected desired second-type parameter is set to a selected state without the parameter window being opened and then the parameter window is opened in response to further selection operation of said desired second-type parameter having been set to the selected state. When the second-type parameters are set in the selected state with the parameter window not opened, each of the second-type operators in the selected state, displayed on the channel strip screen, is assigned to any one of the k operators. |
