Abstract:
1. A digital mixer including a plurality of output channels, a plurality of output ports and an output patch section, said digital mixer comprising: a storage section which stores a plurality of parameters including first parameters of individual ones of the output channels, second parameters of the output patch section and third parameters of individual ones of the output ports; a connection change section which changes one of the second parameters, stored in said storage section, in response to connection change operation by a human operator; a plurality of n controls; an output channel selection section which, in response to output channel selection operation by a human operator, selects one of the plurality of output channels; a parameter allocation section which, once one of the output channels is selected by said output channel selection section, detects one or more said output ports connected to the selected one output channel on the basis of the second parameters, and allocates one or more said third parameters, of the detected one or more output ports to one or more of the n controls; a parameter change section which, in response to operation by a human operator of one of the n controls, changes a value of the third parameter allocated to the one control by said parameter allocation section from among the plurality of parameters stored in said storage section; said plurality of output channels, each of which receives a supplied audio signal as input, controls a characteristic of the channel-received audio signal on the basis of one of the first parameters stored in said storage section and outputs the channel-controlled audio signal; said output patch section which, in accordance with connections between said plurality of output channels and said plurality of output ports indicated by the second parameters stored in said storage section, supplies an audio signal, outputted from each of the output channels, to one or more said output ports connected with the respective output channel; and said plurality of output ports, each of which receives an audio signal supplied by the output patch section, controls a characteristic of the port-received audio signal on the basis of one of the third parameters stored in said storage section and outputs the port-controlled audio signal to outside the mixer.
