Patent ID: 8849436

Claim:
A system including at least one controller device connectable to a computer where a mixer function is implemented by application software, each said controller device comprising: a communication interface connectable to the computer; a plurality of faders each capable of remote-controlling a parameter of one of a plurality of channels assigned thereto, the plurality of channels having consecutive channel numbers; a channel shift button operable to give an instruction for collectively shifting, by one channel, the channels assigned to the plurality of faders; and a bank shift button operable to give an instruction for collectively shifting, by one bank, the channels assigned to the plurality of faders, the one bank comprising a number of channels equal to a total number of the plurality of faders, said system comprising a control section which, upon activation of the application software, assigns channels, which are to be mixed by a mixer function, to the plurality of faders in ascending order of channel numbers starting with a predetermined first channel number, and which collectively shifts, by one channel, the channels assigned to the plurality of faders in response to the instruction given via the channel shift button or collectively shifts, by the one bank, the channels assigned to the plurality of faders in response to the instruction given via the bank shift button, wherein, when a plurality of the controller devices are connected to the computer, said control section not only assigns the channels to the faders, considering that a single controller device provided with a given number of faders, equal to a product between a total number of the controller devices connected to the computer and a total number of the faders provided in each of the controller devices, is connected to the computer, but also stores controller information including respective identification information of the controller devices connected to the computer and information indicative of a predetermined first channel of all of the channels assigned to the faders.
