Audio mixer group fader graphical user interface

A non-transitory computer readable storage medium storing a group of instructions for causing a computer of a mixer apparatus to perform a fader operation processing procedure, said mixer apparatus including manually-operable and automatically-driveable physical fader operators provided in corresponding relation to a plurality of channels, wherein a plurality of desired physical fader operators of said fader operators are capable of being grouped into one of a plurality of groups and said physical fader operators in each of the groups are operable collectively in an interlocked fashion, said processing procedure comprising:

• a step of opening, on a screen of a display device, a window of a given one of the groups in response to selection operation by a user and displaying, on the window, individual operator images indicative of individual settings of individual ones of said fader operators belonging to the given group and a group-master operator image for the given group;
• and
• a step of changing a display of the operator images in such a manner that settings of the individual operator images belonging to the given group, displayed on the window of the given window, are changed at a rate or by an amount corresponding to operation by the user of the group-master operator image, and automatically driving the individual fader operators belonging to the group collectively in an interlocked fashion at a rate or by an amount corresponding to the operation by the user of the group-master operator image to thereby change the settings of the individual fader operators.
