Mixer
Mixer objects allow access to Mixer components that have been named in the design. To create a mixer object, call Mixer.New( mixerName ). The mixer object uses a string specification to determine which inputs and outputs to apply changes to. The syntax supports either space or comma separated numbers, ranges of numbers or all (*). It supports negation of selection with the '!' operator.
