The demux object has a single input audio buffer and several output buffers. Based on a tuning variable, it selects
the output where the input should be sent. Only one of the demux objects’ output channels will have data at any
one time.
The number of output channels is configurable in the SFD.
The demux object always has one variable accessible by the GTT and that is the variable that selects the output
channel where the input should be written.
This module does not have any exposure to control.
