Overview
M-input x N-output mixer
Discussion
The mixer module takes multiple input signals, and "mixes" them down to provide one or more output signals
...
When the module is bypassed, it copies the ith input channel to the ith output channel. If the module has more output channels than input channels, the remaining output channels are set to 0.
