Overview
A smoothed mixer module with M outputs and N inputs
Discussion
This implements the same functionality as MultiChannelMixerSmoothed module, but is significantly more efficient, both in speed and memory.
...
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.
