Comment 7 for bug 1725178

In our case, "Air Monitor" will add the Talkover mix back to Headphones and Both, which was original removed to avoid Echos/Delay. Is there as use case to short time monitor the air signal with lets say a momentary switch?

> For Mixxx, that would be Main, Headphone and the aux's.

OK, so there is no mixing bus/engine? Just allow to copy Aux1 for example.
What is the use case for listening to a single Aux channel in the booth?
