Hi there! Fantastic software!
I'm using an Xair18 with Mixing Station on iPads with App Link. I also have another software I would like to use on another computer in combination.
This other software selects channels and also sets the RTA source channel (similar to the Follow Source option in Mixing Station).
It would be really cool for Mixing Station (even if it's a pro feature) to listen to changes in the RTA source and change it's selected channel in response.
