I tried it today again, it works good but what is a immersion killer for me: it always assigns a transition on approach. In real life you would get vectors a lot more often. Also it doesn’t control the AI.
VoxAtc is the best! It is the only program which actually separates the traffic, and that what Atc is for!
With all the other programs all the aircraft just fly around like madmen which drank much too much whiskey!
