Is anyone using Rapidchange ATC in Mach 4 v 5036

I've never seen something like that.  I just watched some YouTube videos on it.  Looks simple enough to implement into Mach4. 
It just requires some scripting.  Personally I would use #Vars for each X & Y pocket position and call those up depending on the tool requested. 

I have not watched all of this.  I just found it and I'm posting it here.
I would make my script from scratch and make it work how I want.......
But nonetheless here is a video I found with Mach4.
