Ok, I did some Googling and I got this to work in my own project without too much trouble. What I did was clicked 'Options' in the Environment window and chose 'Import Environment -> Layer...' then chose the downloaded talkback-B Logic File. This got the Talkback Layer into my project. At this point when I hit the button it was muting my Master Volume Channel, so I clicked and held on the second arrow down coming out of the right side of the 'To Cue Aux' Monitor Box until that wire unplugged. I then Option+Clicked on that arrow and chose the channel I wanted dimmed when the Talkback is on. Then I did the same thing on the bottom monitor box, but this time I chose the channel I wanted muted when the talkback system is off. The only thing that I have a problem with now is that I do not know how to assign a midi controller key to turn this on and off. The button in the environment window is theoretically good, but the problem is that if you click on any channel strip in the mixer it changes what is being displayed in the environment window and the ON/OFF button goes away, so if someone can please offer some help on the Midi Control for this it would be great. I am going to Google some stuff and if I find anything I will post about it.
