This is only for the Bus 1 to recognize delay compensation, it doesn't have anything with the sound.

Create a mono Aux input, with your sidechain bus as an input (Bus 1), and with your Master bus as an output (Bus 11-12). If you want your sidechain to be in time with your delay compensation, you have to implement it in your Master bus routing, in order to know what delay compensation to use. All other guys with other DAWs don't have that problem at the start, because they already have a 'Master bus', but in Pro Tools you have to make it. In that way, Pro Tools starts to calculate delay compensation in a proper way. Let's say that you put Bus 11-12 as an input of that Aux Input, and you send all your tracks to that Bus. In order for Pro Tools to properly calculate delay compensation, first you have to send all your tracks to one stereo Aux Input, which would be your 'Master bus'.
