I figured it out so for anyone looking for a solution…
First go to IAC Driver located in audio midi setup then tap on window the show midi studio. From there tap on IAC Driver (internal application control) add a new port then make sure the device is online box is checked.
After you have successfully created an IAC driver go to one of your songs in stage Traxx go to edit lyrics and scroll all the way down on a new line and create program change.
[midi: CONTINUE, PC1@1]
My program changes were one off, so in stage Traxx it I typed PC1 but in MainStage it transmitted to PC2. If this is not the case in your situation download MIDI monitor to make sure you set the right PC in MainStage.
Ok so one you have that sorted out head on over to MainStage click on the patch you want to map (make sure you are in edit mode. Go to patch settings the. Attributes and where it says program change set the PC# to whatever it is transmitting on.
Repeat for every patch in MainStage and stage Traxx. I know this is time consuming but once it’s done you don’t have to worry about MainStage it will control it remotely with stage Traxx.
I’m terrible at explaining so let me know if you have any questions
