I've never noticed any weird stuff going on when I have used the Crestron trigger codes but then again I keep it pretty simple, button setup to do a progress bar page flip (8 pages) with the trigger code on it.
I set the button to stand alone mode with the trigger code on it and then in the macro do the page flips etc.

I do recall reading something about the amount of sustains being set to 4 or similar that makes them more reliable.
