After doing a heck of a lot of searching, I found a potential issue with the script.

Someone had this issue with a different controller and said they just added this code to the script:

self._device_selection_follows_track_selection = True

Now, I’m trying to open the files so that I can add it, but it’s not appearing as syntax but computer gibberish…
