Anybody have a clue how to get the Aria player with GPO 4 to work with Garageband 10.1.2?  Every tutorial I'm finding addresses older versions of Garageband.

I've updated to the latest Aria engine and player as of this morning.  I even found a little tutorial having my download a specific package for GPO for Garageband and although I can see the list in Garageband, it does nothing (presumably because I can't find a way to "attach" the Aria player in this version of Garageband.).
