I am trying to load a midi controller to control a media player in a song, but even though the media player is present the only options I get in the drop down menu (Input Ports section) are the soft synths present and not the media player?
If I and the others who posted understand correctly you are trying to send a midi controller command from the keyboard controller (a physical switch) to a media player loaded in a song. First, the media players never appear in the input ports section, on the routing page you will see the racks and plugs and media players. ( in this example media player 1)
