Just start AN1X Edit, in the top menu, click the setup item, then click the Midi Port Setup item.
This will open a small dialog where you can select the Midi in and midi out port.
Just select the entry corresponding to the midi interface connected to your AN1X for both midi in and midi out and you should be good to go.
