You've probably figured this out by now but I just got one of these so I thought I'd post for anyone else trying to figure it out.

For Output choose MIDIOUT2(SAMSON Graphite 49). I've got my Graphite 49 set to the Audition preset as I use that software as well and it works fine, you can use the Bank button to skip across nine faders. Its well documented here:
