I'm having trouble getting my FD-8 and Logic Fun synched up.

I'm running Logic Fun on a Mac with Midiman Midisport 2x2 interface. I have no problems synching the FD-8 to hardware instruments and sequencers, but when I hook it up to the Mac nothing happens. I'm pretty new to MIDI synching so I might have overlooked something. Any suggestions on how to set up the FD-8 and the Logic Fun software would be greatly appreciated. Thanx in advance
