Disklavier

Hello, I am trying to get my disklavier to send/receive MIDI, but 
something is not set up right. I am running Micrologic on Macintosh. I 
am using the Midisport 1x1 USB adapter and have the cables set up 
properly ((?)-Midi Out on piano to Midi In on computer and vice versa 
for the other cable). 

Hitting the MIDI button on the piano starts up the "MIDI setup mode" 
but I am not sure what to do from there. The computer doesn't 
recognize any signal in/out of the piano.

Any help would be appreciated. I am completely new to the world of 
MIDI, but can otherwise perform whatever I need to on the computer...

Thanks in advance!
