Emu XL-7 & MP-7 User's Group

Has anyone found out exactly what the fire wire connection on the 
back of the MP/XL-7 is for? I was told by the salesman at the store 
that it could hook directly up to my computer, but how? What I mean 
is is there a program or interface to use it with. I'm running 
everything from Cakewalk 7.0 up to Sonar, Cusbas VST 24 Sound Forge 
4.5 and others and can't figure it out. The manual makes no mention 
of it at all. Help please! Technology going to waste. Donpoppie
