I read through the directions on the a-112 sample dump program. It says you need to have 
MIDI In/Out, going from your PC to the a-112. I have an Intel MacBook(Laptop), that runs 
Windows XP flawlessly using a program called Parallels Desktop. I have a MOTU MIDI Express 
Interface. It connects to the computer via USB. Will this work? Will the a-112 communicate 
through a MIDI interface or does it have to be plugged directly into the MIDI ports on a PC 
Soundcard? Excuse me, I know next to nothing about Windows computers.
