Now that I've had my DC2A all of a week (!) I'm thinking it would be 
cool to be able to play MIDI files stored on my laptop wirelessly to my 
DC2A.  Is that possible?  Would this device work?

Would I be able to "send" a MID or FIL file from my laptop to the 
DC2A?  How would it begin to play?  Does the external device (the 
laptop) show up as a channel like the Fd, CD, 1, 2, 3, etc. channels on 
the control unit?  Do I also need particular software to make this work?
