Yamaha DTXpress/DTXplorer/DTXtreme

Hi Folks,
I was wondering if anyone knew of a DTXpress III compatible editor /
librarian, preferably something that runs on the mac or java.  I'm
basically looking to organize my user kits and extract all MIDI data
from the brain so I can map software samplers easier on my laptop. 
I've got a PC too, so I'm open to a PC solution also if there's one
available.

Thanks in advance for any insight on this!
