Yamaha DTXpress/DTXplorer/DTXtreme

I found this application and was wondering if anyone has tried using
it. It's called SysEx Librarian: http://www.snoize.com/SysExLibrarian/

Will this work with the SysEx libraries in the Files section here? I
would really like to use that Ringo kit with my DTXII. I have Cubase
and Garagaband, but little experince using MIDI at all. Are there any
Mac MIDI users out there?

Doing a Google search for OS X and SysEx reveals little to no
information on it. Is this even possible?

Thanks,
Jay
