I don't have a Micron, but I have a couple other pieces of MIDI gear. You're going to need to use the MIDI In/Out of the Micron to a MIDI In/Out on your computer. Whatever the software you use to edit presets or even just load the SysEx files will use the MIDI interface to communicate with the Micron.
If you don't have MIDI In/Out of your computer you could always try one of
these ...
