The USB port can be used to transfer Patterns via E-Loader, but that is it
at this time.
I agree, we need a better option for backing up Presets than just MIDI
dumps, too long to do, and impossible to organize that way. Especially
since there's no removable media onboard :)

change
in a new OS, what you need is a Midi Connection to use MIDI Dumb.
