Reset them. If you want, get anixedit or just any MIDI program that can do a system dump, if you want to keep them just in case, but really...what's the point?
I mean, you say they are dull, so I don't really get why you are even thinking twice about it...
IF the presets were just as dull or duller you still would have to either make your own or sell the thing (and I assume you bought this because you know it can get some good sounds)
If they are better (pretty certain they are) then you win, but if they are still not what you really want you gotta program some right?
reset it!
