Simple microkorg question for a newbie.

[cemego]

I see all sorts of people offering microkorg presets and some sound great.

Question is:

When i implement these, do i lose the factory ones forever because there are some factory presets i could never live without.

Please let me know.

(I have this paranoia from when I firmware upgraded my Electribe Sampler and lost a lot of stuff so I'm a-scared.)
