Do a search. It's been covered pretty extensively in the past. Yes, it can be done.

Actually, I've yet to find anyone's suggestion that works like a Freeze pedal, includes Yeks. I own a Freeze- clean tone in, clean held note out, works immediately without needing to slowly sweep into it. If the Axe-FX can accurately do what an EHX Freeze does, I haven't seen anyone do it yet.
Keep looking then. I've heard the clips of the Axe-FX doing it, but I'm not inclined to go dig them up. The pedal never interested me all that much...

in my version you just rock a controller back and forth to capture whatever's playing. i don't think it works in the same way the freeze does, but then again i don't know how the freeze actually works. personally, i think mine sounds nicer, but then i've only heard crummy youtube demos of the ehx.
I've looked The closest I've heard was one by JavaJunkie that didn't have the simplest interface and seemed to still have a bit of a delay effect on the held note. To get it to do what the Freeze does, you'd need to have a clean tone in, clean held note, and clean tone to play over the held note, along with a simple interface for changing held notes quickly. If the pedal never interested you much, you might not know how differently it works/sounds than what's been done with the Axe.
Dangit! I forgot my ears only worked when I was considering buying a pedal. I'm not capable of critical listening under any other circumstances, or at least my conclusions can't be trusted...
Nevertheless, I like some of the Axe clips better than the ones I've heard from the Freeze. It's a cool idea, but I don't really need it for my playing needs. If I did, I'd get the sound in the Axe-FX before I would buy that pedal.
