I'm sorry but I fail to guess what you mean with "unquantize" ...
The most you may have, before committing to life, is that you may always "Undo" any specific move or change. But for the sake of heart, it cannot guess what original the "unquantized" material was, unless you saved or backed it up as wisely as you should, ever. ;)
If what you really want is to preserve your original performance for good, then make sure to save it into a safe place as soon you make it, read session name and archive (save as .qtz as baseline, perhaps? just a hint, you're not really obliged to follow this hint)
