Depends on what you mean by funky.
If the smell is similar to what you would call "brett funk" in a beer, then i would say you are in the clear. What you dont want is nasty, stank, armpit, horse ass smell. From the accounts Ive heard though, lambic fermentation cellars smell alot like freshly baked sourdough bread. I wouldn't worry about it, because worrying is not going to change it. Let it do its thing, and in the future, you will know if that smell is normal or if it will mess up your beer.
