Voice tracking feature differences across editions?

Hi, I read in a thread something about the ability to use beds and the cartwall and so on in more advanced editions of mAirList, but the buy page doesn’t mention advanced voice tracking anywhere. Could someone please overview the specific differences in the voice tracking feature across different editions of mAirList? I currently have Home Studio, I’m wondering which if any voice track functionality I would gain if I were to hypothetically upgrade at some point.
