How many controllers can Live utilize simultaneously?

I saw in a Novation video (or read it somewhere-forget which) that up to six Launchpads can be used with Live. Is this strictly for the launchpad or is six the general amount of controllers Live can run at one time?
I could have sworn I read threads where some users have more than six controllers that can run simultaneously. Just double checking.

I think it's only 6 for the dedicated controllers. so stuff you can select from the drop down menus. Otherwise i'm pretty sure it's unlimited (midi limitations)

Ah ok. So I can view up to six control surfaces but can utilize as many as I want for mapping to parameters, obviously setting each accordingly so there's no conflict. Cool, thanks.
