All I know is it is the version of Pro Tools that comes with the "Pro Tools 9 + Mbox Mini" package (see also here).
Kinda sounds like you can use any interface with it (or no interface, which I assume means soundcard), but some confirmation from someone with direct experience would be awesome!
any, do you mean any of the interfaces on the mbox? or any connected to the computer? FWIW, I have used previous versions of ProTools without dedicated hardware... just the computer's built-in interfaces. – JoshP Jun 20 '12 at 15:42
