Smartav Tango 2 & cubase

Hello.
I’m a Nuendo 8.3 user and I’m working with Avid Artist Mix & Control on a PC windows 7 64bits.
I know that Nuendo is not Cubase but I think there are similarities between them.

I have the oportunity to buy a used Smartav Tango 2.

how does the smartav tango behave with Cubase?
does the tango work well with the new fonctions ofcubas?

Sometimes I mix movies that need more than 100 tracks, will the tango follow?

Do you know if the use with the artist mix at the same time can be problematic?

A big thank you in advance for your responses.
