Welcome to the party

FWIW - Pro Tools support is basically HUI+key commands, but there may be some movement on that front at some point - since I heard AVID (who now owns Euphonix) talking about making the EuCon protocol available to other console vendors to add Pro Tools support. That was a year ago at a Cubase 5 demo at ToddAO, so we'll see if that ever comes to pass.
As for Cubase 6 - I saw a really neat new feature where the 8 Quick Controls were auto-mapped into tracks, and then those auto-mapped QCs showed up automatically on the Tango. That meant that Instrument tracks where you have Native Instruments' "Massive" instantiated, the Macro Controls on the plugin get auto-mapped into the QCs, and therefore they show up immediately on the Tango console.
It's really slick and really useful.
