Hi Mauricio, there are some things that would be possible but full integration is unlikely I'd expect. It's too hard for Cake/Roland to get this great controller fully integrated to X2 so one can only imagine the drama trying to get it to work with a platform it wasn't designed for....oh hang on, that probably includes X2. 
In a less tongue in cheek vein, if only we could get flexible integration, we would ALL be jumping with joy so you have to think it's not possible or they simply would have done it to shut up all the moaning. Either that or they really are dumping support....? Sounds like you may be jumping of the good ship Sonar? Cheers.
Cakewalk and Roland was not speaking the same language when they jumped into the VS-700 project... I am glad to be able to sell my set, I tought it was barely impossible to do it without have a huge money lost, but God is good, and I got almost 5k back. Since I paid 6k 4 years ago, it's a incredible deal, isn't it?
Anyway, I will keep Sonar under my hood, but I am getting more and more satisfied with Reaper. Such a nice well developed software.
So, today I have Sonar X2a, Reaper 4.402, Reason 7, Cubase 6.5 and ProTools 10. (Reaper have a ProTools theme, is very funny to use it)
Still, I like Sonar.
God bless you all
