Stopping from development doesn't mean suddenly ARA support in it stops working though. It's sad to see Gibson killing yet another DAW, even if I don't use it (I did use Sonar 7 many moons ago).
However, Reaper will be getting ARA support, it has been hinted by the devs, very soon from what it looks like. (And I'm a Reaper user, ehehe.)
So yes, definitely do try and invest some time in doing this, if at all possible! 🙂
