As far as I know, Studio One and Sonar are the only major DAWs that have full ARA integration with Melodyne.
To get the benefit of full ARA integration with Sonar, you should insert it as a "region effect", not in the effects bin.
Very cool. I had to go and read up on what this actually meant. Apparently, there's been some nice work being done to make things easier and faster.
I doubt that the full ARA integration thing will work for me as I still operate on X1.... but it's nice to see they aren't setting on their proverbial hands while time marches on.
