There is no controller that can map Sonar, because of ACT, and the way it works, you actually have to map Sonar to your controller by using ACT and having Sonar 'listen' to your controller (or map the whole thing manually - increasing your chances of developing carpel tunnel).
There are only 2 controllers on the market that can map themselves to DAW software, that is the Axiom Pro and the Novation SL MKII, neither of these will map themselves automatically with Sonar as you still have to use ACT, which is a pain in the ass.
There are some presets in ACT, but these give very limited functionality without the user
fully understanding ACT and doing quite a lot of work, again a PITA.
By all accounts the best controllers to use with Sonar are Edirol and the new Cakewalk controllers, because Cakewalk and Edirol are owned by Roland they have done the best job of integrating these controllers into the clumsy and out of date ACT plug in.
Unlike the manufacturers of Pro Tools, Cubase, Logic, Ableton etc. who have all started to work with hardware manufacturers and each other to integrate their software and controllers very deeply, Cakewalk is keeping it's self distanced and isolated for the sake of what I don't really know (controller sales)?
