I'm currently using the un-weighted Roland A-800Pro, which has a 'controller/surface' profile set up in Sonar. I'm not sure the Arturia has this for Sonar...or vice-versa.
Support for APro is not just a 'profile', it is a separate program (plug-in) written for that particular controller. Arturia has no such plug-in. Using "Generic" plug-ins (you will most probably need both, see chapter 40 in the SONAR reference guide) you can get it work more or less ok. But it will take some time to (understand how to and ) configure the board and plug-ins. The integration level still is not going to be on A-Pro level (ACT MIDI support 9 buttons, 8 sliders and 8 encoders, Generic Surface support 12 ACT parameters only and it does not work with buses, you can imagine that even combination is going to be full of compromises with 9 sliders / 10 encoders board).
There is my alternative to that plug-ins. With some patience you can make a preset which will work with Arturia on the same (or better) integration level as APro. But so far, no one had that patience even with smaller boards
