Sonar Cross-grade question: How do I set up my A300-Pro controller in Studio One 3?

I bought a Fader Port 8 to use with Sonar but I have just found out that Sonar is no longer supported so I thought that I would try to lea Studio One. However, when I tried to get my A300-Pro controller (which I use as the keyboard for soft synths) linked to the Studio One software, nothing happened. Has anyone else successfully completed this set up?

Cheers,

Ian
