I'm using the ASIO drivers with Sonar 2.2 XL. Apparently there is an issue with Sonar and ATI's catalyst 3.2's Rage Theater audio (and Sonar's installer with XP SP1), so I went with the ASIO drivers in Cakewalk. Unfortunately, I've not had any time to really check them out, but can report that they "seem" to be working OK. I played along with the session drummer(midi) and tried some effects patches with my guitar as well. Later this week I plan on spending some time on a few tracks I'm working on, so I'll be able to run it through the paces a bit. I'll report back to the thread after.
BTW, I don't know if you're referring to Paul deLay with your sig (local blues giant), but hey...cool if you are

, I always enjoy him at the clubs and the festival now that he's back.
