Hi, I'm using a FireStudio Project (FSP) with Reaper and have had this issues - pan not working. Make sure that Presonus Univeral control (UA) is set up correctly - open it up and check the pan and levels. If nothing in UA is wonky, try opening a new reaper project (without any templates etc.) and check if it's working there. I've had success just copying the items to a new project - but don't actually know whats been going wrong with the panning/stereo (other than not working as expected).
Out of curiosity and not related to this - what latency are getting with the FSP?
