Same problem
I'm having the exact same problem. I'm on a Mac, using an Onyx Blackjack audio interface. In Garageband, I can set the input and output separately, so I can use the default audio output and it pans fine. But in Reaper, oddly enough, you have to chose the same source for both the inputs and outputs, so when I do that, I can't pan while recording. However, when I record something, then listen to it through the default system outputs, I can pan just fine. Any advice?? =(
