hi. newb to reaper and how to set up interface to work properly. i have a mackie blackbird 8 preeamp interface and reaper. mackie comes with a software mixer. my problem is i cant pan in reaper. i, for example can insert a track in reaper, test with a mic inserted in input one on interface with recording input also one in reaper. i get vu's. it will record. but when i pan the track it does nothing. i can pan 100%left and render, but only mono is rendered. what am i doing wrong? what do i have set wrong? i can monitor what the interface is doing and pan from the mackie mixer utility and it pans fine. i have even tried panning the mixer utility input one and reaper track the same and no change. stereo is enabled on master in reaper. thanks for any help.
