USB audio need to be able to enable/record/select the inputs for both DI and monitor out (master stereo)

    I just moved to Windows from Mac and maybe I'm not finding the correct driver but it seems like I should be able to have signal from 1 and 2 as stereo master to one track in DAW (Reaper) and signal from 3 and 4 to another track as a DI.

    can anyone school me on this?
