I am trying to use a Behringer XR18 as a passthrough for recording and live sound.
I want route 8 channels from the 8 inputs to 8 outputs for the sound guy while recording 8 channels to Reaper through the USB. I'd like to leave the sound guy completely responsible for FOH and monitors at this point.
There are 6 Aux XLR outputs and 2 XLRs for Main L and Main R. In XAir Edit I can see how to route the first 6 inputs to the 6 Aux outputs with the Aux In/Out menu.
How do I route input channels 7 & 8 to the Main L and Main R outputs? I don't see input channel routing options in the Main I/Out menu.
