Thanks for the response Dave. I'm still having issues. I think my iPad screen is a little different from what you're describing. Here's what I see: it can't be that difficult - not sure what I'm doing wrong. I have the bus sends set to Post EQ and the effects sends set to Post .
I'm new to the XR18. I'm using the X-Air iPad app to control the mixer for live sound. I can't figure out how to place the effects into the monitor mix (aux outs) as well as the mains. I can get them through the mains - just not the monitors.
