OK, here is what I did, and I found it by mistake. I pressed the upper layer switch, and then hit the select button for the FX1 return, and then hit the routing button to open up the routing screen. And to my surprise under the FX sends tab, FX1 was turned off! So after switching in on, the FX comes thru just fine now on mix 1. No wonder it was not working. It is baffling now that FX was working on the FOH. Eventually I will get this figured out. Again thank you for all the help. So if I read the response from MarkPAman correct, If I choose Pre I will get the FX in the monitor even if it is not going to the FOH? I am going to go over to the unit and give it a try.
