I’m not sure about rmhewa’s question as I’m not sure I understand what he’s asking.
But for H DTU’s question. Yes, you can send FX to the monitor outputs, all 6 of them and the levels are controlled by a fader for each output, so each output can have differing FX levels or none at all if you so choose.
It’s shown on page 48 of the manual, where it says at item number 11.
11. In the processing screen, select the ST, Inputs/FX tab
12. Select the FX unit channel, then touch/click SENDS to show all send levels from that FX unit.
13. Adjust send levels to the Main LR, Other FX units, and Ouputs 1-6 as required, so the FX is heard only where it should be.
Note that this screen also allows you to send the FX output to another FX. So you can “chain” FX if that’s what you want to do.
