For Ernesto’s first suggestion insert/dual mode doesn’t matter.
If I understand your first diagram, that is an insert mode implementation with two mono inserts but there are problems. For example, you have some of the insert ins and outs connected backwards.
I don’t understand your amp connections in your second diagram at all. Again, though, it looks like you have some ins and outs mixed up.
You may want to look closely at the insert mode diagrams in the quick reference guide and manual. Perhaps you can start with the two mono or one stereo configurations. After that works properly for you, try adding more. I’m slow. I take baby steps!
