I honestly don't know how to turn them up/down so I guess the answer is "I don't know".
There are some things that your scene is telling me that are wrong that I don’t how you got it in that mode. Since I am just using X32edit to look at your scene some things probably don’t display in Edit that would with a mixer and whatever else hardware like stage boxes and the card. So without all of the information it makes it hard to troubleshoot. So I have a couple of questions
Are you using a remote stage box like an S16 or other remote stage boxes? If not why on the setup page do you have synchronization set to AES50a? Unless you have a really good reason that should be set to internal even with stage boxes.
Are you using another mixer on stage as a monitor mixer that is connected to this system?
Is this a full sized X32 or one of the smaller ones?
You can try to track things down by muting everything and bringing up things one at a time and see which one gives you a problem. This is the kind of thing you do when you aren’t doing a show or a service. You also need to mute the outputs and trace them to see if you are really getting things to where you think they are going. Most of this can be done by playing something thru a couple of channels (like an MP3 player or you phone) and see what goes where you play with the sends on those channels, including sends to the effects.
Where are you located? Maybe someone is near you that can come over and help you.
The fact that you don’t know how to turn the effects up and down worries me. You have stuff being sent to the effects. The returns are the faders that are labeled FX-1L thru FX-4R. And those are being feed post fader to Mix Bus 5&6.
Also Mix Bus 1&2 seem to be for monitor outputs but I don’t see where you have them assigned to a physical output. I may be wrong but I think that the way you have it routed that Mix Bus 5&6 are going to the X32 Output 1&2 XLR and to the AES50a XLR outs 1&2.
How are you getting the outputs to your main speakers? What is the routing.
BTW it is a very good idea to label all things on the scribble strips as to what they do or where they go. It makes it easier to remember what does what and it makes it easier to trouble shoot.
