Disable X1 MK3 mixer mode

First, make a copy of the following folder, so you have the original files somewhere safe: '...\Native Instruments\Traktor Pro 3\Resources64\qml'

Use a good editor like notepad++, open the file '...\Native Instruments\Traktor Pro 3\Resources64\qml\CSI\X1MK3\X1MK3FXSection.qml', go to line 52:

 Wire
 {
   enabled: module.active
   from: "%surface%.mode"
   to: ButtonScriptAdapter {
           onPress: {
             switch (module.layer)
             {
               case FXSectionLayer.fx_primary:
                 module.layer = (fxMode.value == FxMode.TwoFxUnits ? FXSectionLayer.mixer : FXSectionLayer.fx_secondary);
                 break;

               case FXSectionLayer.fx_secondary:
                 module.layer = FXSectionLayer.mixer;
                 break;

               case FXSectionLayer.mixer:
                 module.layer = FXSectionLayer.fx_primary;
                 break;
             }
           }
     }
 }

now replace both instances of 'module.layer = FXSectionLayer.mixer' with 'module.layer = FXSectionLayer.fx_primary', so that in the end it looks like this:

Wire
 {
   enabled: module.active
   from: "%surface%.mode"
   to: ButtonScriptAdapter {
           onPress: {
             switch (module.layer)
             {
               case FXSectionLayer.fx_primary:
                 // module.layer = (fxMode.value == FxMode.TwoFxUnits ? FXSectionLayer.mixer : FXSectionLayer.fx_secondary);
                 module.layer = (fxMode.value == FxMode.TwoFxUnits ? FXSectionLayer.fx_primary: FXSectionLayer.fx_secondary);
                 break;

               case FXSectionLayer.fx_secondary:
                 // module.layer = FXSectionLayer.mixer;
                 module.layer = FXSectionLayer.fx_primary;
                 break;

               case FXSectionLayer.mixer:
                 module.layer = FXSectionLayer.fx_primary;
                 break;
             }
           }
     }
 }

This will make the 'MODE' button toggle between both FX menus (or always remain in the first menu if you didn't activate all 4 Units), instead of going into 'MIXER' mode.
