I was successful in configuring a Behringer X-Touch and X-Touch Extender in SAC.

I am struggling in SAW.

In SAW, under Midi Device Setup, there is only one device to to configure. In SAC there are three where I chose X-Touch Extender for Device 1 and X-Touch for Device 2. (I have the extender on the left of the main unit).

In SAC I chose MidiCtrl_Mackie_MCUPro_16Ch_Ex_Pro.mct as the Midi Control Template. As far as I can see, there is no corresponding file in SAW.
