Hi, can it be that the Level Meters do not work with your file on the (full) X-Touch?
I have two devices in use:
A) Behringer X-Touch -> with your Plug-In (Input/Output MIDIIN2 (X-Touch))
B) Behringer X-Touch Extender -> with the standard provided Plug-In (Input/Output X-Touch Ext)
I use them for VoiceMeeter Potato, A) for the BUS part, B) for the STRIP part
On the X-Touch Extender the Level Meters work.
I tested both, BUS on the Extender, STRIPS on the Extender. In both cases the Meters work.
Can you check if there's something missing in your configuration file?
Thanks!
