Hi Alexey,
Is it possible to get the right page/right layout automatically appears with the context on PC screen ?
For example : PC screen is tracks, then Touch screen on tablet is page 1
PC screen is FX, then touch screen on tablet is page 2
etc etc...
Yup.
Add a control with a "Monitor" "State "Context". In the feedback section send "/1" ("/2", etc.) corresponding to the current State.
