depends of current layout I want to map different functions on controller buttons
for example:
in Mixer layout - all 16 lower buttons on Xone K3 sets hotcues(and shows status of hotcues), left 8 buttons for Deck A, right 8 buttons for Deck B
in Preparation layout - left 8 buttons are still for Deck A hotcues, right 8 buttons are free to map to other functions and statuses
