The mapping itself is sorted by button for easy reengineering. If you are into mapping, the other two JPGs explain which midi key is assigned to which button.
I don't like doubletapping Sync for that. In case you don't use beatsync and the remix deck jumps out of phase there is a dedicated PhaseSync Trigger on the button in the bottom right corner, the one without LED feedback. As per request, the Slots are arranged horizontally. There are four toggles to switch the 8x8 Matrix Buttons between.
