not shure either ,,but might have something to do with re mapping the controller to control the c/d decks ,,

there is a MIDI napping utlity and also a Cross map app ,, get info and assistance will be there

its far beyound my reach to help you re map the U-Mix Control Pro two ,,but have looked at MIDI tab in 2.5 and there is a section for editing and remapping the player 3 and 4 ,,
my only thoughts and concerns would be how to use the software Cross fader to transtion between tc vinal and digtal
,kinda think you would be limited to transtioning from deck 1(tc) to deck 4 (digital) and the inverse from deck 2 (tc) to deck 3 (digital)
