Í'm not a DVS user, so have my experience from the forum.
AFAIK the LE license with the Xone also has DVS available as feature.
DVS is an audiostream so has nothing to do with MIDI.
Did you calibrate the DVS setup? In preferences of Cross.
You could try the demo version as this is full featured with time constraints only
