In that case, you should be able to just put the TimeFactor in one of the aux send/returns on the NI Pro 2 or the A&H Xone, depending on how you have Ableton configured and which device you want controlling the TimeFactor's levels. To synchronize your TimeFactor with Ableton, just connect a MIDI cable from the MIDI Out of the NI Pro 2 to the MIDI In on the Timefactor.
