UR44: DAW/Input Mix, where is it?

I’ve used the UR22 for a few years and just got the UR44. On the UR22 there’s a knob on the front panel that controls the blind between DAW and Input but it’s not on the UR44. Where do I control that?

I use Ableton and the Monitor “Auto” doesn’t appear to work correctly either. The input to the UR44 is sent to the monitors regardless of the setting in Ableton. Is the solution to both of these issues solved by use of dspMixFX software? Or do I need to upgrade the driver for UR44 so Ableton monitor functions correctly with the UR44. I’m trying to not use dspMixFX software if possible.
