KORG's Pa-Series arrangers have had all that for years. By default they can do volume, Cut Off, Resonance, ADSR and effects direct from the factory on the sliders and outside that you can assign other functions to them.

You can even control an external PC or keyboard direct from the front panel of a KORG Arranger.

i was just about to post James and you beat me to it.

I suggest you have a look at the video again, and you will see that the assignable sliders on the Korg arrangers pale in comparison to the real time assignable controls on the XF.

I am talking about REAL TIME Assignment of all the ADSR etc. controls, and not having to keep going into menus (Or storing them in a pre-set) every time you need to change a function on a track.

But that is just real-time control of a sound.

A Korg arranger and any other arranger has better real-time style control over the XF.

I don’t know about the PA 2x pro, but on the XS and probably the XF, each of the 8 knobs have multiple functions.
