I don’t know- I think the main benefit, personally speaking, of the NI Kontrol is the automatic integration with a HUGE number of plugins(granted most are the processor hungry NI instruments), but also with the Arturia plugins along with Plogue and Korg Gadget crossovers. I don’t know why the hardware approach to sound design is so rare in demand, but that’s my big draw towards the Kontrol over this impressive keyboard.
That being said, I’ve onlg done a gloss over investigation of the Novation and have yet to see the Loopop video. But based on what I’ve seen, I can’t imagine it having the tight integration with the synths/plugins themselves
Edit: while it’s cooler than I initially gave it credit, one thing it’s missing for it’s Ableton integration is a one-button capture trigger.
