To add to what I said, with the above in mind, I have no use-case for Pianoteq. It’s not good for recordings because it can’t produce lush piano sound quality.
And for practicing I prefer the onboard N1X sound because it is the most playable and honest sound. Yamaha made sure every single key is spot-on and responds as it should. The sound is not as beautiful as a huge sampled library but then those libraries are just too nice sounding and hide my errors, I can’t learn and improve effectively. And Pianoteq is too bad sounding and that distracts me too. Besides, Pianoteq is never playable for me out of the box and I have no time for per-note edits. Not even sure that would help.
To summarize: huge sampled libraries are unmatched for producing high quality audio recordings for my YouTube videos. The on-board CFX of my N1X is unmatched for learning and practicing (second only to a real acoustic piano). And Pianoteq is of no use to me.
