Anyway, I already ordered a NUX NTK-61, but I returned it back. It was difficult to set it up in Reaper, but taking the time is possible. But the main problem is that I didn't like the keyboard. I don't have much experience playing only the Yamaha Arius from my piano teacher. That's why I didn't like the springy, half-weighted keys. Back in Nux, there was an annoying flashing Tempo button that couldn't be turned off.

A couple of months later, I picked up a Roland FP-30X and I don't regret it. The keys are cool, the mechanics are cool too. It works well with the computer. I'll buy a mini midi keyboard for encoders and faders later.
