1) Pianoteq is amazing, I want to buy it at some point, maybe this BF. Not sure how the Felt model sounds next to LABS/Noire or whatever the NI Felt Piano is, but it’s probably great and Pianoteq itself is amazing.
2) If you mean resorting to Kontakt for like a pad or something, yeah, I feel you there. But for some things it’s the only option. I.E. Audio Ollie orchestral libraries, Performance Samples etc. And if you mean you protest the lack of development, I also feel you there.
