Its never anything that’s affected me or troubled me in playing/programming. Like many pianos, it’s the idiosyncrasies that defines it’s character.
That said, I brought into the LABS range before the rebrand when it was a range of small Kontakt Libraries so could open it up and tweak if I ever need to.
It you’re looking for something similar but with more control, Spitfire took the Yamaha U3 from LABS Soft Piano and re-recorded it at AIR Lyndhurst, packaging it up in the Originals range. It’s a bargain, Look it up. Originals: Cinematic Soft Piano.
