I have "Alicia's Keys" and noticed it doesn't respond to any of the tuning parameters in the project settings. Is this just the way some sample libraries work? Or is something else funky? EXS24 piano responds just fine.

hmmm... I haven't got Alicia's keys to try this out. Have you contacted NI support? Best, R

I haven't. I was thinking it might just be a limitation when working with certain sample libraries. I take it by your response that this isn't the case?
