Message from pianoteq

Hello,
I wish to have some clarification please and assistance.
I have been using the demo version of Stage Pianoteq and during the velocity calibration in it, I received a message that my Keyboard does not use note ON/OFF, the rest of the velocity procedure went well.

But my DX 11 has NOTE/OFF under its midi settings: It is set to ALL.
here is the manual on page 18. no. 8
http://www.synthfool.com/docs/Yamaha/DX...Manual.pdf

So, should I disregard this, as long as the rest of the calibration procedure went well?
Because I am thinking to buy the full version, but I do not want anything missing. I need a Piano and you understand :-)

Thank you for any help
BEST
