Here is the velocity curve I use :

Velocity = [0, 9, 30, 73, 100, 118, 127; 0, 8, 22, 56, 82, 106, 127]

This digital piano have a fantastic touch (real grand piano hammers !) but samples are outdated : same samples are used for 2 or 3 notes, only changing the pitch. Very annoying once you have noticed this effect.

Fortunately, Pianoteq is here to give a new life to this very good instrument.

I raised a little bit the ppp because it feels more natural, maybe due to the quite noisy real hammers.
And then I added a kind of exponential curve to get a better control of the level.
