Request: Velocity sensitive keyboard keys

Be really useful for keyboard keys If the top of the key was the hardest press and the bottom of the key was the lightest sensitivity…

Like a real midi keyboard, just so there is an X and Y value for keyboard keys. It would allow for the ability to play realistically with instrument libraries, like drums , brass, pianos, guitars etc.

Is there a way of mapping a slider to plugins via CC# so you can control the velocity of instrument libraries?
