Completely agree... but I think is important to understand the diference between volume and velocity.
In NWC crescendo (in fact, every dynamics) changes the velocity values (the force used to play a note) while Volume MPC changes the volume of a note (or track section). Usually more strength playing a note means more volume BUT it also means more intense playing (obviously, with a different sound of the instrument). Much VSTs or multi-sample instruments today use different samples for each velocity, so if you reduce the volume of a fortissimo you won't get the same results as using a pianissimo dynimic change...
Think about it
Keep enjoying music, friends!!
