Unify - adding an algorithm to simulate realistic expression curves

hello to all

I use an expression pedal to play with Unify. 

this pedal works well. but it doesn't allow to play realistically,  (especially with very precise physical modeling VST like SWAM Strings).
i tried to use different kind of expression curves but it doesn't solve the problem at all.

the problem is : when you use an expression pedal you move your foot from back to front and back again (great for guitarists).

except that it's just as easy to be at maximum and back to minimum !!. if you play a string instrument and set the CC of the VST instrument to expression , it give you a non realistic sound ! and it very easy to understand why.  for ex when a violinist expresses the maximum intensity of his violin it requires a lot of energy and he will generally never go from min to max expression of the violin as easily as with an expression pedal that goes back and forth  as easily as a mouse click !.

the solution is necessarily algorithmic. i.e. if i press the expression pedal there must be some latency before the maximum value of the curve is reached, simulating the effort to achieve the max value (it's like climbing a hill the higher you go the harder it is) and vice versa.

the latency must also follow the backward movement. this would allow to arrive slowly on the values of high expressions and inversely to return slowly to the minimum level.

clearly when you switch your pedal from back to front and vice versa, Unify should integrate an algorithm of latency to simulate a king of inertia and be able to parameterize this curve inertia  (delay starting , force of the curve, etc..)

it would be necessary to be able to parameterize that for any curve. by default the parameters would be those of the actual behavior which can be appropriate for certain instruments (ie synth / cutoff for ex) . 

should it be possible to integrate this king of algorithm for curves ?
