Velocity as Modulation Source?

Maybe I just don't see the solution to my problem.

I have tried in vain in the TOUCH module and other places to change the velocity so that a light touch of the key really produces a minimal volume. I am sorry to say that I have not been successful. There seems to be a minimum volume which cannot be undershot. This is a pity, because many instruments would be much more expressive playable.

Apparently there is also no Velocity as a modulation source, which is a shame. Or am I just not seeing this?

Many of my sound designs are based on the interplay of fine velocity tuning and if Soundpaint already has such a powerful modular concept it would be a shame to really give the sound designer the full potential and as much control as possible.
