Dynamics Parameters

I would like to see dynamics parameters or sort of control over that on a per instrument basis:

- Velocity response curve
- Velocity target range
- +/- constant

I find it difficult to get the right velocities for my orchestral library. There are often hefty jumps and annoyingly extrene contrast. I acknowledge this is not Synfires fault, but some utility to better cope with this would be great. Editing the velocties manually just doesn't cut it.

Edit: I believe this is mostly because imported passages all use different dynamics. There should be a way to normalize this, or kind of that.
