So I am using Project Sam Orchestral Brass Classic with Sibelius 6 using kontakt 4. The patches sound great until I try to change dynamic markings at which point the samples become out of tune not only with each other but with themselves. Furthermore I find that the initial velocity of each patch is quite low and increasing the volume on the patch itself doesn't work as it resets automatically upon playback.

At some volume levels the patch is in tune but there is a very soft sound behind that is out of tune.

I really love the sound of these patches but I have no idea how to solve these problems. I've looked everywhere for some documentation or troubleshooting tips but I cannot find any.

Any help would be greatly appreciated.
