Guy,
Did you use lower velocities for this demo? If so, do the higher velocities have a bit more high end? It sounds a lot rounder than the other VSL libraries.
Did you roll off or in any way adjust the highs? Perhaps you could comment on the making of this demo.
Thanks,
Jack
edit: I'm referring to the strings only demo here.
The main core of the appa demo is the cellos, the velo varies between 20-90, the violin goes higher in the upper melody. I didn't change the eq.
