I've been playing with the demo of VE Pro. One problem that I'm having is that one of my Kontakt libraries has a strange legato issue. It works fine in Logic 9, but loaded in VE Pro I hear a weird sfz decrease in volume and the last-played note is stuck on.
My system:
Mac Pro 8-core Nehelem, OSX 10.6.2
Logic 9.0.2
VE Pro demo 4.0.4416
