Was this issue solved? I just installed Synchron myself and am having exactly this issue.
Database paths looks fine - not crossed out. Various articulations will not play - legato more often than not but not always.
I am running Synchron as a plugin in an instantiation of VE Pro Server. All other VE Pro6 instruments have always and still are working fine. The VE Pro Server environment is running on a MacBook Pro and sending via ethernet to my ProTools rig on a MacPro. Has always worked beautifully.
Any help appreciated!
**UPDATE: solved. I realized the SYN SE Vol1 had not been sucessfully INSTALLED, only the PLUS. Hence all the missing pieces. Fixed.
