I have one library, Purgatory Creek Vintage Keys, that loads great and sounds great on the hardware Montage m8x. But, it doesn't load properly on the ESP plugin. Once you get to C above middle C, it is silent or only the note release sounds. Here is a video showing the issue:

I do recall when I first got the ESP plugin, other libraries had this issue also, Chick's Mark V was one. Somehow that resolved at some point. This is my only library to still not be working. Any suggestions? Also, I'm in contact with William Busch at Purgatory Creek. If there is direction I can pass along him as to how to resolve this, that would also be great..
