MOTU tech got back to me with a video file reply - very cool, very helpful!I just reported this VST3 issue as a Tech Link at MOTU and referenced thread here:
Maybe if enough of us make some noise about this they will expedite a resolution. In the meantime, I'm really enjoying the use of Studio One 5.3, VST3 instruments, and automatic sound variation (ariticulation map) creation.
They are working on Kontakt 6.6 VST3 passing the plug-in scan but can't say when this will be resolved.
They also pointed out that automatic creation of articulation maps is not an absolute given with VST3 plug-ins. The function needs to be available in the plug-in.
