Most if not all older VST's including effects and synths from many mfr's (NI, Arturia, etc.) provide a little "camera" gadget in the upper right-hand corner of the synth/effect GUI (properties). (hope I'm using the correct terminology). Just click it, and a thumbnail picture of the GUI replaces the gray blank square in the media bay. The following NI synths/effects do NOT provide that camera gadget:
Massive X, Battery 4, Bite, Choral, Dirt, Flair, Freak, Guitar Rig 6 Pro, Phasis, Raum, Replika XT.
since there's no "camera" gadget, I can't replace the gray square with the GUI thumbnail.
if this question has already been answered, then I apologize for cluttering up the forum. I simply didn't know how to search for an answer to a cross-vendor interoperability issue.
by the way, the instruments and effects work FANTASTIC, even without the picture. 😁
