Is the Battery User Manual and the Support page on Native Instruments wrong about the file extensions accepted by Battery? It says that Battery accepts only Kits with the .nbkt, .kt3, and .kt2 file extensions. But, I have a lot of Native Instruments Expansions, and many of their Kits use the Machine file extension (.mxgrp). And those Kits seem to load just fine in Battery (I do not own Maschine).
