Mmm… maybe I am misunderstanding.
I only have Dark Planet but figure Triebwerk (and others) would work the same. The sounds for Dark Planet show up in HALion Sonic SE2. Just press the “load program” button and type “dark planet” in the search field.
I figure that all of these sound sets would work the same as it is stated on the product “Spec & Downloads” pages that a “VST 3 or AU host required” for Mac OS X, and “VST 2.4 or VST 3 host required” for Windows.
