Audio In (via side chain)

Hi all,

Does anybody knows IF (and if…, how) it is possible to use the VST3 “AUDIO IN” feature with Halion (via side chaining the incoming audio)? I can get this working with Retrologue, but doesn’t seem to get it going for Halion, although Halion is giving me the side chain button?!

Would be absolutely great if I’ll be able to use the halion filters and modulations and such on a incoming audio stream.
