now that you mention it, i had the same, but only with BIAB 2019, i found mine working when i set the VST's output to audio channel 16 .. it worked since, and forgot about it. I checked it just now and reloaded it; found the main output working now. Beats me, LoL. PS i dont have SE installed but Halion 3 and Halion.
