I just found this thread:
“Verve” not appearing in Halion 6/Sonic/SE - Cubase - Steinberg Forums
I’m not sure, but it sounds like you maybe can only use items that have Steinberg Licensing with the SE version? It’s confusing. It would be nice to have it confirmed that I should not be able to see Verve in Halion 6 and Halion Sonic (non-SE).
