Is there any mental disharmony between both versions? I suppose HALion 6 is a continuation of HALion 5 like Cubase 10 is continuation of Cubase 9.5 and earlier versions. Therefore I can run Cubase 8.5 Pro with my license of Cubase 9.5 Pro.

System - Win7, 32bit - yeah, something prehistoric, but it’s not main studion while I’m out of regular studio.
