i disable sound variation mapping if found notes what used variations are disabled they dont go plugin (plugin gui not react its Kontakt 6). i haved track one virtual guitar with custom soundvariation map file. disabled it becouse i loaded one my virtual accordions (what not of course use this mapping) its all notes not play (ones what used keyswitch this map). they play fine when this mapping is on. also if select CUSTOM soundvariation map what is empty default state is only way disable whole feature? (after i used it). seems at least confusing if not buggy.
Studio One Pro 6 is latest. if someone wants i try write my native tongue if someone can try translate it.
