I beg you pardon if I post this in a wrong discussion. In my previous Windows installation, everything including the pink and blue graph display of BC Triple EQ worked fine on equalizerAPO except the playback/output meters inside plugins didn't update. My laptop was bricked in the boot stage and I had to reinstall windows. After that, I was reinstalling my programs in kind of a rush and afterwards I got this strange miss of the graph I used to get.
Reinstalling didn't work either. And I guess it's the latest version of the plugin.
