Question

I downloaded a saturation plugin but the scanner keep ignoring it. I even downloaded a different plugin but the problem still continues

Answer 1

Try going to Studio One > Options > Locations > VST Plugins and double check that it's in on of the the locations listed. If not add it. If it is, click on "reset blacklist". If it still doesn't work after that I would verify the second plugin is the 64bit plugin and not 32bit as S1 ignores 32bit. Good luck.
