Any tips how to get rid of OTT artifacts?

When I was sound designing, I used the built in multiband compressor/OTT of Serum and noticed it creates some noise artifacts in the mid-top range. The idea was to create a more powerful sound since it lacked power without the OTT. I tried to get rid of the sound artifacts by using a noise gate but I can't get a decent sounding result. I also tried filtering out the highs but that leaves me with quite a dull sound. Any ideas on how to get rid of the artifacts or how to make it sound more powerful without OTT?
