Plugin to make hihat sound lower in drum loops?

[SamDi]

What about multiband compression with filtered sidechain? You need a MB-compressor, where you can set the sidechain frequencies independent from the compressor band frequency borders.

Then find frequencies, which are emphasized most, when hi-hat is triggered. You can boost these frequencies and filter the other ones with an EQ in the sidechain to find a threshold value afterwards to trigger the compression on this band.

The art of doing this of course is to find appropriate frequencies in the sidechain and compressor bands to detect and separate hihat from other sources. And you are dependent that there is some difference in contained frequencies. If for example the snare contains in each frequency band more energy than the hi-hat, then it wouldn‘t work.

Otherwise, there is a chance, to reduce the disturbing frequencies a little bit…

did anyone mentioned soundbrigade from sknote ? ...for that kind of task it can give a very surgical touch to your mix ?

Slice it up as much possible, delete the hihat slices, and eq them out from the slices that also has the kick.
