As you said “humanise”, it made me think “don’t play straight 16ths”. It’s very rare to find a human drummer play that pattern. They usually mix closed and open hats, or they play ghost snares on some of the 16ths, rather than closed hats. Sometimes they alternate tiny snare hits and closed hats. I’m not sure, but maybe they also do that bounce trick on closed hats (where they strike down once, allow the recoil to push the stick up and then use a slight finger pressure to push the stick down again)? With the bounce, the alternating strikes will sound slightly different because one has the full arm force behind it, and the other the looser finger force. It’s also harder to do, so every other note will have higher chance of microtiming changes.
