I tried Smart Gate on Kick In, Kick Sub, Snare Top, Snare Bottom, Hats & 8"/10"/12"/14"/16" toms.
In my case all of these were "fixed" right out of the gate (see what i did there?) except the hats. In this track there two sets of hats. They both required just a tad of tweaking.
I'm pleased with the results of this plugin.
