SM Drums is a free VST plugin that is probably one of the best drum plugins out there, it sounds even better than those paid plugins. This plugin was created by Scott McLean, Tod Stillwell, and Suleiman Ali.
I have tried a lot of drums by now but this has to be my favorite drum plugin and I have also created a bunch of tracks with this one.
The plugin works on top of the Kontakt player, SFZ / Sforzando, and also on the reaper. The creators of this plugin have put a lot of thought and effort into this.
