I based the sound off of a DJ SoundKiller's Drum preset pack patch. The pack if free, just search "DJ SoundKiller 1000 subs special!" on YT and it should show up. As for the speed and automation, I just messed around until it sounded right. As for post processing, I used some OTT, some soft saturation, and a soft clipper to really bring out the sound. Then I used one of my generic Ozone 7 presets for mastering and of course slapped on a -0.1 db limiter :)
