I cut the transient from the kick sample on the kicks I wanted to be ghost kicks. (The transient, in case you are unaware, is the very beginning of the sound. It is a very short click that gives a drum sample its punch in the mix.)
This is so good, I watched the stream and it sounds just like the thing (well, a bit different and the vocal chops but yeah). Also, Virtual Riot is my fav producer, glad to see someone here who likes him too :D
