I've copied countless tutorials, read many threads and have scoured for information on this sound but the best I could come up with are Jaymac's and Seamless's tutorials on youtube, although I've had a bit of trouble finding a definitive answer for getting this sound. It seems to be FM8 through a vocoder from what I understand, although the likes of Zomboy, Knife Party, and Skrillex have got it down better than the tutorials by far. Its that very organic and unpredictable "blargh, blap, flip-a ,thrap, fromp- a wop- whaaaaaaaap" that I am after. I could name a few tunes to be specific if I had to. Im very sorry if this a vague or disappointing first post, but I had to join to ask because it seems like this gets mentioned on the growl thread but I feel it is something other than a growl. I like Jaymac's term "squishy bass" because it sounds so wet and not always that growly.
