Im not a fucking expert on trap, but Im pretty sure most of what is called trap these days doesnt sound like that first vid and isnt 106BPM. And that TNGHT vid lol, he is goin into bare detail of making that melody out of loads of layers, and Im pretty sure the guys probably just used one sample of some percussion, pitched in a sampler lol.
Not hating on you wub for posting them, its just i wouldnt use this guys videos if i wanted to make trap or juke lol
