I was trying an effect (I'm on Reason) on a free trial basis that splits audio by aplitude into three bands (let's say -inf to -40dB goes output 1, -39dB to -10dB output 2 etc.), then I've selected some sounds, played a chord progression, the sounds were picked on random, sent the wwith the effect to different distortion units, effects, exported, chopped and that's how I've got the main sample. Decided that trap inspired rhythm would work so added that.
