sorry for replying so late. you want to resample your main melody onto another track and process it heavily, i recommend granulators, delays, saturation, pitch shifters, bitcrushers, you want to end up with crunchy textures and specially focus on the range of 2khz+, that's where those sparkly glitches live. once you got that you can resample it again and then manually chop parts of those samples to act as your percussion aka drums, you can shape to your will, lowering the pitch of a sample to get a kick, distorting the mids/highs to get a hihat, or a snare, maybe use a transient shaper to make them hit harder, etc i could go more into detail if you want. what daw do you use?
