The base is original from the producer (chords and melodies), but is complemented with elements that complement the song that come from samplepacks, usually, vocal chops, guitars, wobbles sections, glitch effects. It is the standard in which most of producers work, in a project you will find MIDI files made by the producer, but also melodic loops.
Most of the basslines were made with Serum and Massive. For some synths, I used Bass Music Packs, mainly dubstep/riddim, but they were processed and pitched to fit in to the song
