This is the standard that most of producers work on. In these type of projects the base is original from the producer — chords, melodies, leads, etc — but it contains additional melodic elements that complement the track and come from royalty-free sample packs. They are usually vocal chops, real instrument chords or textures, wobbles basses, glitch effects, etc. In a project file of this category you will find MIDI files created by the producer, but also melodic loops
Process note
Coming in Hot with energy and drive, this Drum & Bass track is strong, rhythmic, and driving. There's a LoFi Dub Male vocal on top that adds a more halftime feel to the sound, and his voice and lyrics sit real well in the song.
Some Solid animal, Synth, and FX Shots throughout, adding range and peppers of interest, while still allowing that bass line to ride out.
