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.
The track was made thinking about the groove, to work on dancefloor, so i used a lot of drums and a cool groove on bass!
Sample pack Jackin' & Tech House 2
Loop name 03_JH_Synth_Loop_C_125
