I created a first rhythm track -> tempo 110. 0 bpm, beat of bar 3then a second pluck track in 60 midi pluck height and a steep fadei repeated the first track, driving the sound very low to give more rhythm to the sound.
This such a crazy beat about huge experience what cowbell make sense such crazy when its fast and much. I use only 4 instruments and it sounds complete. I use program magix music maker.
