Big room hose

If you are referring to those rhythmic pulses (not the bass or other sounds), they are low notes of probably sawtooth (although all the other sounds seem to be composed purely of square waves - sounds like an intentional choice of the artist), that are filtered through a lowpass or bandpass filter with some resonance, which has its cutoff frequency modulated from high to low very quickly (use the filter envelope or LFO in envelope mode) and then passed through distortion.

Hope this helps.
