Need a few info

Can somebody explain to me how to make the basses in the drum and bass tutorial in a windows synth ? It would be really helpful. Please don’t expect me to be a pro I just know the basics ( that means if you use the words that are used in the certain synth i can understand them ) . Sorry for the grammar , i’m not english.

The same style of synth sound is used in the Fidget House and the Dubsteb tutorials.

They both use sylenth which is windows compatible
