FL Studio ships with some amazing synths and instruments and one of the most powerful is Harmor. In this video from the course FL Studio 201: Sound Design Workshop, Rishabh Rajan shows you how to use Harmor to create a cool-sounding super saw wobble patch that could fit into any number of electronic productions.
Starting with the default patch, he begins by adding Unison to fatten up the sound with a total of 7 voices. Moving through the synth's control sections he then creates pitch envelope data and then turns his attention to the filter frequency - modulating this is the key to getting the effect you want. You will see that by creating a graduated LFO modulation curve rather than a simple uniform one, he is able to make the effect transition in gradually - a clever trick that will help you make more interesting sounds.
