How to Make Dissonant Hard Techno Leads in Serum

I use three oscillators to create a lot of dissonance. The sub is a saw wave, one octave up, and it's the root.

Oscillator A goes one octave up and semitone plus two. Oscillator B goes one octave up and semitone plus three.

I add distortion on Zero Square to really squash it, a compressor to glue it together and an EQ to cut the bass.

Then I add a chorus in front of the distortion to add some wideness, and take down the depth.

Go back and change any wavetable to create interesting variations. You can also change the semitones and create a different dissonance.

Play around with it, because it fits hard techno perfectly.
