How to Make Detuned Hardstyle Chords in Serum

I set oscillator A to a unison of 16, and oscillator B to a unison of 16 and one octave up.

Then I add a poly of 32 so you can play a lot of voices.

For more chaos and detune I take LFO 1, disable the BPM, set a high rate and add it to the fine tune. You can change this to make it less chaotic.

For even more detune I add the chaos to the coarse pitch, increase the rate of the chaos until it's very detuned, and take down the output to your liking.

Finally I assign macro 1 to the detune of both oscillators, so you can change how much detune you want.
