One of the defining moments in electro-house, this makes heavy use of a distinctive square wave lead sound that can be recreated on any three-oscillator mono synth.
Select square waves for the first two oscillators. Make sure they’re set to the same octave and dial the fine tune to -10 on one and +10 on the other. Mix them at equal volume. Next get a saw wave up on the third oscillator and set it to one octave below the other two, then adjust the volume level to about half. You should be well on the way.

How to get the sound
We’re using Logic’s ES2 here. Select a 24dB low-pass filter with a hint of resonance. Put the cutoff to around 30% and set the filter envelope to half way. Set the ADSR to A=0, D=50%, S=0 and R=70%. Finally, set the Amp envelope to A=0, D=50%, S=100% and R=25%. Lastly, there are a couple of moments where the portamento/glide is used at quick settings.
The sound is pretty dry in the mix - there’s no noticeable reverb or delay to be heard so you might want to add a touch of drive, compression and ensemble chorus to finish it off. There’s also a second layer an octave down playing simple variations of the main riff. This is a simple saw wave but raise the low-pass filter up and down to create dynamics.
