How to make a The Lonely Island (feat. Akon) I Just Had Sex-style synth sound

Step 1: The analogue synth sound from The Lonely Island (feat Akon)’s I Just Had Sex is made by running white noise through a filter and sweeping the filter’s frequency with an envelope modulator. In this case, it’s layered with another, similar patch. We can do this using a modular host such as energyXT2, and a freeware synth like TALElek7ro from Togu Audio Line. Open the first TAL-Elek7ro in XT2’s modular window.

Step 2: The sound starts with the swept filter noise. TAL-Elek7ro’s default BS Startup patch is fine to start with. Begin by cranking the Noise knob in the Mixer section fully up, and bringing the Osc 1 and Osc 3 knobs all the way down (Osc 2 is already silent) so that all we hear is white noise. Play and hold a note for a second or two. It sounds like static.

Step 3: Go to the Filter and turn the Cutoff down to around 8 o’clock, then turn the Reso knob up to 2 o’clock. Let’s use the filter envelope to modulate the cutoff. Turn the Contour knob up to 3 o’clock, set the Filter Envelope’s Attack to 1 o’clock and turn the Sustain all the way down. The Decay should be at 9 o’clock and the Release up at least half way.

Step 4: Now the filter cutoff fades in before decaying to a silent sustain. We need to tweak the Amp envelope, too. This time, the Attack should be about half way up, the Decay a little less, the Sustain down all the way and the Release at just past 9 o’clock. Sometimes this sound is layered with another underneath it. So, drag another TAL-Elek7ro into XT2.

Step 5: We need to delay the onset of the second synth sound, so let’s patch one of XT2’s Multi Effect Delays in between the new synth and the Audio Out module. The Delay should be set to 100% Wet, with a Feedback value of 3, and both Left and Right delays set to around 700 (depending on your song’s tempo). Once again, turn down the oscillators in the new synth.

Step 6: Don’t turn up the Noise, but do crank the main Volume. Turn the Filter Cutoff all the way down and the Resonance all the way up. Contour should be all the way up, too. The Filter Envelope’s Attack should be at 1 o’clock and the Decay, Sustain and Release at 0, with the Amp Envelope set similarly. Play and hold a note. That’s it! Fine-tune as required.
