On the synth I've got 2 Oscillators active, a saw and a sine. The saw wave is doing most of the work while the sine is just to make it sound more clean and fill up space. On the saw I've put it down an active and changed the shape which gave me the nice gritty sound I wanted. I also applied a low pass and high pass filter to just get the frequencies around 1K hertz. The attack is brought up a little bit just so the synth rises into place and doesn't instantly hit. Lastly the LFO directly impacts the frequency of the low pass moving it back and forth at a high speed.
