That is INTENSE. This is all about getting the Filter Cutoff just right. Try this:
1. Oscillator: Saw
2. Filter: Low Pass, 24 dB slope, set the Cutoff pretty low (I tried around 80 Hz), to be modulated by…
3. LFO: This will create that triplet rhythm. Set the rate fast, waveform to saw. And then raise the amount until you start to hear those mids. The idea here is that the start of the saw will provide the midsy aspect of the bass, and the end of the saw will give us the bottom bassy sound. Will require some tweaking.
