– Two oscillators, both square waves, with one detuned a bit to smear the sound. The detuning will make the low end a bit unstable so…
– Set the third oscillator to a triangle wave, and turn it up until you hear a nice consistent and solid low end
Filter: Turn the low pass cutoff pretty far down and crank the resonance (“Emphasis” on the minimoog)
LFO: Sine wave, modulating the cutoff. Slow rate. Now you’ll have to tweak the amount and the cutoff until you get the sound just right. You’ll probably have to adjust the resonance as well.
Glide: Turn it up until you hear the pitches subtle slide into each other.
