I used 2 low frequency operators (lfo) on a low pass filter (24db) on a generic pink noise sound with medium resonance settings, one of these lfo's was manipulating the other one with a random ramp, to make it sound more diverse and realistic. I put an aditional long envelope on the q (resonance) also, not to mention some chorus at a low tempo to make it kinda binaural with a stereo delay at a short time setting. . . I hope you enjoy it!.
