Attach the power bit to the split module.
Then, attach one end of the split to a random module set on noise mode.
Next, connect the random to the filter.
Connect the other split end to an oscillator connected to freq in on the filter.
Add the speaker to the output of the filter.
Turn the oscillator knob all the way up, the tune wheel all the way down, and both knobs on the filter all the way down. Then, very slowly, turn the cutoff know up and down to create a wave or wind noise.
