Use 1 osc. Use Squ-Sw1 (the sound that comes up first anyway) Turn your WT position knob all the way to the left, turn the pitch down to -12.00 - Go to Filter 1, choose low pass 4, and have your cut off knob facing about 10 o'clock. Turn the resonance all the way down. Go to 5 LFO, click on the 4 arrow symbol (has an arrow facing in every direction) then go and click on the box under your cut off, the first one on the left. There are 2, with this symbol underneath is - (a hyphen)
Go to your 5 LFO, set it the ratio to 1 over 8
So... 1
8
Set the 2 wavetables to the sideways S. I think it's a sine wave. Go back to your cut off, and click and hold down on the 5, and drag down a little bit, until you're happy with the amount it's cutting in and out (slightly, very slightly is closest from what I did, or else it's too in your face)
Now, from here - finishing touch. Go to your 4 Env, make sure delay, attack and release are turned all the way down. Decay, and the 2 level knobs all the way up.
That should just about do it. Even maybe put some Chorus or reverb to make it more interesting, but do it wisely. Hope you can understand that.
