little tip/trick: the bassline is in the sample itself. What I have is two instances of the sample running at the same time, one with a low-pass filter on it (using the free Prosoniq NorthPole VSTfx), and the other unfiltered (though I should prolly run it through a high-pass filter). during the chorus, I have both running, for the verses, I only have the filtered version which gives you the bassline.
