Yup LFO's and maybe play around with the ADSR a little as well just for fun. I'd probably go for z3ta+ rather than Dim Pro for dubstep bass.
Here's a base [pun intened] to start from with z3ta+: Detuned Saw (use two oscilators, one a little sharp and one a little flat), 100% Bus, Sine LFO synced to the tempo you want routed via the matrix to control the filter cutoff.
