is the malstrom in 2.5? If so, open one up, 1 osc, set to sine, knock it down a few octaves, route it to the filter, then set the filter to comb (cant remember if its + or -), bump up the resonance to about 3/4 and lower the filter cutoff to about 1/8 from bottom, tweek the filter cut off round there, should get a bass that nearly shakes your house down.
