You can program that kind of bass with any synth that has a good lowpass filter..
I believe it\'s mostly done with a sawtooth lfo (|\\|\\|\\) on the filter, and then using a couple of detuned square\'s on top of each other running through this filter.
Then you can use the mod connected to the filter to open and close the filter so the lfo becomes more or less pronounced.
I usually do that \"pulse\" with filters and ride the filter in real time.
I built a gnarly synth sound on my Korg Analog modelor. Really small patch tho,...needed to be for the project I used it on. I got nice results just riding the CC11/volume control but thats because I couldn\'t use filters on it
