Hi,
Welcome.
For that type of sound you are going to need above all a good effects module. I'm not very into this type of modules, but here are some of the most popular

You will also need a pitch sequencer, this is a good option for generative patches

Also very important are the additional modules, vca's, additional mixers, sequential switch
VCA's
