well that ain't gonna get you to generative music - it may be a small step along the way, though - is this what you have now or what you are - I'd suggest that you want a mixer, or better yet a quad cascading vca
I'd probably look at something more 'generative': turing machines, marbles, bloom etc
can't say I'm a fan of the b company or their products, really - I'd go Mantis if possible (for one thing the power supply is more 'right sized' for the case)
If you are confused about the sheer number of modules then I would ignore actual modules for now and think about functionality more - spend some time reading up/watching videos about basic synthesis techniques - both from an east coast and a west coast perspective and then work out what modules you need to achieve that goal

Utility modules are the dull polish that makes the shiny modules actually shine!!!
sound sources < sound modifiers < modulation sources < utilities
