Sound design is absolutely, completely, 100% possible using software synths. Sound design is possible using a Casio Keyboard. It's possible using a $30,000 Eurorack Modular Synth. It's possible using a Sure SM57 and a styrofoam cup. There is so much evidence supporting this that it's not even worth arguing, but the best evidence is right here in this submission.
Not only did you heavily experiment with sound design and synthesis, you formed it into a cohesive song. This thing is bangin. You got me praying for that kick to hit again and got me begging for a bunch of spicy frequencies to hit my ears. My only critique is that I want more of your percussion, because you're damn good at it. The ending segment with snare on the 3rd beat felt like ecstasy. I wish there was more "oomph" in the bass during this section, like the insane cerebral kicks around 1:25.
Nice work!!
