Most people that use software these days have never used hardware, and therefore don`t know how to emulate that sound.
As autechre say, if you can`t make your software produce an analogue sound, then you simply don`t know how to use it.

I hear plenty of hardware stuff that sounds dry, thin and inactive as well.
Plenty in fact. Particularly some techno.

talent, experience and knowledge will give birth to results, there is no shortcut.
