Also, a lot of the "awesome" sounding stuff uses additional effects such as Unison (generates multiple waves with slight pitch differences, first tab of Sytrus) and then in the FX tab you have chorus, delay and reverb while in the 3 FIL tabs you have preprocessing in form of cut, envelope and resonance, most of which you should already be familiar with from other generators. You can also chain these filters so that FIL1 sends it output to FIL2 and so on.
