Well I think its kind of more about finding the right base setting. . then from there you should be able to tweak in many directions and get really mental sounds..
basically i would say finding the right balance of sync & FM depth and choosing a good combination of oscillators. . . this should create the basic sound texture. .
then use the filter, the effects, the envelope etc. . to deal with it from there - tweaking sync can be good, great for some strange sweeps. . but tweaking FM depth usually results in a horrible out of tune mess.
but yeah fm depth and sync settings seem to add the most character to a sound.
*edit* just recorded myself having a bit of a jam to a simple 2 bar midi loop i set up... have a listen if you like. . lots of reso/distortion editing. . sync too . . well everything really hahaha. .

*double edit*
I forgot the Scene Morph knob . .thats cool...
Basically you store a variation of a preset in each scene morph position (theres 2) . . so like the oscillators are the same type and such, but any knob differences are saved. . then you just turn one knob and it morphs from one to the other changing all the settings. . very cool
