How to get that Purple Dubstep Sound?

I am looking to make a synth like these in massive or FM8, but I cannot for the life of me find any tutorials elsewhere. I do not want to use chipsounds because I cannont afford that atm. Here are some examples of the sound I am going for.

Any help would be appreciated. (buble)

purple is all about melody and detuned saw waves

Cheers!

The ones decoy posted are way to advanced to what you want to know, its what gordo said; it's literally just 3 detuned saws or any other raw synth. http://gyazo.com/82a5e41e0ddb29e541c0577037236d21
