Here are a just a few tips on getting getting started... eventually this thread will grow with more advanced features with contributions from more advanced idmfers but here is just the basics for this genre.
lets that with that huge wide ambient riff that is the bones of dub techno. In my demonstration i will be using cubase 6.
so lets fire up cubase or your daw and open up a simple analog type vst like cubase prologue or abletons analog.
Lets select the sawtooth osc since its very rich in harmonics. we will also want to be using a 24db lowpass filter since this will let us get some nifty lower/mid tones. we now need to set our voices to more than 1 lol.. i would say at least 4. lets create a few bars worth of the same chord, and we want a slightly low octave. turn on the cycle mode and repeat it. it should sound pretty harsh and gross, but deep as well.
now lets get to the soundgoodizer part.. the reverb..
lets now slap a simple reverb on this and shape it to our liking. lets start by setting the reverb time to somewhere along the lines of 10 to 13 seconds. this should have a drastic effect.. now move down the diffusion and size to pretty nominal values so we can create a clearer image of the sound and mix around 60 percent for even more clarity. bingo.. you should now have a pretty deep chord. tho something is still missing.. we also need some simple ping pong delay going on. fiddle with the settings a bit.. tho i recommend starting with 1/4 timing.
