This tutorial is meant for more Electro House style music. If you're one of those people making another pony dubstep song, sorry.
STEP ONE: Create a combinator with a Line Mixer 6:2 in it. This is the beginning of pretty much every synth I ever make in Reason, and the same goes for this one. Once your combi is created, throw in an instance of Thor and hook it up to your Line Mixer (Make sure it's initialized!). Next, turn the decay and sustain in the Amp Envelope all the way up (Maybe turn the release up just a bit if you want a more Video Violence or old school Electro style buzz). I usually use all three oscillators in my synths, setting the types to the following:
Osc. 1: Analog, sawtooth, octave 3
Osc. 2: Analog, square, octave 3 with the AM from osc. 2 all the way up
Osc. 3: Wavetable, Mixed Waves 2 (Pos. 44), octave 3
Route all three oscillators into Filter 1 and set it to bypass mode (Don't need any of our highs being omnomed!) and turn on the shaper. Set it to Wrap mode and turn the drive up to around 55 or so. What you should have now is a nice buzzy tone, best played around C1.
The synth should look something like this.
STEP TWO: DISTORTION. Open up one of them Scream 4 Distortion units, initialize it, and route our Thor into that baby! Set the distortion type to Tube, and the Damage Control slightly up to around 65. Turn P1 to 40 and P2 to 16 to give it a nice low hum while maintaining the buzz and not being too gritty. Turn on the Body, setting it to type E. Turn the resonance all the way down, it usually doesn't work with Electro synths. Turn the scale to around 50 and the auto to 45-ish.
STEP THREE: Equalization. This part is pretty much up to the person making the synth. I like to boost the lows and mids, cutting the highs by around a half a decibel. Make sure to cut room for the drums too!
My scream and EQ setup looks like this.
STEP FOUR: Throw on a BV512 Vocoder and set it to Equalize mode. Turn it down to 8-Band (EQ settings are, again, up to you, though I tend to leave them alone in the vocoder). Take the shift knob and turn it up a few notches, just to give the higher tones some voice. after this, compress and maximize to taste, you're almost done!
My vocoder, compressor, and maximizer setup looks a little something like this.
STEP FIVE: Final step! Add a touch of reverb to it if you like, just to help it fit into the mix, and then go back up to our line mixer. Hook up a compressor the the aux. output, and turn the threshold all the way down, the ratio all the way up, the attack all the way down, and the release all the way up. Then turn the aux. send for channel one (or whatever channel you're using for the thor and effects) to around 3/4 of the way around. This is a rudimentary form of parallel compression. If you don't know what that is, then that's kinda sad.
Final touch, if you want to add some parallel compression, just hook the mixer into a compressor and throw in a Redrum. add in the normal preset (Disco Kit RDK), and hook the output from drum slot 1 into the "sidechain in" section of the compressor. Set up the drum pattern on the kick (Drum slot 1) to conform to your drumbeat in your song, and adjust the parallel comp. to taste. Just make sure to tick off "receive notes" for the Redrum in the programmer section of the combinator.
There. You're done. If you need a reference, I'll be uploading the patch in a group of Reason presets I'm releasing soonish.
No you can't have it now.
Hope I helped or whatever.
