In this tutorial I will show you how to make Skrillex style growling sound using Sytrus FM synthesizer. I learned this tip from a fellow FL user called Seamless so all credits go to him and I really recommend checking out SeamlessR’s Youtube channel for more really awesome FL Studio tips! Also, go visit his SoundCloud page for his music and remember to check his Facebook and Twitter pages as well.
Alright. Here’s a preview of this sound:
To re-create this, first open the Sytrus and select the “Default” patch to start from clean.
The central of the Sytrus synthesis engine are the six oscillators which are called ‘Operators’ (OP1, OP2, etc). Each operator can produce sound of it’s own, but they can also be used to modulate other operators. In the ‘Default’ patch, Operator 1 module produces a pure sine wave and in the modulation matrix, it’s output is sent straight to the main output mix at full volume (100%).
Next, make the Operator 2 modulate the Operator 1. The modulations (amongst operator send levels and other things) are set in the modulation matrix. To make the Operator 2 modulate Operator 1, turn the knob in the row 1 (indicates the row of the Operator 1), column 2 (indicates the Operator 2) to all the way to right. (Middle is the neutral position.)
I suggest you use lower pitch notes to play this sound because otherwise, it’s going to sound like Mickey Mouse growling.
Ok. As the Operator 2 is modulating the Operator 1 now, alter the shape of the oscillator (in the Operator 2) to modify the sound. Set the shape to 22%.
Each operator has also oscillator harmonics editor function available (OSC tab). You can edit in total of 128 different harmonics to add more variation to the sound of your patch. Now, raise the harmonic 32 magnitude to around 44%.
Next step is to map the modulation to a controller in Operator 1 articulation section so go to the OP 1 tab and set the editor target to MOD (input modulation). Under this tab, you can define the amount of ‘influence’ other operators as modulators can have on this current operator.
In the articulation section, you can apply an envelope, LFO, map keys and controllers etc to a predefined properties. In this case, our property is MOD and we are going to map it to MOD X just by selecting it (MOD X is the controller that can be moved horizontally in the Main module).
Next, set the min and max values for the MOD X controller. This way you can define how much of modulation happens when the MOD X controller is turned on it’s minimum value and maximum value. Set the point 1/2 to 0%. This means when you turn the MOD X knob all to left, no modulation is applied to Operator 1. Set the point 2/2 to 100%. When you turn the MOD X controller all the way to right, the modulation is applied at maximum level.
Now, in the Main module, tweak the MOD X controller between the min and max values and listen what happens:
This is basically the foundation of this whole sound. Next, apply a little more color to the sound by letting the Operator 3 to modulate the Operator 1 as well: in the modulation matrix, tweak the knob in the row 1, column 3 to -25%.
In the Operator 3, set the base pitch (multiplication) to 6, oscillator shape to 26% and in under the harmonic editor (OSC) harmonic 32 to 48% and harmonic 64 to 42%.
Next, assign the Sytrus to a free mixer track and load a Fruity Parametric EQ 2 to it’s effect slot and boost like this:
That’s basically it. Try using more operators for modulating for some very interesting results and experiment with the modulating, shape and harmonic values.
