OK ill show you now how to do a wobble bass in the most simple form on a VST called massive. Check the picture below:
NOW The ‘Pink’ Section is called the oscillator. this is essentially what sound it is going to make Such as: Saw wave or smooth square etc. This has been taken down to -12 which means it is an octave below middle C. There is a fader on the right of the box this is the option of routing the sound to a filter (In this case it is all the way up to filter 1)
THE FILTER: (outlined in Turquoise) This is basically the controlling section of the noise. so the Cutoff is how much of the sound you want to pass through. The resonance basically just amplifies the sound. In this case we have a low pass filter selected (You can select which one you want by clicking on the drop down menu at the top of the box) Again you’ll see the fader at the side which means you can route it to another filter again but for this exercise we haven’t so we put it up to just allow it through filter one. You’ll notice on the cutoff that there is a green number at the bottom of the cutoff knob this is how we have Routed The LFO. (you do this by clicking where the red arrow is pointing and dragging it to the box where the green number is in).
THE LFO: Is a Low Frequency Oscillator, This modulates the audio signals coming through and it is a pulsing rythym unlike the ocsillator which is just an audible tone. You’ll notice that on the left side is a fraction that says 1/16 now this is how you can changes the speed of the pulsating rythym (Wobble). You change it by dragging the box where the ’16’ is up and down till you gain the rythym that you require. When you drag the cross section to the filter you drag the green number up and down to gain a line around the knob, this is basically controlling the LFO within the filter.
Now you should have a Wobble Bass line happening. If not please don’t hesitate to ask questions.
