How do I sync the LFO to get that wobble bass?

[uBUNTU]

Hey,

I know how to use the ES1 to create the wah wah/wobble sound found in dubstep productions by adjusting the cutoff. I figured out how to do that just fine, but now I am trying to take it to the next level. Say the tempo of my track is 128BPM- and I create the wah wah/wobble sound on the ES1. I want my ES1 sound to oscillate 16th notes at 128BPM. How can I get it to that exact tempo? I hear a lot of producers do this, and also hear them musically speed up/ slow down the waves for added effect.
Here's a decent example of what I'm talking about. For example from 2:59-3:00 joel oscillates the waves to 16th notes then oscillates them to triplets at the end of the phrase. I wanna be able to do stuff like that.

All you have to do is set the LFO to 16th notes, and then you can automate it to whatever you want. Turn the 'rate' setting counter clockwise and you'll satrt to see the 'sync' options, which will sync the LFO rate to the tempo of your project, then you can select the note length of the LFO rate, for example the 16th value you mention.
