Today we will be checking out LFOs in a little bit more detail. LFO stands for Low Filter Oscillator. LFOs are my favorite sources to modulate synth parameters. You can use an LFO to make a simple wobbling effect in a sound, or a slow morphing feel. LFO is a common term used in electronic music production because they are so often used. Lets take a closer look at how the LFO works.

An LFO has a shape. It can be simple like a triangle or sine wave, or it can be more complex with different peaks, valleys and plateaus. You will want to use different shapes to achieve different effects. A simple sine wave thrown onto a low pass filter can give a cool continuous wobbling sound this is something you hear in dubstep all the time. Some good oscillator additive synthesis with a simple sine wave LFO and some distortion over it can create a really gnarly effect.


Once you select the shape of your LFO, you can assign it to the various parameters of your synth. Filters are the most commonly chosen destination for an LFO, but you can throw them on things like wavetable position, phase and pan. You can assign an LFO to pretty much any parameter, and you will find that you have your favorites as you learn more about your main synth.
