Description
Learn the purpose for the 8vert module
We have already learned that oscillators create waveform. There are times in out sound design when we will want to 'invert' one of these waves. 8vert lets us to do this. 8very provides us with eight inputs and outputs and a dial to vary the degree of inversion.
What is waveform inversion
Every wave produced by an oscillator has a frequency, amplitude and shape. The amplitude refers to the distance the wave travels from the centre line during its cycle in both a negative and positive direction. Inversion takes that amplitude value and multiplies it by -1. The result is that it flips the waveform 180-degrees.
In the video tutorial I use two VCOs to produce two sine waves, each at the same frequency and amplitude. When I invert one of these we can see on the scope that it flips 180-degrees. When listening to both sine waves at the same time at the point of inversion they cancel each other out and we hear nothing!!
How to use LFO as a clock
In the video tutorial I use two VCOs to produce to separate sine waves. When we put them on the Scope they are not perfectly lined up and when we listen to one inverted there is not much change to the sound.
I use one LFO as a 'clock' to sync both VCOs. This forces both VCO to start their sine waves at exactly the same moment in time. The result is two perfectly synced sine waves. When we invert one then cancel each other out and we hear silence.
VCV Rack is an open source application, which means that it is free for everyone to use. Please consider going to the developers' website and show your support for the project - http://www.vcvrack.com
I hope you enjoy this tutorial. If you have any specific questions for me feel free to leave it in the comments of this post and I will do my best to get back to you with an answer.

@buckydurddle I always find your tutorials interesting. Though most of the words and instruments seems strange to me and I have to do vital research to find out their meaning and use. My interest in knowing about this stuff increases by the day and I really wish I was disposed to those equipments to carry out the tutorials on my own. However, I will keep reading and learning theorically about it. The knowledge can come handy some day.
Thanks for the constant update.
