Sputnik WCRS: Fluctuating random

(electronic humming) - [Instructor] Alright, let's play around with these random voltages. I'm going to switch to my blue cables since that's what I use to trace modulator voltages throughout my system. Unlike an LFO, which is very periodic, we'll just throw one up on the screen here real quick so you can see it. There's the typical LFO. The fluctuating random voltages wander around very slowly or quickly depending on how you have them set. You'll see this based around maybe two volts, maybe three volts. It's all above the zero line, and the faster I turn it up, the wider the swing it also takes. You can also slow it way down. Changes levels very gradually. Or pick this over here in the middle, which is a happy difference between some changes and a little bit more of a range. Since this is above zero, it's going to raise anything you plug it into like a filter cut-off. If you wanted to, you could run something like this, let me get a longer cable here, into a mixer stage that also had…
