Earlier this year when we started working with Klayton (Celldweller), we knew we wanted to collaborate on some educational videos that would help those new to modular synthesizers understand the basics behind each type of module. In the first installment of this series, Klayton uses a Moog Model 15 to discuss the purpose of VCOs (Voltage-Controlled Oscillators) and demonstrate the significance of each type of wave. At a synthesizer's core, the oscillator is a key figure, as it's the component that allows the system to create sound. This circuit produces the electronic signal that is fed through the rest of your system and manipulated by using other pieces of modular synth gear. While building a synth requires at least one oscillator, there is no limit to how many you can add to your build-out. Having a variety of oscillators offers multiple choices in voicing, giving users the ability to create one-of-a-kind sounds by mixing a combination of waveforms. Gain more insight into the world of VCOs by checking out the video with Klayton (Celldweller) below and stay tuned as we'll be releasing more videos in this educational series very shortly.
