Klayton (Celldweller) is back with the second video in our new educational series on the basic building blocks of synthesizers. In this new video, Klayton is focusing in on voltage-controlled filters (VCF) and demonstrating how they are used with some help from a Moog Music Model 15, Malekko Richter Dual Borg, Intellijel Korgasmatron II and more. VCFs are responsible for sculpting your synthesizer's sound and altering other aspects of a signal, by using common filters like Low-Pass, High-Pass, Comb, Band-Pass and Notch. Just as its name implies, these modules offer users a plethora of options for blocking some frequencies and allowing others to pass through. Learn more about VCFs and how they can affect your synth's sound by checking out our video with Klayton (Celldweller) below and stay tuned as we'll be releasing more videos in this educational series in the coming weeks.
