The ‘Heart of Subtractive Synthesis’: The Moog Ladder Filter, Explained

Moog Music has a new video out today on The Moog Ladder Filter, the patent for which Bob Moog is being inducted into the National Inventors’ Hall of Fame.

Rick Shaich, Moog Hardware Engineer, narrates the video and explains the Ladder Filter’s important distinction of being “voltage controllable… It’s really the heart of subtractive synthesis, which is ‘The Moog Sound.'”

It’s a great explanation of what a Ladder Filter is/does, and the role it has played in modern music.
