What is a Fixed Filter Bank? | Chaos + Control with Zlob VC F3DB

In this video, we explore the history of fixed filter banks in synthesizers (what they are, how they work), demonstrate some classic fixed filter bank concepts, and then dive into a series of patch examples exploring the Zlob Modular VC F3DB.

Zlob Modular’s VC F3DB is a filter bank for Eurorack modular synthesizers. But it’s much more than just that as well; while it can produce the clean, dry, nasal tones you might expect from a classic Moog or Buchla filter bank, it is designed to leverage feedback, clipping, and per-band envelope followers, allowing it to act as a chaotic sound source, spectral decoder, and intense distortion.
