The SCREAMING Filter: How Herman Gillis Created the Sherman Filterbank

video upload by Anthony Marinelli Music

"Meet Herman Gillis, the inventor of the Sherman Filterbank, one of the most aggressive and unique filters in electronic music history! In this exclusive interview, Herman reveals how he employed Switched-Capacitor Filter (SCF) technology to create an analog powerhouse that shaped the sound of artists like The Orb, David Bowie, Human League, Ziggy Marley, and more...

What makes the Sherman Filterbank so special? Herman takes us through the evolution of his designs, from his teenage years building guitar pedals and drum machines to his legendary Filterbank 1, Quad Modular Filter, Filterbank Compact, and the latest 500 series module, the Rodec/Sherman Minirestyler.

I’ll be performing on a Minimoog and laying down grooves with a TR-909 drum machine throughout the video—bringing Herman’s filter madness to life with some face-melting musical examples! You won’t just hear us talk about this screaming filter—you’ll experience it in all its glorious, growling, and gut-punching sound!

If you’re into synths, sound design, and legendary instruments, this deep dive into one of the most extreme filters ever built is a must-watch!"

"These original units did not have MIDI.

According to the Sherman website just 40 of these Belgian beasts were made. No MIDI and the back “panel” is plastic plumbing pipe. No frills – all thrills.

Serial number: 31 – signed on the back by Herman!

In terms of functionality and sound it is obviously closer to the early Filterbank 1."

"Two identical Sherman Filterbank 2 devices in a flat 19" housing that can also simply lie on the table. All inputs and outputs are located on the front panel, which makes countless connections between the two devices easy, but above all with other tabletop devices. Via 'link' sockets, the two filters can be linked and played in parallel. Like the simple rack version, both LFOs also have a waveform output.

Technically and visually great condition - only near the logo there is a subtle scratch."
