A deep dive with the Erica Synths Graphic Resonant Filterbank!

The Erica Synths Graphic Resonant Filterbank (FB) is a modern take on a cult classic of modular synthesis: the Serge Resonant EQ. The original design dates back to the late 70s, and it’s pretty simple - a bank of 10 manually controlled filter bands that can process sound sources in subtle or extreme ways. It can self-oscillate for complex drones, or you can ping it with pulses to create organic-sounding percussion. For the Graphic Resonant Filterbank, Erica Synths took this basic idea but added a bunch of digital control, bringing it right up to date and massively expanding the range of potential applications.

This video is sponsored by Erica Synths, and in it I build some patches that explore what the Graphic Resonant Filterbank can do, from complex spectral animation to pinging and feedback.
