Erica Synths Graphic Resonant Filterbank

Leveraging the power of a robust digital control over analog circuitry, the Erica Synths Graphic Resonant Filterbank is a highly musical array of filters for dynamically shaping—or generating—sounds. Drawing inspiration from the classic Resonant Equalizer found in Serge modular synthesizers, Erica's take on this beloved design provides unprecedented levels of control over ten filtering bands. Like the original, most bands are tuned apart in musical intervals of a major 7th—avoiding octaves that would un-evenly emphasize harmonics of specific notes.

With its powerful digitally-controlled architecture, the Graphic Resonant Filterbank gives you an abundance of options to build out and store numerous patches in digital memory. Modulate each band with external control voltages, change the mode of each band to variety of different filter types, and patch in an external clock signal to synchronize modulations or step through different preset snapshots. Add a 21st century take on the beloved RESEQ to your rack with Erica's Graphic Resonant Faderbank.
