Erica Synths Graphic Resonant Filterbank Eurorack Filter Effect Module

The Graphic Resonant Filterbank (FB) is a ten-band analogue filterbank with digital control over each bands’ boost or cut. Each band can be controlled individually via CV or manually, while complex control configurations turn the filterbank into an unconventional multimode filter and even an instrument in its own right when played with various resonance settings.

This new architecture gives an unprecedented level of control for shaping sounds with the possibility of saving presets, randomizing band levels, applying clocked modulations and even allowing for the module to act as an unconventional multimode filter.

The CV inputs for all bands and the clock input allow for integrating the Graphic Resonant Filterbank into any Eurorack system. Whether you’re looking for a delicate sound design tool for balancing out the frequencies in your patch to sound just right or an experimental scream machine that can mangle any sound source into uncharted territory, the module does it all – a versatile secret weapon for your rack!
