Erica SynthsGraphic Resonant FB 10-Band Filterbank

Independent shopping perspective
The Korena take
Graphic Resonant FB puts ten analog band-pass filters under manual and voltage control in a 20HP Eurorack module. Each band can be boosted or cut, while configurable CV inputs and voltage-controlled resonance make the filterbank part of an active patch rather than a fixed EQ setting. Store up to 128 presets, synchronize changes from the clock input, and route from the main, even, or odd outputs. It also includes multimode filtering, spectral analyzer, dynamic spectral compressor, and pattern-change modes.
Strong match
Who this is for
- Building CV-controlled spectral changes across ten filter bands in a Eurorack patch.
- Recalling stored filter configurations during clock-synchronized modular performance or studio work.
- Exploring resonance-feedback configurations alongside manual control of individual filter bands.
