Used Erica Synth Graphic Resonant Filterbank

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. The Expander module (works exclusively with the Graphic Resonant Filterbank and is available separately) provides hands-on adjustment of boost and cut for all bands.
