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.

User Manual

EXPANDER-------

Expander module provides hands-on adjustment over all bands’ boost and cut without the need to select bands via pushbuttons on the Graphic Resonant Filterbank module. This makes sound design with the Graphic Resonant Filterbank much easier.

NB! The Expander works exclusively with the Graphic Resonant Filterbank!
