Twist familiar sounds into shifting, animated spectra and turn any signal into a playable instrument in its own right. The Erica Synths Resonant Filterbank is a desktop analog stereo filterbank designed for deep sonic sculpting in the studio and on stage, with digital control that keeps your wildest ideas recallable and tightly under control.
At its core are ten analog bandpass filters arranged across the stereo field, each with dedicated boost and cut and powerful resonance options that invite everything from subtle tone-shaping to screaming, feedback-rich textures. Complex control configurations transform this filterbank into an unconventional multimode filter, dynamic EQ, and envelope-following processor, capable of spectral compression, morphing sweeps, clocked modulation and no‑input, mixer-style feedback experiments. An analog gain stage delivering up to +24 dB means you can feed it synths, drum machines, modular signals, guitars or almost any other instrument and discover entirely new characters in sources you thought you knew inside out.
Twenty independent LFOs and twenty envelope followers offer animated, per-band modulation, all under full MIDI control so you can record and automate every parameter from your DAW and store user snapshots as presets for instant recall in performance. Balanced stereo inputs and outputs, a configurable footswitch input and DIN MIDI in and out make it easy to drop the Resonant Filterbank into existing setups, while the compact, sleek aluminium desktop chassis matches Erica’s other standalone units and is built to live wherever you need a serious spectral shaping weapon.
