Erica Synths has opened pre-orders for the Desktop Resonant Filterbank, a new analog stereo filterbank built for studio processing, live performance, and experimental routing. It is priced at €660 before VAT, with shipping estimated for May 18, 2026.

The main idea is simple: ten analog bandpass filters, each with hands-on boost and cut control, placed inside a desktop unit with MIDI control, snapshot memory, feedback options, stereo panning, and enough modulation to push it far beyond static EQ-style filtering. It can process synths, drum machines, modular systems, guitars, and other instruments, helped by an analog gain stage that can boost incoming signals up to +24 dB.

That input gain detail is important because the Resonant Filterbank does not appear to be built only for clean studio correction. It is a tone-shaping and performance unit that can turn familiar sources into something less predictable. A synth line can become narrower, harsher, wider, or more animated. A drum machine can be pulled into resonant peaks and moving frequency bands.

A guitar can hit the filters at a level high enough to feel closer to a synthesizer chain than to a standard pedal setup.

Ten Analog Filters With Hands-On Control

The Resonant Filterbank uses 10 bandpass filters at fixed frequencies: 29 Hz, 61 Hz, 115 Hz, 218 Hz, 411 Hz, 777 Hz, 1.5 kHz, 2.8 kHz, 5.2 kHz, and 11 kHz. Each band can be boosted or cut manually, with MIDI CC control available across parameters.

That gives the unit a clear studio role. It can shape a stereo source with broad frequency movement, carve percussion, emphasize specific resonant areas, or turn a static loop into something that changes across a performance. The filter slope is listed at 17 dB per decade, and Erica Synths is using film capacitors in the bandpass filters.

The more interesting side comes from the feedback architecture. Configurable resonance feedback loops and MIDI-controllable resonance can push the device toward multimode filter behavior, animated frequency movement, or no-input mixer-style sound generation.

That puts it in the same general conversation as sound design tools that can process external audio and act as instruments in their own right.

A Filterbank Built For Live Control

Erica Synths also packed the unit with performance features. The Resonant Filterbank includes 20 independent LFOs, 20 independent envelope followers, MIDI clock synchronization, spectral analyzer mode, dynamic spectral compressor mode, and 128 user snapshot slots.

The snapshot system may end up being one of the most useful parts of the design. Users can store settings, recall them during a set, and move between them with discrete or morphing changes. That gives live performers a way to move through filter states without needing to manually reset every band between sections.

The hardware side stays practical as well. The unit includes balanced 6.3 mm stereo inputs and outputs, DIN 5 MIDI In and Out, a configurable footswitch input, and a compact aluminum desktop case measuring 25.8 x 17.6 x 7 cm, including knobs.

At €660 before VAT, the Resonant Filterbank sits in a focused lane: analog stereo filtering for producers and performers who want tactile control, MIDI automation, modulation, feedback, and preset recall in one desktop processor. For synths, drum machines, modular rigs, guitars, and live electronic setups, it looks like one of Erica Synths’ more flexible processing tools heading into summer.
