Erica Synths Resonant Filterbank: Advanced Stereo Spectral Shaping

The Erica Synths Resonant Filterbank brings high-end analog filterbank processing to both studio producers and live performers who want exceptional control over their sound. Ten fixed-frequency bandpass filters are arranged in stereo, each offering dedicated fader manipulation for precise tone shaping. What distinguishes this model is its digitally controlled analog path, versatile modulation, and smooth integration with modular or desktop systems. Sound designers can discover entirely new sonic textures, using the filterbank for everything from gentle EQ to dramatic transformation.

Exceptional Features for Creative Sound Design

Combining analog filtering with deep digital control, it allows for user snapshot memory (up to 128 presets) and smooth morphing between settings—perfect for creative performance. Configurable resonance feedback loops, spectral analyzer mode, and dynamic spectral compression let producers push the boundaries of mix and performance. Built-in tools like these support innovative audio manipulation in both live and studio environments.

Powerful Modulation & Connectivity

Animate each filter band using 20 LFOs and 20 envelope followers for evolving, complex modulation. Balanced 6.3mm stereo inputs and outputs provide pristine integration with professional rigs, while MIDI control and footswitch input give additional flexibility for performers seeking responsive setup options.

• Filter Frequencies: 29 Hz, 61 Hz, 115 Hz, 218 Hz, 411 Hz, 777 Hz, 1.5 kHz, 2.8 kHz, 5.2 kHz, 11 kHz — covers the full audio spectrum for comprehensive tone sculpting
• Gain Stage: +24 dB — boosts any input for compatibility with modular, guitar, or line-level sources
• Each of the 20 LFOs and 20 envelope followers can be routed to individual filter bands for advanced animation and movement within a mix.

Studio and Performance-Ready Architecture

With its solid aluminum chassis and compact desktop format, this instrument suits both transport and durability requirements. Full MIDI implementation enables parameter control, clock sync, and DAW or external sequencer integration. Footswitch input allows real-time manipulation during performance, fitting a variety of workflows and creative needs.

• Preset Memory: 128 slots — recall or morph between sound settings instantly
• Filter Slope: 17 dB/decade — classic analog response and character
• Portable yet robust, it measures 258 x 176 x 70 mm and weighs 1.1 kg, ideal for mobile producers.

Multiple Modes for Expansive Tonal Exploration

Aside from filterbank operation, this model can function as a multimode filter, dynamic spectral compressor, or spectral analyzer, making it useful for traditional filtering, experimental sound creation, or surgical spectral processing. Flexible modulation routing multiplies the creative options for producers and sound designers.

• Manual and MIDI CC control over all bands and resonance for ultimate flexibility
• Band enable/disable for selective filtering and unique effects
• Balanced stereo I/O and MIDI DIN for full professional integration
