Erica Synths Resonant Filterbank

The Desktop Resonant Filterbank is an analog stereo filterbank designed for studio production and live performance. With ten bandpass filters and detailed hands-on control, it can shape incoming audio in creative and unconventional ways.

The filterbank provides manual control over each band’s boost or cut, along with configurable resonance feedback loops. This makes it possible to use the unit as a multimode filter, a resonant sound-shaping instrument, or an experimental generator in no-input-style setups.

It includes an analogue gain stage that boosts incoming signals up to +24 dB, making it suitable for synthesizers, drum machines, modular systems, guitars, and many other instruments. The unit is also designed to support MIDI synchronization and control for flexible performance use.

User snapshot memory with 128 slots, discrete and morphing snapshot changes, and multiple dynamic modes make the filterbank a versatile creative tool. The aluminium enclosure matches the compact desktop format used throughout the series.
