At Superbooth 2026, Erica Synths has introduced the Resonant Filterbank, a standalone analog stereo filterbank.
The Resonant Filterbank has ten bandpass filters, with hands-on control over each bands’ boost or cut. Complex control configurations that can turn it into an unconventional multimode filter with an envelope follower and an instrument on its own, when played with various resonance settings or even an experimental sound generator for no-input mixer-like setups.
You can use it with synthesizers, drum machines, modular setups and – thanks to an analog GAIN STAGE that boosts incoming signals up to +24dB – with guitars and pretty much any other instruments.
Features:
- Analog 10-band stereo filterbank
- Filter frequencies: 29 Hz, 61 Hz, 115 Hz, 218 Hz, 411 Hz, 777

- Filter slope: 17 db/decade
- High quality film capacitors in the bandpass filters
- Manual and MIDI CC controlled bands’ boost and cut
- Configurable resonance feedback loops
- Manual and MIDI CC controlled resonance
- MIDI clock synchronization of events
- Multimode filter mode
- Spectral analyzer mode
- Dynamic spectral compressor mode
- 20 independent LFOs
- 20 independent envelope followers
- User snapshot (preset) memory with 128 slots
- Discrete and morphing snapshot change
- 6.3mm balanced stereo inputs and outputs
- Configurable footswitch input
- DIN 5 MIDI IN and MIDI OUT
- Dimensions: 25,8 x 17,6 x 7 cm (including knobs)
- Mass: 1,1 kg
Pricing and Availability:
The Erica Synths Resonant Filterbank is expected to ship May 18, 2026 priced at 660 EUR (VAT excl.).
Wish it had usb over midi, well if I am super wishing, I wish it had a plugin editor vst for full easy recall or even usb over audio like over bridge so I could just run it as an insert in my daw like I do my analog heat.
I wish this for every piece of hardware!
Is the reason why down to latency?
From what little I understand about this, if the host connection’s a midi-master that introduces latency over USB then it’s suboptimal compared to the old 5 pin din connector. Therefore adding the usb option raises the cost (extra parts & programming) for a less effective connection.
I’ve tried using Ableton as a sequencer for a bunch of hardware synths connected via USB & it wasn’t as nice as using a standalone sequencer with din cables. Computer was a MacBook Pro M2, so my processor wasn’t the issue.
If/when software latency’s resolved midi-over-usb would be amazing.
This looks incredible, 20 LFOs, 20 envelopes, feedback loops, morphing patches…
Really keen to hear this in action by regular users & reviewers. Erica’s been making some of the most interesting gear of the past few years. Might have to risk divorce blow my savings on the Hexdrums, Steampipe, Ninja Delay & this.
