Meska’s Filter Bunker: Erica Synths Resonant FB Gets the Rave Lab Treatment

Meska jumps straight in, introducing the Erica Synths Resonant Filter Bank as a ten-band analog filter bank with fixed frequencies, but don’t be fooled—this is no museum piece. The real magic is digital: save and load presets, tweak feedback, and step into new creative territory. You get a front panel full of knobs, buttons and encoders ready for action.

There’s a quick run through the interface—gain, resonance (bipolar for inverted feedback too), navigation encoder, and the full spread of CV inputs for total surgical control. Stereo is sorted with odd/even outputs, which means you can get wild with the stereo field and stack up some serious chaos. In short, this is a filter bank with teeth and a taste for trouble.

For the demo, Meska slams white noise into the filter bank—no polite sine waves here, just raw fodder for the beast. You can solo bands, sweep gains, and crank resonance until the whole thing howls. It’s not just about shaping sound; it’s about pushing the circuit until it begs for mercy. Watch your headphones, though—this thing will scream if you let it.

Self-oscillation isn’t some accidental side effect—it’s a feature, a weapon for those who want their filter bank to double as a mad oscillator. The feedback path gets a workout, with both standard and inverted options showcased. The result? Unpredictable, gnarly textures that sound more like a rave in an abandoned power station than a polite filter bank demo.

Meska dives deep into the different operational modes, starting with classic filter sweeps, then moving to clocked and dynamic territory. Clocked mode lets you step through bands in sync with an external clock—think Pamela’s New Workout—sampling CV values and creating animated, evolving textures. Push the clock rate high and bands start swirling in a way that’s more ‘modular fever dream’ than ‘traditional filtering’.

Dynamic mode is a bit of a spectral detective, analysing incoming signals and boosting or cutting frequencies based on thresholds. Drop in a complex VCO and the module starts sculpting wild new timbres, perfect for dark, experimental techno and brutalist sound design. There’s a play mode for morphing presets, randomisation, and even a spectral visualiser for those who want to see the mayhem as well as hear it. Some modes get a quick pass (spectral mode, we’re looking at you), but it’s clear this module isn’t short on creative routes for experimentalists.
