Modulate The Madness *in stereo*


Audio-reactive modulation? Check. FM from your own signal? Absolutely. CV control? Of course. The Ministyler lets you modulate filter frequency and mode using either CV or the incoming audio itself. 

Add auto-modulated pulses to your mix, trigger filter movements with a beat, or let your signal twist itself into new shapes. It's not just a filter — it’s an evolving, unpredictable performance tool that breathes life into your sound.

Sherman Inside

The legendary Sherman filter circuit lets you morph smoothly between low-pass, band-pass, and high-pass modes, with switchable 12dB or 24dB slopes. Sweep, sculpt, or send your signal spiraling into oblivion. 

It’s the same wild tone-shaping power that made the Filterbank a classic — now reimagined for the modular era. And yes — the resonance self-oscillates, giving you screaming peaks, harmonic overtones, or even a playable tone source when pushed.

Shape, Break, Blend


At the heart of the Ministyler is a powerful drive stage with makeup gain and a dry/wet blend knob that lets you dial in everything from subtle warmth to full-blown analog destruction. 

Slam it for gritty textures, then pull it back with precision to find the perfect sweet spot. Whether you're thickening drums, heating up a bassline, or adding edge to a vocal, this circuit is your weapon of choice for controlled chaos.
