Welcome our newest compact filter GELATO! A diode-ladder low-pass filter packed into just 4HP, Gelato brings smooth, creamy filtering with classic analog flavor. It features two CV inputs for expressive modulation, plus rear trimmers to dial in the base cutoff and resonance response just how you like it. And yes — that’s a glowing ice cream cone on the panel, surrounded by stars. Because why not sound good and look tasty?
