Chromatron

The Chromatron is the culmination of a decade spent fine-tuning and reinventing the state variable filter circuit. This optically-controlled analog filter allows you to effortlessly toggle between envelope control and manual operation using an expression pedal at the press of a button. Featuring a unique envelope detector, it delivers a musical filter response that covers a wide spectrum of sounds, from classic quack to futuristic synth psychedelia.
