Product Details

C4RBN (pronounced "Carbon") is a 4/2-Pole State Variable Filter with input saturation, output wavefolding, and more.  It features a wide range of character from nice and clean filter sounds to screaming, squelchy, acidic mayhem.  

C4RBN builds on WMD’s history with state-variable filters adding interface refinements and improved warm environment stability for live performance and beyond. A novel input saturation circuit plus the output wavefolder from WMD’s classic SYNCHRODYNE filter pair together to push the timbral flexibility to the next level. C4RBN is the building block to life in your eurorack.
