Random Source began life out of an affinity for the Serge Modular Music System and the desire to make the experience therein more intuitive and widely available. They produce 4U modules in the spirit of the original Serge modules, albeit with divided panels for consistent aesthetics and easy installation. More recently the company has branched out into the realm of eurorack, offering DIY kits and prebuilt modules of old Serge favorites including the acclaimed Variable Q VCF, Wave Multipliers, and the New Timbral Oscillator.
