The Elka Synthex was manufactured in Italy by the organ company Elka from 1981 to 1985. Despite its relatively short production run, it left an indelible mark on electronic music. Jean-Michel Jarre used it extensively on albums like Rendez-vous and Revolutions, most famously for the laser harp sound. Stevie Wonder was another notable user, and Keith Emerson had one in his arsenal. The Synthex was particularly noted for its DCO stability (rare in the early 1980s), powerful sound, and distinctive chorus.
Black Corporation released Xerxes as their third major polysynth, following Deckard's Dream and Kijimi. The MK2 version refined the design with improved VCAs for better dynamic response, professional balanced outputs, and the increasingly important USB audio connectivity. The dark panel option gives it a modern aesthetic while the sound remains authentically vintage-inspired.
Original Synthex units in good condition now command $15,000-$30,000 or more, making Black Corporation's recreation the only realistic way for most musicians to access this legendary sound. The DIY kit option continues the company's mission of making boutique analog polyphonic synthesis accessible to builders.
