Based on the classic SYSTEM-100M modular synthesizer, the SYSTEM-500 is a fully analog recreation of one of the most revered electronic instruments of all time. Newly designed in Eurorack format, the SYSTEM-500 delivers the classic character and functionality of the original with the advantages of a modern instrument. Built in the USA and assembled in Japan, the SYSTEM-500 is made to exacting standards with top-quality components and solid controls. And it’s surprisingly affordable, turning the fantasy of finally owning this legendary instrument into reality.The 512 Dual VCO (voltage controlled oscillator) is a single module consisting of two voltage controlled oscillators. Each independent VCO produces frequencies across a wide range with 1V/octave tracking and dedicated pulse, triangle, and saw wave outputs. Variable pulse width is available via panel control or CV modulation. Each oscillator’s frequency can also be synchronized to the other in weak or strong modes to achieve a unique “sync” sound.
