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.

The SYSTEM-500
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 for modern performance and recording conventions, 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.

Classic System, New Format
The SYSTEM-500 consists of Eurorack format modules that you can mix and match in any combination to create the ultimate Roland modular synthesizer. Each module is completely analog and has been designed for maximum compatibility with the world of contemporary synthesizer and effects modules. The SYSTEM-500 is a compact, powerful system that opens up vast possibilities for sound design and musical exploration.
