Roland System-500 512 DUAL VCO

Roland System-500  512 DUAL VCO

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.
