The 521 Dual VCF (voltage controlled filter) module features two separate low pass filters for modifying the timbre of audio sources. Each filter has its own dedicated controls for frequency cutoff, resonance, and a fixed high pass filter with two switchable cutoff points. Audio and CV input mixers on each channel allow the blending of multiple audio signals and modulation sources.

Based on the legendary SYSTEM-700 and SYSTEM-100M, the SYSTEM-500 introduces a range of fully analog Eurorack modules inspired by two of the most revered electronic instruments of all time. They include classic Roland oscillators, filters, envelopes and effects that can easily integrate into any existing Eurorack setup or form the centerpiece of a new modular system. Designed and built in the USA, each SYSTEM-500 module is made to exacting standards with top-quality components and extreme attention to detail. They sound as good as they look with classic character and modern reliability. And they're surprisingly affordable, turning the fantasy of finally owning a Roland modular synthesizer into reality.
