Roland System 521

The 521 Dual VCF (Voltage Controlled Filter) consists of two separate low pass filters that allow you to manipulate the sound character of external audio signals.

Each of the filters has dedicated controls for controlling the cutoff frequency and resonance as well as a preset high pass filter with two switchable cutoff frequency values. The audio and CV input mixers on both channels allow you to blend multiple audio signals and modulation sources.
