Erica Synths Black Dual VCF is a dual multimode filter with CV control over cutoff and resonance for serious modular patches.
Features Two identical multimode VCFs Simultaneous HP, BP and LP outputs Summing output CV control over Cutoff and Resonance CV level attenuverters Link switch for controlling both VCFs with one cutoff or resonance knob 16 band spectrum analyser Skiff-friendly design At the core of this VCF is a highly stable, custom multimode VCF chip AS3320 (produced in Riga, btw). This module can be used as two independent VCFs with simultaneous HP, BP and LP outputs, controls can be linked to stereo application and both VCFs can be chained in series or parallel to the summing output for ultimate modulations. Bonus feature – the 16 band spectrum analyser gives you visual feedback on what happens on summing output.
