Dual multimode VCF with spectrum analyzer
Dual multimode filter with CV control over cutoff and resonance for serious modular patches. It can be used as two independent VCFs with simultaneous HP, BP and LP outputs, controls can be linked for stereo application and both VCFs can be chained in series or parallel to the summing output for ultimate modulations. Bonus feature – 16 band spectrum analyser – gives visual feedback on what happens on summing output.
