Erica Synths has introduced the Erica Black VCF, a dual multimode filter with CV control over cutoff and resonance.
The core of the VCF is highly stable, custom multimode VCF chip AS3320. 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.
A 16-band spectrum analyzer gives visual feedback on what happens on summing output.
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
Pricing and Availability
The Erica Black VCF is available for 350 EUR (+21% VAT for individual customers in EU without EU VAT registration number + shipping).
maybe i’m too stupid to find it … but what’s the slope on this filter?
Probably 12dB/oct if it is a state variable filter, which it seems to be since all outputs are available simultaneously.
