Both frequency cutoff and resonance (Q) are voltage controllable. It offers a simoultaneous low-pass and band-pass output.\n\n![Polykit VCF-3350-8](vcf-3350-8.png)\n\n## References\n\nhttps://electricdruid.net/datasheets/AS3350.pdf\n\nhttp://www.synfo.nl/datasheets/CEM3350.pdf\n\nhttp://www.electricdruid.net/datasheets/EMEngCEM3350.pdf\n\nhttps://archive.org/details/sm_Synthesource_Issue_2\n\nhttp://www.digisound80.co.uk/digisound/modules/80-16.htm\n\nhttps://kg.kg/cem3350-eurorack-filter/\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpolykit%2Fvcf-3350-8","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fpolykit%2Fvcf-3350-8","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fpolykit%2Fvcf-3350-8/lists"}
