Filters based on IR3109 had several drawbacks, including a volume drop when the resonance is increased so we added a volume drop compensation as well as a built-in VCA for more versatility in compact setups. Additionally, 1V\/oct tuning is implemented so you can use this module for perfect VCF keyboard tracking and also as a VCO.\u003cbr\u003e FEATURES:\u003cbr\u003e 24dB\/oct lowpass VCF\u003cbr\u003e Volume drop compensation\u003cbr\u003e Built-in VCA\u003cbr\u003e Cutoff level attenuverter\u003cbr\u003e 1V\/oct tracking\u003c\/p\u003e","brand":"ERICA SYNTHS","offers":[{"title":"Default Title","offer_id":41908108525741,"sku":"erica_synths_black_3109_vcf_vca","price":209.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0606\/3449\/7197\/products\/black_vcf_vca_3109.jpg?v=1665114962","url":"https:\/\/www.detroitmodular.live\/products\/erica-synths-black-3109-vcf-vca","provider":"Detroit Modular","version":"1.0","type":"link"}
