Vintage Synth Lab VCF-74 Eurorack (Korg Minikorg 700s) Filter Demo


Published on Mar 29, 2017 mylarmelodies

"Being a demo of the very vintage VCF-74, inspired by the Korg Minikorg 700s 'Traveler' dual filter. A 6dB HP & 12dB LP in series, with wonderful natural compression, warm drive characteristics, and a ton of personality. More info & dealers here: http://www.vintagesynthlab.com/eurorack/vcf74

More info from the folks at VSL:

"The VCF-74 is a 14HP voltage controlled filter in Eurorack format. VCF-74 features a dual analogue high-pass and low-pass filter, cascaded (series, from HP - LP). The discrete diode filter circuit is inspired by the 1970s Univox Mini-Korg synthesizer's "Traveler" filter section which provides warm, organic sound to your modular system. However, this design was not only adapted for Eurorack, but is feature enhanced for a wide array of possible filter characteristics.

A stage boost switch allows you to drive the 2nd filter section (Low-Pass) with a +5.3dB signal boost from the High-Pass output signal creating a warm saturation and varied resonance to signal ratio/dynamics. Independent manual resonance controls per filter section allows you to fine-tune a wide variety of focused sound. Input and Output level controls allow you to optimize dynamic range, including how hard you drive the filter--which drastically changes the dynamic interplay between signal and harmonic resonance. Both High-Pass and Low-Pass circuits have independent cutoff controls. Independent CV inputs for cutoff and resonance of each filter section, and attenuation/gain for CV to cutoff provide superior control over filter behavior. The VCF-74 can be set up as a Low-Pass, High-Pass, or Band-Pass filter. Width of the Band-Pass can be adjusted by simply dialing in the offset controls appropriately."
