VCF-74 MK2

The VCF-74 is a 14hp Eurorack analog voltage controlled filter, inspired by the diode-ring design of the 1970’s Mini-Korg traveler circuit. The filter is a cascaded (series) arrangement with HP feeding into the LP. It includes CVs to control cut-off and resonance per filter section. A boost switch allows for the HP to drive the LP in a way that provides warm saturation. Built in attenuators for level of: input; output; CV to HP; and CV to LP.

Features and controls:

  • Simultaneous High-pass and Low-pass discrete filtering
  • CV to cut-off (per filter, independent)
  • CV to resonance (per filter, independent)
  • Built-in attenuators (for CV to cut-off, Input level, Output level)
  • Boost switch (allows HP to saturate LP)

MK2 CHANGES (difference from MK1) LIST:

  • The faceplate will look exactly the same, except the addition of “MK2” nomenclature screen printed
  • The audio signal path will have slightly lower frequency response as a result of component value changes
  • The audio signal path will now use fewer coupling capacitors (more direct-coupled circuits means better overall performance including less slewing)

The AWM-3 is an all analog, real-time, complex wave-shaping (triple wave-folder) 3-channel mixer module with added features of compression and multiple mix modes including matrix mixes. The combination of multiple access points (outputs of various mixes), wave-folding, and compression allow for an extremely wide array of signal processing, including complex choruslike sounds.
