Vult DSP’s Freak Firmware Release v2.2

Time to update your Freak Manifold Filter filter! Freak is an analog filter containing more than 12 different filter circuits. This filter has the power of simulating more than 11 Analog Filters plus 1 distortion. Every model was meticulously developed to capture the soul of the original circuit and simulate it in real-time inside this 12 HP device.

  • Fixes instabilities in Tangents-XX
  • Fixes slowdown of the module that occurs in some edge cases
  • Improves the Notch mode of Ferox

  • Tangents: Steiner-Parker filter (three variations, LP, HP, BP).
  • Lateralus: Ladder filter (6, 12, 8 and 24dB options)
  • Nurage: Low pass gate/Borg filter 
  • Ferox: CMOS filter (LP, HP, BP, Notch)
