Blue Lantern Asteroid Operator VCF

The Blue Lantern Asteroid Operator VCF is capable of a vast array of desirable tones and waveshaping sounds. The module is capable of standard state variable low-pass, high-pass, and band-pass filtering, as well as switchable state variable low-pass, high-pass, and band-pass filtering. At the core of the Asteroid Operator are two v2164 IC chips that comprise its eight filter outputs. There’s also an internal 5V regulation routed to the cutoff, resonance, and VCA knobs—the idea here being stabilization of the voltage swings.

Asteroid Operator VCF Features

  • 8 filter output combinations
  • Standard state variable bp, hp and lp filtering (for "classic" synth sounds)
  • State variable bp, hp and lp filtering by use of the switches
  • Dedicated linear VCA
  • Can act as a sine wave generator that can be pushed into trapezoidal shapes to sound 'tube' like
  • Has an on board sub harmonic generator with two sub frequencies you can mix to create fat chord sounds
  • 2 bi-polar modulation inputs, FM has AC/DC/Over switch, Mod has flip/flop & AC/DC switch. FM has buffered output
  • 2 octave sub generator
  • freely patchable linear vca based on the v2164 ic
  • 2 direct cv inputs
  • 8 different filter combinations: ranging from bp/hp/lp & phaser, all available simultaneously
  • 4 stage diode limiter switch, with selection of internal capacitor
  • 2 stage diode limiter switch
  • A 'pluck' hack switch
  • The cutoff range can be adjusted (500k), 
  • 1v/oct can be calibrated (1k), 
  • resonance range can be adjusted (100k) and 
  • LP floss level output can be adjusted


  • Eurorack Module
  • +12V: 108 mA current draw
  • -12V: 96 mA current draw
  • 23 HP Wide
  • Roughly 4 cm deep
