Voltage Controlled Audio Feedback Module

Dark Matter is a high energy sound processor and signal generator that unleashes the crazy raw power of audio feedback into your eurorack system. It’s inspired by “no input” mixer feedback techniques that explore the complex natural behaviors of amplifier circuits pushed beyond their limits. Dark Matter brings this behavior to the modular synth, adds voltage control to everything, plus tons of patching options and a big ol’ bag of tricks for making feedback a truly playable effect!

  • DRIVE - Input VCA with gain and soft clipping with Hyper Drive switch for extra punch

  • TONE - 2 band equaliser with voltage controlled bass and treble boost/overdrive

  • DYNAMICS - Envelope follower creates 0-5v envelopes generated by INPUT signal and normalled to FBK CV and X-FADE CV inputs

    Low and High decay time switch

    Input pre or post DRIVE switch

    Envelope monitor LED

  • FEEDBACK - Voltage controlled feedback!

    High frequency “warning” LED

    External feedback loop section

    FBK OUT and FBK IN jacks

    Output phase switch

    FBK VCA in/out switch

  • CROSSFADER - Voltage controlled crossfade between input and feedback

    Input pre/post drive crossfade switch

    DYNAMICS envelope normalized to mix CV input

Things to Do with Dark Matter:
  • Excite audio signals to the breaking point with 4 flavours of voltage controlled overdrive

  • Turbo charge percussive hits and drum beats

  • Add sub-octave tones and timbrel richness to melodies and bass lines

  • Tweak your tone with a crunchy overdriving 2 band EQ

  • Add signal ducking and gating effects with the built in envelope follower

  • Go the feedback way and create meandering loops through your rack using the 10 I/O jacks... Feedback your feedback your feedback
