Description

Unleash the raw, untamed energy of your modular synth setup with the BASTL Instruments Dark Matter Voltage Controlled Audio Feedback Module. This feedback sound processor invites you to explore the chaotic yet musical realms of controlled feedback, transforming your soundscape into an electrifying sonic adventure. With its powerful input amplifier, equipped with a VCA and adjustable overdrive, you have the tools to push your audio signal to the edge and beyond.

Featuring an internal envelope follower, the Dark Matter is designed to seamlessly integrate with your rig, normalizing to the crossfader and feedback CV input. Two-band equalization offers level and boost control with CV inputs per band, giving you precise tonal shaping abilities. The feedback section, complete with level control, CV input with an attenuator, polarity switch, and external signal input, provides a playground for creating dynamic and evolving sound textures.

The crossfader, with CV input, allows for smooth transitions and creative modulation possibilities. Separate outputs for the crossfader, envelope follower, and feedback provide flexibility and expansive routing options, making the Dark Matter a vital component for any experimental sound architect.

Key Features:

  • Feedback sound processor
  • Input amplifier with VCA and adjustable overdrive
  • Internal envelope follower, normalized to crossfader and feedback CV input
  • 2-band equalizer with level control, boost control, and CV input per band
  • Feedback section with level control, CV input with attenuator, polarity switch, and external signal input

Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about BASTL Instruments Dark Matter Voltage Controlled Audio Feedback Module.

Features and functionality

  • The Dark Matter module uses a positive feedback system to create unique audio textures, with extensive patch points and hidden switches for fine-tuning.

    Source
  • It's noted for having all jacks at the top, making it ideal for bottom row placement, reducing cable clutter.

    Source
  • The module can be used as a parallel distortion for percussion, achieving a unique 808 distortion sound when combined with a gate and envelope tweaks.

    Source
  • The envelope follower component can be patched out to other modules, expanding its utility beyond feedback experimentation alone.

    Source

User experience

  • The module's 13hp size can be challenging for case planning but is useful for fitting additional small expanders.

    Source
  • Owners appreciate the module's ability to control feedback subtly, allowing for nuanced sound exploration from gentle to aggressive.

    Source
  • Owners find that splitting the audio signal before the module and mixing the original with the effected signal can prevent overwhelming distortion.

    Source

Use cases and applications

  • Users enjoy pairing the feedback loop with nonlinear modules like xaoc 8-bit converters for experimental sound design.

    Source
  • Alternating attenuated envelopes for treble and bass can create dynamic patches, offering a heavy sound without muddying the mix.

    Source
  • Owners highlight its ability to transform kick drums into bass lines, drops, and drones, especially effective when sliders are manipulated for rhythmic chaos.

    Source
  • Incorporating other modules in Dark Matter's effects loop can yield experimental textures, with sweet spots that are highly musical within the right context.

    Source

Comparisons

  • Some users compare its versatility and complexity favorably with other Casper Bastl modules, though each has its unique applications.

    Source
  • Some users prefer Ritual Electronics Miasma for techno, noting it has a warmer tone and is easier to control while still offering feedback and distortion.

    Source

Mods and upgrades

  • Users suggest using a filterbank, EQ, or notch filter in the feedback loop to adjust specific frequencies for finer control over sound output.

    Source
  • A VCA within the feedback loop is recommended to tame the wild nature of the Dark Matter, offering more nuanced audio manipulation.

    Source

Setup and maintenance

  • Applying multiple attenuators to CV inputs can help widen sweet spots by providing super fine control over parameters.
