Reviews

Owner Insights

We analyzed real musician discussions from forums and Reddit to find what players love, question, and tweak about Noise Engineering Viol Ruina.

Features and functionality

  • Viol Ruina allows independent patching to filter or distortion, giving flexibility in sound routing.

    Source
  • Viol Ruina includes an internal modulation feature that excels at producing classic laser sounds and a 'mangle' circuit for added grit.

    Source
  • The Viol Ruina experiences a significant level drop when used as a low pass filter with any resonance, necessitating routing through the mangle circuit to compensate.

    Source
  • Owners wish for a CV input for the Mangle function, which would enhance its modulation capabilities and expand creative possibilities.

    Source

Comparisons

  • Bastl Cinnamon is similar in character and size (4hp) with consistently positive reviews, unlike the mixed feedback on Viol Ruina.

    Source
  • Terci Ruina is used more frequently for pure distortion compared to tanh, which is favored in feedback patches.

    Source
  • Kith Ruina, another module in the Ruina series, is favored for its subtle EQ-based distortion with added drive over the more aggressive Viol Ruina.

    Source

User experience

  • The filter in Viol Ruina is noted for its unique character, even when distortion isn't used, suggesting a distinct sound profile.

    Source
  • Owners note the Viol Ruina can easily become very aggressive, with some preferring other filters for their sound.

    Source
  • Users often pair the Viol Ruina with other Noise Engineering modules like the Loquelic Iteritas for complementary sound experimentation, enhancing its utility in modular setups.

    Source

Use cases and applications

  • Viol Ruina's dual-purpose design as a filter and distortion is appreciated in small modular cases with limited space.

    Source
  • Sequencing frequency CV with high Q settings on the Viol Ruina produces acid-like tones, beneficial for experimental soundscapes.

Critic Reviews

Noise Engineering Viol Ruina Combines Distortion & Filtering In 4HP

synthanatomy.com

Noise Engineering's Viol Ruina is a gritty delight for Eurorack enthusiasts, melding analog distortion with a robust 24dB lowpass filter. Its standout feature is the ability to use its filter and drive sections independently, offering versatile patching options. While its harsh resonance and feedback FM might not suit everyone's taste, it excels in adding a raw edge to experimental, noisy, or industrial music. At $133, it's an affordable choice for those seeking to inject some filth into their modular setup. Not for the faint-hearted, but a win for lovers of intense sound design.
