The Noise Engineering Viol Ruina is an all-analog distortion and lowpass filter with an internal envelope follower and self-modulating cutoff. The four-pole design is reminiscent of the classic filters we all know but with a completely new and slightly ridiculous twist. The independently addressable distortion circuit takes VR into overdriven paradise with a shocking amount of drive. Built-in envelope following makes an easy way to create dynamic patches with the flick of a switch, and feedback FM takes VR to a whole new realm of filthiness. Run a sound through VR, you’ll get something cool out of it.
- Frq: Filter cutoff frequency. Knob sums with the Frq CV input.
- Laser: Engages the internal envelope follower at different amounts, routed to the cutoff frequency. Down position is off, middle is mild, high is extreme.
- Q: Filter resonance.
- Mod: The audio is routed back to the filter cutoff frequency for input-dependent FM. Down position is off, middle is mild, high is extreme.
- Mangle: Distortion amount. Enough said.
- Frq CV: CV input for filter cutoff frequency. Responds to 0-5v.
- Filter In: Audio input to the filter section.
- Filter Out: Audio output from the filter. Normalled to the Mangle input; normal is broken when Mangle In is patched.
- Mangle In: Audio input to the distortion section.
- Mangle Out: Audio output from the distortion section.
Patch 1: Patch a simple waveform like a saw wave to the filter In jack. Patch the mangle Out jack to your mixer. Play with the Frq, Q, Mod, and Mangle parameters to hear what it can do.
Patch 2: Patch a signal with lots of dynamics and harmonic content like a drum loop into the Filter In jack. Engage the Laser section and hear how the envelope follower shapes the filter to the sound.
Patch 3: Patch a sound to drive In. Patch Drive Out to Filter In, and Filter Out to your mixer. Now you can distort your sound before the filter! Cool!
Power: 40mA @ +12v / 35mA @ -12v
