Thenatan has released GRRR, a beat-reactive growl designer plugin for macOS and Windows. Rather than applying a static distortion curve, GRRR listens to the incoming signal and drives four processing engines in sync with its transients, snarling on the hits and slurring back down between them.

Thenatan has released GRRR, a beat-reactive growl designer plugin for macOS and Windows.

Rather than applying a static distortion curve, GRRR listens to the incoming signal and drives four processing engines in sync with its transients, snarling on the hits and slurring back down between them.

A flat 808, a lifeless vocal or a plain loop can be pushed into a full growl using a beat-detector rather than a fixed envelope shape, with each engine controlled by a single knob.

The useful part

Thenatan has released GRRR, a beat-reactive growl designer plugin for macOS and Windows. Rather than applying a static distortion curve, GRRR listens to the incoming signal and drives four processing engines in sync with its transients, snarling on the hits and slurring back down between them. A flat 808, a lifeless vocal or a plain loop can be pushed into a full growl using a beat-detector rather than a fixed envelope shape, with each engine controlled by a single knob.

How it works

  • Master section with SUB (octave-down weight) and DENSE (global drive/sweep/resonance/gating scaling).
  • 20+ factory presets covering bass growls, vocal monsters, drum destruction and riddim lasers.
  • Price and Availability GRRR is available now for macOS and Windows in VST2, VST3 and AU plugin formats for $49...

Details worth keeping

Four beat-reactive engines: TRASH (wavefolding, decimation, ring-mod). TALK accelerates up to 4x on transients before slurring back down. Per-rack Mix and Bypass on all four engines for instant A/B.
