FXpansion Etch Red: an exciting and great-sounding filtering effect based on DCAM circuit-modelled technology, and now available as a Reason Rack Extension. Etch Red's dual filters feature realistic audio-rate FM, flexible routing and 4 filter models offering a total of 38 filter responses and allowing all manner of fat and warm subtractive tone-shaping.
Alongside 3 classic synthesizer filter circuits, Etch Red also includes a stunning comb filter model for creating mind-bending psychedelic effects.
Additional distortion and compressor stages are provided for beefing up signals, and FXpansion's TransMod modulation system lets you contort Etch Red's circuits over time. Use inter-modulating LFOs, envelopes and more to drive the filter cutoffs, FM amount, distortion and compression amounts, panning, wet/dry mix and much more.
Etch Red contains a number of CV and audio patch-points for integrating its circuits into your Reason projects: feed in CV from elsewhere to modulate parameters or retrigger the on-board LFOs, envelope or the sample and hold. You can even send in any audio signal as an audio-rate filter FM source. The internal modulation devices are also exposed as outputs, so they can drive other Reason devices' parameters.
Etch Red can do amazing things to all kinds of audio material and is great for subtle warming, deep tone sculpting, wild sweeps, special effects and experimental sonics.
