Tutorial: 1 Knob Filtering Systems with RC-20 Retro Color

In this tutorial I am going to show you how easy and awesome it is to gt vintage sounds and tones with the RC-20 Retro Color Saturation Plugin By XLN Audio.

Get the RC-20 – PIB/RC20-XLNAudio

This plug is great for getting that vintage feel for your tracks that are produced in the the 21st century. There are 6 high quality fx modules wrapped into the VST. Each lending its own unique characteristics to the final output. Use 1 or use them all together!

My favorite aspect of this plug is the “magnitude” slider. It allows you to turn the entire VST’s output FX into a 1 knob/parameter fx rack. Like that common to us Ableton Live users.

In this tutorial I talk a bit about the plug and show you how to set up a custom magnitude filtering effect for a track.

Release Notes

Your Sound. In Color.

RC-20 Retro Color is a creative effect plugin that adds life and texture to any recording. It easily recreates the warm, cozy feeling of vintage recording equipment, but also works perfectly in any modern production setting.

  • Adds life and texture inspired by classic gear
  • Great on drums, guitars, keys, bass and full mixes
  • Flux Engine adds warm, analog-style fluctuations

6 Unique FX Modules

RC-20’s six unique FX modules can replicate everything from vinyl records to VHS machines, adding noise, wobble and dropouts to your tracks. Its raw distortion and crunchy bit reduction will add grit to your bass and drums. The space and chorus effects will make your guitar sing like never before and the filtering effects fit right into the most modern club track.

Flux Engine

Our exclusive Flux Engine adds subtle (or not so subtle) instability and fluctuations to all of the FX modules, providing the character, warmth and analog goodness of yesteryear’s best technology.

Magnitude Slider

The Magnitude slider controls the intensity of all processing. Easily accessible all the time — even when browsing presets — it makes it easy to find the perfect sound and processing amount. Automate this control for awesome intros, breakdowns and transitions in your song.


The included presets for drums, keys, guitars, bass, full mixes and post production let you get to work right away. The RC-20 interface invites experimentation, and you can access the processing amount of each FX module while browsing.
