INTRODUCTION
Thanks for using RC-20 Retro Color!

What makes sound interesting? What makes it grab our attention?
When we started this project, we spent a lot of time talking about order versus chaos, why some oldnoisy equipment sounds so pleasing to the ears and why vintage analog synths are just so much fun.
What is the secret ingredient?
We had a hunch that in this modern digital precise world there is safety and warmth to be found in
non-linearity and unpredictability. What may once have been seen as undesired imperfection now
feels organic and soothing. The wall-of-noise of yesteryear's cassettes, that wobbly VHS sound. The
distortion, the fizzle, the less than perfect frequency response. Even the unpredictability ofequipment due to temperature, humidity, vibrations, or where the planets are in the sky.
Magic seems to happen when something comes alive all on its own, without you planning it out
beforehand.
Ok, back to planet Earth - how do you put all this into a product? Well, we played around in the labwith all kinds of source material and algorithms to figure out what worked. And - out of the smoke RC-20 Retro Color was born. Finally our love of recording artifacts like noise, distortion, tape wow &flutter, the grittiness of early sampling and more fun stuff has taken (almost) physical form!
RC-20 has six main FX Modules, each providing one piece of the puzzle. For each module, our custom
Flux Engine replicates the randomness of the known universe, and adds life, texture and analog
goodness to the sound.
The included presets cover a wide variety of use cases, from individual instruments to full mixes andpost production. As always, we hope the functionality to a large extent is self explanatory and invites
experimentation.

This manual is pretty short, so why not lend it a couple of minutes to make sure you get the mostout of this thing!

INTERFACE OVERVIEWTOP SECTION

Click the RC-20 logo to open the Credits & Help Page.
Click the Preset Name or the LOAD button to open the Preset Browser. From here you can load anyof the included ("XLN Audio") presets as well as the ones you've created and saved yourself ("UserPresets"). You can also rename or delete your User presets.
Save your own 'User' presets by clicking the SAVE button.
The Magnitude slider works as a "global" amount control for the entire plugin. It basically controls
all six big knobs at once, as well as the controls in the bottom Master Section (In, Out and EQ). Thismeans you can go from a dry unprocessed sound to full blast wobbly distorted mayhem using only
this one (automatable) slider.
2FX MODULE SECTION

Incoming audio (generally) passes through the six modules from left to right.

NOISE
There are a number of different noises Types available, ranging from vinyl record crackle to cassetteand VHS noise and much more.
Tone is a basic "tilt" style tone control: turning it clockwise means more high end and less low end
and vice versa.
With Follow you can make the noise level follow the input signal level. Great on drums! At 0 % thenoise level is static. (When you hit stop in your DAW the noise fades out though.)
As Noise is the first FX module, it normally appears in the beginning of the signal chain so it will be
distorted, crushed, filtered and fluttered along with your source audio. Activating Routing |Post lets
you re-route the noise so it is inserted at the end of the effect chain, after the Master Section EQ.
The Duck knob lets you create a ducking effect, i.e. the noise level is pushed down by incoming audio
peaks, mimicking the effect of a "pumping" compressor with slow attack.
Note: The Noise module adds noise to the incoming signal, but does not change the incoming audio
in any other way.
The Big Knob controls Noise Volume.

3WOBBLE
This module modulates the pitch (and speed) of the incoming audio, much like classic taperecorders. The two classic artifacts Wow (slow) and Flutter (fast) are there of course, and the
Wow/Flutter Balance slider lets you adjust how much you want of each.
For good measure we added a Stereo mode for the Wow section, which basically turns this into a
nice chorus - the Mix knob comes in handy here, turn it down to 50 % or so for a nice lush sound!
The Big Knob controls Wow & Flutter Amount (i.e. depth).

DISTORT
Dirty up the sound with some distortion! Several Types are available, and a Focus Filter lets you
select the frequency range where the distortion will be applied. This lets you distort only themid/high range while leaving the bottom intact for example.
Use the Mix knob to set the balance between Distorted and unprocessed sound.
The Big Knob controls Distortion Amount.

DIGITAL
Celebrate and simulate the sampling technologies of yesteryear, when the word "Digital" was socool you'd put it in your song lyrics. The Rate/Bits Balance slider lets you set the desired balance ofsample rate and bit depth reduction.
Smooth lets you polish off the rough digital edges for a less harsh sound.
The Focus Filter lets you select the frequency range where the "crushing" will be applied. Works
great to get some crunch in the top of a kick while leaving the bottom untouched. There is also a
CUT option which simply removes the frequencies outside the selected focus range.
Use the Mix knob to set the volume balance between the crushed and unprocessed sound.
The Big Knob controls Rate & Bits Reduction Amount.

SPACE
This is a reverb/resonator effect. Decay controls the length of the reverb tail. PreDelay lets you place
the reverb slightly after the source sound to reduce muddiness.
The Focus Filter controls the resonance/damping of the reverb itself and can sometimes have drastic
effect depending on source material.
The Stereo switch can turn mono material into stereo, but also provide a wider space for all types ofmaterial.
The Big Knob controls Dry/Wet Balance.

MAGNETIC
This module simulates all kinds of funny stuff that happens with volume when recording on
magnetic tape.
Wear means you played your tape too many times, the magnetic particles are starting to wear thin
making the volume fluctuate a little (or a lot).
Flutter is a faster artifact usually caused by the capstan pin in the tape mechanism.
The Wear/Flutter Balance slider lets you find the perfect balance between them.
Dropouts are similar to wear, but more intense - basically random sudden drops in volume.
The Stereo switch lets you choose if wear and dropouts does the same thing in both speakers or not.
The Big Knob controls Wear/Flutter/Dropouts Amount.

FLUX

Our FLUX engine simulates all kind of organic and non-linear fluctuations under the hood, allcustomized specifically for each module. Adding just a little bit of Flux can really add life and texture
to your tracks. Adding a lot can make things cosmically wild and crazy!

BIG KNOB SECTION

Enable buttons
Turns a module on and off. Off means the effect is entirely bypassed. When a module is turned off it
is covered by a "hatch". You can click on the hatch to turn it on.
Big Knobs
Adjusts the amount of each effect. At 0 % the module is completely bypassed. If a module is turnedoff (hatched) you can click/move the big knob to turn it on.
5MASTER SECTION

INPUT SECTION
Use the Gain knob to adjust the input level. The level is usually not super critical, but feel free tocrank it up to drive the DISTORT and DIGITAL modules harder for example.

EQ SECTION
Use the Enable button to turn the entire EQ section on and off.

CUT FILTER
This filter lets you cut out unwanted frequencies at the bottom and/or top end of the spectrum. The
steepness of the filter can be set to Soft or Hard on both ends.

TONE
This control offers a simple way to shape the tone of the final sound.
In TILT mode, turning the knob clockwise turns up the high end and turns down the low end. Turningthe input knob the other way has the opposite effect.
In MID mode the knob controls the mid frequencies, giving your sound a nice smiley/frowney curve.

OUTPUT SECTION
Use the Gain knob to adjust output level to taste. This is great when you want to match the levels ofprocessed/unprocessed sound for A/B comparison, or if you want to be able to automate theMagnitude and control the levels of the processed sound.
The Width knob lets you adjust the stereo width from 0 % (mono) to 100 % (original stereo image) to200 % (exaggerated stereo effect). The results may vary depending on source material and effects
applied.

6PRESET BROWSERClicking on the Preset Name or the LOAD button in the Top Section opens the Preset Browser.
On the left, choose to list All Presets, XLN Presets (made by XLN) or User (made by you). The preset
