Overview

SHEEN is an analog tape saturation plugin modeled after the character of vintage tape machines — adding warmth, harmonic density, and subtle compression to your audio, from transparent glue to heavy lo-fi degradation.

System Requirements

macOSmacOS 12 Monterey or later — Intel & Apple Silicon
WindowsWindows 10 or 11, 64-bit
FormatsmacOS: VST3, Audio Unit (AU)
Windows: VST3
DAWAny VST3 or AU host (Ableton Live, Logic Pro, FL Studio, REAPER, Cubase, Maschine, etc.)

Installation

macOS

Run the SHEEN macOS installer (the .pkg file you downloaded) and follow the on-screen steps. The installer places files at:

VST3/Library/Audio/Plug-Ins/VST3/SHEEN.vst3
AU/Library/Audio/Plug-Ins/Components/SHEEN.component
Windows

Run the SHEEN Windows installer (the .exe file you downloaded) and follow the on-screen steps. The installer places files at:

VST3C:\Program Files\Common Files\VST3\SHEEN.vst3

Most DAWs find SHEEN automatically on their next plugin scan. If it doesn't appear, rescan plugins from your DAW's plugin manager.

Licensing

SHEEN runs in demo mode until a license is activated. In demo mode a brief noise burst plays approximately every 45 seconds — all controls remain fully functional.

To purchase a license visit gdpaudio.com.

To activate:

  1. Click the UNLICENSED - CLICK TO ACTIVATE pill in the plugin footer.
  2. Paste the full contents of your license file into the text box.
  3. Click Activate. The pill will change to LICENSED TO followed by the name on your license.

Your license file carries the name it was issued to, and the pill shows it (shortened if it is long). A license that carries no personal name simply shows LICENSED. Either way it unlocks the plugin in full.

Your license is stored at:

macOS~/Library/Application Support/GDP Audio/SHEEN/license.settings
Windows%APPDATA%\GDP Audio\SHEEN\license.settings

Using another computer — activate SHEEN there with the same license file. No internet connection is required.

Uninstalling

macOS — open SHEEN Uninstaller.app from your Applications folder and follow the prompts.

Windows — go to Settings → Apps → Installed apps, find SHEEN by GDP Audio, and choose Uninstall.

Both remove the plugin files and your user presets. Your license file is kept, so reinstalling SHEEN later doesn't require re-activation.

Controls

SATURATION — How much of the tape-saturated signal is blended in. 0 is the clean input; higher values bring in more saturation and the gentle tape compression that goes with it.

DRIVE — How hard the signal is pushed into the saturation stage. Higher values add more harmonic density and soft-clip compression; the high end saturates sooner than the lows, as it does on tape.

BIAS — Shifts the saturation curve. 50 is symmetrical; moving either way adds asymmetry, which changes the harmonic colour and warmth.

TONE — High-frequency tilt. Turn left for a darker tape sound, right to retain more top-end.

WOW — Subtle pitch modulation mimicking tape speed instability. Use sparingly for vintage feel.

NOISE — Adds low-level tape hiss character.

OUTPUT — Makeup gain after saturation.

IEC I / II / IV — Tape type, which sets the overall character. IEC I (ferric): more saturation and noise, slightly darker. IEC II (chrome): the neutral reference. IEC IV (metal): less saturation, brighter and quieter.

BYPASS — Hard bypass. All DSP is skipped; mono mode is preserved.

MONO — Sums stereo to mono before output. Useful for checking mono compatibility.

Factory Presets

24 factory presets are included. Click the preset name in the plugin header to open a list of every preset and pick one directly, or step through them with the < and > arrow buttons. Presets you save yourself appear at the bottom of the same list.

User presets are saved to ~/Library/Application Support/SHEEN/ (macOS) or %APPDATA%\SHEEN\ (Windows). Use SAVE to store settings, RENAME / DELETE to manage them.
