Welcome

Thanks for joining fedDSP.

Our mission is simple: to capture the unpredictable, non-linear magic of analog hardware and bring it into the digital domain without compromise. We don't just model circuits; we model the behavior, the quirks, and the sound that makes hardware unique.

We hope these tools inspire you to create something new.

License Key Activation

All fedDSP plug-ins require a valid license key to operate.

Purchase: After purchasing a plug-in from fedDSP.com, you will receive a license key via email. You can also find this key at any time in your Account page, by creating an account using the same email used to make your purchase.
Install: Download and install the plug-in for your operating system (macOS or Windows) from our Downloads page.
Activate:
- Open your DAW and load the plugin.
- On the first launch, you will see an activation screen.
- Copy your full key including BEGIN and END lines and paste into the activation screen. It should look like this:
```
  -----BEGIN fedDSP LICENSE-----
  (full license key)
  -----END fedDSP LICENSE-----
```
If either BEGIN or END line is missing, the license will not work.
- Click Activate.
- You're ready to make music.

If you have any problems with installation, please see our installation FAQ.

Our End User License Agreement permits you to activate your license on up to 3 separate machines.

fedDSP User Interface

All fedDSP plugins share a common set of interface controls designed to speed up your workflow.

Top Bar

The top bar of every fedDSP plugin provides access to global settings and preset management.

fedDSP logo: The fedDSP logo on the top left allows easy access to license management, as well as a direct link to this manual.
< >: preset left / right (quick navigation).
Preset Selector: Click to open full preset list. You can save, load, and organize your own user presets here. User presets are stored in the user AppData/presets location.
A/B Compare: Switch between two different states of the plugin to compare settings instantly.
Copy A > B: Copies the settings from state A to state B.
Undo / Redo: Stepped undo functionality to track back through your tweaks.
+: Access to the Advanced Panel, allowing deeper control of the plugin when you need it.
BYP: Bypass button, instant, no click.

Keyboard Shortcuts

FedDSP finally brings keyboard shortcuts to the world of audio plugins! Speed up your mixing with these standard keyboard modifiers.

(Please note that shortcuts work only when the plugin window itself is focused, so click anywhere on the plugin UI first before using the shortcut key.)

m, toggles between the MODE of the plugin (on FIERY this toggles classic and vintage, on PHATurator it toggles PHAT, PHATTER or CLEAN, etc).
a, toggles between State A and State B (A/B).
c, copies the current state into the other state instantly (fast A→B or B→A copy).
b, bypasses the plugin (same as top-bar BYP).
i, opens the Advanced Panel (same as top-bar +).
p, opens the preset list.
Shift + → or Shift + ←, change preset: right = next preset, left = previous preset.

Other UI Tips and Tricks

Reset to Default: Double-click any knob or slider to reset it to its default value.
Fine Tune: Hold Shift while dragging a knob to adjust the value in smaller increments.
Manual Entry: Right-click (or control-click) a control to type in a specific value.

PHATurator

PHATurator is a multi-stage saturation and tonal-shaping plugin designed to add weight, presence and musical character while staying light on CPU.

Multiple analogue-inspired stages (TUBE, TAPE, FET, PUNCH, PHAT, WARMTH) allow you to blend to taste, from subtle warmth to absolute madness.

MAIN INTERFACE

Multiple analogue-inspired stages (TUBE, TAPE, FET, PUNCH, PHAT, WARMTH) you can blend to taste, from subtle warmth to absolute madness.

FET, detector-driven FET dynamics (76 style feel) for punch and control.
TUBE, classic tube saturation to make everything fuller.
TAPE, great for vintage glue, tasty saturation and width.
PUNCH, fast and punchy large format British console saturation: tight low end, snappy transient and an assertive upper mid band.
PHAT, fuller low-mid punch and pleasing compression-like behaviour. This is a very loudness-friendly kind of saturation.
WARMTH, thick, transformer rich 70s British class A preamp vibe: bigger lows, creamy low mids and a sweet forward presence.
MIX (global), lets you do in-plugin parallel processing.
HPF, Butterworth HPF when in clean mode, PHAT and PHATTER add resonance to it. This HPF is pre-saturation, so it helps to shape the saturation character.
LPF, Butterworth LPF pre-saturation, so it helps to shape the saturation character.
DEPTH, subtle or not-so-subtle low end enlarger. It’s a combination of EQ and very kind saturation that enlarges (or thins out) the low end. Very powerful.
TONE, when CLARITY is ON this is a carefully fine tuned high shelf to brighten up any source without harshness, when CLARITY is OFF this becomes a tilt EQ to make the source brighter or darker.

ADVANCED PANEL

MODE, toggles three behaviours: CLEAN it does what it says on the can, PHAT subtle transformer like saturation + small resonance on the HPF frequency and PHATTER dual transformer saturation + accentuated resonance on the HPF frequency.
LIMITER MODE (OFF / SAFE / AGGRO), is a lightweight but mega powerful post-output limiter to avoid final clipping (-0.003 dB final clip). Use SAFE for transparent control, AGGRO for fast peak control.
CLARITY/TILT, changes the TONE character: when in CLARITY mode the TONE is more shelf-y, when it’s in TILT mode the tone behaves more like a fine tuned tilt, that helps make the source brighter or darker.
AUTO GAIN, RMS based auto trim that keeps perceived loudness steady after heavy processing, making A/B comparisons fast and reliable.
MIX (global), lets you do parallel processing in-plugin.
OUTPUT HPF/LPF (global), is a second set placed on the output of the plugin, right before the limiter in the wet path.

ELEGANTE

ELEGANTE is a zero-latency, CPU-light saturation and utility plugin that can be used for mixing, tracking and creative duties.

Loosely inspired by the classic TS-style overdrive, this plugin is built around an original circuit that captures the legendary mid warmth and amp-pushing feel. From there, it goes further with expanded controls for deeper tone shaping, flexible EQ, pre and post filtering, polarity flip, and precise high pass and low pass filters. The result is a guitar overdrive with true TS soul that also shines as a creative mixing tool for tracking and sound design. Classic character with modern versatility.

MAIN INTERFACE

DIST controls the amount of saturation injected in the signal.
TONE controls a clever tilt/LPF with variable Q to shape the EQ of the source before saturation.
LEVEL boosts or reduces the volume post saturation stage.
BARK adds some "bark-y" mid range, to make every source feel more in your face.
INPUT controls the signal coming into the effect and OUTPUT controls the signal coming out of the effect.
POWER TOGGLE toggles the effect on and off.

ADVANCED PANEL

MONO / DUAL MONO / STEREO changes behaviour based on the track format. Mono instance: the MONO button is shown but it's disabled, because there is no option available. Stereo instance (2 channels), you may select between: DUAL MONO, where left and right channels are processed independently - or STEREO, where both channels are linked and the limiter will apply the same gain reduction, helping keep the stereo image stable.
LIMITER MODE (OFF / SAFE / AGGRO) is a post-clamp lightweight but mega powerful post-output limiter to avoid final clipping (-0.003 dB final clip). Use SAFE for transparent control, AGGRO for fast peak control.
PH toggles the polarity. The button shows "PH 0" for normal polarity or "PH 180" for reverse polarity (180°).
FILTERS toggles the position of HPF and LPF in the signal chain. The button shows "FILTERS: PRE" to indicate that the HPF andLPF are processed before the pedal, or "FILTERS: POST" to indicate that the HPF and LPF are processed after the pedal.
MIX controls the mix between the dry signal and the processed signal.
HPF adjusts the cutoff frequency of the HPF. The range is 20Hz to 2,000Hz.
LPF adjusts the cutoff frequency of the LPF. The range is 2,000Hz to 20,000Hz.
