Introduction
SSL autoDYN combines the sonible AI engine with SSL's legendary channel dynamics processing. The sonible AI engine will give a recommended set of parameters for the compressor and gate, both modelled on SSL’s 4K E channel strip, taking into account your chosen Style and Profile. The graph in the centre will show you the gain reduction history, allowing you to use the individual parameters to perfect your signal’s dynamic signature.
Key Features
- Provides the signature and sought-after sound of the SSL 4K E Channel Strip plug-in
- AI Assistance leveraged from sonible’s industry leading machine-learning research and development, proven in many other AI-assisted plug-ins from the sonible team
- No compromise in functionality—you always have direct access to all of the original dynamics controls, just like the real thing; you can take over steering the ship at any point
Release Notes
Version 1.0.5 (January 2026)
- First release.
Supported Platforms & Hosts
For compatibility information about plug-ins, visit the Plug-in Operating System and DAW Compatibility FAQ.
When we release an SSL plug-in, we test it on all currently supported Windows and macOS operating systems that aren't End-of-Life (EOL) at the time of release. We test the plug-ins on a range of DAWs, using the latest version publicly available version of each one. It is possible our products may work on platforms outside of this list. However, if you are using a DAW not listed in the linked article, or an older DAW version (perhaps several years old), we recommend you demo the product before purchase to confirm that it works correctly. For 360°-enabled channel strip plug-ins, refer to the UC1 User Guide for tested DAWs and their integration capabilities.
Apple Silicon Support
This plug-in is provided as a universal binary for macOS and features native support for Apple Silicon.

- Select a location to activate the license to, and click 'Next'.
Installation & Download
If you own perpetual licenses for your products, we recommend using the SSL Download Manager application to to easily manage all SSL plug-in installations all from one place, on both macOS and Windows. In addition to easily installing, uninstalling or reinstalling individual or every SSL plug-in at the click of a button, the SSL Download Manager also provides you with detailed release notes and lets you know when updates are available.
You can also download offline installers for a plug-in from here.
If you are a subscriber to Complete Access, we recommend using Complete Access Hub to download, install, and activate all of the plug-ins (SSL, Harrison, and Slate Digital) that are included in the subscription.
All SSL plug-ins are supplied in VST3, AU (macOS only) and AAX (Pro Tools) formats.
The installers provided (macOS Intel .dmg and Windows .exe) copy the plug-in binaries to the common VST3, AU and AAX directories. After this, the host DAW should recognise the plug-in automatically in most cases. Simply run the installer and you should be good to go. You can find more information about how to authorise your plug-ins below.
Licensing
Visit iLok, Licensing and Activation for guidance in activating your SSL plug-in.
EQ Controls & Functions
SSL autoDYN features a fully functional and identical version of the SSL 4K E gate and compressor. You can just tweak these settings like on the normal 4K E channel strip, or you can make use of the sonible AI engine to make a suggested setting based upon incoming audio (see next section about sonible AI Controls & Functions).
1. INPUT
The gain applied to the input signal. Not included in the sonible AI engine recommendations.
2. EXT S/C
Enables the external sidechain input to the gate and compressor. Not included in the sonible AI engine recommendations.
3. FAST
Provides a faster attack time (3ms per 20dB gain reduction). When off, the attack time is slower and less aggressive (30ms per 20dB of gain reduction).
4. RATIO
Controls the strength of the gain reduction applied to the input signal when the sidechain* signal’s level exceeds the Threshold. When set to 1, the compressor is bypassed.
*The sidechain signal is the same as the input signal while EXT S/C is disabled.
5. MIX
Determines the mix between the compressed signal and the dry/pre-compressed signal. 100% means the signal is entirely passed through the compressor, and 0% is an entirely dry signal. Using a blend between 0 and 100% is commonly referred to as "parallel compression".
6. THRESH
Sets the compressor threshold from +10 to -20 dB. The threshold determines the level above which compression occurs. Like the 4K E channel strip, Threshold also applies an automatic gain make-up.
7. RELEASE
Controls how quickly the signal level returns to normal after the sidechain signal level has dropped below the Threshold (measured in seconds).
8. PLOT
Shows or hides the gain reduction contribution of the Compressor or Gate sections on the gain reduction graph (17).
9. DYN IN
Toggles the dynamics processing (both compression and gate/expander) in or out.
10. Gain Reduction Metering
The left meter (orange) indicates the amount of compression (attenuation in dB) that is being applied to the signal, and the right meter (green) indicates the amount of gating (attenuation in dB) that is being applied to the signal.
11. RANGE
Controls the maximum amount of gain reduction applied by the gate/expander. When set to 0, the gate/expander is bypassed.
12. FAST
Sets the gate/expander to a fast attack time (100 µs per 40 dB). When off, a linear attack time of 1.5ms per 30 dB is applied.
13. RELEASE (Gate/Exp)
Sets how long the signal remains unattenuated after the gate/expander closes, from 0.1 to 4 seconds.
14. THRESH (Gate/Exp)
Sets the threshold level, above which the gate/expander will be opened. Variable hysteresis is incorporated in the threshold circuitry. For any given "open" setting, the Expander/Gate will have a lower "close" threshold. The hysteresis value is increased as the threshold is lowered.
15. EXP
Switches the gate into downwards expander mode with a gentle curve instead of the high ratio gate.
16. OUTPUT
The gain applied to the output signal. Not included in the sonible engine recommendations.
17. Gain Reduction Graph
This displays the input signal and combined gain reduction (from the compressor and gate) over time.
sonible AI Controls & Functions
At the top of SSL autoDYN are the controls and settings for the sonible AI engine. This is where you instruct SSL autoDYN on the type of instrument you're processing and the target style. The image below shows the top of SSL autoEQ as these controls are exactly the same on SSL autoDYN.
1. Bypass
Toggles plug-in processing in or out.
2. LEARN
Analyses ten seconds of input audio and stores this analysis, which can then be used to apply recommended processing with AUTO or SET.
3. AUTO
When AUTO is enabled, the recommended processing will be applied as soon as the source audio has been analysed.
4. SET
Manually applies the recommended processing. SET is only available when the current settings are different to the recommended settings.
5. STYLE
Selects the character of the applied processing. STYLE uses the stored analysis to tweak the parameter values, so material does not have to be re-learned for the STYLE to be changed.
6. PROFILE
Calibrates the processing to a specific sound source. Like STYLE, this can be changed after the input audio has been analysed.
7. RESET
Resets the parameters to their values of least effect.
8. Audition
Temporarily auditions the recommended settings. Can be used to preview the changes that pressing SET would make to the processing.
9. Meters
• Input meter (left): Meters the input signal.
• Output meter (right): Meters the output signal
Suggestion Indicators
When the sonible AI engine sets the various parameters, you still have the freedom to change them as you wish. When changing the buttons or knobs from their suggested positions, indicators will be shown to guide you back to the original suggestion from the sonible AI engine if you find yourself wandering too far away.
Switches which are in the position opposite of the suggestion will have a green ring around them:
Knobs which are set to values other than their recommendations will have a green ring appear around them with an indicator of the suggested direction:
SSL Plug-in Engine
The 'SSL Plug-in Engine' has several features that are available across our entire plug-in range.
NOTE: the available features in a plug-in might be or look different depending on what plug-in you are using, or when the plug-in was most recently updated.
Undo/Redo
SSL plug-ins come with a built-in undo/redo stack, in case your DAW doesn't handle this.
- Undo (left arrow) undoes the current action in the history stack.
- Redo (right arrow) re-does the next action in the history stack.
Presets
All of our plug-ins ship with carefully designed presets to aid your workflow.
Factory presets are included in the plug-in installation, installed in the following locations:
macOS: /Library/Application Support/Solid State Logic/PlugIns/Presets/[Plug-in Name]
Windows: C:\ProgramData\Solid State Logic\PlugIns\Presets\[Plug-in Name]
Switching between presets can be achieved by clicking the left/right arrows in the preset management section of the plug-in GUI, and by clicking on the preset name which will open the preset management display.
The Preset Management menu reflects the folder structure of the preset folder.
Revert Changes and Delete
- Revert Changes discards any changes to the current preset.
- Delete removes the current preset from the filesystem. Factory and Producer presets cannot be deleted from the plug-in GUI, although they can be manually deleted using the filesystem (Windows Explorer or Finder).
A/B and Copy
- A/B allows you to toggle quickly between two presets. This is useful for comparing between two parameter settings.
-
COPY A TO B is used to copy presets between A/B.
Version Number
Click the version number to display more information about the plug-in.
When logging a bug to our support team, always include the full version number e.g. v1.0.13.
Advanced Settings (not all plug-ins)
Some plug-ins have advanced functionality. Click the 'Advanced Settings' button to access advanced plug-in functionality.
This will drop the plug-in into 'Advanced Mode', exposing more settings, and allowing you to tweak the 'under-the-hood' behaviour of the plug-in.
Scale/Zoom
The scale/zoom menu allows you to resize your plug-in from 50% up to 200%.
Note that if resizing would cause the plug-in to go offscreen, then this option will be disabled. This is designed to prevent DAW resizing bugs that exist in some DAWs.
You can also right-click anywhere on the background of the plug-in to change the scale.
HQ or ECO Mode
Some plug-ins come with a HQ or ECO mode button. When in HQ mode, we introduce extra processing such as oversampling for higher quality, at the expense of more CPU. When in ECO mode, a plug-in will drop into a lower, less CPU intensive and low-latency mode (if possible).
Built-in Help
This plug-in features built-in contextual help. To turn this feature on, click the '?' in the bottom right-hand corner. Mouse over elements of the GUI to see some information about the feature.
