SSL X-Gate is a comprehensive mixing tool inspired by classic analogue gate hardware and workflow from SSL's Live and Broadcast consoles, as well as introducing new creative capabilities and an intuitive left-to-right co-ordinated visualisation.
- Easy-to-use THRESHOLD and RANGE controls, visually aligned with WAVEFORM GRAPH and GAIN REDUCTION METER for coordinated control
- ROLLING WAVEFORM VISUALISATION GRAPH for setting the perfect threshold
- Hysteresis - split OPEN and CLOSE THRESHOLD behaviour
- ATTACK, RELEASE and HOLD time parameters gives detailed control over the shaping of the audio
- Tune the performance of the gate using the interactive FILTER GRAPH to apply HIGH- and LOW-PASS FILTERS the sidechain signal
- Use the EXPANDER mode and accompanying KNEE control for a more transparent option: make quiet signals quieter, and expand the dynamic range of the signal
- Simple discrete LOOKAHEAD options for minimising the latency when using a lookahead
- Transform the plug-in into a production ducker with a single click – use DUCK mode to invert the sidechain logic, attenuating the signal only when it exceeds the threshold i.e., to duck the music when you speak into your microphone
- Tailor the gate to best suit your source material using PEAK/RMS DETECTION options
- Tri-colour TRAFFIC LIGHT CUES give a clear indication on the momentary open/closed/hold state of the gate
- Use the MID/SIDE processing options to trigger the gate in creative ways or gate only the mono or stereo components on the signal
- SIDECHAIN and GATE audition modes for setting the perfect values

Installation and Download
You can download installers for a plug-in from the website's Download page, or by visiting a plug-in product page via the Web Store.
All SSL plug-ins are supplied in VST, 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 VST, 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.
Visit iLok, Licensing and Activation for guidance in activating your SSL plug-in.
All numerical controls can be dragged to change the value, including all of the circular controls, numerical inputs and the flags/tabs.
Hover over a control and use the mouse wheel to increase/decrease its value.
Double-click any of the numerical controls to directly type in a value.
The OPEN and CLOSE THRESHOLD parameters can be set by dragging the flags on the graph. Click and drag between the thresholds to move both thresholds at once.
Click and drag in the area above the upper threshold to move only the upper threshold. Click and drag in the area below the lower threshold to move only the lower threshold.
You can also change the filter cutoffs by dragging the handles directly on the filter graph.
FINE control (hold ⌘/ALT)
Hold ⌘/ALT while dragging a control to enter 'FINE' control mode. This causes all interactions with numerical input to have finer control - including the increment/decrement buttons!
The BYPASS button at the top right of the plug-in window allows the user to bypass all plug-in processing. In some supported DAWs, this bypass is linked to the DAW bypass.
The INPUT Meter shows the instantaneous value of the INPUT signal.
If the signal is very loud or is clipping, this is indicated by a red segment at the top of the metering.
The INPUT GAIN control to the bottom left of the plug-in window allows the adjustment of incoming signal to X-Gate to allow the desired control of the signal against the GATE THRESHOLD & allows adjustment to +/- 24 dB.
The OUTPUT METER shows the instantaneous value of the OUTPUT signal.
If the signal is very loud or is clipping, this is indicated by a red segment at the top of the metering.
The OUTPUT GAIN control to the bottom left of the plug-in window allows the adjustment and trimming the output signal from the plug-in up to +/- 24 dB.
The MIX Knob sets the blend between the 'Wet' effected signal post GATE Processing and the Original 'Dry' Input Signal. This is an easy way to 'dial back' the overall effect of the plug-in. One effective technique is to apply some severe gating, then reduce the MIX a bit to make it feel more natural.
Open and Close Thresholds
At the core of the gate processor are two thresholds: OPEN and CLOSE. The uppermost threshold is displayed on the left, and the lower threshold is displayed on the right.
The OPEN (UPPER) THRESHOLD sets the signal level above which the GATE OPENS, when the gate is closed.
* When in DUCK MODE, the UPPER THRESHOLD becomes the CLOSE threshold this sets the level above which the gate closes.
The CLOSE (LOWER) THRESHOLD sets the signal beneath which the GATE CLOSES, when the gate is open.
* When in DUCK MODE, the LOWER THRESHOLD becomes the OPEN threshold, and sets the level below which the gate opens.
What is hysteresis?
The difference between the OPEN & CLOSE THRESHOLDS is referred to as hysteresis. SSL console gates typically include a built-in hysteresis, which is carefully designed to prevent the gate from quickly flipping on and off.
In X-Gate, you can visualise and set the hysteresis by setting the OPEN & CLOSE THRESHOLDS to different values.
Max Gain Reduction
The MAX GR (GAIN REDUCTION) level represents the maximum dB value between the OPEN & CLOSED Gated & undated signals.
The All-in-One Visualiser
The WAVEFORM GRAPH (above, left) allows X-GATE to visually represent key parameters in an all-in-one display. In combination with the I/O Graph (right) it is deeply revealing in how the gate processes the incoming signal.
To the right of the INPUT METER, the incoming signal is represented as dB / time, allowing the user to see peaks in the waveform and identify the ideal position for for the OPEN & CLOSE THRESHOLDS against the incoming signal.
Setting the Open and Close Threshold
In addition to setting the OPEN THRESHOLD & CLOSED THRESHOLD parameters using the numerical inputs, you can interact with them directly on the graph. The flags marked in green & red can be dragged up and down to set their values against the waveform.
The decibel scale is matched across all meters and graphs for an intuitive, left-to-right visualisation of what the gate is doing.
A traditional representation of a dynamic processor response is presented to the right of the WAVEFORM GRAPH. The I/O GRAPH shows the input signal against the expected output signal. This is especially useful for visualising EXP and DUCK modes.
An average of the instantaneous value of the signal is indicated by a cross on the I/O GRAPH.
The LOOKAHEAD control introduces a delay to the signal, allowing the processor more time to react to the incoming signal. In practice, this means that gate can respond more quickly and accurately to changes in the incoming signal, but with the caveat of introducing latency.
Rather than a continuous lookahead, we present several static options. This allows X-Gate to introduce the minimal amount of latency for each lookahead options, rather than having to introduce the maximum delay (15ms) for smaller lookahead values.
The LOOKAHEAD can be changes from OFF all the way to MAX (15ms).
The introduced delay is automatically reported by the plug-in to your DAW, to allow for automatic delay compensation.
Traffic Lights System
Inspired by classic hardware gates, and visualisation established throughout SSL's Live and Broadcast console range, X-Gate utilises an intuitive Traffic Light System for quick visual feedback about the gate's current status.
- Closed = Red
- Hold = Amber
- Open = Green/Amber
X-Gate features a flexible SIDECHAIN circuit that lets you sculpt incoming signals to tailor the gate trigger for specific & creative purposes.
S/C Filters and Visualisation Graph
The S/C Visualisation Graph (above), displays the frequency range on the SIDECHAIN signal. In order to focus the SIDECHAIN to a limited frequency band, X-Gate allows the option to engage the LF & HF bands of the SF FILTER, then set the frequency of each band by either dialing in the settings on the LF & HF CUT knobs (as shown below), or by dragging the flags to the desired position within the Visualisation Graph itself.
For Stereo Sources, we can also alter the SIDECHAIN signal using the SC M/S Knob, altering the incoming detection from focusing on MID only content, through to only SIDE content from the stereo source. In it's centre position (as shown) the SIDECHAIN signal remains untouched.
External Sidechain and Sidechain Listen
X-Gate includes the option to SIDECHAIN the gate form an external sound input. To activate this, simply set up your DAW's internal plug-in routing system to select the source signal, then activate the EXT Button to engage this signal as the Gate Trigger.
The SIDECHAIN LISTEN Button focuses the Plug-In's audio output to the SIDECHAIN signal; either externally, or the source material with the LF & HF CUT applied if activated.
Ballistics and Shaping
The ATTACK Knob adjusted the rate the gate initiates opening to allow signal though once passed the Threshold after being triggered.
The HOLD Knob adjusts the time in milliseconds that the GATE is held open following the signal passing back below the OPEN THRESHOLD with the rate being between 2ms to 2000ms (2 seconds)
The RELEASE Knob adjusts the decay time in milliseconds of the GATE closing when the signal has passed below CLOSE THRESHOLD. The rate being between 2ms to 4000ms (4 Seconds)
The KNEE Parameter is only available in EXP (Expander) mode, & adjusts the ratio of GATE KNEE to allow for a more natural volume roll off beneath the CLOSE THRESHOLD by smoothing the transition between open & closed states.
X-GATE's Gate detection can be switched between RMS or PEAK to best suit the Gate input or EXT signal. The Detection button is located under the Traffic Light Display & features a drop down menu allowing the selection of the appropriate setting.
Gate, Expander and Duck Modes
X-GATE features three different operational modes, each allowing for alternative controls to tailor the Gate for different purposes.
In X-Gate's default state, alternatively known as GATE MODE, the two buttons below MODE will be black to show their disengaged state (as below).
GATE MODE's visualisation plane on the Left of the Plug-In shows the OPEN THRESHOLD in line with the WAVEFORM GRAPH and the steep fixed CUT OFF when the signal decreases below the CLOSED THRESHOLD, with the MAX REDUCTION Meter to the Left to determine how far the dB value falls below the OPEN THRESHOLD
To activate EXP MODE, first you must click on the EXP Button which will turn green when engaged.
In EXP MODE the FIXED CUT OFF is less drastic to allow a more natural gated sound. Again the OPEN & CLOSED THRESHOLD Level is aligned with the WAVEFORM GRAPH, but now the user can modify the KNEE to further control the output signal to retain a more natural character.
To activate DUCK MODE, first you must click on the DUCK Button which will turn green when engaged.
In DUCK MODE the Gate's SIDECHAIN operation logic is inverted, attenuating the incoming signal when the SIDECHAIN INPUT Signal Exceeds the threshold.
Again the OPEN & CLOSED THRESHOLD Level is aligned with the WAVEFORM GRAPH, but now the CLOSED & OPEN Thresholds are also inverted.
The GATE M/S Knob alters the balance between processing the MID Signal or SIDE Signal of the INPUT.
The GATE LISTEN when engaged, switches the audio output of the plug-in to audition the signal NOT passing though the gate. eg. the REMOVED portion of the original signal. This is useful to gauge if any part of the signal is being cut too extraneously.
X-Gate ships with several plug-ins to aid your workflow, including several carefully designed presets for different common gating applications such as presets to resolve Snare Mic & Vocal Bleed as well as more creative uses such as the 'Gentle Mastering Expander' to revive dynamics in a heavily compressed Mix.
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 X TO Y is used to copy presets between A/B.
SSL plug-ins come with a built-in UNDO/REDO stack, in case your DAW doesn't handle this. UNDO undoes the current action in the history stack. REDO re-does the next action in the history stack.
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.
