SSL SubGen is a high-quality sub-bass harmonic synthesizer that supports up to 4 independently configurable bands, generating frequencies an octave lower than the source signal - perfect for adding power and thump to snares, kicks and bass. Whether you’re looking to rebuild bass frequencies in thin-sounding or poorly recorded kick and bass guitar tracks or generate LFE content for a film mix or sound design project, SubGen provides an intuitive interface to quickly generate rumble and sub-bass.
Aside from sounding super musical – with a sub-bass generation algorithm that blends naturally with your source instrument – SubGen provides an incredibly easy-to-use interactive interface for controlling the gain, width and frequency for each band as well as workflow enhancements such as per-band solo-ing options, mix lock, and built-in contextual help.
Use the 3 tailored saturation modes (“pre”, “kick” and “bass”) alongside the gain-compensated drive control to easily dial in harmonic character for different sources. Control your sub-bass dynamics using the compressor module. The intuitive all-in-one mix allows you to blend any combination of your wet and dry signals from a single parameter, as well as dial in parallel compression and punch.
Need to tame your sub-bass? Dial in the gentle low- and high-pass filters to control the generated bass or cut unwanted high frequencies and tidy up your mix.

Bypass and I/O
Bypasses all plug-in processing.
Applies a gain to the input signal.
Applies a gain to the output signal.
Input and Output Meters
The input and output meters displays the instantaneous level (in dBFS) of the input to and output from the plug-in.
The meter has a peak-hold segment.
If your signal is clipping at the input, a red segment will light up above the meter. You can click this indicator to clear clipping.
Sets the blend between the wet and dry signals.
At -100% (fully anti-clockwise) then the output will only include the dry, unprocessed signal.
At 0 (central) then the output will include equal amounts of the dry, unprocessed signal, and the generated sub-bass.
At 100% (fully clockwise) then the output will only include the generated sub-bass.
MIX LOCK (🔒)
When MIX LOCK is enabled, the MIX control value will be frozen when switching between presets.
The plug-in provides additional, global filters on the output that are applied at the output.
FILTERS GRAPH and FFT
This graph displays the output signal before and after being filtered. Drag the filter flags to set the cutoff frequencies. Toggle the filters in or out with the button at the bottom of each flag.
The signal in the background shows the input to the filters. The signal in the foreground shows the output. This allows you to visualise what is being removed.
LOW FILTER CUT-OFF
The LOW FILTER CUT-OFF sets the cut-off frequency for the high-pass filter, which removes low frequency content. You can use this parameters to control or naturally dial back your sub-bass after you've generated it.
HIGH FILTER CUT-OFF
The HIGH FILTER CUT-OFF sets the cut-off frequency for the low-pass filter, which removes high frequency content. This is useful when using SubGen on bass tracks, since you can quickly dial out high-frequency content and clean up your mix without reaching for a separate EQ.
SubGen comes with 4 sub-harmonic generators, each with a configurable frequency, bandwidth and amount. Each band defines the frequency range in which to generate sub-harmonics, and the level of sub-harmonics to introduce.
For example: to generate frequency content between 20 and 40 Hz, you should create and enable a band in this range.
How does the algorithm work?
Simply set a band to cover the frequency range where you would like to generate sub-bass frequencies.
Bass frequencies are then generated in this band by inspecting the frequency content of the signal an octave above. This content is then filtered to isolate the fundamental frequency, and use this to generate a new signal at half the frequency.
The resulting sub-bass generated by our algorithm is a sine-shape, but inspired by the original signal - making for an effect that blends naturally with the original.
Each band has multiple configurable parameters. The BAND GAIN, FREQUENCY and WIDTH are controllable both from the graph above, and the controls below.
BAND IN (⏻)
Toggles the sub-bass generator band in or out.
The gain of the signal generated by the sub-bass generator band.
The center frequency at which to generate sub-bass content.
The width (in octaves) of the band in which to generate sub-bass content.
BAND LISTEN (🎧)
Solos the generated sub-bass signal for this band.
The graph displays the generated sub-bass signal for all of the bands. Each band is colour-coded.
The left axis shows level (dBFS), the right axis shows gain (dB) and the top axis shows frequency (Hz).
The node (○ or ●) indicated the center frequency and gain of the band.
When you mouse over a band or any of its corresponding controls, it will become focused. This is indicated by the node becoming filled (●) and the corresponding band name will become highlighted below.
Interacting with the graph
To change the band's gain and frequency, grab a node and drag it around.
To change the band's gain only, drag the horizontal line up/down.
To change the band's center frequency only, drag any area between the two vertical lines.
To change the band's witch, drag the either of the vertical lines.
The signal in the foreground (with the faint outline) shows the FFT of the generated sub-bass frequencies in that band. The signal in the background shows the FFT of the original signal.
The example above shows band 2 generating sub-bass frequencies around 40 Hz, where the original signal only contains frequencies above and around 100 Hz.
Shaping (Drive and Compress)
The bottom section of the GUI features several simplified controls for shaping the final output, pre-mix.
Bypasses the drive stage in/out.
Adds harmonics to the generated signal, to add 'glue'.
The drive stage features 3 tailored saturation characters:
- 'Bass' - 70s transistor-style (mostly 3nd order) drive and grit with strong harmonic depth, mild overtones, med-high wet/dry blend with aggressive overtones for adding bite to bass
- 'Kick' - 60/70s transistor-style drive (blend of 2nd and 3rd order) with lighter harmonics and subtle overtones for adding distortion to kicks
- 'Pre' - 50s valve-style overdrive, with smooth and subtle overtones, emulating a valve pre-amp (mostly 2nd order) and ideal for sources other than bass and kick
Toggles the compressor in or out.
GAIN REDUCTION METER
Displays the current amount of gain reduction being applied to the signal.
Applies compression to the generated sub-bass signal. For example, you can use this to let transients through by compress or level-out the generated harmonic content.
The COMPRESS AMOUNT is a compound control that sets both the threshold and ratio: as you dial in the amount, the threshold reduces from 0 to to a maximum of -40 dBFS, and the ratio increases from 1 to 8.
The compressor has a relatively short fixed attack of 5 ms and release of 20 ms (for tightening the signal with the attack, while retaining excitement and aggression on the release).
The knee of the compressor is fixed at 6 dB for a transparent transition between pass-through and compression.
Applies a make-up gain post-compression.
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 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.
