The Saturation Knob has previously been available exclusively for Presonus Studio One and Pro Tools users, but today we make it available for users of other DAWs as well. For VST, AAX and Audio Units, Saturation Knob is part of the installer package, which includes all Softube plug-ins. Saturation The free plug-in Saturation Knob is a modeled output distortion that can be used anywhere you need some grit. Use it to fatten up bass lines, add some harmonics and shimmer to vocals. Softube Saturation Knob As simple as can be, and free to boot. With that eponymous shiny knob dialling in the saturation amount, the only other thing to decide is whether to flick the switch right beneath it, which excludes bass or treble from the processing.

It sounds great and it's free...!

Anyone can download the Saturation Knob for free, and get a taste of warm analog saturation in their mixes.

Insert effect or synth module

You can use Saturation Knob as an insert in your DAW, or as a module in our Eurorack Modular platform.

'My response when they told me the Saturation Knob is a free plug-in was — are you nuts? Seriously? It's too good to be free! I use it to make guitars fatter and more aggressive, snares naturally brighter, kicks punchier, vocals warmer. Basically, it's good on just about anything. Saturation Knob should be renamed Attitude Adjuster! If a plugin can be addicting, the Saturation Knob is it!'

• System requirements

  • Mac OS X 10.12 or newer (older OS versions may work but are not tested).
  • Windows 64-bit, versions 7, 8 or 10.
  • Intel Core 2 Duo, AMD Athlon 64 X2 or newer.
  • Screen resolution 1280x800 or larger.
  • 8 GB RAM or more is recommended, as well as at least 8 GB hard disk space for installation (individual plug-ins take less space, while sample libraries may require additional disk space. Specific information available on each instrument's page).
  • Softube account.
  • iLok account.
  • Internet access for downloading installer and managing licenses.
  • iLok generation 2 and up, if you intend to use an iLok dongle for authorizing your plug-ins (note that an iLok dongle is not a requirement).
  • In theory, any 64-bit VST, VST3, AU, or AAX (11.0.2 or higher) compatible host application should work.
    

  However, due to plug-in host differences between DAWs - and our own rigorous testing standards - we only officially test our plug-ins and instruments in the most recent versions of Pro Tools, Logic Pro, Cubase, Live, Studio One, Digital Performer, Reaper and Sonar. Softube plugins are not tested in the non-listed systems, but they most likely work as long as the system requirements are met. We cannot guarantee a solution for issues in unsupported systems.

  Please Note: Softube plug-ins support 64-bit hosts only, and a 64-bit OS is required. Therefore, for example, Pro Tools 10.x is no longer supported (contact support for latest 32-bit compatible instalers).

  Supported sample rates: 44.1, 48, 88.2, 96, 176.4 and 192 kHz, in both mono and stereo.

  The most recent maintenance release of the DAW application is recommended.

  AAX DSP is not in active development, but older products still support AAX DSP. For legacy TDM/VENUE, please see the Legacy Installers page.
