Softube’s Saturation Knob Is Now Available For FREE On All Platforms!


Saturation Knob by Softube.Softube has announced that their saturation effect called Saturation Knob is now available as a completely free download for all popular plugin platforms. You can now download Saturation Knob as a 32-bit and 64-bit VST/AU/AAX/RTAS plugin, as well as a Rack Extension for Propellerhead Reason.

Saturation Knob has been around for quite a while now (I think that the plugin was first released back in 2011), however it’s availability was always limited to only a few select digital audio workstations. Until today, this rather interesting saturation effect was available for use only in Pro Tools, Cakewalk Sonar, Studio One and Propellerhead Reason. But that has finally changed and we can now use this saturation tool in virtually any host application out there!

Although one-knob style effects are not everyone’s favorite kind of audio tool, I actually enjoy using such plugins because they are well optimized for achieving the best possible results with minimum tweaking. This can often save tons of time during a mixing session. When it comes to compressors and equalizers, you’ll obviously want all the control you can get (although the incredibly simple DC1A compressor is still one of my all-time favorites). But with colorization tools which are used to add some character to the processed audio signal, in my opinion it’s great to be able to use them as simple plug and play stomp boxes.

Anyways, Saturation Knob is exactly that kind of plugin. It features a single knob for adjusting the amount of saturation and it can work in three different modes, depending on what flavor of saturation you’re looking for. And that’s it! This kind of saturation effect might be too simple for some, but I find it a rather useful tool and a great little freebie!

Now here comes the bummer. To install your free copy of Saturation Knob, you’ll need to download a rather large installer first. The installer contains all Softube plugins and they all need to be installed on your machine. After the installation process has ended, you can remove the plugins which you don’t want to use. That’s quite a drawback I have to say, however there’s a possible workaround for this. If you download a free tool called Universal Extractor, you can extract Saturation Knob from the package and skip the installation process completely.

  1. Tomislav, 7-Zip can also extract this file and some people might already have that installed. Extracting is the first thing I try with every single VST-plugin that comes with an .exe-installer.

    • Thanks UserFX, that tip saved me jumping through hoops with the installer. Can confirm (in windows), open the executable as an archive file with 7-zip, navigate to the “$_OUTDIR”directory, then at the bottom should be the saturation knob dll. Extracted it into my plugin directory and it opened up fine in Reaper. Thanks again!

  2. Thats sad. I can deal with registration and newsletters but to I won’t download a 421MB packet just to install a vst that is probably something like 10MB. My internet connetion is slow as hell (ISP fail) and it would take 2 hours to download it.

  3. I just installed it on OS X; the reason it’s such a large installer is because it has some stupid “Softube Plug-in Control” application that installs with the plugins to manage which ones will be available in you host. Kind of like the plugin manager that every major DAW has built in only three times as large.

    • I can confirm on Mac OS X 10.9.5 Mavericks and Logic Pro X 10.0.7 that you can install the plug-in, use Softube’s plug-in manager application to enable Saturation Knob, then delete the plug-in manager application.

      Not that I’d like it even if I did, but I get the point of this plug-in manager if you own every single Softube plug-in. For a single free plug-in though it’s overkill. I also don’t get why the plug-in manager application is over 1Gb on your hard drive for what it does.

      For those wondering the plug-ins themselves are a normal size (10Mb for the AU).

  4. The Softube software installs all of the vendors plugins and you select which plugins to install. Unfortunately the uninstalled plugins are keep on your disk drive as junkware. I uninstalled it.

    • Sure: — link removed —

      Their download is absurd and they better god damn know it. 7MB free plugin, over 400MB of unwanted demos and some b******t program to manage it all.

      Just for the record – I’ve hesitated A LOT before moving to Windows 7, however my impressions so far (after two years of use, I think) are great.

  5. Giving away a free plugin like this is a great way for Softube to market the rest of their products. They make you download them all by luring you in with the promise of something free (and pretty awesome), and then you get tempted and pay for the ones you want to activate.

    Honestly 420mb is not such a huge download… I live in a third world country where a 10mb line is about as good as it gets. I have a 4mb shaped line and the download only took like 40 minutes. At least it doesn’t require an iLok like some other ‘free’ plugins on offer (ahem, Slate!) :)

    The installer allows you to select which plugin to activate, and then it says that “unactivated plugins have been removed.” But for me, that wasn’t the case. It’s nice to have the freebie, but if you don’t want the vestiges of the inactive VSTs, you’ll want to visit the installation directories and clean things out. I downloaded both the 32-bit and 64-bit, so give that a thought too, if you’ve installed both.

  7. HELP!!

    I LOVE this plugin but when I download the RTAS installer Saturation Knob is missing!

    Am I doing something wrong?

    The installer shows other plugins but I just can’t find Saturation knob.

    Anyone know what’s going on???
