released: SlickEQ

TDR SlickEQ main flat

TDR VOS SlickEQ is a mixing/mastering equalizer designed for ease of use, musical flexibility and impeccable sound.

Three (and a half) filter-bands arranged in a classic Low/Mid/High semi parametric layout offer fast and intuitive access to four distinct EQ modes, each representing a set of distinct EQ curves and behaviors. An elaborate auto gain option automatically compensates for changes of perceived loudness during EQ operation. Optionally, SlickEQ allows to exclusively process either the stereo sum or stereo difference (i.e. “stereo width”) without additional sum/difference encoding.

In order to warm up the material with additional harmonic content, SlickEQ offers a switchable EQ non-linearity and an output stage with 3 different saturation models. These options are meant to offer subtle and interesting textures, rather than obvious distortion. The effect is made to add the typical “mojo” often associated with classy audio gear.
An advanced 64bit multirate processing scheme practically eliminates typical problems of digital EQ implementations such as frequency-warping, quantization distortion and aliasing.

Beside the primary controls, the plug-in comes with an array of additional helpers: Advanced preset management, undo/redo, quick A/B comparison, copy & paste, an online help, editable labels, mouse-wheel support and much more.

SlickEQ is a collaborative project by Variety Of Sound (Herbert Goldberg) and Tokyo Dawn Labs (Vladislav Goncharov and Fabien Schivre).

  1. Thankyou for this, and all your past and future efforts.
    I will put it to thorough use in the coming weeks and report back.
    Big Love Herb!

    • thank you!

      • I’m loving it. Nice sound, useful colors, and variety.
        I LOVE the volume compensation feature, it makes judging the curve and the character a breeze!
        Can I ask how you moved your code from synthmaker/flowstone? I’m still in early stages of DSP learning and I was worried that the code language in it is too unique to be useful elseware, so I’m concurrently learning java too. I take from this collaboration it is transferable then? as to my knowledge flowstone is still a single precision (and vst only) evironment?
        Thanks again.

  2. What the?!1 You guys are killing me…

  3. Hmmmm why so good for so free ?! No way, thank’s guys …

  4. now I can’t wait to get home…….. ^_^

  5. Thanks to the new dream team for this beautiful EQ !
    Like probably many of you, I have lots of good EQs to choose from already, this one stands out however, both in terms of subtle character options that always sound “expensive” and an incredibly well thought out UI, rivaling the very best commercial products both aspects.
    Sure hope you guys will get along fine and we’ll see more fruits of this winning collaboration in the future !

    habe schon einige eq plugins gekauft oder getestet, bin von deinen plugins immer wieder beindruckt, wirklich durchdacht. diese zusammenarbeit konnte ja nur gut werden. danke

  7. Thank you very much .. the “SlickEQ” is realy great…!

  8. Why the change to an installer? It was a lot better when we could just drag the DLL into the VST directory, now we’ve got to select two directories and make a shortcut in the start menu that I can’t imagine anyone using.

    • Agree on this, installers for me create a discomfort, a feeling of that my system is being manipulated behind the scene where as dll is just a file, and all actions with it are transparent. Well, I’m a bit of a paranoid perfectionist and I guess installer is the input of the TD philosophy.

      • susiwong says:

        Fwiw, I wouldn’t need an installer either, but with 4 different plugin formats on PC already, and more to be added soon, a person not doing this day in-day out might easily be overwhelmed by all those paths dictated by Windows and the various hosts.
        And this installer is squeaky clean, it only puts the plugins in the correct places, no fishy registry entries or “added value”, and it uninstalls perfectly, too.
        Maybe it’s not such a bad idea after all ?
        just saying,

        • As far as I can tell all it’s installed is an uninstaller, a changelog, an icon, and the DLL. I don’t need that other trash, I’m interested in the plugin. I don’t need a program to put a DLL in the VST directory with two (one for the DLL, one for the uninstaller for the DLL as far as I can tell) list-view file browsers that are the worst things to navigate, I don’t need yet another one to take it out. It’s slower and bulkier and boosts the file size compared to a ZIP, RAR, or 7z of just the plugins. The installer can’t possibly be to improve the user experience so I guess it’s for pushing the new brand but I’m going to be looking at their logos every time I use the plugin. There is no reason for this that makes sense to me.

          • The “no installer” download button has arrived, such love and compassion for us, clean system addicts! Thanks to the dev team.

            • That’s great so that no one else has to put up with the installer but I still want to know why there’s an installer in the first place. I seriously can’t figure it out. It’s objectively worse in every way imaginable unless somehow there’s a user that, despite knowing that you can get new VST plugins, does not know how to navigate to the VST plugin directory.

        • It’s all about trusting the developers then heh, my paranoia eased :)

  9. Ok, so I just HAD to come back here and comment about the switching of EQ curves and color shifts of the GUI.. such a nice touch!!! I am amazed on how simple the layout is and how easy it is to start tweaking, but at the same time, it can get quite complex.. It does seem to require a little bit more CPU than the other Bootsy plugs, but from what I am hearing (and experiencing) right now, it is well worth the minor CPU hike..


  10. Ignaceland says:

    unbelievable, have to try this thing out! You guys are amazing!! Congratulations, That’s a great Team!

  11. Wow, i see 64 bits. Thanks, bootsie and td guys.


  13. Well done guys. :)

  14. recursively burning bear says:

    too bad that we live in different places, can’t give you a real hug for this, but be sure that all that love that your work generates comes back to you in one form or another :)

  15. Nothing left says:

    I have a question: When I turn the EQ Sat on, why does the Calibrate button light up?

  16. Thanks so much guys!!
    The auto-gain is one of the most useful features in a plug-in in a long time for me!

  17. Dave iLL says:

    Hi. I am not having any luck installing this on my Mac. I get a script error.

  18. Thank you so much!
    Stunning VST!
    I just dropped this EQ onto a vocal and percussion track and it made a very smooth improvement.

  19. Dave iLL says:

    Thank you guys for the fix. It now installs with ease on my Mac. You are the best :)

  20. Thanks Bootsy. ‘will check it out soon. Cheers.

  21. Cortex9N says:


    Thank you for all the hard work guys! You and your plugins are inspiration for all of us.

    Keep up the good work!

  22. Incredible! Big thanks to the three of you!

  23. I get some massive slowdown when silence is being fed through the plugin. with eight instances up, it’s enough to lag my mouse cursor! is this a denormal issue? it seems pretty serious.

    I can recreate this by starting a new project, creating an empty track with SlickEQ on it, setting it to Silky non-linearity, and duplicating the track several times.

    32bit VST on 32bit Reaper on 64bit Windows. AMD Athlon II X4 620.

  24. Thanks a bunch for all your offerings.

  25. The Process mode button doesn’t seem to work using Reaper as host(Windows 64 bit version). Everything else works and sounds great.

  26. Slick EQ sounds great, thanks Fabian and you and everyone involved. I used in a mastering situation and it worked fantastic. The mid band opens up quite well, The American and German emulations were very interesting. The German was wide with huge harmonic boosts. I could not use the low and the high bands at all. It wasn’t useful on my chain.

    Congrats again … great work mates… Cheers.
