Hey everyone,

I recently bought a Liquid mix 32 for very cheap on ebay on a whim – as a discontinued product that’s 8 years old I figured it may not work anymore so I took a chance on it. I can happily confirm it works on 64bit Windows 8.1 with the latest version of Pro Tools 11. It’s a little tricky to get working and there’s no info online, so I thought I’d make a quick guide for anyone attempting to get it to work on a modern computer. The unit sounds fantastic and is well worth the hassle!

This may work on Mac, and I have a Macbook air I intend to try it on, but this guide is primarily aimed at Windows PC users using Pro Tools.

What you’ll need:

1. A computer (obviously) – for reference I’m running an ASUS Z87-K, 16gb ram, Windows 8.1, NVidia GTX 760, 128gb system SSD and a bunch of larger HDD’s for files and such.

2.A TI chipset firewire card– some TI chips are better than others apparently, my card chipset is TSB43AB23, which is working well, so I recommend this one.

3. If you have a firewire interface (I have the Liquid Saffire 56) you’ll need to run this on a separate firewire card as the Liquid mix will not work otherwise (you’ll get dropouts as it’s a FW bus hog)

4. Any firewire cable will work for the LM, I use a cheap ebay one. You do not need the power supply for the LM.

5. Windows 8.1 with the latest updates and Pro Tools 11 with the latest updates.

6. Bluecats Patchwork – this plugin enables you to run VST plugins in Pro Tools. It’s an awesome, affordable plugin that is worth having anyway, but it will allow you to use the Liquid mix VST in PT.

7. Liquid Mix software version 3.0 with all the emulation files.

8. A copy of jBridge – this will bridge the 32-bit Liquid mix VST to 64 bit so you can use it with Bluecats Patchwork. You can use the demo to try it out, but it’s under £20 to buy so it’s very affordable to purchase.jBridge ( for Windows ) | J’s stuff

Here’s how to install the Liquid mix:

1. Run the LM installer. Do not connect your LM at this point. When the installer asks you to connect your LM, open task manager and close the LM installer.

2. Open your ‘charms’ menu in W8.1 by hovering your cursor in the right hand corner of your screen. Go to settings > change PC settings > update and recovery > recovery > advanced startup > restart now. Your PC will restart and you’ll be given a list of options. Choose the one that disables driver signing. Your PC will reboot with driver signing disabled.

3. Go to My Computer > C:/ Program files (x86) > Focusrite Liquid Mix > driver – you’ll see a file in that folder called ‘lm1394.cat’ (if windows is hiding your file extensions then look for the lm1394 file that is labelled as a security catalouge, or go to view > show file name extensions)

4. right click on ‘lm1394.cat’ and select install. This will install the driver for your LM – it’s an unsigned driver that won’t install unless you install it manually this way.

5. You now need to change your firewire card the LM is running on to use legacy firewire drivers. Windows 8.1 doesn’t come with these so you need to manually download them. Go to Download Update for Windows 8 and Windows 8.1 for x64-based Systems (KB2970191) from Official Microsoft Download Center

6. Once downloaded run the installer. After that go to C:\Program Files\1394 OHCI Compliant Host Controller (Legacy)\x64_driver and right click on Legacy1394.inf and select install.

7. now go to device manager and find your firewire card. It will be under ‘IEEE 1394 host controllers’. Right click on your firewire card and select ‘update driver software > browse my computer for driver software > let me pick from a list of device drivers on my computer. You should see a list of drivers, select that one that says ‘(Legacy)’ at the end of it.

8. Your Liquid mix is now installed and running! Run the LM software and it will connect the hardware controller – the default options (32 tracks, 512 buffer) should be fine but if you need to later on you can play around with these.

9. Now to get it running in Pro Tools! Install Bluecats Patchwork and jBridge. Run jBridge.

10. in jBridge, choose the ‘I’ll be using a 64 bit host’ option. Hit the first button below the checkboxes to locate the LM VST’s. They’ll be in C:/Program Files (x84) > Steinberg > VST Plugins > Focusrite. Select the ‘Focusrite’ folder. Then hit the bottom button in jBridge to choose a separate folder to save the bridged VST’s to.

11. Load up Pro Tools 11 and add Bluecat’s Patchwork as an insert on a track. Go to ‘Load VST’ and locate your bridged LM mono vst. When the LM vst loads up you’ll see the jBridge logo at the bottom of the plugin window. Next to that is a settings button. Click it and you’ll see a window appear with lots of checkboxes. Check the box that says ‘Run in existing auxhost’ – then restart the LM plugin. Do the same for the stereo LM vst. This is a vital step as otherwise you’ll only be able to load one instance of the LM plugin, and the LM hardware will disconnect if you try to run another instance.

12. That’s it! Enjoy your Liquid mix One thing to note is that only the first instance of the plugin that you load can be controlled by the software – every other instance can only be controlled by the hardware. If you try to change parameters via the plugin window PT will throw up CPU errors. It’s an odd bug but entirely workable, plus it’s more run to use the hardware controller anyway

I hope this helps some people! I had to figure this all out by myself, so hopefully this will save others trying to get it working in Win8/PT11 some time Any questions give me a shout and I’ll try to help!


  1. Any success in getting this to run on Mac? LM’s are going pretty cheap and I’m thinking about picking one up to use in PT11

    • I’ve yet to try yet Travis sorry – my main rig is a PC – I have a Macbook air which I use on the go, but don’t really do much Pro Tools work on that so I’ve not had the need/time to check it out. I’ll try and get round to it this week!

  2. Just picked one if these up 2 days ago and can’t get it to work with my Mac for the life of me. I emailed Focusrite with hopes that they can help but it is discontinued so I don’t know how support is on it. There’s DMGs for the emulations and they can’t be recognized when mounted or opened and when I put them in the folder that LiquidMix tells me to it still says emulations cannot be found and to place them in the same folder again. I’ve scorned all the forums on this thing to much unveil and I can’t even open it up within any DAW after installing.

  3. Hello,,,I have use Pro Tools in many years with very little issues, then i bought a Focusrite Liquid Mix 16…
    I use windows 7 X64, and PT 9.6…
    And i could not use LM 16 in PT, all i get from PT whas “Incrase CPU usage limit” wich was directly a problem, cause i have max on CPU,,i have tried to solve this issue for a long time (5 mouths) i search on Google with no solution,i have done everything that people proposed, never worked..
    ,BUT, one day i saw that my project whas in 16 bit, so i change to 24 bit,,and suddenly,,LM 16 works perfect in PT,,i check CPU use in PT and no CPU loading when i inserted LM on a channel..
    This issue is apperently not something Focusrite know, cause i get no support from them..
    I dont know if this comment is to any help to some one…

    • Very helpful info, thanks!

    • Hej Jörgen!
      Jag köpte mig oxå en LiquidMix som funkade fint med mitt ProTools 10. Gillar Liquid mix emuleringarna skarpt. Dock får jag inte igång LiquidMis sen jag uppdaterade till Protools12. Kör MacBook pro/ Yosemite.
      Min fråga är om du vet hur man får igång LiquidMix i ProTools12?
      Kan man gå via ex BlueCat patch? Jag är ingen expert på detta men hoppas det finns ngn lösning på problemet.
      Tack på förhand

  4. Two problems…

    1) – I can not right-click install the ‘lm1394.cat’ file. Install is not an option in the right-click menu. I can do the following:

    View Signature
    View Certificate
    Install Certificate
    Choose between “Current User” and “Local Machine”
    Choose “Automatically select the certificate store, or you can store based…”
    Press “Finished”

    At that point it says the import was successful. Is that the same result?


    2) The KB2970191 download fails to install. I found many people online also having trouble with that msi file. When runs it instantly closes and no files are installed. Any idea where those files should be placed, and what else I would need to do to do that install manually?


    • I got it to work, maybe this will help someone else:

      If you can not run the KB2970191 download.

      1) First extract the files from the msi installer package.
      2) Throw out all the ones with “2” in the title. (The files with 1 worked for me so I didn’t need the ones with 2 suffix).
      3) Rename each of the remaining four files by removing the “_” prefix and the “1” suffix.

      Double click on the legacy1394.cat file (the catalog file)
      View Signature
      View Certificate
      Install Certificate
      Choose between “Current User” and “Local Machine”
      Choose “Automatically select the certificate store, or you can store based…”
      Press “Finished”

      Right-click the Legacy1394.inf file
      Select install
