Tartus v2 and Synapse 4 issue with Sept 2026 update

My Tartus v2 wont let me use my custom key maps after the latest update. It says I need Synapse 4 running, which it is. I tried the repair options, I also tried a clean re-install. But nothing. I use this for both work and gamming, so this really has me in a bind as it was apart of my workflow. Any help would be appreciated. Im on windows 10 but with the most updated security features.

    I am experiencing the exact same issue and have done the same troubleshooting steps. Also use it as part of my own workflow as well. Chiming in to hopefully get some more visibility. I’m on Windows 11, fully updated.

      My movement pad on  my Tartarus v2 stopped working with the latest update.  I was actively playing a game with it earlier and it was fine.  I came back to the computer later and noticed that Synapse had updated, and now it no longer works.  This isn’t the first time a Synapse update has broken keybinds, sadly.

        I’m experiencing the same issue as well. Tartarus d-pad was working fine earlier, updated Windows and now it’s unrecognized by Synapse 4. The only solution I’ve found was to uninstall Synapse entirely and remap all the keybinds in my games to match the default Tartarus output. Really hope they fix this soon as the default output is awful.

          For the d pad, a workaround that I found in a thread last from last year is to change the d pad to the 8 directional layout, then manually map the up, down. left, and right directions to the arrows on your keyboard.  I had to make macros (up arrow + left arrow, etc.) for the diagonals.  This actually works, but the movement is still kind of janky compared to the default movement.  If you don’t need diagonals you can disable them. For some reason this only works on the 8 directional and not the 4.

            m having the exact same issue with my Tartarus V2 since the latest Synapse update.

            I was playing without any problems until the middle of the afternoon. I started playing again later in the evening and suddenly noticed the issue, even though I hadn’t changed anything in Synapse.

            After several tests, I can confirm that the correct custom profile is loaded and that the key mappings are displayed correctly in Synapse.

            I performed a complete uninstall of Synapse and Chroma, then reinstalled everything from scratch. The Tartarus V2 is now detected correctly, but the problem remains.

            I am currently using Synapse in Guest Mode, so no cloud profile or account synchronization is involved.

            The issue is specifically with the D-Pad in 4-way mode: the four directional inputs are not registered at all, even outside of WoW. The other mapped buttons on the Tartarus still work normally.

            If I completely close Synapse, the D-Pad works again with its default behavior, which confirms that the hardware itself is working.

            As a temporary workaround, I switched the D-Pad to 8-way mode and created macros for each direction and diagonal. This works, but movement is noticeably less smooth and more jerky when changing directions compared to the normal 4-way mode.

            I really hope Razer releases a patch quickly, because this issue appears to have been introduced by the latest Synapse update and makes the D-Pad much less comfortable to use for movement in games.

              Zeraphae and I are experiencing the EXACT same issue.. I cannot resolve this by myself it seem. 

                Add me to the list of people experiencing this problem. Not cool, Razer. Not cool.

                I had the same problem, went through a million steps, was in contact with support. This eventually (for now) worked, give it a try. 

                 

                EDIT: No forget it I am an idiot for thinking this would work. It made the D-pad work, but none of the mapped keys work, even though synapse shows they should be. Still working on a solution.
