Razer Synapse 4

I tried many times to update Synapse but when I click the button it downloads something, ask for making changes in PC and nothing happenes then, how can I update Synapse then?

Hello all!  Has anyone been experiencing issues with mouse mappings on Synapse 4 not saving for the new Pro Click V2?  Even though I’ve disabled some of the mouse mapping functions on Synapse 4, it still prompts the actions.  It’s as if Synapse 4 has no actual bearing on the mouse mappings? Thanks for any assistance in the matter.

 no really I cant access the settings for my headphones cause the “module” never loads correctly, and when It dones it breaks instantly.

I just upgraded to the latest version… I had my keyboard, mouse, and mousepad all set up with custom colors. It took me a while to get it the way I wanted on my keyboard especially.  Now it’s all back to the default.  Am I going to have to do this all over again?!  How can I get back what I set up before?  Major fail!

does not show notifications when switching profiles in games and on the desktop, is there a solution to fix it?

I need some help please. when ever I restart or switch off my PC and turn it back on, my lighting has been reset to spectrum cycling and my THX is set to off instead of the on setting before shutting down. Strangely enough my keyboard maintains all settings. When I uninstall Synapse 4 and install 3 the headset settings work perfectly, except for some audio crackling every now and then.The headset is a Kraken V3

As of this evening (July 17, 2025), my BlackShark V2 headset's surround sound is no longer working correctly. It seems like there was an automatic update that caused this issue. The audio is completely messed up, making the device unusable. Please investigate and provide a fix as soon as possible.

EVERY TWO SECONDS ITS RANDOMLY CHANGING THE PROFILE FOR MY KRAKEN HEADPHONES AND WHEN I TRY TO OPEN SYNAPSE 4 TO FIX THIS THAT TAB JUST CRASHES AND NEVER WORKS.  IF HEADPHONES AREN'T SUPPORTED JUST SAY SO!!!!!

I just installed synapse 4 on my 2024 blade 18 but when i go to the sounds tab the EQ its all messed up and sometimes it doesnt work, in addition games that have THX profiles (Red dead redemption 2, Half Life Alyx) dont display a THX sound profile but they did in synapse 3 

Before Synapse 4, I had Synapse 3 and it successfully managed to open the files I gave it (using the absolute path). I have upgraded to Synapse 4, synchronized everything I had and when I tried to open a windows file it does not let me. And yes, I have written the absolute path correctly.Here is the error:I have a Razer Naga X mouse for reference

In Synapse 3 I could create a mouse macro that would press down left click and not release it, meaning left click would stay down until I manually clicked the left mouse button.This no longer works in Synapse 4 - the macro releases the left mouse button even without being told to.Is there a way to get this back/could this be re-added to Synapse? Don’t really want to downgrade back to Synapse 3 but I really need this.

Would the community please alert Razer that their threatened date to upload Synapse 4 is unwanted. Synapse 4 has so many bugs, won’t port over so many settings, keybinds, macros, etc. PLEASE IMPROVE SYNAPSE 4 before you drop previous versions!

Hello,Still the same issue with Alexa, which only works with a US account.I am a person with a disability, and I used Alexa on my computer with Razer in version 3 for daily life tasks—something I can no longer do with the new version.I reported this issue months ago (even during the beta), but it feels like the development team doesn’t want to fix it so that it can work with accounts from other regions (in my case, France).This is really bad news for people in my situation—it feels like Razer doesn’t care about disabled users...I am truly disappointed.

So I believe this is somekind of bug, for some reason I can’t select any macros and there is this notification about “Requires Razer Synapse”. I do have the macros on macros tab so at least the profile migration worked, but can’t use any….

I have had the Razer BlackWidow Elite (keyboard) and Razer Kraken Ultimate (headphones) for a few years now. They are both wired, both worked just fine, I used Synapse 3, and maybe a month or so ago switched to Synapse 4. Everything was working, everything was good, until this morning. I booted the PC and in the app it said I have no devices. When I went to the devices section it said that the devices were “Disconnected” and they were grayed out. I tried everything you would normally try: restarting the PC, the app, reinstalling the app, all that stuff, nothing helped. The devices are working I am typing this on the said keyboard, but the Synapse is not detecting them. Anybody knows what’s going on? Also, I don’t have another device on which I can test whether or not the issue would persist...

After a fresh Synapse 4 install both my Naga Trinity and Deathadder V3 Hyperspeed are seemingly stuck “Detecting Device...” There is another thread about this but it was locked after the first response so if they found a fix it’s in private messages… That being said, both my headset and keyboard are being detected just fine. My mice drivers are up to date and my Synapse is version 4.0.86.2411140357. Synapse 3 also had no problems detecting either mouse.  

Please bring back HDR for Dark Room and Bright room for Kiyo ProIn synapse 4 there is one switch HDR ON/OFF and this HDR doesnt work very well - Its very very darkAlso Kiyo Pro in Synapse 4 keeps disconnecting randomly after booting and login to windows  i have to replug the cable in camera.In Synapse 3 everything work fine.i have kiyo pro updated to 1.5.0.1 firmware Mb add some new functions for this camera i saw settings for Kiyo Pro Ultra it has so many settingsKiyo Pro have less settings in Synapse 4 than in Synapse 3In synapse 3 we’ve got auto focus Passive and ResponsiveIn synaspe 4 We’ve got switch for auto focus ON/OFF  

Snaptap on synapse v4 works for every other key combo besides A and D on my huntsman elite keyboard. I have no idea how to troubleshoot or fix this and i did restart my machine. Even other keys paired with only A or D don’t work either. (for example {A, C} do not work. {D, E} do not work. however {C, E} and {D, C} do work.)

Hi everyone,I want to update this thread with some important news — after several months of following up, Razer has finally provided me with a FREE redeem code for THX Spatial Audio Standalone.If you're one of the users affected by the THX Spatial Audio downgrade after the November 2023 Synapse 3 update, here's a breakdown of what happened and how I resolved it.❗ Issue Summary: After the 6 Nov 2023 Synapse 3 update, THX Spatial Audio: Lost 7.1 surround config support Lost game-specific profiles (e.g., Valorant) Lost positional calibration Started showing only Stereo output in Windows sound settings Many users (including me) noticed downgraded audio quality Razer Synapse no longer had the same features t

This functionality was promised to be ready with Synapse 4’s public release, so why it is still not available?

Hi, I'm using the Barracuda X 2022 headset and would really like to see Razer Synapse support added. Please forward this request to the development team.

Why Synapse 3 say: ‘Hey, download Synapse 4, we will keep your profiles and macro’s and put them in Synapse 4 for you.’ Then, you open Synapse 4, and there is nothing there -.-...

In Razer Chroma Studio in the new Synapse 4 update i migrated my old Chroma Keyboard on my Razer Blade 15 and my Reactive Chroma effect fades away so fast and only fades for a milisecond with my actual color then for another milisecond it finishes white.On Synapse 3 it faded actually slow like i picked when i selected slow and it didnt fade to my color and then to white that i didnt even select 

i want to test signalrgb for some time and also keep synapse running. how can i remove light control from synapse ?

DO NOT DOWNLOAD RAZER SYNAPSE 4!!!!! You will regret it!! I downloaded it and nothing on my 2800$ laptop is working properly! They need to fix this problem asap! Pathetic. My keyboard all messed up. Numbers aren’t working, F keys aren’t working. Try to migrate thinking that would fix issues but migrate isn’t working properly. Everything was great in synapse 3. Why changing something that works flawlessly!
