Razer Synapse 4

So today I was prompted to upgrade to S4, and as a result I've spent 2 hours setting it, only to roll back to S3 in the end.I’m so frustrated and angry… Why would they recommend it if it so buggy?!No matter what I did, it couldn’t normally transfer my Studio profiles with that migration tool. Almost everything was lost. I even tried importing saved profile files, but the new Studio saw only one profile in them. Is it really that hard to have backwards compatibility for importing?! Especially since they have that migration tool, so the basic logic is already there.I also could not make Synapse profiles to autoswitch when switching to Excel (which is one of the main reasons for me to using this product in the first place): when I tried to add it to the linked games (why not finally rename it to games/apps?!), nothing happened. After some time and no explanation, when I opened this menu again - it mysteriously appeared there. but now I could not delete it been linked to one of the profile

Hey there, I moved from Synapse 3 to 4, since it was recommended.😅  I have a Razer Mambe Elite, which I sticked “Mouse Skates”, but its an awesome stuff. Its lifting my mouse a bit, so I had to calibrate it giving me a “lift off” value of 3.I was happy with Synapse 3. Everything worked, after restarrt of the PC the calibrated mouse pad was loaded automatically. Now with Synapse 4, I calibrated the mouse pad, everything worked fine. Lift Off value is at 3.BUT everytime my PC is restarted or after shut down, or standby, it seems that the calibrated pad is not loading, although the green checkmark is correctly set:And yes, Synapse is set to start with WindowsSo I have to open Synapse, and use a second standard mouse to click on standard and back on my calibrated “Mouse Mat” so my Rzaer Mamba is working correctly.Any advice? 😃Thanks alot

Hi, as I said in the title, my Razer Nari mic keeps getting lower by itself , only with Synapse 4.It’s kinda strange, it seems like my pc is possesed lol.I reinstalled Synapse 3 and I don’t have this problem anymore, but the audio seems muffled.

Everything about the audio visualizer works and reacts to audio fine except the very bottom row of keys and strangely the very right column of keys on my keyboard don’t light up. As if its a bottom right corner boarder. However the left column and top row of keys light up and react fine.

As you can see in the attached photo file, the device is turned off and cannot be connected. All the methods the support page has told me will not fix this.

I’m unable to enable the Mode toggle to control the fans attached to my Razor PWM fan controller. When I click the switch to enable it, I just get a blank window. This started happening when I switched from Synapse 3 to Synapse 4.

How I can find this file? It isn’t in that folder in Error Message! Thanks in advance!

Just updated from Synapse 3 to Synapse 4 and after a fresh install and restarting my PC my Naga Trinity will randomly act as if my scroll wheel is being rolled up/down. Only fix I have found is to change the profile in Synapse 4 for the mouse but this is only temporary. Anyone else experiencing this?

I'm experiencing an issue with my Razer DeathAdder V3 HyperSpeed. On Razer Synapse 4, the battery indicator is stuck at 100%, no matter how long I use the mouse. I've tried unplugging and reconnecting the dongle, reinstalling Synapse, and even switching to a different USB port, but the problem persists.Has anyone else faced this issue? Are there any fixes or workarounds to ensure the battery level is displayed correctly?

This is something I have talked about in the discord and with customer service and I am so glad you added this to the update. I get a git like version controller for my settings, my games can be played without logging in. The cloud requires a log in and that is super fair, but thank you so much for letting me be able to be offnet and enjoy the game pad I have. I have a Tartarus V2 and have put many hours on it, thoroughly enjoying the hardware and Simple software. You peeps also separated rgb control from other firmware which I greatly appreciate as well. Thanks for the great work and I look forward to seeing what y’all come up with next. ty ty cheers.  

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

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...
