Razer Synapse 4

In these recent updates this feature got bugged, it still works just not as intended. to verify this I went back to synapse 3 for testing purposes and there it worked as intended.I like to use the M1-M5 buttons as my very specific controls for some games and this bug completely breaks it,For example, I like to bind my M3 to Alt  (which is a jump key for the game in question), now when I use the regular Alt key I can jump while moving to the right (pressing right arrow key). Problem is that when i rebind my M3 to work this way, it just does NOT do the same thing. I tried all the available options, in any configuration I might add, be it key recording, alphanumeric or any other option) it just won’t work as the actual key anymore. Any thoughts/ideas or workarounds would be very helpful.  I use a Razer BlackWidow V4 Pro

Hi everyone,I just purchased a Viper V3 Pro. The Dongle sometimes might not show the light indicating my mouse battery after I open my computer. Sometimes when I wake up my computer from sleep the Dongle also showed no light of my mouse battery as well; but the mouse is still working. Then, I have to unplug the Dongle and plug it again and it works fine. And sometimes I cannot wake up my computer from sleep using the mouse and the dongle as well; sometimes it works sometimes it doesn’t. I don’t experience any connectivity issues during gaming or using. It’s just something happen at the beginning like when I first start my computer or waking up from sleep oor trying to wake the computer from sleep. I already reinstall synapse4, update firmware, pairing etc, but it still happens. Is this a software issue or hardware issues? Should I RMA?

I’m currently using 2024 Razer Blade 14 and updated to the latest version of Synapse 4 on May 7th. Immediately after the update, I started experiencing the following two issues: Since the update, there's a bug causing the volume of THX Spatial audio to be lower than the set level. I usually set the volume to 8 with THX Spatial audio enabled. However, after restarting the laptop, even though the volume setting still shows 8, the audio output is noticeably lower. Upon investigation, I determined that Synapse 4 is causing this issue. Changing the sound setting in Synapse 4 from THX Spatial audio to Stereo and then back to THX Spatial audio temporarily fixes the issue, restoring the volume to its correct level. There's also a firmware update notification bug. When opening the Synapse 4 app, I receive a notification indicating that a firmware update is required, providing the following online link: https://mysupport.razer.com/app/answers/detail/a_id/13930. This link directs me to the BIOS

I have been experiencing this issue where some of my keys on my “BlackWidow V3” keyboard stop working sometimes but in a super weird way. I’m pretty certain that it’s and issue with Synapse 4 because the key’s immediately start working again after I focus the Synapse application. From what I noticed is that it only effects lower case “h” and “c” and possibly “k”. When the issue occurs I can type the uppercase variant’s, of the before mentioned keys, just fine but still get no input when lowercase until I tab out of the game and refocus the Synapse application. It makes me wonder if this issue could be caused buy “Full-screen Windowed” games/applications because I stumbled into similar Issue while using OBS and an eye tracker where the stream video would bug out the second the game was tabbed back into (Counter-Strike 2). Some other person experienced the same exact issue but in Call Of Duty. So in both of those games, they have quite a few compatible issues caused by their Anti-Cheat s

MY HEADSET DOES NOT APPEAR IN THE SYNAPSE PROGRAM, WHAT SHOULD I DO?   

headphones still cant load, profiles are still broken, and it crashes every 3 seconds. no Im not sending logs or anything, the last time I did that I was told there is nothing wrong. waste someone else's time.

Ive tried multiple times to install, reinstall, clean, etc.  All the suggestions provided including trying to install previous version.  No matter what, synapse doesn’t recognize the laptop.   

All Cryo Pro Ultra Resolutions within the Synapse 4 Camera Processing tab are for NTSC - ie they are all 60/30 FPS. I am in the UK and require resolutions for PAL - ie 50/25 FPS, for camera input into the software I use.Although I set the image anti-flicker to 50Hz, as used by PAL, the Synapse resolutions don’t change to suit.Any chance of an update or info’ how to use the camera on PAL sytems?

Currently, when a macro includes a long delay (e.g., 90 seconds), it becomes impossible to interrupt or restart the macro during that delay. The macro must finish the full wait time before any new input — even from the same hotkey — can trigger a new loop or restart the macro. This behavior limits responsiveness and flexibility, especially in scenarios where the user needs to adapt mid-loop. Please consider adding functionality to: Interrupt or reset a running macro immediately, regardless of how much delay time remains. Optionally allow delays to be non-blocking, so pressing the assigned macro key again can cancel or restart the macro on demand. This would dramatically improve the responsiveness of macros with long or variable delaysThank you for your work and continued updates to Synapse!

Hi. I’m bought Razer Naga V2 Hyperspeed and never use Razer before. I create Macro with “5+Left Click” and assign to mouse button with Play while assign key is press ( I think it’s same “repeat mode” in LG Hub).I found if i press hold macro button then release , sometime it stop at “5” left click not come after that. on LG Hub if i press hold then release macro it’s always call “5+Left Click” every-time no interrupt. Do I make something wrong with Synapse 4? or it’s normal thing for Razer Synapse 4?

When I download synapse 4 and transfer my profiles, my macros that worked when I was using synapse 3 do not work correctly and are imperfect. For example, in a game, when I set the weapon to not ricochet, it does not control the weapon ricochet correctly, what is the reason for this and how can I solve it? 

The problem is there no delay when i press media up first register and the following registers, so unless i click and release real quick, it raise or decrease volume by 4 level instead of just 2. This was not like that back when i was using Synapse 3. It happened with synapse 4. Razer keyboards (especially with Synapse 4) often send rapid repeat signals for media keys (volume up/down), with almost no initial delay — unlike most other keyboards, which typically have a built-in delay before repeat kicks in (just like regular typing keys).Synapse 4 lacks a setting to adjust repeat rate or debounce time for media keys — unlike some other manufacturers (e.g., Logitech with G Hub or QMK-supported boards). 

I don’t know if it’s Synapse 4 bug/feature or my specific problem, but as it happened after I switched to Synapse 4, I’ll post it here:During Windows logon keyboard lighting is completely turned off. It makes it difficult to enter passkey in the dark. It wasn’t a case with Synapse 3.Windows 10 / Huntsman TE (connected via USB hub)

I want to run bot SignalRGB and synapse simultaneously, since each of them had features other doesn’t. I forced to sacrifice periphery control for getting rid of that insane strobe, I receiving, because of chroma overriding. That would be a massive QoL. Chroma (even via razer ARGB hub) doesn’t give that much of control for my components such as proper AIO fans positioning or RAM/GPU strips, while also has no way to build a fully custom simple HTML/XML file unlike Signal, forcing you to use that atrocious interface for component interactivity. I’m uncertain about my further brand support, since it’s central control software sabotages brand ideology as aesthetical and high-perf products for average consumer. Design team work is great, QA and Software teams results are questionable. 

Installed Synapse 4. The Alt button stopped working (round over the stick). The installed macros are not launched, it does not respond to clicks.no problem with Synapse 3. upd . The problem was solved by rebooting and transferring USB

Good day 

Hi! My mouse is displayed as a black version. Serial number is also displayed as NOSERIALNUMBER. How can I fix this issue? 

I have the new Razer 16 inch with nVidia 5090 graphics card. Unfortunately, the manual fan control does not work in the Synapse 4 software!I can set all the curves manually the way I want. And what is completely bizarre is that the theoretical values are even displayed at the top of the hardware monitor.But: The fans don't do what they should do! Even when the display shows 0 revolutions, you can clearly hear both fans. Even if the CPU and GPU temperatures are below 45 degrees.If I set the curve to maximum, nothing changes, the display then shows 5,000 rpm, but the noise doesn't change! So they just keep spinning as before.If I set it to automatic, everything works as it should. Even when a fixed number of revolutions is set. However, as the lowest value here is 2000, this is too loud for me in a quiet environment.I wrote to support about this, but all I got were completely useless replies asking me “about the type of noise” and asking for videos that I couldn't provide within 24 hours

It never goes to zero. It always fluctuates between 0,1 and 2 percent. Why? What exactly is it doing in the background that it requires constant work?

Hello, A long time ago I bought a razer Naga.I created a lot of macros and profiles, to play video games at home but also to bring my mouse at work and being faster.At work I just had to plug the USB receiver and I could use all my 12 macros (and more with hypershift) without any problem.But now that I installed synapse 4, nothing works, it says macros require Synapse but it wasn’t the case by the past.Will it be fixed later ?Can I fix it by myself ?Why my macros aren’t anymore stored in the mouse too ? It’s really disappointing that everything was working and now all my macros for work are useless :( RegardsLux

I am having an issue with my laptop and synapse unregister my 1 key, and i do not know what to do about it.I have gone through the fixing steps with my PC to get it to reregister my 1 key, and it works until i open synapse. I have checked my bios checked my system drivers everything is up to date and working properly, my settings are in the right presets for the 1 key to work properly. I did do a drivers test by deleting all HID keyboard drivers in the device manager and reinstalling them when ever I do this my 1 key will work properly again on my keyboard and my tartarus v2 but as soon as synapse opens or if i open synapse my laptop instantly forgets the 1 keystroke and ill have to uninstall the drivers again and repeat the process to get the key to work again, but its just a never ending cycle of deleting keyboard drivers reinstalling them just for synapse to reopen and make my pc forget the keystroke. Am i missing something? what am I to do to fix this issue? PLEASE HELP!!!

I can't see my mouse in the razer app on mac Sequoia v15.5

Ever since I switched the Chroma RGB app of Synapse 3 to Synapse 4 I have had this issue. The only Razer RGB device I have is the  Razer Hanbo Chroma RGB AIO Liquid Cooler. Basically, I am trying to use the “wheel” quick effect, but nothing happens when I select. After this, I decided to use Chroma studio and add a wheel preset, but the lights seem to be lagging and stuttering but still colorful. When testing the other quick effects that aren’t the wheel, they work, but they are also seem to stutter, almost like the lights are working fine, but at the end of the loop, there is a stutter and the loop repeats. I have a separate Logitech rgb keyboard on separate software and the rgb animations seem very fluid, unlike the pump and fans. Also, just so you know, the windows lighting effects setting is deactivated. Maybe it is an issue with the Hanbo Chroma RGB AIO Liquid Cooler’s firmware and it is somehow compatible with Synapse 3 but not 4, but that should not be an issue, since the hardwa

I have razer synapse 4 and all lights tunf off in razer devices after launching the game. If i stop razer synapse software the lignts turn on again. I followed razer guidelines in order to disable dinamic screen in windows. Can anyone faced this issue?. Thanks
