Question about Razer Huntsman V2 Tenkeyless

Hello. I've just checked Synapse and I don't think you can (I've checked several sites too and several users have complained). The keyboard has internal memory, but I can only find the option to save the key configuration (including macros), but not for RGB effects.

If the problem is that you don't want bloatware, I can't help you (there is alternative RGB software, but you still have to install something on your computer). On the other hand, if you've got Linux, there's the OpenRazer project, and on Mac you've got the razer-macos project (both on github).
