Tartarus V2 Keybinding Broken Synapse 4

StrangeDeucey

Anything I bind to any keys on my Tatarus V2 does NOT work.
I’m trying to change keypad ‘16’ to CTRL and it simply does not work.
I’ve reinstalled Synapse, reset device, etc.

Instead, what Synapse does is apply a virtual ‘ghost press’ of the buttons I’m trying to map to the keypad.
Meaning, any button I map to it, is then somehow being virtually pressed constantly. Nothing I map to my device works at all, and Synapse is to blame.

Despite anything I bind to any button, it is only the default function that happens when pressing any of the respective keys on my device.

I cannot game until you fix this.

I have the same exact problem. I see no one has replied to you in over a month. Just bought the Tartarus V2 yesterday, and none of the key mapping works at all. I’m trying to set key 15 to the space bar, yet it continues to type the default “F” instead. The gamepad simply doesn’t work because of some bug in the software I assume.

Ok after some troubleshooting on my own, here’s what I did to fix the problem. Initially I installed Razer Synapse 4, and could obviously not get any of the keybindings to save in keymapping. I uninstalled the Synapse 4 and went to https://www.razer.com/synapse-3-legacy to download the older Synapse 3. I tried doing the keybinding and it worked. So essentially I’m going to say that they are false advertising when they state that Synapse 4 is backwards compatible with Synapse 3 devices, at least in the case of the Tartarus V2 and Tartarus Pro. Keymapping simply does not work on this device under Synapse 4. Razer really needs to address this issue sooner rather than later.
