Click to expand.Sadly, as others have mentioned, you simply can't do this with the DeathStalker Chroma. It is not a software problem, but a hardware problem. So no software you download will fix it.The problem is the logic board can't talk to each individual LED in the DeathStalker like it can in the BlackWidow Chroma. It can only talk to 3 'chunks' or zones of LEDs at the same time. Therefore, the DS keys do not have individually programmable backlighting. This saves cost.
It is similar to the Tartarus (can only change all the keys at the same time) vs the Orbweaver (can change each individual key).This diagram shows the 3 lighting zones the DS has.
The Razer Deathstalker Chroma is their gaming chiclet keyboard that lights up in a multitude of colors. If you’re familiar with the line, then you should know what the Deathstalker is all about. Not everyone likes mechanical keys for gaming, so Razer’s Deathstalker line of chiclet keys is more akin to a laptop keyboard.
