Cool logitech G19 mod!

[Ace Modder]

Hey guys

Thought I would share this for anyone with a G19 keyboard. (You can speed up or slow down the pulse too)

To enable this you just load the G key profile software. Set the profile you want to colour pulse. Go to the Edit Menu then script editor.

Add the following code, and save. Then hold down right ctrl button and select the M1 button. (Holding down right shift and pressing left shift then speeds up pulse, and holding right shift and pressing the left crtl button slows it down)

The controls are explained on the first few lines of the coding you have just added.

I do like that effect, is this mod only limited to the G19? Can it be used on other keyboards? IMO the G19 is waay too overpriced

Hi, sorry for bringing this back up, but does anyone know how I can change the code so that it cycles through a spectrum at roughly the same speed as my mamba docking station?
