Eight unique white LED backlighting modes are available on the Z-Machine. Touch mode illuminates keys as you hit them for a more precise looking effect. Wave mode illuminates the key you activate, along with a number of keys around it for a slight ripple effect. Key LED mode keeps the most commonly used keys in gaming illuminated, while Key Mask mode lights only your favorite programmed keys. Demo mode cycles through five pre-set illuminations. Breath mode will automatically illuminate keys in a pattern simulating a pulse. In Equalizer mode, keys will light up when the keyboard detects sound nearby. The Z-Machine also supports brightness control and can easily toggle backlighting on or off, in both USB and PS2 modes.
