Reply to Turning off LEDs for Cue in VCI-100 SE

The default in the standard VCI-100 mapping included with Traktor Pro / Scratch Pro has the LED for the two Cue buttons as that green and it turns blue when activated. Is it possible to have it off when inactive and blue when activated? I plan to leave it as the Cue button.

Also, I plan to use the two Key buttons to switch the deck transport controls and EQ between A / B and C / D so they'll basically function as Shift buttons with one set as Modifier #3 and the other Modifier #4. Problem is when I use them to load tracks, it loads to both Decks A and C or B and D at the same time.

My last question is whether it's possible to have it work in a latching fashion as in I press the one on the left deck to get it to switch controls to Deck C but the one on the right is independant and still controls Deck B until I press Key to switch it over to Deck D.
