Guys I have a G4V from Gemini, love that device, handling has not big differences to the flagship controllers, but programming it in Traktor is hell!
Today I managed to assign all 16 pads from that controller to slots and cells of a remix deck, the problems I have are:

1. What is the MIDI out command to get each pad lit seperately from others.
The MIDI in command I used is: MIDI in Slot # Cell # Trigger

2. I could not figure out, how to disable all LED's when changing from one tab to others. For example the 'Hot Cue' tab has few pads with LEDs on, when I switch to 'Auto Loop' tab, all pad's LED's turn off. But when I switch from 'Hot Cue' to 'Sample' the previous lighting LED's still remain on.

3. Another thing is Traktor (2.10) related, could not find a solution to disable pitch and tempo form one shot samples. They always try to match the master track tempo.

Hope you can help me. Here is a photo from what I am talking about:
