Double deck focus for BCD3000

Hi folks,
Most of 4 deck mappings are limited in layouts of deck controlling. For example kontrol S4 has A-C and B-D switches just like many other controllers (you name it). Point is. What if we want to use decks A and C at the same time, or maybe B and D? I got an idea. We can use deck Focus at one side of controller and what I call it "Hocus Focus" which is created out of modifiers on the other side. So, this way any of 4 decks can be selected and controlled from both sides. This is where shift buttons comes to act. While Shift is hold /FX on/ buttons at effect control section will lite to indicate which deck is selected (every time you press it)) and while holding, move jog wheel at the same side to select any of 4 decks just like Ean's changing FX presets on DJTT S2 mapping video. After selecting deck, when you release Shift BANG /FX on/ button's LED's will jump back where it was before pressing any of both Shifts.
I have already posted this mapping at http://www.traktorbible.com/freaks/m...ew.aspx?id=429 so give it a shot.
