Note: If you have updated to the latest MF3D firmware (30 May 2013) you may need to load the Legacy->Standard firmware for this mapping to work as expected. 
This can be found in the Tools->Alternate Firmware section of the MF Utility

 All buttons have a seperate use depending on the bank used and side button pressed; except for the SHIFT button and PLAY/PAUSE button which are the same on all banks.

Instructions:

1. Download all 4 all-inclusive mappings ( they can work seperately but to get full control you need all 4). I created seperate mappings for each bank to make it easier for anyone to customize values , and easy to find bugs if there any problems.

2.Import the 4 .tsi settings into Traktor.

3.Click Bank A to switch to Hotcue/Loops Control.

The top 8 buttons select and store Hotcues 1-8.

They all work according to deck focus, which is selected by pressing the side buttons 1,2,4, or 5. Button 3 is the SHIFT button which you must hold down to delete hotcues. Button 6 is PLAY/PAUSE which is also controlled by Deck Focus. You can select deck focus on any bank and press play.
