RANE 68 MIDI Mapping LED Traktor Pro 2

Hi, I've been trying to set up a RANE 68 to work with Traktor Pro 2.
Of course once working this should apply to other software too.. Ableton etc.
I have been able to map nearly all buttons and modifiers to what I want..
However I now want to make use of the LEDs available.
I believe I have tried every possible option - but still no luck on getting the LEDs to go ON/OFF like I want... even if you don't own a RANE 68 maybe a look at what I might be doing wrong as any help would be greatly appreciated..

RANE 68 connected via USB
Mac OS X 10.7.2
Traktor Pro 2.1.2

RANE 68 Channel:
Set to MIDI in = 1
Set to MIDI out = 1

RANE 68 Manual. Page 16 gives details of Control Change and MIDI on/off:
RANE 68 Manual

Please Note: There is also a 'Backlight Option' on the 68 and this is switched ON/OFF in system preferences.
ON: LEDs are switched on and light up at a 50% Dim mode. When pressed light up to 100% brightness.
OFF: All LEDs are off. When pressed light up to 100% brightness.

Traktor Pro 2 Device Setup:
I have just set up a New General MIDI in TP2 and I am working with the very Bottom Left Button which can be seen in the RANE Manual pages 15/16 set up as a simple Play ON/OFF.

The Button has the numbers 14/15 written on page 16. for MIDI In Assignments.
The Button has the number 20 written on page 15. for MIDI Out Assignments.

In-Port: SIXTY EIGHT
Out-Port: SIXTY EIGHT
Device Target: Deck A

Assignment Table:
Control-------I/O-------Assignment-------Mode-------Mapped To
Deck Play--------In---------Deck A-----------Toggle------Ch01.Note.G#0
Deck Play-------Out---------Deck A-----------Output------Ch01.Note.G#0

Output LED Options:
Controller Range---------Min---------Max
--------------------------------0-------------1
MIDI Range----------------0------------127

Invert and Blend both unchecked.

The above options I have changed to various combinations.. all with no luck with LED ON/OFF.

If anybody could help in any way I would greatly appreciate it.
Many thanks.
