I can't answer your question about software etc, but normally leds that have the ability to change colours do so via a slight controlled voltage variance, in addition it may depend also how they have been wired - in series I think sends the light colour change staggered.
I think people will be ABSOLUTELY BLOWN AWAY when they see the LEDS on the Premium and LE models. 
I am definately going to do my Pro, but the question I have, is there additional code with the Premium/LE models that makes all the colour changing LEDS work in unison (together at the same time). IF this question can be answered by looking at the machine/contacting STERN, It might help PRO owners determine how best to tackle the LEDS on the ac/dc PRO model. I am thinking there might be, for all 30 Leds to all change colours at the same time, and the exact same colour. ? because, to my mind, wouldnt all the LEDs just change colours randomly if there wasnt something controlling it ? I know LEDS, but not to this extent !
*Dying to see the LEDS in the higher models. Should be very special. I think Petes going to have a blast, followed by 20 questions from me and a few dozen requests for videos of the new toy !
p.s - Steve Ritchie, what a top bloke. That video/documentary of the making of AC?DC is a excellent video. I must have watched it 20 times now. It doesnt get old at all.
