Yes it actually is, Arturia just doesn't want to deal with the headache of tech support on it. It can receive SysEx commands. Someone a few months back demonstrated how to change the button lights. I can confirm that it works too, as I used Max/MSP to change the lights. Thanks for reminding me, I had been meaning to add that to one of my main Max patches.
Do a search for SysEx messages, you'll find it from about 3-4 months ago or so.
