Welcome Nils. I can't help you with the newface, but I'll try to help a bit with the button query. If you follow the Eutronix link at the top of the page, it will take you to a place where they offer the kit and/or service to install the LED's necessary to have lit buttons. There is noone producing buttons at present, as Brian, the guy that used to do them (and is linked at the top of the page) seems to have stopped producing them. Firefox31 has been working for several months with casters and prototypers to get more produced. There should be some availible within the next few months for purchase. Watch the Announcements board and the Projects board for further developments. I believe this thread has the latest progress update.
