I'm curious to know how the development team from empeg relates to the current group - is there still a group based in Cambridge? It seems as though some of the development carried over as the company/division/technology was sold - how much carried over? Who is who?

Empeg has more or less stayed put while the tides of change washed over the Americans. Rio's firmware development team for the Karma, Cali/Chiba, Nitrus/Eigen, and S series is the Empeg development team. (There was another firmware development team at Rio Tigard in Oregon, who did the Riot and 600/800, but they're not around any more.)

Every new feature in the car-player v3 technology previews, is there because it was written for Karma and we could build the car-player firmware from the same sources without too much effort.
