I did some research myself as well and the situation seems preety bad. All the relevant hardware doesn't even mention mmc. Everything seems be done through drivers, customized and tweaked for the major sequencer/DAW suites. There seems to be no standard at all. On some manufacturers forums, there is a handful or requests from linux users (for specifications and support), none taken seriously. So yes, us428 seems to be the only choise. Or perhaps some alternatives... like having another keyboard and mapping some shortcuts. :)
