Actually, I have been anticipating (although I am not aware of anything) for Muse to do something like incorporating their Receptor into a keyboard and then allowing users to load up their own software.
Or there is also the option of doing it D.I.Y. After all, Linux software is ALL open source, so I could see no reason why a person could not load something like Q-ranger, OR Q-tractor on a Linux equipped laptop for example, add a controller keyboard, and there you have it.. a pseudo Media Station. I know it's not QUITE as simple as that, but definitely do-able.
One Man Band sort of got it okay, but restricted itself to Windows and linked only to Yamaha style types, which are notoriously complicated.
There is no doubt Dom is on the right track. And you and I both know that when a major company sees a good idea, instead of copying they just buy it!!
