Behringer have added full-sized MIDI controller keyboards to their ever expanding range. Here at the NAMM 2014 show, we saw the new Motor 61 and Motor 49 models. With 9 motorized faders as well as 8 pressure and velocity sensitive backlit pads each with four switchable banks you get a considerable number of controls. I was also pleased to see that the keyboard features aftertouch.
I'm pretty sure that this is the first MIDI controller keyboard with moving faders, at least nine of them, though you do need to be powered from an external PSU to get them moving, working bus powered will not provide enough juice.
Available in Spring Summer this year, the MOTOR series are pretty agressively priced at around $449 Motor 61 and $349 for the Motor 49
