I just finished this DIY MIDI controller - it's built for VDMX but thought ableton folk might be into it too.
it's housing two modified nanokontrols and a qwerty keyboard. The toggle left of center is shift which acts a banks selector for the central buttons.
There's more about the project here: http://zealousy.com/2011/05/archaeopter ... ontroller/
I'm going to be making a run of similar controllers in the coming weeks. If any one wants one feel free to get in touch.
Bob.
