Sixty Works make MIDI based controllers for music production and performance. Rather than compete with large manufacturers who make standard control layouts for as many users as possible, Sixty Works work directly with professional musicians to create individual control devices that are highly adapted to their specific needs. They have two examples of work but only to demonstrate what is possible and show the build quality and attention to detailing.
I highly recommend checking out their website and reading some of the articles, especially this one on showmanship in the ever-changing world of music controllers. If ordering a custom controller is too pricey for you Sixty Works also offer extensive resources that will help you on your way to building your own MIDI device.
