Today, innovative hardware company Keith McMillen has announced that, after a successful Kickstarter, their newest K-Board 4 has begun shipping. Touted as the ultimate MPE keyboard, the programmable hardware builds off the company's success as a leader of innovative technology. For those who are unfamiliar with MPE, it's short for MIDI Polyphonic Expression, and is essentially the next evolution of MIDI, allowing you to do connect with your hardware and software on a deeper level by sending multiple signals from one source. This is the same technology found in products from Roli, Roger Lynn, and more, for those are familiar. You can find out more information about MPE here.
