Keith McMillen Instruments has announced the official release of the K-Board Pro 4. The K-Board Pro 4 is a four-octave MPE MIDI keyboard controller based on the traditional keyboard layout, but with multiple dimensions of touch sensitivity in each key. K-Board Pro 4 sends attack velocity, release velocity, continuous pressure, horizontal position and vertical position data to offer a wide range of musical expression. It can also send Poly Aftertouch messages for communication with expressive legacy controllers.

“I’m excited that Keith McMillen Instruments are bringing out the K-Board Pro 4, further expanding the next generation of expressive keyboard instruments! It’s a joy to play and their expertise in the field of sensor technology and delivering great musical products makes this instrument a guaranteed winner,” said Jordan Rudess of Dream Theater.

MIDI Polyphonic Expression (MPE) is the newest development in MIDI; a standard specification that allows easy integration of multiple, polyphonic per-key dimensions of expressive control. To capture all of this nuanced gesture, K-Board Pro 4 features KMI’s patented Smart Sensor Technology, developed in conjunction with KMI sister company BeBop Sensors. K-Board Pro 4 is USB powered and MIDI class compliant to ensure both portability and compatibility with MacOS, Windows, iOS, Android, as well as MIDI capable hardware.

The K-Board Pro 4 has an MSRP of $929. For more information visit keithmcmillen.com.
