Pearl and Keith McMillen Instruments have announced their entry into the MPE (Midi Polyphonic Expression) keyboard controller market with the K-Board Pro 4. The K-Board Pro 4 is a four-octave Midi keyboard controller based on the traditional look of a piano with multiple levels of touch sensitivity in each key. It sends attach velocity, release velocity, continuous pressure, horizontal position and vertical position data to offer the deepest level of musical expression. This unique function is achieved by sending control messages to multiple midi channels, allowing the commands to be transmitted separately rather than the conventional method where the controls function globally and the effects are unison. K-Board Pro 4 features KMI's patented Smart Sensor Technology that is the core of all the KMI control surfaces. K-Board Pro 4 is USB powered and class compliant to ensure both portability and compatibility with MacOS, Windows iOS, Android as well as MIDI capable hardware.
