Keith McMillen’s K-Bow is a new sensor bow for stringed instruments.
Combined with a standard violin, bass, cello, or viola the K-Bow allows traditional instrumentalists to access the unlimited sound world that a computer provides, while utilizing the virtuosity built from years of practice.
The K-Bow gathers information about a performance through several sensors including an X Y and Z axis accelerometer, grip sensor, tilt sensor, playing pressure, distance from the instrument and gesture recognition. A suite of software lets a musician control the sound of the instrument, record with herself, or send the information to other standard music software.
