Abstract
The invention provides a music controller, in the form of a bowing sensor. The music controller comprises a musical bow member (4) movable over a guide (2). Associated with the guide (2) is at least one optical flow sensor (6) for monitoring the speed and/or angle of the musical bow member (4) when it is moved longitudinally in contact with the guide, and optionally a pressure sensor (14) for monitoring the pressure of the bow member on the guide. That monitored data, combined with input from a keyboard or ribbon controller (16) enables an attached sound generating device (12) to generate sound that emulates the sound of a real bowed performance or other desired output.

11. A music controller, being a bowing sensor for bowed musical stringed instrument emulation, comprising:
-
a musical bow member, a guide for the musical bow member, and at least one optical flow sensor associated with the guide, the at least one optical flow sensor capturing optical images of the musical bow member as it is moved across a surface of the optical flow sensor, wherein the music controller compares successive captured optical images of the musical bow member to derive control data related to the speed and/or angle of the musical bow member relative to the guide. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29, 30)
