Bowing sensor for musical instrument
First Claim
1. 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, andat 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 regardless of whether the musical bow member includes features designed for tracking the musical bow member as it is moved across the 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,wherein the guide is configured to maintain the musical bow member in alignment with the at least one optical flow sensor as it is moved across the surface of the optical flow sensor, wherein the musical bow member is in alignment with the at least one optical flow sensor when the at least one optical flow sensor captures an optical image of a portion of the musical bow member while a disparate portion of the musical bow member is not captured in the optical image.

Abstract
The invention provides a music controller, in the form of a bowing sensor. The music controller includes 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.

16. A music controller, being a bowing sensor for bowed musical stringed instrument emulation, comprising:
-
a musical bow member, a saddle-shaped guide for the musical bow member, and at least one optical flow sensor associated with the saddle-shaped 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 regardless of whether the musical bow member includes features designed for tracking the musical bow member as it is moved across the 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, wherein the saddle-shaped guide is configured to maintain the musical bow member in alignment with the at least one optical flow sensor as it is moved across the surface of the optical flow sensor, wherein the musical bow member is in alignment with the at least one optical flow sensor when the at least one optical flow sensor captures an optical image of a portion of the musical bow member while a disparate portion of the musical bow member is not captured in the optical image. - View Dependent Claims (17, 18, 19, 20)
