Title: Musical sound controller
Inventor: MATSUBARA AKINORI
IPC: G10H1/34
Filed: 1996-01-24
Abstract: PROBLEM TO BE SOLVED: To provide a controller which is of simple constitution and can control a musical sound without causing unintended characteristic change by providing a specific output variable means, a specific detecting means, and a specific control means. SOLUTION: The output variable means (optical sensor 12) changes its output with the distance to a body, e.g. a hand and the detecting means (CPU 13) detects the variation speed of the output. When the detected variation speed is less than a specific value, a control means (CPU 13) controls characteristics of a musical sound according to the output of the optical sensor 12. Therefore, characteristics of a musical sound signal can be varied by putting the hand close to or away from the optical sensor 12 at such a speed that the variation speed is less than the specific value. Further, when the hand is moved abruptly from the optical sensor 12 along the strings, the variation speed of the output of the optical sensor 12 becomes larger than the specific value.  In this case, the CPU 13 ends the control over the musical sound signal corresponding to the output of the optical sensor 12 in response.
