Abstract
The electronic musical instrument is constructed such as to detect key-on/key-off performed by physical flexion movements of fingers through a pair of performing gloves 1 and 2 so as to effect generation and erase of musical tones in real timings practically matching with fingering performance. An A/D converter 3 converts signals from bend sensors 10 of the performing gloves 1, 2 into digital flexion data. A controller 4 processes the digital flexion data such as to detect a stop motion of a finger to judge a key-on event according to bending velocity information calculated from the sequentially sampled flexion data, thereby generating musical tones. Further, the controller 4 detects a maximum angle according to the flexion data of the finger restored from the key-on state so as to judge a key-off event according to an off-threshold level correlated to the maximum bend depth to thereby erase musical tones.
