<p>A breath detection signal from a breath sensor section (1) is converted to a digital breath detection signal, and when the value of the detection signal exceeds a preset value, a tone is generated. After the tone generation, a tone parameter of the tone being generated is controlled according to the value of said digital breath detection signal. When a predetermined period of time is elapsed from an instant when the digital breath detection signal exceeds a preset signal, initial breath data is generated in correspondence to the breath detection signal or preset value at that instant. The tone parameter of the tone at the time of the tone generation is controlled according to initial breath data. After the generation of the tone, the tone parameter of the tone being sounded is controlled according to after-breath data corresponding to the breath detection signal. The pitch determination of the tone to be generated is performed by a pitch designation operation section (5) provided on a musical instrument body having a mouthpiece input section.</p> |
