AI Technical Summary
Technical Problem
In existing electronic wind instruments, it is difficult for performers to switch between the first and second channels of musical notes by adjusting their exhalation, resulting in inconvenience in pitch switching.
Method used
It adopts a dual-inlet design, and combines indicator values to calculate the components and performance control components. By detecting the exhalation intensity of each inlet, it automatically switches the pitch of the musical tone.
Benefits of technology
It enables convenient switching of musical pitch by adjusting the intensity of exhalation, improving the flexibility of performance and the ease of pitch switching.

Abstract
The present application provides an electronic wind instrument, a pitch switching method, and a computer program product, which can easily switch to a sound based on another pitch only by adjusting the performer's breath to the first blow inlet and the second blow inlet. In the case where the intensity index value (Vr) corresponding to the first breath intensity (V1) based on the wind speed of the breath blown into the upper blow inlet (310) and the second breath intensity (V2) based on the wind speed of the breath blown into the lower blow inlet (311) disposed close to the upper blow inlet (310) is a first pitch change threshold (Tcrd) or more, the sound based on another pitch one octave higher than the key pitch according to the interval ratio is started. Thus, the sound based on another pitch can be easily switched by adjusting the wind speed of the breath blown by the performer into the upper blow inlet and the lower blow inlet, like a real pipe instrument such as a flute.
