What is wind controler?

A wind controller, also known as a wind synthesizer or breath controller, is a musical instrument that detects the breath of the player through a mouthpiece and converts the information into digital signals. The signals are then sent to a synthesizer module or computer, which produces sound based on the player's breath and fingering. Wind controllers are often used in electronic music genres like jazz, fusion, and ambient music, and can replicate the sounds of acoustic wind instruments like saxophones, flutes, and clarinets. Some wind controllers have additional features like finger buttons, pitch bend wheels, and expression pedals for greater control over the sound.
