What is wind instrument with a keyboard?

A wind instrument with a keyboard is known as a wind controller or a wind synthesizer. It is essentially a synthesizer that uses a breath controller or a wind sensor to emulate the sounds of traditional wind instruments like a flute, saxophone, or a trumpet. The keyboard of a wind controller functions like a regular keyboard and allows the player to produce the required notes.

The wind sensor on the instrument measures the breath pressure and converts it into a MIDI signal that controls the sound produced by the synth. The player can shape the sound by using breath pressure, pitch control, and modulation. The wind controller provides a realistic experience of playing a wind instrument as it produces a sound that reacts to the nuances of the player's breath control.

The wind controller is commonly used in music genres like jazz, fusion, and electronic music. It provides a versatile option for musicians to experiment with new sounds and textures. Some popular manufacturers of wind controllers include Akai, Yamaha, and Roland.
