Yamaha WX7

The Yamaha WX7 is a wind controller designed for use with electronic music instruments. It was developed in the late 1980s and has been used by a variety of musicians, including Herbie Hancock, Chick Corea, and Jean-Michel Jarre.

The WX7 works by sensing the air pressure and velocity of the player's breath and translating it into MIDI data. This data can then be used to control a variety of electronic instruments, such as synthesizers, samplers, and drum machines.

The WX7 features a breath sensor, a pitch bend wheel, and a variety of buttons and knobs for controlling various parameters. It also has a built-in expression pedal for controlling volume and other parameters. Additionally, the WX7 can be used to control external MIDI devices, such as sequencers and sound modules.
