What is the WX series?
The WX series are the “professional” Yamaha instruments. They are based on the saxophone, although look somewhat sleeker and more high tech. The basic sensor inputs on the instrument are a breath pressure sensor, a pitch bend (bite) sensor, and the keys. When you blow into the instrument, at a certain pressure threshold a Note On is sent. The velocity of the Note On is based on how fast you attack the note. The instrument plays legato, in that if you key a different note while maintaining breath pressure, the controller sends a Note On for the new note before sending the Note Off of the first note. While a note is on, the breath pressure sensor produces a stream of continuous controller messages. This is typically used to control overall volume and brightness. There’s a set of octave switches on the underside of the instruments, controlled by the left thumb. The octave ranges of the fingerings overlap, so it’s possible to thumb the octave shifts at convenient points. The mouthpieces lo
