{{main|Wind controller}}
Wind controllers allow MIDI parts to be played with the same kind of expression and articulation that is available to players of wind and brass instruments. They allow breath and pitch glide control that provide a more versatile kind of phrasing, particularly when playing sampled or [[Physical modelling synthesis|physically modeled]] wind instrument parts.<ref name="Huber" />{{rp|95|date=November 2012}} A typical wind controller has a sensor that converts breath pressure to volume information and may allow pitch control through a lip pressure sensor and a pitch-bend wheel. Some models include a configurable key layout that can emulate different instruments' fingering systems.<ref>White, Paul. "[http://www.soundonsound.com/sos/jul98/articles/yamwx5.html Yamaha WX5]".

The EWI uses a system of keypads and rollers modeled after a traditional [[woodwind instrument]], while the EVI is based on an acoustic [[brass instrument]], and has three switches that emulate a [[trumpet]]'s valves.<ref name="Manning">Manning, Peter.

Simpler breath controllers are also available. Unlike wind controllers, they do not trigger notes and are intended for use in conjunction with a keyboard or synthesizer.<ref>{{cite web |title=Breath Controller |url=https://www.sweetwater.com/insync/breath-controller/ |date=Aug 14, 2003 |publisher=Sweetwater |access-date=2020-01-14}}</ref>
