A wind controller is disclosed which provides glitch-free playing of the instrument by using key position sensors which produce tristate logic signals indicating released, held, or transition positions of each key. Logic circuitry processes the key position signals and prevents any note from sounding when any of the keys is in transition between the released and held positions. The controller also allows the player to select alternate fingering charts which avoid "mine field" fingerings and which are created and downloaded to the wind controller using a personal computer. A set of chord keys and a computer program allows the player to register, without sounding, a series of notes to make up a chord using a registration key and an enable/disable key which alternately activates the last registered chord for playing or deactivates it to return to monophonic mode. Another registration key is provided to register another chord whereby an endless progression of chords can be played in succession.
