Abstract: 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.

Abstract: A movement limiting suited for use with air gathering means that may also generate tones as a result of motion created by the energy of the wind gathered, is disclosed. The wind gathering means may be either flexible, or substantially rigid. The means are usually planar but may also be three dimensional.

Abstract: A system for playing a selected one of multiple audio tracks recorded in synchronized fashion with a motion picture on an optical disk. The optical disk has encoded on it a mixing master music and effects (“M&E”) track, or a switching master M&E track. Individual audio tracks are provided for language-specific versions of the same motion picture, but these tracks have data recorded in them only where there is dialog. In this way, for many a motion picture, all tracks but masters will have data recorded for well less than half of the running time of the motion picture. When a mixing master is used, it is mixed with a language-specific track when the latter has dialog; the mixing master contains no dialog. If a switching master is used, it may contain dialog recorded with the M&E; when a language-specific track has dialog recorded in it, it also contains M&E and the track is played to the exclusion of the switching master.

Abstract: While a normal tone of a designated pitch is being generated in response to key depression or other performance operation on a keyboard or other performance operation device, the tone is controlled in response to manipulation of a pedal or other auxiliary performance operator. Namely, once the auxiliary performance operator is manipulated during generation or sounding of the normal tone, generation of an additional tone related to the normal tone is initiated. In this case, in correspondence with ON/OFF operation of the auxiliary performance operator, a resonant tone is generated, as the additional tone, which is peculiar to the currently-generated normal tone and which is also peculiar to the ON/OFF operation of the auxiliary performance operator. Particularly, if the normal tone is still being generated when the auxiliary performance operator has been returned from the ON state to the OFF state, a returning tone related to the currently-generated normal tone is generated as another additional tone.
