Description

la présente invention concerne, un générateur de composition musicale constitué : de senseurs optiques, d'un contrôleur, d'un ordinateur, éxécutant un programme de composition musicale et de conversion lumière/son, d'un synthétiseur de son, et d'un syn -thétiseur d'images. Permettant une production musicale, par une commande de type "commande par variation de lumière" lues par des senseurs optiques ou une caméra vidéo, au travers d'un con -trôleur pour une production par ordinateur musico-synthétique ou synthèse d'images ou les deux. the present invention relates to a music composition generator comprising: optical sensors, a controller, a computer, executing a music composition and light / sound conversion program, a sound synthesizer, and a image synthesizer. Allowing a musical production, by a type of command "control by variation of light" read by optical sensors or a video camera, through a controller for a production by computer music-synthetic or synthesis of images or the of them.

les inventions précédentes déclanchant une source sonore en obstruant un senseur optique sont limitds, quant au possibilités sonores sur chaque senseurs optiques. De plus les senseurs opti -ques déclenché produisent toujours les mAmes paramètres sonores lors de l'obstruction. Ce procédé.sans l'apport d'un contrôleur et d'un programme d'ordinateur se trouve très peu performant. the previous inventions triggering a sound source by obstructing an optical sensor are limited, as to the sound possibilities on each optical sensor. In addition, the triggered optical sensors always produce the same sound parameters during the obstruction. This process, without the input of a controller and a computer program, is very inefficient.

l'originalité de la commande optique par variation de lumière d'un ordinateur commandant un synthétiseur de son, permet tout types de composition musico-synthétique en temps réel grssce au programme d'ordinateur intervenant au travers du contrôleur sur les sons ou phrases musicales et leurs positionnements lors de ou des variations de lumière intervenues sur les senseurs optique
Ce dispositif, objet de l'invention, est constitué d'un ou de plusieurs panneaux (1) couvert de phototransitors (2) ou d'une caméra vidéo (3). l'élément de base de chacun des panneaux est une carte imprimée en époxy de 0,50m X 0,50m comportant : 64 phototransistors plus une électronique d'amplification par d -ments plus un multiplexage analogique, plus les circuits inter -faces d'entrée numériques plus les circuits interfaces de sortie analogique.D'un contrôleur (4) qui aura les fonctions suivantes séquencer le multiplexage anlogique des panneaux, effectuer la conversion analogique/numérique de la tension obtenue en sortie du multiplexage des panneaux, séquencer la mise en mémoire dans u banc de mémoire locale des valeurs obtenues lors de la conversion les comparer aux valeurs antérieures. Effectuer des cycles de lecture modification écriture, séquencer le dialogue avec l'ordi -nateur de contrôle du synthétiseur optique, gérer l'accès parta -gé à une mémoire locale. the originality of the optical control by variation of light of a computer controlling a sound synthesizer, allows all types of music-synthetic composition in real time thanks to the computer program intervening through the controller on musical sounds or phrases and their positions during or variations in light occurring on the optical sensors
This device, object of the invention, consists of one or more panels (1) covered with phototransitors (2) or a video camera (3). the basic element of each of the panels is a printed epoxy card of 0.50m X 0.50m comprising: 64 phototransistors plus electronics for amplification by elements plus analog multiplexing, plus inter-face circuits digital inputs plus the analog output interface circuits. With a controller (4) which will have the following functions, sequence the analog multiplexing of the panels, perform analog / digital conversion of the voltage obtained at the output of the multiplexing of the panels, sequence the setting memory in a local memory bank of the values obtained during the conversion compare them to the previous values. Carry out read and write read cycles, sequence the dialogue with the optical synthesizer control computer, manage shared access to a local memory.

D'un ordinateur (5) pourvu de ses périphériques de dialogues ( clavier (6) plus visu (7)) et de stockage (unités de disques (8)) qui aura les rôles suivants a explorer la mémoire résidente dans le contrôleur, afin de connaitre l'état des panneaux photo -sensibles. En tirer, grâce au logiciel mis en oeuvre, des con -clusions pour la commande du ou des synthétiseurs. Appliquer les commandes sur le ou les synthétiseurs concernés. D'un synthéti -seur de son, soit numbrique soit analogique (9) commandé par l'ordinateur (5). D'une sonorisation (lu).  A computer (5) provided with its dialogue (keyboard (6) more visible (7)) and storage (disk drives (8)) peripherals which will have the following roles to explore the resident memory in the controller, in order to know the state of the photo-sensitive panels. Using the software implemented, draw conclusions for the control of the synthesizer (s). Apply the commands on the synthesizer (s) concerned. A sound synthesizer, either digital or analog (9) controlled by the computer (5). Sound system (read).

La présente invention, peut être utilisé dans tous les cas ou un élément produit une variation de lumière, sur des senseurs op -tique, pour produire de la musique synthétique par ordinateur ou dé l'image synthétique. Des applications sont intéressantes dans le cadre chorégraphique, un ou plusieurs danseurs évoluant devant les panneaux de senseurs optiques ou la caméra vidéo inter -lriendraient par variation de lumière-sur la production musico -synthétique et pourraient la modifier en fonction de leurs dépla -cements ; dans le cadre musicothérapique ou médical, des handi -capés moteur ayant des problèmes de synchronisme gestuel pourrai -ent avoir un repère dans l'espace ; dans des lieux -publics, centres d'activités urbaines, en fonction du nombre et du type. due déplacement d'un public, celui ci pourrait générer des paysages sonores ; dans le cadre pédagogique, des étudiants en projetant un laser sur les panneaux de photosensibles- ou des diapositives pour -raient avoir plus facilement conscience du rapport entre-l'écri -ture (partition) et sa réalité sonore ; dans le cadre de la vidéo, la caméra peut permettre une production musicale constamment dif -férente suivant les sujets filmés ; dans le cadre du cinéma, un film projeté sur les panneaux de senseurs optiques peut interve -nir sur le programme musico-synthétique et générer de la musique ; placé dans le fond d'un aquarium les poissons par leurs passages pourraient générer une ambiance musicale.  The present invention can be used in all cases where an element produces a variation of light, on optical sensors, to produce synthetic music by computer or of the synthetic image. Applications are interesting in the choreographic framework, one or more dancers evolving in front of the optical sensor panels or the video camera inter -lriendrait by variation of light-on the musico -synthetic production and could modify it according to their displacements; in the context of music therapy or medicine, people with motor disabilities with problems of gestural synchronism could have a reference in space; in public places, urban activity centers, depending on the number and type. due to the displacement of an audience, this could generate soundscapes; in the educational context, students projecting a laser on the photosensitive panels - or slides - could be more easily aware of the relationship between the writing (score) and its sound reality; in the context of video, the camera can allow a constantly different musical production according to the subjects filmed; within the framework of the cinema, a film projected on the panels of optical sensors can intervene on the musico-synthetic program and generate music; placed in the bottom of an aquarium the fish by their passage could generate a musical atmosphere.
