Description

La présente invention concerne un dispositif électronique à commande mémorisée permettant la reproduction d'une partition de musique sur écran.The present invention relates to an electronic device with memorized control allowing the reproduction of a music score on a screen.

Souvent, les ensembles de musiciens jouent en s'aidant de partitions en mauvais état, voire même délabrées car les partitions coûtent cher et ne sont pas rééditées régulièrement. De plus, à chaque fin de page, plusieurs musiciens d'un même ensemble sont obligés d'interrompre leur jeu pour tourner la page de la partition.Often, groups of musicians play with the help of scores in poor condition, or even dilapidated because the scores are expensive and are not re-released regularly. In addition, at each end of the page, several musicians from the same ensemble are forced to interrupt their play to turn the page of the score.

Le brevet BE-A 901 563 décrit un pupitre d'orchestre avec un écran de TV de couleur comprenant des moyens pour faire tourner automatiquement les pages à l'aide d'un compteur de notes. Il ne ressort toutefois pas de ce document comment s'effectuent le comptage des notes et l'asservissement.Patent BE-A 901 563 describes an orchestral desk with a color TV screen comprising means for automatically turning the pages using a note counter. However, this document does not show how the counting of scores and enslavement are carried out.

L'invention a pour objet un dispositif qui permet à tout musicien d'un ensemble de disposer d'une partition impeccable et claire et qui permet d'éviter au musicien des manipulations de partition malaisées.The subject of the invention is a device which allows any musician in an ensemble to have an impeccable and clear score and which makes it possible to avoid awkward score manipulation for the musician.

  • a control panel;
  • a housing for receiving and placing a partition support, said support carrying information representing the musical score and positioning indicators at predetermined positions;
    means for reading and displaying on the screen the partition information carried by said support: a drive device for advancing the partition support so as to display on the screen successive parts of the partition; and a control system organized to monitor the execution of the musical composition and to automatically control said training device at the rate of the execution of the musical composition, characterized in that predetermined musical measures of each score page are stored for reference and in that the servo system comprises a microphone for picking up the sounds emitted during the execution of the musical composition and producing electrical signals corresponding to the successive musical frequencies and means for producing a control signal to activate the drive device each time the signals received correspond to the signals memorized in the form of marks.

Dans un mode de réalisation exemplaire, le dispositif de commande électronique comprend un microphone pour capter les sons émis pendant l'éxecution de la composition musicale et produire des signaux électriques représentant les fréquences musicales successives, un convertisseur analogique/numérique pour convertir les signaux produits par le microphone en une suite de signaux binaires, une mémoire organisée pour contenir des signaux numériques de référence représentant des suites de mesures musicales prédéterminées servant de références, un dispositif de reconnaissance de mesures musicales connecté pour recevoir les signaux binaires du convertisseur et les signaux de référence de la mémoire et pour produire un signal de commande de changement de page chaque fois qu'une séquence typique de signaux binaires est identique à un signal de référence, ce signal de commande de changement de page servant à actionner le dispositif d'entraînement du support de partition afin de faire avancer le support de partition de manière à afficher sur l'écran une partie suivante de la partition.In an exemplary embodiment, the electronic control device comprises a microphone for picking up the sounds emitted during the execution of the musical composition and producing electrical signals representing the successive musical frequencies, an analog / digital converter for converting the signals produced by the microphone in a series of binary signals, a memory organized to contain digital reference signals representing sequences of predetermined musical measures serving as references, a device for recognizing musical measures connected to receive the binary signals from the converter and the reference signals memory and to produce a page change command signal whenever a typical sequence of binary signals is identical to a reference signal, this page change control signal used to actuate the media drive partition in order to advance the su partition pport so as to display on the screen a next part of the partition.

Le dispositif selon l'invention présente l'avantage d'offrir à chaque exécutant d'un ensemble musical des partitions claires et impeccables, et d'assurer que pour tous les exécutants, les partitions défilent en synchronisme. Les manipulations malaisées des partitions sont ainsi éliminées.

Uneasy manipulation of partitions is thus eliminated. In addition, the device allows the conductor to intervene more efficiently, more precisely and more quickly.

L'invention est exposée dans ce qui suit en s'appuyant sur les dessins ci-annexés dans lesquels :

  • la figure 1 est une vue en perspective d'une console pouvant constituer un pupitre de musique télévisuel conforme à l'invention,
  • la figure 2 illustre schématiquement un mode de réalisation exemplaire du dispositif selon l'invention,
  • la figure 3 est un schéma simplifié exemplaire du dispositif de commande électronique logé dans la console.
The invention is set out in the following based on the attached drawings in which:
  • FIG. 1 is a perspective view of a console which can constitute a television music stand according to the invention,
  • FIG. 2 schematically illustrates an exemplary embodiment of the device according to the invention,
  • FIG. 3 is a simplified exemplary diagram of the electronic control device housed in the console.

Se reportant à la figure 1, on montre une vue d'un modèle de console constituant un pupitre de musique télévisuel selon l'invention. La console 1 présente sur sa face frontale un écran de visualisation 2 destiné à afficher ou visualiser une partie d'une partition de musique 20 et un tableau de commande 3 permettant à l'usager d'effectuer diverses commandes comme on le verra plus loin. Dans l'exemple de réalisation illustré, l'écran 2 est prévu pour afficher simultanément deux pages successives d'une partition.Referring to Figure 1, there is shown a view of a console model constituting a television music stand according to the invention. The console 1 has on its front face a display screen 2 intended to display or display part of a musical score 20 and a control panel 3 allowing the user to carry out various commands as will be seen below. In the illustrated exemplary embodiment, the screen 2 is provided for simultaneously displaying two successive pages of a score.

La partition est enregistrée sur un support quelconque : par exemple un microfilm logé dans une cassette ou porté par un disque visuel, ou encore une disquette, un disque à lecture magnétique, un disque video, etc. Le support de partition est associé de manière opérationnelle à un dispositif pour lire la partition enregistrée et l'afficher sur l'écran 2. Le dispositif pour lire et afficher la partition est évidemment adapté au type de support portant la partition enregistrée.The score is recorded on any medium: for example a microfilm housed in a cassette or carried by a visual disc, or even a floppy disk, a magnetic reading disc, a video disc, etc. The partition support is operatively associated with a device for reading the recorded partition and displaying it on the screen 2. The device for reading and displaying the partition is obviously adapted to the type of support carrying the recorded partition.

La figure 2 représente schématiquement un mode de réalisation exemplaire simple. La console 1 est montée sur un socle 15 de manière à pouvoir être inclinée au gré de l'usager par basculement autour d'un pivot 16. Il va de soi que la console peut être montée d'autre manière, y compris de façon fixe.FIG. 2 schematically represents a simple exemplary embodiment. The console 1 is mounted on a base 15 so that it can be tilted at the option of the user by tilting around a pivot 16. It goes without saying that the console can be mounted in other ways, including fixedly .

Dans cet exemple, le support de partition 4 est un microfilm logé dans un compartiment 5 de la console 1, par exemple un tiroir, pour être mis en coopération fonctionnelle avec un dispositif optique agencé pour qu'une partie de la partition enregistrée sur le support 4 puisse être affichée par projection sur l'écran 2. Le dispositif optique comprend une source lumineuse 6, un miroir 7, par exemple un miroir semi-transparent, et un objectif 8. Une source lumineuse de secours 6' est avantageusement prévue également. Lorsque le support de partition 4 est mis en place, il se trouve sur le trajet du faisceau lumineux émis par la source 6 et réfléchi par le miroir 7 et les informations visuelles portées par le support de partition 4, dans la partie qui intercepte le faisceau lumineux, se trouvent projetées par l'objectif 8 sur l'écran 2. Un dispositif d'entraînement 9 est prévu pour faire avancer le support de partition 4 en réponse à un signal d'avancement de manière à remplacer au moment voulu la page de partition affichée sur l'écran 2 par la page suivante. Le signal d'avancement du support de partition est engendré par un dispositif de commande électronique incorporé qui sera décrit plus loin. L'avancement du support de partition se fait ainsi page par page, le pas d'avancement étant défini par des indicateurs de positionnement prévus sur le support de partition.In this example, the partition support 4 is a microfilm housed in a compartment 5 of the console 1, for example a drawer, to be put into functional cooperation with an optical device arranged so that part of the partition recorded on the support 4 can be displayed by projection on the screen 2. The optical device comprises a light source 6, a mirror 7, for example a mirror semi-transparent, and a lens 8. An emergency light source 6 ′ is advantageously also provided. When the partition support 4 is put in place, it is on the path of the light beam emitted by the source 6 and reflected by the mirror 7 and the visual information carried by the partition support 4, in the part which intercepts the beam illuminated, are projected by the objective 8 on the screen 2. A driving device 9 is provided for advancing the partition support 4 in response to a progress signal so as to replace the page of time at the desired time. partition displayed on screen 2 by the following page. The progress signal of the partition support is generated by an incorporated electronic control device which will be described later. The advancement of the partition support is thus done page by page, the step of advancement being defined by positioning indicators provided on the partition support.

Sur chaque page de patition est choisie une suite de mesures musicales caractéristiques pour servir de repère sur cette page afin de commander le changement de page, et chaque suite repère est représentée et identifiée par une suite de signaux binaires de référence RC stockée en mémoire. Dans un mode de réalisation exemplaire avantageux, les signaux de référence RC sont enregistrés dans des emplacements prévus sur le support de partition lui- même et répartis sur une piste mémoire courant le long de l'enregistrement de la partition. Dans un autre mode de réalisation, les signaux de référence RC pourraient être stockés dans une mémoire séparée dont l'avancement serait lié à l'avancement du support de partition. Les signaux de référence RC sont utilisés dans le dispositif de commande électronique qui est décrit ci-après en se reportant à la figure 3.On each patition page is chosen a series of characteristic musical measures to serve as a reference on this page in order to control the change of page, and each reference sequence is represented and identified by a series of binary reference RC signals stored in memory. In an advantageous exemplary embodiment, the reference signals RC are recorded in locations provided on the partition support itself and distributed on a memory track running along the recording of the partition. In another embodiment, the reference signals RC could be stored in a separate memory whose progress would be linked to the progress of the partition support. The RC reference signals are used in the electronic control device which is described below with reference to FIG. 3.

Un microphone 21 monté sur la console 1 capte les sons musicaux produits pendant l'exécution d'une oeuvre musicale. Ce microphone engendre des signaux électriques FS correspondant aux fréquences musicales successives et ces signaux analogiques sont reçus dans un convertisseur analogique/numérique 23 qui convertit chaque signal FS en un code de signaux binaires BC. Les signaux binaires constituant les codes BC successifs sont reçus dans un dispositif de reconnaissance de séquence 24 pour être comparés avec les signaux de référence RC mémorisés. Les signaux de référence RC sont lus sélectivement dans la mémoire 26 par un dispositif de lecture ou scrutateur 25 (la mémoire 26 représente la piste mémoire précitée ou une zone mémoire quelconque séparée). Le dispositif de lecture peut être constitué d'un dispositif quelconque propre à lire des signaux binaires. Dans la figure 3 le dispositif de reconnaissance de séquence est représenté symboliquement par une porte-ET qui conventionnellement représente la fonction logique globale du dispositif. Cependant, il est bien évident pour l'homme de l'art que le dispositif 24 peut être réalisé sous la forme de divers montages utilisant des éléments logiques connus en soi, agencés pour réaliser la fonction logique requise telle que décrite ici. Le nombre d'éléments dans ces montages peut dépendre du nombre de mesures musicales formant une suite-repère. L'organisation de tels montages logiques relève de la compétence de l'homme de métier.A microphone 21 mounted on the console 1 picks up the musical sounds produced during the performance of a musical work. This microphone generates electrical signals FS corresponding to the successive musical frequencies and these analog signals are received in an analog / digital converter 23 which converts each signal FS into a binary signal code BC. The binary signals constituting the successive BC codes are received in a sequence recognition device 24 to be compared with the stored RC reference signals. The RC reference signals are selectively read from the memory 26 by a reading device or scanner 25 (the memory 26 represents the aforementioned memory track or any separate memory area). The reading device can consist of any device suitable for reading binary signals. In FIG. 3, the sequence recognition device is symbolically represented by an AND gate which conventionally represents the overall logical function of the device. However, it is obvious to a person skilled in the art that the device 24 can be produced in the form of various arrangements using logic elements known per se, arranged to perform the required logic function as described here. The number of elements in these montages can depend on the number of musical measures forming a benchmark suite. The organization of such logical arrangements falls within the competence of the skilled person.

A chaque position du support de partition 4, le lecteur 25 lit le code de référence RC et l'applique à l'entrée 200 du dispositif de reconnaissance 24. Lorsque celui-ci reçoit du convertisseur 23 une suite de signaux BC identique au code de référence RC, il produit un signal de commande PS pour actionner le dispositif d'entraînement 9 du support de partition de manière à faire avancer le support 4 pour afficher sur l'écran 2 la page de partition suivante. Le lecteur 25 lit alors le code de référence RC porté sur la page suivante pour l'appliquer à l'entrée 200 du dispositif de reconnaissance 24 et lorsque celui-ci reçoit à son entrée 100 un signal binaire BC qui est identique au code de référence RC lu par le lecteur, il produit un nouveau signal de commande PS pour faire de nouveau avancer le support de partition d'une page. Ainsi, à mesure que l'exécution d'un morceau de musique progresse, la partition affichée se trouve-t-elle décalée automatiquement page par page.At each position of the partition support 4, the reader 25 reads the reference code RC and applies it to the input 200 of the recognition device 24. When the latter receives from the converter 23 a series of signals BC identical to the code of reference RC, it produces a control signal PS to actuate the drive device 9 of the partition support so as to advance the support 4 to display on screen 2 the following partition page. The reader 25 then reads the reference code RC carried on the next page to apply it to the input 200 of the recognition device 24 and when the latter receives at its input 100 a binary signal BC which is identical to the reference code RC read by the reader, it produces a new PS control signal to again advance the partition support of a page. Thus, as the performance of a piece of music progresses, the displayed score is automatically shifted page by page.

Dans le cas où la mémoire n'est pas aménagée sur le support de partition, on peut prévoir que le signal de commande PS qui fait avancer le support de partition d'une page fait en même temps avancer la mémoire d'une position de manière que le dispositif de lecture lise le code de référence RC suivant, c'est-à-dire le code correspondant à la suite-repère choisie sur la page de partition suivante.In the case where the memory is not arranged on the partition support, it can be provided that the control signal PS which advances the partition support by one page at the same time advances the memory by one position so that the reading device reads the following reference code RC, that is to say the code corresponding to the reference sequence chosen on the next partition page.

Une temporisation prédéterminée peut être prévue dans la commande de l'avancement du support de partition 4 selon le nombre de mesures qui séparent la suite de mesures musicales servant de repère de la dernière mesure musicale figurant sur la page de partition. Chaque fois qu'une suite-repère se trouve ainsi reconnue au cours de l'exécution d'une oeuvre musicale, la partition affichée sur l'écran change, progressant de page en page.A predetermined time delay can be provided in the control of the advancement of the score medium 4 according to the number of measures which separate the series of musical measures serving as a reference for the last musical measure appearing on the score page. Each time a benchmark sequence is thus recognized during the performance of a musical work, the score displayed on the screen changes, progressing from page to page.

Dans le cas où l'écran 2 est prévu pour présenter simultanément deux pages consécutives de la partition comme montré à la figure 2, par exemple, l'écran affiche au cours d'une exécution d'une composition musicale successivement les pages 1-2, puis les pages 2-3, ensuite les pages 3-4, et ainsi de suite.In the case where screen 2 is provided for simultaneously presenting two consecutive pages of the score as shown in FIG. 2, for example, the screen displays pages 1-2 during a musical composition execution , then pages 2-3, then pages 3-4, and so on.

Grâce à la disposition selon l'invention, chaque exécutant d'un ensemble musical peut toujours disposer de partitions claires et impeccables et n'est plus astreint à des manipulations malaisées de partition pendant l'exécution d'une oeuvre musicale. De plus, les partitions défilent en synchronisme pour tous les exécutants, aidant ainsi à l'harmonie de l'ensemble.Thanks to the arrangement according to the invention, each performer of a musical ensemble can always have clear and impeccable partitions and is no longer forced to awkward manipulations of partition during the performance of a musical work. In addition, the scores parade in synchronism for all the performers, thus helping the harmony of the whole.

L'avancement automatique par pas du support de partition sous la direction du dispositif de commande peut être arrêté à l'initiative de l'usager. Pour ce faire, celui-ci se sert du tableau de comande 3. Une vue d'ensemble d'un mode de réalisation exemplaire est montrée à la figure 1 dans laquelle les liaisons entre le tableau de commande et le dispositif électronique 22 ne sont pas représentées pour ne pas surcharger le dessin. Le tableau de commande est conçu, entre autres choses, pour permettre à l'usager de choisir une page voulue quelconque de la partition ou pour changer de page après avoir mis le dispositif en mode manuel, c'est-à-dire après avoir inhibé ou rendu inopérant le système de commande automatique.The automatic advance by step of the partition support under the direction of the control device can be stopped at the initiative of the user. To do this, it uses the control panel 3. An overview of an exemplary embodiment is shown in Figure 1 in which the connections between the control panel and the electronic device 22 are not represented so as not to overload the drawing. The control panel is designed, among other things, to allow the user to choose any desired page of the partition or to change the page after having put the device in manual mode, that is to say after having inhibited or made inoperative the automatic control system.

Dans l'exemple montré à la figure 1, on distingue un commutateur 31 pour inhiber le dispositif électronique et mettre le dispositif en mode de fonctionnement manuel. Le numéro de la page à visualiser sur l'écran est choisi en formant sur le clavier 32 le numéro correspondant à la page voulue, ce numéro étant affiché sur un témoin 34. Deux touches 36A et 36B permettent de rétrograder ou d'avancer d'une page respectivement. Cette faculté est évidemment utile au cours des répétitions.In the example shown in FIG. 1, there is a switch 31 for inhibiting the electronic device and putting the device in manual operating mode. The number of the page to be displayed on the screen is chosen by forming on the keyboard 32 the number corresponding to the desired page, this number being displayed on an indicator 34. Two keys 36A and 36B allow to downgrade or to advance one page respectively. This ability is obviously useful during rehearsals.

Le tableau de commande de la figure 1 est également prévu pour permettre à l'usager, après avoir mis le dispositif en mode manuel, d'ajuster le rythme d'exécution voulu d'un mouvement musical. L'usager se sert alors du clavier 33 pour former un nombre indiquant le nombre de temps par minute, ce nombre étant affiché sur le témoin 35. Les touches 37A et 37B permettent respectivement de ralentir ou d'accélérer le rythme d'un temps à la fois.The control panel of FIG. 1 is also provided to allow the user, after having put the device in manual mode, to adjust the desired rhythm of execution of a musical movement. The user then uses the keyboard 33 to form a number indicating the number of times per minute, this number being displayed on the indicator 35. The keys 37A and 37B respectively make it possible to slow down or accelerate the rhythm from time to time. that time.

Le rythme ainsi choisi est visualisé par un témoin clignotant 38, commandé par exemple par un générateur de temps dont la fréquence est ajustée par la combinaison de signaux produite par les touches du clavier 33 qui ont été actionnées par l'usager. En actionnant à nouveau le commutateur 31, l'opérateur peut remettre le dispositif en fonctionnement automatique, rendant ainsi de nouveau le système électronique opérationnel, le témoin clignotant 38 indiquant le nouveau rythme choisi. Les répétitions sont ainsi facilitées tout en permettant au chef d'orchestre d'intervenir de façon plus efficace et plus précise.The rhythm thus chosen is displayed by a flashing indicator 38, controlled for example by a time generator whose frequency is adjusted by the combination of signals produced by the keys of the keyboard 33 which have been actuated by the user. By actuating the switch 31 again, the operator can return the device to automatic operation, thus again making the electronic system operational, the flashing indicator 38 indicating the new rhythm chosen. Rehearsals are thus facilitated while allowing the conductor to intervene more effectively and more precisely.

Un commutateur 39 est évidemment prévu également pour mettre le dispositif en service ou hors service (commutateur marche/arrêt). Lorsque ce commutateur se trouve placé en position arrêt, il est prévu que le dispositif d'entraînement du support de partition remette celui-ci automatiquement dans la position initiale, prêt pour permettre une nouvelle exécution de la partition, après quoi le dispositif est mis hors tension.A switch 39 is obviously also provided to put the device on or off (on / off switch). When this switch is placed in the off position, it is expected that the partition support drive automatically returns it to the initial position, ready to allow a new execution of the partition, after which the device is deactivated. voltage.

Il va de soi que l'agencement des moyens prévus pour lire et afficher la partition sur l'écran de visualisation peut être différent de l'agencement illustré et qu'il sera adapté de façon appropriée au type de support de partition adopté. Comme dit plus haut, le support de partition n'est nullement limité au microfilm ou au disque visuel; il pourrait être constitué d'un disque à lecture magnétique ou d'un disque vidéo, par exemple. Dans ce cas, le dispositif pour lire et afficher la partition, ainsi qu'il est bien connu de l'homme de l'art, comprendra un moyen de lecture pour lire les informations enregistrées sur le support de partition, et des moyens pour convertir les informations lues sur ledit support en signaux propres à commander l'affichage de la partition sur l'écran de visualisation.It goes without saying that the arrangement of the means provided for reading and displaying the partition on the display screen may be different from the arrangement illustrated and that it will be appropriately adapted to the type of partition support adopted. As said above, the partition medium is by no means limited to microfilm or visual disc; it could consist of a magnetic disc or a video disc, for example. In this case, the device for reading and displaying the partition, as is well known to those skilled in the art, will include reading means for reading the information recorded on the partition medium, and means for converting the information read from said support into signals suitable for controlling the display of the partition on the display screen.
