Abstract

Through a simplified keyboard (2) and by means of a set of displays and indicators, the user enters into the memory (64) of the present musical sequencer the data composing the melodies in several parts which he can then listen to on the internal loudspeaker (53) by isolating the voice part(s) of his choice, by modifying the tempo or by selecting the extract he wishes to hear. A microprocessor (61) and a suitable software (63) control the keyboard as well as the indicators and the displays associated with the various functions of the apparatus by means of the interface (62). They also control the frequency values and the lengths of the sounds produced by the programmable oscillators (64). An audio device enables by means of the audio outpout (58) melodies to be saved by encoding them in a cassette recorder. The apparatus is equipped with a headset output (59) and a MIDI output (56).

Description

PETIT APPAREIL ELECTRONIQUE PROGRAMMABLE AUTONOME POUR L'ENSEIGNEMENT ET L'ETUDE DU SOLFEGESMALL AUTONOMOUS PROGRAMMABLE ELECTRONIC DEVICE FOR THE TEACHING AND STUDY OF SOLFEGE
Le but de la présente invention est de restituer sur un petit haut-parleur (53) incorporé dans un coffret standard (1) , des mélodies à plusieurs voix, intro¬ duites dans une mémoire non volatile (64) directement par l'utilisateur au moyen d'un clavier comportant un nombre réduit de touches (33 à 48), accompagnées de voyants (10 à 32) et d'une sérigraphie explicite (69), comportant tous les symboles usuels du solfège.The object of the present invention is to restore on a small loudspeaker (53) incorporated in a standard cabinet (1), melodies with several voices, introduced into a non-volatile memory (64) directly by the user at the means of a keyboard comprising a reduced number of keys (33 to 48), accompanied by lights (10 to 32) and an explicit serigraphy (69), comprising all the usual symbols of music theory.
Dans l'état actuel de la technique il n'existe que des appareils de 'haut de gamme' permettant d'obtenir d^s performances voisines. Ces appareils portent le nom de 'séquenceurs' , mais contrairement à la présente inven¬ tion ils ne présentent aucun but didactique. Ils sont plutôt destinés à réaliser des 'maquettes musicales' ou des enregistrements d'accco pagnement pour chan¬ teurs. De plus ils nécessitent généralement- pour la saisie des informations un clavier type orgue électro¬ nique, et pour la restitution un synthétiseur et un amplificateur. L'ensemble de ces appareils représente donc un coût élevé qui le destine à des utilisateurs avertis.In the current state of the art, there are only 'top-of-the-range' devices making it possible to obtain similar performances. These devices bear the name of 'sequencers', but contrary to the present invention they have no didactic purpose. They are rather intended to make 'musical models' or accompaniment recordings for singers. In addition, they generally require a keyboard of the electronic organ type to input information, and a synthesizer and an amplifier for playback. All of these devices therefore represent a high cost which is intended for informed users.
Le procédé selon la présente invention s'en distingue très nettement par son extrême simplification, son coût réduit et son application technique toute diffé¬ rente en ce sens qu'elle est orientée vers un but didactique. Il s'agit là, non plus de produire des sons musicaux pour l'agrément de l'oreille, mais de faciliter l'apprentissage du solfège par l'écoute répétée des exercices de solfège ou mélodies introdui- tes dans l'appareil par l'utilisateur lui-même à partir des partitions de son choix.The method according to the present invention differs very clearly therefrom by its extreme simplification, its reduced cost and its completely different technical application in the sense that it is oriented towards a didactic goal. It is no longer a question of producing musical sounds for the pleasure of the ear, but of facilitating the learning of music theory by repeated listening to music theory exercises or melodies introduced. tes in the device by the user himself from the partitions of his choice.
Les sons délivrés par l'appareil sont générés par des oscillateurs programmables du type 68B40 (65) . Ces oscillateurs permettent d'obtenir la fréquence des sons à produire. Les signaux de sortie de ces oscil¬ lateurs sont ensuite mélangés à l'aide des composants (résistances et condensateurs) associés à un circuit de mixage (67) .The sounds delivered by the device are generated by programmable oscillators of the 68B40 (65) type. These oscillators make it possible to obtain the frequency of the sounds to be produced. The output signals of these oscillators are then mixed using components (resistors and capacitors) associated with a mixing circuit (67).
Chacune des sorties des oscillateurs est associée à une voix de l'appareil. Etant donné qu'il est possible d'invalider isolément les sorties des oscillateurs, ceci permet d'écouter une voix unique ou toute combi- naison des voix jusqu'à concurence du nombre maximum des sorties des oscillateurs utilisés.Each of the oscillator outputs is associated with a voice of the device. Since it is possible to disable the oscillator outputs individually, this allows you to listen to a single voice or any combination of voices up to the maximum number of oscillator outputs used.
Un signal supplémentaire est également mélangé aux précédents, généré par une des sorties d'un buffer de type 'latche' contenu dans l'interface (62), signal produisant un top" sonore destiné à simuler les batte¬ ments d'un métronome.An additional signal is also mixed with the previous ones, generated by one of the outputs of a buffer of the 'latche' type contained in the interface (62), signal producing a sound “top ” intended to simulate the beats of a metronome.
L'ensemble de ces signaux est alors envoyé à l'entrée d'un circuit amplificateur (68) permettant, avec l'ai- de d'un potentiomètre (57), situé sur la face arrière du coffret, de régler un niveau d'écoute correct. Une prise DIN 180e (58) permet le raccordement sur un amplificateur externe. Une prise du type JACK (59) permet le branchement d'un petit casque du type balladeur, ce branchement coupant automatiquement l'écoute sur le haut-parleur interne. Ces deux derniè¬ res prises sont également situées sur la face arrière du coffret. Un troisième connecteur (55) se trouve également situé à l'arrière du coffret. Il est destiné au raccordement de l'alimentation 9 Volts externe à l'appareil. CetteAll of these signals are then sent to the input of an amplifier circuit (68) making it possible, with the help of a potentiometer (57), located on the rear face of the cabinet, to adjust a level of correct listening. A DIN 180 e socket (58) allows connection to an external amplifier. A jack of the JACK type (59) allows the connection of a small headset of the walkman type, this connection automatically cutting off the listening on the internal loudspeaker. These last two sockets are also located on the rear face of the cabinet. A third connector (55) is also located at the rear of the cabinet. It is intended for connecting the 9 Volt external power supply to the device. This

Les voyants lumineux (10 à 32) ainsi que les chiffres lumineux, dits afficheurs 7 segments (49 à 52), sont commandés par des 'buffers' du type HC 374, inclus dans l'interface (62). Un système de multiplexage permet de n'utiliser que deux boitiers pour l'ensemble des voyants et afficheurs. Ces voyants et afficheurs sont destinés à indiquer à l'utilisateur la dernière opération qu'il vient d'exécuter ou bien celle qui est en cours. Le rôle détaillé de chacun de ces voyants et afficheurs fait l'objet d'un paragraphe ultérieur.The indicator lights (10 to 32) as well as the illuminated digits, called 7-segment displays (49 to 52), are controlled by 'buffers' of the HC 374 type, included in the interface (62). A multiplexing system makes it possible to use only two boxes for all the indicator lights and displays. These indicators and displays are intended to indicate to the user the last operation that he has just executed or that which is in progress. The detailed role of each of these LEDs and displays is the subject of a later paragraph.
L'utilisateur choisit les différentes opérations qu'il veut réaliser sur l'appareil au moyen des touches de la face avant (33 à 48), ces touches activant les entrées de buffers inclus dans l'interface (62) et en liaison avec le microprocesseur. Le rôle de chacunes de ces touches fait l'objet d'un paragraphe ultérieur.The user chooses the different operations he wants to perform on the device by means of the keys on the front face (33 to 48), these keys activating the buffer inputs included in the interface (62) and in conjunction with the microprocessor. The role of each of these keys is the subject of a later paragraph.
Un microprocesseur du type Z80C (61) assure, grâce à un logiciel approprié implanté dans une mémoire du type 27C256 (63), la lecture des informations opéra¬ teur par l'intermédiaire des circuits d'entrée, la gestion des voyants et des afficheurs, ainsi que la génération des fréquences destinées à reproduire les notes de musique stockées dans la mémoire non volatile (64).A microprocessor of the Z80C type (61) ensures, thanks to appropriate software implanted in a memory of the 27C256 type (63), the reading of the operator information via the input circuits, the management of the indicator lights and the displays , as well as the generation of the frequencies intended to reproduce the musical notes stored in the non-volatile memory (64).
Etant donné le nombre de boitiers entrant en relation avec le microprocesseur, un 'buffer' bi-directionnel du type HC 245 est inséré entre le microprocesseur et ces mêmes boitiers. Un décodeur du type HC 138 permet au microprocesseur de choisir le boitier auquel il veut s'adresser, etGiven the number of boxes coming into contact with the microprocessor, a bi-directional 'buffer' of the HC 245 type is inserted between the microprocessor and these same boxes. An HC 138 type decoder allows the microprocessor to choose the box it wants to address, and

Ce voyant s'éteint dès que l'on active la fonction considérée.To access the second function of the preceding keys, one must first press the key (48) which has the effect of lighting the indicator (32). This light goes out as soon as the function in question is activated.
En mode de programmation on choisit la durée des notes en appuyant sur la touche (48) puis sur l'une des touches (34) à (41) choisissant ainsi le symbole cor- respondant à la durée de la note que l'on va program¬ mer. Les voyants (23) à (30) confirment la durée choisie. On peut ainsi programmer toutes les durées depuis la triple croche jusqu'à la ronde, en incluant les différents type de triolets ainsi que les valeurs liées ou les valeurs pointées.In programming mode, the duration of the notes is chosen by pressing the key (48) then one of the keys (34) to (41) thus choosing the symbol corresponding to the duration of the note that we are going to program¬ sea. The lights (23) to (30) confirm the duration chosen. It is thus possible to program all the durations from the 32nd note to the whole note, including the different types of triplets as well as the linked values or the dotted values.
L'altération éventuelle de la note est fixée par l'ap¬ pui sur la touche (33), la confirmation de celle-ci se faisant par les voyants (10) et (31).The possible alteration of the note is fixed by pressing the key (33), the confirmation thereof being made by the indicators (10) and (31).
La hauteur de la note considérée est fixée à l'aide de la touche (42) et l'on visualise l'octave choisie à l'aide des voyants (19) à (22).The pitch of the note in question is set using key (42) and the chosen octave is displayed using indicators (19) to (22).
Hors programmation, l'exécution du morceau est lancée en appuyant sur la touche (45). Elle sera stoppée momentanément en appuyant à nouveau sur cette touche, ou bien définitivement en appuyant au préalable sur la touche (48).When not programmed, the execution of the piece is launched by pressing the key (45). It will be stopped momentarily by pressing this key again, or definitively by first pressing the key (48).
Hors exécution un certain nombre de fonctions auxi- liaires sont disponibles. On y accède en appuyant d'abord sur la touche (48), puis sur l'une des touches (34) à (41).When not running, a number of auxiliary functions are available. It is accessed by first pressing the key (48), then one of the keys (34) to (41).
La touche (34) donne accès à la fonction de transposi¬ tion, et permet d'entendre la mélodie plus haut ou plus bas qu'elle n'a effectivement été entrée dans l'appareil. Cette transposition peut être fixée de demi-ton en demi-ton grâce aux touches (44) et (45), avec contrôle sur les afficheurs (50) à (52). La touche (35) déclanche l'envoi sur la prise audio (58), de séquences codées correspondant aux informa¬ tions du morceau préalablement entré dans la mémoire de l'appareil. Ce procédé est appelé sauvegarde numérique sur cassette. La touche (36) déclanche le processus inverse. L'appareil se met en attente d'un signal codé qu'on lui envoie sur la prise audio. Dès qu'il reconnaît le signal codé, il recharge le morceau de musique dans la mémoire non volatile (64). On peut alors le ré-écouter en fixant tous les paramètres désirés.The key (34) gives access to the transposi¬ tion function, and allows the melody to be heard higher or lower than it has actually been entered into the device. This transposition can be fixed from semitone to semitone using the keys (44) and (45), with control on the displays (50) to (52). The key (35) triggers the sending to the audio socket (58) of coded sequences corresponding to the information of the piece previously entered into the memory of the apparatus. This process is called digital tape backup. The key (36) triggers the reverse process. The device waits for a coded signal that is sent to it on the audio socket. As soon as he recognizes the encoded signal, it reloads the piece of music into the non-volatile memory (64). You can then re-listen to it by setting all the desired parameters.
La touche (37) permet de choisir le numéro du morceau que l'on veut programmer ou écouter. On peut en effet avoir au même instant quatre morceaux indépendants dans la mémoire. On fixe ce paramètre à l'aide des touches (44) et (45), avec un contrôle sur l'afficheur de gauche (49).The button (37) allows you to choose the number of the track you want to program or listen to. One can indeed have at the same moment four independent pieces in the memory. This parameter is set using the keys (44) and (45), with control on the left display (49).
La touche (38) permet de mettre en ou hors-service les tops sonores simulant le métronome. Ces tops ne seront entendus que pendant l'exécution du morceau. La touche (39) permet de régler avec précision la ré¬ férence en matière de fréquence de l'appareil. Δ l'ai¬ de des touches (44) et (45) et du contrôle visuel sur les afficheurs (50) à (52), on peut ainsi ajuster le 'LA' de l'appareil de 412 à 450 Herz. A chaque mise en service, la valeur usuelle, à savoir 440 Herz, est reprise par l'appareil.The key (38) is used to activate or deactivate the beeps simulating the metronome. These cues will only be heard while the song is playing. The key (39) makes it possible to precisely adjust the frequency reference of the device. With the help of the keys (44) and (45) and the visual check on the displays (50) to (52), it is thus possible to adjust the 'LA' of the device from 412 to 450 Herz. At each start-up, the usual value, namely 440 Herz, is taken over by the device.
Enfin les touches (40) et (41) permettent d'accéder à des airs de démonstration.Finally the keys (40) and (41) provide access to demonstration tunes.
