This invention is a display system for an automatically tuned stringed instrument, individually or simultaneously, the frequency of each string of the instrument. Each string is provided with a transducer (26) for providing a signal to a processor (50) for determining the measured frequency. The processor (50) further generates a display signal and an actuator control signal from the measured frequency. An actuator (90) is controlled based on the actuator control signal. The display (72) is controlled based on the display signal. The system provides for using the display (72) to manually tune the instrument to within the operating range of the automatic tuning system.

La présente invention concerne un système d'afficheur destiné à un instrument à corde s'accordant automatiquement, l'afficheur donnant individuellement ou simultanément la fréquence de chaque corde de l'instrument. Chaque corde est pourvue d'un transducteur (26) délivrant à un processeur (50) un signal lui permettant de déterminer la fréquence mesurée. A partir de la fréquence mesurée, le processeur (50) génère en outre un signal d'afficheur et un signal de commande d'actionneur. Cet actionneur (90) est commandé par le signal de commande d'actionneur, l'afficheur (72) étant commandé par le signal d'afficheur. Ce système permet d'utiliser l'afficheur (72) pour faire un accordage initial de l'instrument dans les limites de fonctionnement du système d'accordage automatique.
