摘要： An electronic musical instrument (1) simulates a stringed musical instrument such as a guitar. Musical sounds of appropriate frequency and envelope are provided. An oscillator (34) provides a reference clock frequency to a digital counter (38) which is controlled by touch circuits (46) and a digital circuit (36) to divide the reference clock frequency into an appropriate output frequency. An envelope control circuit (40) shapes the output frequency to simulate a stringed musical instrument.

摘要： Un instrument musical electronique (1) simule un instrument musical a cordes tel qu'une guitare. Les sons musicaux de frequence et d'enveloppe appropriees sont produits. Un oscillateur (34) fournit une frequence d'horloge de reference a un compteur digital (38) qui est commande par des circuits de toucher (46) et un circuit digital (36) pour diviser la frequence d'horloge de reference en une frequence de sortie appropriee. Un circuit de commande d'enveloppe (40) forme la frequence de sortie pour simuler un instrument musical a cordes.
