+# Un système UPIC pour un orchestre de gravures
+
+C'est un projet prenant pour source de création des gravures faites avec la technique d'eau forte sur plaque de zinc. Il inclut la transcription visuelle dans le champ sonore fréquentiel dont le mouvement du dessin fixe va altérer le comportement sonore dans le temps.
