Bonjour,
oui bien sur voilà le code que j'utilise :
#include <frequencyToNote.h>
#include <MIDIUSB.h>
#include <pitchToFrequency.h>
#include <pitchToNote.h>

désolé si j'ai omis des info, j'ai rédigé un peu vite ce topic
dans le document README.adoc, il ne parle que de Linux.
Au début du fichier, il est mentionné que ça ne fonctionne qu'avec l'arduino 1.6.6, alors que j'ai la dernière version, la 1.8.3.
Je l'ai trouvé dans la page des releases mais c'est pareil le message d'erreur revient avec la 1.6.6
