problemi convesione files midi con libreria tone

International Italiano Software
1

ciao a tutti
non riesco a risolvere un problema per far suonare Arduino con i files midi.
Con la libreria Tone ed in particolare con RTTTL riesco a trasformare un file midi in rttl; basta caricare il file su questo sito e incollarlo nel codice.
Altri tipi di operazioni riesco a farle tranquillamente, come scrivere "a mano" la musica, con la libreria Tone e non.
Invece, per quanto riguarda delle parti musicali più complesse, non riesco a risolvere un problema: convertire dei files midi in questo codice di cui non conosce sinceramente il nome

continua qui il codice
La mia domanda è: come faccio a convertire dei files midi in questo codice 0x77, 0x00, 0x2a, 0x84, 0x05, 0xbb, 0x90, 0x18, 0x40, 0xc3, 0x6c, 0x50,etc. che non so nemmeno come si chiama?
grazie

Midi prevede il suonare piú frequenze in contemporanea. Tone non lo prevede.
Ciao Uwe

infatti con tone suono una nota alla volta, con il link che ho postato, Arduino diventa polifonico

ciao a tutti

Ti invitiamo a presentarti (dicci quali conoscenze hai di elettronica e di programmazione) qui: Presentazioni
e a leggere il regolamento: Regolamento

5

ops scusa, avevo letto il regolamento ma non mi ero ancora presentato.
con i collegamenti e le basi non sono messo male, il mio problema è questo codice, la parte dopo PROGMEM che non riesco a capire di cosa si tratti e come posso creare musiche con questo tipo di codice

6

per esempio
questo codice suona tranquillamente collegando solamente arduino alle casse, non occorre nessun shield.
quello che vorrei fare è comporre io una musica ma non riesco a capire con quale metodo
