I've read il the manual that it's possible to play midifile.
Does-it possible to print on the screen the note played ? or other information about the file ?
No. That way you would have to either parse the midi file yourself, or use any library that can do this for you. There's surely one out there, that provides both information, and implementing an external library with INLINE/DECLARE is quite easy.
Thanks for this quick answer. I just foud a command line utility that convert a midi file to a text file. Just need now to find a way to include notes in an array.
