With your help, now I have got some sound ! ! ! Yeah ! :lol:
But the synchronization is the problem now… I have created a thread, and used the wait instruction to… wait for the next event, at the right time, and with a maximum priority, the play of midi file is, you can imagine, not slow at all, but the drummer has lost 20 years of practice :lol: Now I’m looking for a way to do the synchronization faster…
