music21

问题 I'm trying to use music21 to convert multi-track midi files into array of notes and durations per each track. For example, given a midi file test.mid with 16 tracks in it, I would like to get 16 arrays of tuples, consisting of (pitch, duration (plus maybe position of the note)). Documentation for music21 is rather difficult to follow, and I would really appreciate any help on this.. 回答1: There is more than one way to do this in music21, so this is just one simple way. Note that the durational

问题 I have some notes and what I want is create the MIDI file with Flute instrument. But what happens is that the output MIDI file plays Piano, instead of Flute. I tried other instruments, but it's always the same, Piano. What is going on?

For example, if, in my MIDI file I have two tracks that use piano I want to be able to print the notes, change the instrument, etc. Right now I have a file with multiple tracks (drums, trumpet etc.) and I am just messing around with it trying to replace a certain instrument with another. However, when I do I get an error and some of the tracks are removed completely
