Midi files with multi channels doesn't work using MIDI.Player.Loadfile

[KomeijiSatori]

I have a midi file with three channels(both acoustic_grand_piano), when calling MIDI.Player.Loadfile, it only plays one track.
Another problem is that the player dropped the very first note of the midi file, and the note is at time 0:00. After I move the first note 2 seconds later then it sounds good.
And also I checkout to a branch called "abcjs", and I change the code to the newest commit, the two problems are resolved. Since there're too many commits(29commits ahead of HEAD), so I can't figure out which important part has been changed. But that commit has a problem with pause function, which will play one or two unexpected notes after 3 or 4 seconds after resume.

What's more is another project Color Piano (https://galactic.ink/piano/), which is awesome and it doesn't have any of issues described above. But it seems not open source. So @mudcube , would you mind creating a repo of that project? Much thanks!

yes. same problem.

[KomeijiSatori]

yes. same problem.

@MX-Qulin Hi, friend, I solved this problem by replacing the whole js/midi folder to single midi file used by https://galactic.ink/piano/ , and the problem resolved, cheers!

well, as i use the brach abcjs if this repo, it can't work...

i'll try your solution. Anyway, thank you:)

I solved this problem

@KomeijiSatori Do you mean that https://github.com/KomeijiSatori/3d-piano-player would be able to play MIDI files with several instruments without problems if the soundfont directory contained those instruments?

http://midi.chongliu.me/ redirects to a blank page. When I run https://github.com/KomeijiSatori/3d-piano-player locally (which requires starting Chromium with the --allow-file-access-from-files flag) after having replaced one of the MIDI files by a MIDI file with several instruments, all instruments still sound like the piano. Then I realized that https://github.com/KomeijiSatori/3d-piano-player/tree/master/soundfont doesn't contain many instruments. I haven't yet tried adding instruments there or making a MIDI file with only the two available instruments.

Hi Page, I mean I solved the problem of playing mulitple tracks, but the soundfont is not supported. If you want the right mapping of the instruments, it requires a lot deeper and embeded development of the code.
