this is because this midi uses a custom/unknown instrument, try another midi

[PaxiTheAlchemist]

Ah, I see. in that case, what if there was a way to modify an unknown "track" whereas the user could choose an instrument to replace the unknown instrument prior to generation. Obviously, I do not expect this to be implemented right away, but this would be a good solution to put into the application. Examples of this sort of thing being used are on various other midi parsing applications and platforms

quand j'importe mon fichier midi et qu'il le converti il me le converti qu'avec un seul instrument (la harpe) sa me soule je vois plein de gent le faire est ils on 10000 instrument ses soulant .

When I import my midi file and it converts it, it only converts it with one instrument (the harp).
