Instant crash when importing MIDI file (example provided)
Hi, I can't get Musescore (last revision, OS: macOS 10.16, Arch.: x86_64, MuseScore version (64-bit): 3.6.2.548020600, revision: 3224f34) to open some MIDI files produced by Ableton Live (Ableton Live 11.0.2 Suite, last build). It instantly crashes. Enclosed file shows an example of something played on a piano, single track, which makes Musescore instantly crash, either on load if I double click it from file manager or when I import it from menu.

That seems to be a basically empty MIDI file, Windows Media Player doesn't play it
Same issue as https://musescore.org/en/node/319840 I guess

VLC Media Player can't play it either. Broken.

There is indeed no program change event present at the start of that file.

Maybe MuseScore should assume Piano then?

It is not empty, it contains 614 bytes easily seen via more or any editor, but I guess it is either corrupted in some way, or considered as corrupted by Musescore. It is produced by Ableton Live, so if it is really corrupted, I have to escalate to them, but I would need to be sure.

That's why I wrote "basically empty". Without such a program change event at the beginning it is at least incomplete (as far as MuseScore is concerned, and VLS and Windows Media Player too)
I hate to bring this up, but OP admits that the file is broken from the start. The problem he reports is not that he can't play or import it, but that it causes a crash.

MuseScore should not crash I guess, but garbage in, garbage out
(and no, the OP did not claim the MIDI to be broken)

No, he didn't, you're right.

I didn't "admit anything from the start". I report a problem, which can be caused either by Musescore or by Ableton Live. I've not read MIDI standard, so I believe you if you say it's Ableton.
Besides, I thought exception handling was considered a good practice. Anyway, I will try to manually sort this file out and to report the bug to Ableton.

There are two problems. The Ableton-produced file is invalid, and MuseScore crashed rather than recognize that. It's both, not either.
Same problem here
The same thing happened to me, but the MIDI file is from Signal and the program to open it is Sforzando. After looking at it in a hex editor, it's probably the fact that the metadata is missing. I have attached a file with the same problem.

I have no problem to open it in Mus 3.7.
