MuseScore MIDI Import error - while reading Samplitude MIDI Export file
Hi,
I exported a MIDI file with Samplitude Music Studio 2014.
Due to an error in creating MIDI files, Samplitude inserts unused bytes between Tracks.
( newer versions up to the actual Samplitude release may still have this bug .. )
So MuseScore fails to load the exported MIDI file.
=> MuseScore Error message: "bad midifile: MTrk expected"
As Windows' MediaPlayer plays the MIDI file with no error,
I tried to find out how to fix the bug on loading a MIDI file.
Fix looks like this:
- Fileread pointer should point to "MTrk", but there is no, so ..
- step up for up to 8 bytes to try to find "MTrk" (loop byte for byte)
- If not found (or EOF ..), stop reading => file error
- if found, continue reading file
MuseScore Version: 3.5.2.311459983 under Windows 10 (actual stable release)
Cheers, Peter

So seems to be a Windows-issue? Maybe check a nightly build of the upcoming version 3.6.0 yourself to see if it's fixed for you with Windows.

Yes, looks to be a "Windows only" issue.
I was able to load the mscz, uploaded here.
MuseScore complained about "file was created with newer version"
but finally the Score showed up well, and is usable for me, thanks !

My selfbuilt 3.6 dev version happily loads it as well (without error message).
I'd wait for the official beta and then retry in that.

Also, QtWebEngineProcess.exe didn't close after terminating the program.
I had to manually close 5 instances of this in task manager, after several program starts.
