File altered on export

Post by FalCT60 »

Hello everyone,
I am new in MusE, I discovered it a few days ago and gave it a try. I compiled v 4 on Ubuntu Focal.
The simplest test I did, just to see what happens : download a midi file, then export as a renamed version - nothing added or modified in any way by myself.
Well, the exported file is not the same as the original one ! Notes are missing, it sounds awful !
Attachment
Hallelujah.zip
(4.49 KiB) Downloaded 145 times
contains both the original and exported files.
I must have done something wrong, but I am unable to find what.
Can anyone help me ? I did not find anything related in the manual, wiki or elsewhere on the web.

Hi,

I can confirm the issue: When I export the same midi file with MusE 4 I get similar "dropouts" in the midi.
However, if I use the current development version it sounds like the export is Ok. I looked in the ChangeLog but could not find any related fix but there looks to be one...

You can try the latest AppImage (or build the latest master) if you want to verify this.
We will likely make a 4.0.1 fix release soon.

Do let us know if you have any other issues or questions!

Hello,
I did not expect such a fast answear, many thanks.
I thought it was a matter of some bad settings from myself.
I am going to try the latest master.
And then report.
--- edit ---
I did a git pull, then ./compile_muse.sh from within src, and finally sudo checkinstall make install from within build, but unfortunately get the same behaviour.
I think I am going to be patient until the update is available.
Notice : it is the first program I compile, until then I only used the apt method, so not only am I discovering MusE but also git and building, compiling, aso.

Hmm, okay.
Well, while export is not the most used function in MusE I don't think there are any settings that could produce such issues.

This could mean the problem is still there but a bit more nefarious and only manifests itself under certain conditions. I will poke it a bit and see if I can make any sense of this.

If you want to try helping it would be good information if it is possible to minimize this song and still have trouble exporting.
Focusing on only a specific error and see if it persists when it is the only thing left in the song would be best.

OK, not sure if I really understood, but it seems this only occurs with track 1 (and its clones, if I duplicate it), but not with other tracks.
As I am not able to read music, I cannot be sure of anything.
Now... what can I really do ?

Hello all,
I am not sure, but it seems the problem is related to signature - though I am not able to prove it.
6/8 seems not to suit the way the notes are scored.
Maybe some high-skilled musician could confirm ?

I've looked some more into this and the reason is not yet clear to me.

What I have found is that muse build in RELEASE mode has much more problems than the same code built in DEBUG mode.
This usually means we have uninitialized variables, but this far I haven't been able to create a test case that is manageable for me to dig deeper.

I should have said so directly but it would be good if you created a bug on github
https://github.com/muse-sequencer/muse/issues, that way it is easier for us to keep track of this issue.

I did not open an issue, as I was quite sure it was because of something I did wrong.
So, that is done now.
The weird thing is that I could not attach the zip file.

Very late reply in the github issue report.
I could not reproduce it.

Watch for any necessary changes if the OP is still around
and we can figure out what went wrong.
