Problem with Tempo and Time Signatures when importing MIDI files produced by a DAW #10962

Open Darkspeen opened 2 years ago

Darkspeen commented 2 years ago

Describe the bug Exporting a MIDI file from a DAW and then tryîng to import it to MuseScore produces tempo and time signature issues. i.e. Tempo always seems to stick to 120 BPM and Time signature remains on 4/4

MIDI files exported from MuseScore or other notation software seem to behave properly however and the key recognition along with multiple staves and voices seem to work fine as well.

To Reproduce Steps to reproduce the behavior:

  1. Open a DAW and record some MIDI information on it.
  2. Export the MIDI file of the project
  3. Open MuseScore
  4. Import MIDI
  5. See the error described above: BPM sticks to 120 mostly and remains on 4/4

Expected behavior While quantization is a matter all along, it would be expected that the information at least reflects properly in terms of Tempo and Time Signature changes.

Additional context This was tested exporting the MIDI file from the following DAW's:

All yielding the same behaviour.

@Darkspeen Hi! Can you attach the midi file illustrated that issue please?

I've tested using MIDI file from ProTools with a different tempo marks (113, 98, 73) and it opens fine in MuseScore4

Thanks!

@DmitryArefiev Hi! Yes, sure! GitHub doesn't accept MIDI files, so I'll be sending the file through a drive link. And also that's weird, but it's interesting nonetheless. Please do tell what you can find!

@Darkspeen Thanks for the files. I zipped and attached to the description. Tempo changes and Time Signatures are shown in Pro Tools but not in MuseScore 4.

The same issue in MuseScore 3 and MuseScore 2.

Do know for now where the problem is (export settings, midi format etc.).. Let's leave the bug in open state.

Thanks!

Since this is an issue with both MS2 and MS3, I'm going to bump until 4.X. Will reopen when 4.0 is out.

I would assume this is because the file in question does not contain the changes in each track, instead putting them only in a "control track" at the beginning of the file. For historical reasons MuseScore has not worked that way - not for import or export. It's been a pretty common request, though.
