losing tempo

Jim Newton
It happens to me often, but I don't know exactly how to reproduce it.
I save a score with a tempo text on the first note/rest of the first measure.
After saving and reopening the next day, the visible text is still there, but when I press play, it plays much faster than the text indicates.  If I delete the text and recreate it it works correctly.

I'm attaching such a file which has the text, but for which the text does not seem to have any effect on the played tempo.

andante.mscx

Could this be a problem in the xml-out of the tempo text?

This piece plays at Quarter note = 37 for me. Could it be that you changed the speed in the Play Panel?

On second look.  This score does not seem to exhibit the problem.
As I said, I don't really know how to reproduce it.  I'll post a score demonstrating the problem, next time it occurs.

The marking says 37, not 60.  And indeed, in plays at 37, not 60.

Re: losing tempo

yes as i said, this file does not exhibit the problem.  Sorry about the false alarm.
Next time I see it happening, I'll try to catch a version of the file and let you know.

Hi Nicolas, maybe I have reproduced the problem.  For me this score shows a tempo of 37 but plays at something I'll guess is about 60.  What does it play like for you?

When I delete the tempo text and create it again, I get this difference in the xml file.

I think I see how to reproduce this.
Open the attached andante.mscz file.
Press Play and you'll see it plays at 60 bpm.
How select the tempo text at the first measure by double clicking.
Change the text to 37.
Click outside the select region to deselect, and exit text edit mode.
Now press play.

For me it still plays at 60bpm, not at 37.

As I said before, it only follows the text in your tempo marking if the "Follow text" option is set in the Inspector, which it isn't in this case.  And the text has to be followable - MsueScore won't try to guess what "Not too fast" means, etc.  For tempos where following the text does not make sense, instead, the tempo field in the Inspector is used.
