Change tempo proportionally on playback?
Is there a way to change the tempo proportionally for a ritardando, instead of manually via system text? The purpose is for exporting a score as multiple MP3s at different tempos for instructional purposes.
For example, say the tempo of the piece is 100. For the last two measures I want to reduce the BPM to 75 (25% reduction in speed).
But I also want a recording of the piece at 200. So the last two measures would slow down to 150.
I know I could do this manually...I'm just wondering if there's an automated way?

Well, you can use the Play Panel to scale the overall tempo of the performance. I'm not sure if that is taken into consideration on MP3 export, but if not, you could create the MP3 by capturing the audio using Audacity or whatever.
There is now an automated way in the form of this plugin: https://musescore.org/project/tempostretch

Awesome...thanks! Will that also work when exporting the file as an MP3 recording?

It updates and changes all markers in the score. So yes, it'll also affect the export of said score

I just used it. Fantastic! If you made the plugin, thank you! And regardless, thanks for letting me know about it.

Minor update: the plugin will now also add a hidden tempo marker at the start of the score in case of a missing marker there. Thus allowing that part of the score to become stretched as requested as well.

The start of the score or the region being treated? How does it determine the exact location to look for one? Is "at the start of the score" unambiguous?

The hidden marking is start of score only. It's the only one I can add with certainty as the hardcoded 120 value from MuseScore is a given.
As for the thing shown in the dialog: If a selection is made, then I search backwards for a marking from the start of the selection.

Is it correct to say that the case, and the only case, when you insert it is when, searching backward from the selection, you found none?
