Global tempo change
I made some pieces with TempoChanges, but the result is way too fast for me to play along with :-(
I can practice, or change all the tempo in the pieces.
From my searches Musescore can't do a global change to all tempi in a piece (all tempo * 150%, or all tempo * 50%).
I want to check there is currently no way to do this before I consider trying my hand at a plugin. Anyone?
The TempoChanges code looks pretty complicated for my little brain, but I'll bet studying it will be a good place to start.
There is a plugin specifically for this already, see https://musescore.org/en/project/tempostretch
In case you weren't already aware, you can temporarily change the overall playback tempo using the Tempo slider in the Play panel. (If the Play panel isn't already visible, go to View | Play Panel or press F11).
The Tempo slider affects playback of the current score (and you can even adjust it during playback), but it isn't saved when you save the score.
These are both great options, thanks! Good thing I asked.
I like that tempostretch can do a selection, and supports undo. Great.
