playback tempo changes without doing anything

• Jan 14, 2023 - 22:32

I have the newest 4.0 and when using playback the tempo will change without me doing anything. In my piece I have playback set to 96, but after the 2nd ending it changes to 76. Any clue why this is happening?


I am having this problem too! Have you found any solutions? I'm going to have to go back to 3.0 if I can't fix it, which would be sad because I like a lot of the other new features. Mine is switching back and forth between tempos nearly every measure, it's terrible.

Yes, the fermatas are definitely the problem. If I remove all the fermatas it plays correctly. I've been playing around with this and it's basically the more fermatas, the worse the tempo issues are.

I don't think the fermatas work correctly at all. As far as I can tell, the fermata causes the tempo to change to 1/2 what it was, which might be fine for very simple compositions, but if you have multiple parts with the fermata falling on different duration notes, it results in strange behavior. I'm attaching a simple test case. The fermatas in the second measure are meant to lengthen the last beat of the measure. But because the note in the baseline is a whole note, it apparently gets applied to the first beat of the measure and messes up the rhythm of the upper line, which ought to be steady quarter notes until the last beat.

Looking closer, it seems a slightly different from simply not returning to the original tempo. Though all fermatas are set at 200% stretch, they actually play at 1/3 the original tempo, then it doubles tempo at the end of the fermata, meaning it's slower than before. E.g. if original tempo is 75 bpm, the fermata plays at 25 bpm, and then continues at 50 bpm afterwards. I created a new score with a couple of bars and a fermata and it behaved normally so I'm at a loss as to what is different with this one.

I tested by turning on the metronome. The metronome click is so erratic as to sound more like a clave. Doesn't make a difference if tempo markings are left as is, or removed. Borders on bizarre.

I had the same problem after rewriting some notes form voice 2 to voice 1, making some fermatas disappear by deleting the attached note (not the fermata), and then changing the stretch of the visible fermatas.
Apparently the fermatas that disappeared by the attached note in voice 2 does not truly disappear. I noticed this when I removed all notes from voice 2 in a measure. The fermata would then reappear in approximately the same spot. The measure that changed the tempo of the piece had such a "hidden fermata". Removing this fermata fixed the issue for me.
