Gradual tempo error

I have a project in which a ritardando is actually speeding up. It’s quite a bit more obvious in my full project but is still demonstrated in the cut-down one below.

It seems I can fix the behaviour by removing the fermata in bar 2.

Thoughts?

Where do you think it is speeding up?

At the rit: beat 2 of bar 4.

It’s not indicated in the tempo map but still happens.

Odd indeed, and definitely not what the tempo lane automation shows - it definitely leaps up to something like 170 bpm suddenly and back down. I thought to maybe just wiggle the automation points down and then back to where they were and it seems to have fixed it. Ghost in the machine?

Hi @DanielMuzMurray,
quite an odd behaviour indeed. It seems that the fermata makes the rit. forget what is the tempo corresponding to the fermata bar (q=80) in playback (even if in the key editor all looks ok), and seems instead to be influenced by the tempo set before the fermata:
I tried setting the first tempo Fanfare to q=300 and the rit. starts even faster!
If you set the Fanfare tempo to q=80, the rit. works as expected.

Two ways to correct this (beside the suggestions above) is to reiterate the q=80 after the fermata (you can then deactivate its visibility), or set the initial tempo for the rit. to 80
