Playback speed issue. Weird/irregular tempo changes. Suddenly very fast, then slow.
When I open a MS2 score in MS3, then, when I play it back, I notice some weird tempo changes. From slow to very fast, not the way it should be. This way my MS2 scores sound ridiculous in MS3 and it would make them worthless for playback.
For instance, my latest score, No 266, when you download it and open it in MS3 and play it back, you will notice the difference when it is played back in MS2 (try online or by opening/play back the score in MS2).
It also happens in places where there are no tempo changes, but, for example a fermata with a breath pause. This is the case in score no.264.
By the way, not only those scores, but many more, if not all have that problem. I tried many more and they all have the same issue.
(I'm using the AppImage of MS3 on Ubuntu Studio; a Linux distribution/operating system)
