The score playback is often much slower than actual performance. When playing in the app, I can set the tempo - in this case to ratio 150- so the playback sounds correct, but it would be better to be able to enter a metronome setting from the actual score, i.e a critchet (quarter note) value, Thanks
In December, there was a post on the blog (in French) saying that they fixed a bug with recognition of the "quarter = value" tempo mark. You'll have to wait for next release.
